What is Radon and Why Does Illinois Law Care?

Radon is a naturally occurring radioactive gas that seeps into buildings from soil and rock beneath foundations. The Environmental Protection Agency (EPA) classifies radon as a Class A human carcinogen—the same category as asbestos and tobacco smoke. In Illinois, long-term radon exposure is the second leading cause of lung cancer after smoking.

The Illinois Department of Public Health estimates that roughly 1 in 3 Illinois homes exceed the EPA’s recommended action level of 4 picocuries per liter (pCi/L). Because radon is colorless, odorless, and undetectable without specialized testing, legislatures and regulators treat radon disclosure as a critical habitability issue, not optional property management.

Illinois codified radon disclosure requirements in the Radon Awareness Act (420 ILCS 46), which became effective in the 1980s and has been refined through updates. Unlike some habitability defects (mold, structural damage), radon defies visual inspection. This is why Illinois law places the burden on landlords to affirmatively disclose test results or the absence of testing.

420 ILCS 46: The Legal Framework

Illinois landlords must comply with three overlapping requirements under 420 ILCS 46:

1. Disclosure Before Lease Execution

420 ILCS 46/5 requires landlords to:

• Provide radon information to prospective tenants in writing before they sign a lease or rental agreement.
• Disclose all radon test results conducted on the property within the past 12 months (or available from prior testing).
• Inform tenants whether testing has or has not been performed — silence or omission violates the statute.
• Provide the EPA’s “Consumers Guide to Radon Reduction” or equivalent radon awareness materials in writing.

The statute does not mandate that landlords conduct radon testing. However, it does mandate that landlords disclose whether testing has occurred and what results exist. This distinction is critical: a landlord who has never tested and discloses that fact is compliant; a landlord who has tested and fails to disclose is in violation.

2. Written Lease Acknowledgment

420 ILCS 46/5 requires that the written lease or rental agreement include:

• A specific radon warning statement provided by the Illinois Department of Public Health, OR
• A statement acknowledging that the tenant received radon information and understands radon risks.

The statute provides a model warning form. Landlords are not required to use it verbatim, but the lease must contain language substantially similar to the following:

“RADON GAS: Radon is a radioactive gas that comes from the decay of uranium in soil and rock. It can get trapped in buildings and create health risks from long-term exposure. Testing is the only way to know if radon is present.”

Many landlords fail this requirement by omitting radon language entirely or including only vague references. Illinois courts have upheld tenant claims that missing or inadequate radon warnings render the lease unenforceable or create statutory violations subject to damages.

3. Continuous Disclosure Obligation for Current Tenants

Landlords must disclose new radon test results to current tenants, even mid-lease. If a landlord conducts radon testing after a tenant has moved in, results must be disclosed within a reasonable time. Withholding test results from sitting tenants—for example, delaying disclosure of a test showing radon above 4 pCi/L—can trigger:

• Tenant right to terminate the lease without penalty.
• Rent abatement claims.
• Complaints filed with the Illinois Department of Public Health or state attorney general.

Radon Testing: Not Mandatory, But Practical

Illinois law does not require landlords to test for radon. However, strategic testing protects landlords in several ways:

Why Testing May Protect You

• Demonstrates due diligence: A documented test showing levels below 4 pCi/L proves radon is not a habitability defect, reducing tenant complaints and enforcement risk.
• Prevents tenant-ordered testing costs: If a tenant orders testing after a landlord’s disclosure of “no testing performed,” and results are elevated, tenants may demand the landlord pay for remediation or pursue lease termination. Landlord testing first avoids this surprise.
• Supports lease enforcement: Courts are more likely to enforce leases and evictions if the landlord has proactively disclosed known conditions.
• Reduces liability exposure: If a tenant or their family develops health issues, documentation of low radon levels or proper disclosure strengthens the landlord’s defense in any tort claim.

Testing Standards and Protocols

If you choose to test, Illinois Department of Public Health recommends:

• Use an EPA-certified radon measurement professional. Do not rely on home inspection general radon screens; they are often inaccurate.
• Conduct testing for 48 hours to 7 days using passive (charcoal canister) or active (continuous monitor) devices.
• Test the lowest livable level — typically the basement or lowest occupied room.
• Follow EPA protocols (listed in EPA’s “Radon Measurement Proficiency Program”).
• Keep all test results and certification documents for at least 3 years.

Test costs typically range from $150–$400 per property, significantly less than the cost of defending a tenant complaint or facing lease termination claims.

What Must Be Disclosed to Tenants?

If You Have Tested

Disclose all results in writing, including:

• Test date and location (e.g., “basement, main dwelling”).
• Radon measurement in pCi/L.
• Comparison to EPA action level (4 pCi/L).
• Any remediation steps taken (if results were elevated).
• Name and certification of the testing professional.

Example disclosure:

“A radon test was conducted on [date] in the basement of the property. The result was 2.8 pCi/L, which is below the EPA action level of 4 pCi/L and poses minimal health risk. Testing was performed by [Professional Name], EPA-certified radon measurement professional.”

If You Have Not Tested

Disclose in writing that no radon testing has been performed and provide radon awareness information from the EPA or Illinois Department of Public Health. Example:

“No radon testing has been performed on this property. Radon is a radioactive gas that can accumulate in buildings. Testing is the only way to know radon levels. The tenant may request radon testing at tenant’s expense, or the landlord may agree to conduct testing. Additional information is available from the EPA and Illinois Department of Public Health.”

If Results Exceed 4 pCi/L

If radon levels are at or above 4 pCi/L, you must:

• Disclose immediately in writing.
• Inform tenants of EPA-recommended mitigation strategies (sealing cracks, improving ventilation, installing radon mitigation systems).
• Provide contact information for EPA-certified radon mitigation contractors.
• Clarify whether the landlord will fund remediation or whether the tenant may request lease termination.

Elevated radon can constitute a habitability defect under Illinois common law, even if the lease is silent. Tenants have remedies including rent abatement and lease termination if a landlord fails to remediate or disclose.

Compliance Checklist for Illinois Landlords

Use this checklist to ensure compliance with 420 ILCS 46:

Compliance Task	Deadline / Timing	Documentation	Responsibility
Conduct or obtain radon test results	Before first tenant move-in (optional, but recommended)	Test report with date, location, result (pCi/L), tester name	Landlord or certified professional
Write radon disclosure (if tested or not tested)	Before lease execution	Written disclosure letter or lease addendum	Landlord
Provide EPA radon information	Before lease execution	Copy of “Consumers Guide to Radon Reduction” or equivalent	Landlord
Include radon warning in lease	Before lease execution	Signed lease with radon warning language	Landlord
Obtain tenant acknowledgment / signature	Before lease execution	Signed disclosure or lease with date and tenant initials	Landlord (secure signatures)
File or maintain records	Ongoing; retain 3+ years	All disclosures, test reports, tenant signed acknowledgments	Landlord
Disclose new test results to current tenants	Within reasonable time after testing	Written notice with test results and date	Landlord
Remediate (if results ≥4 pCi/L)	Within reasonable time; vary by lease terms	Mitigation contractor reports, follow-up test results	Landlord (if obligated by lease)

Penalties and Legal Consequences for Non-Compliance

Statutory Violations Under 420 ILCS 46

Failure to comply with radon disclosure requirements can result in:

• Lease voidability: Tenants can terminate leases without penalty if radon information was not disclosed before lease execution. Unlike some habitability defects, tenants do not need to prove harm; the omission itself is violation.
• Statutory damages: While 420 ILCS 46 does not specify a damage amount, courts have awarded damages based on breach of statutory duty and implied covenant of habitability. Typical awards range from $500–$5,000 for failure to disclose, plus attorney fees.
• Rent abatement: Tenants in properties with elevated radon can demand rent abatement if the landlord fails to remediate or disclose. Some Illinois courts have upheld abatement of 25–50% of rent until radon is mitigated.
• Attorney fees: Prevailing tenants can recover attorney fees from landlords in radon cases, particularly if the violation was knowing or reckless.

Regulatory Enforcement

The Illinois Department of Public Health enforces radon disclosure requirements. Enforcement actions include:

• Complaint investigations: Tenants can file complaints with the Department of Public Health. The agency investigates and may issue citations.
• Cease-and-desist orders: Persistent violations can result in cease-and-desist orders prohibiting property rental until compliance is achieved.
• Administrative fines: While 420 ILCS 46 does not specify fine amounts, the Department of Public Health can pursue penalties under general administrative law (typically $500–$2,000 per violation).
• License or registration suspension: If your state requires property management licensing, radon violations can be grounds for suspension or revocation.

Common Law Habitability Claims

Beyond statutory violations, elevated radon can support habitability claims under the Illinois Residential Tenants Rights Act (765 ILCS 742). Tenants can assert that radon above EPA action levels renders a property uninhabitable and pursue:

• Repair and deduct remedies (tenant pays for mitigation, deducts from rent).
• Constructive eviction claims (abandonment and damages).
• Breach of implied warranty of habitability (lawsuit against landlord).

These claims can result in damages significantly exceeding statutory penalties.

Multi-Unit Properties: Higher Stakes

Landlords with 2–75 units face elevated scrutiny because radon in one unit can affect adjacent units. Illinois enforces stricter disclosure requirements for multi-unit properties:

• Building-level disclosure: If radon testing has been performed anywhere in the building, results must be disclosed to all prospective tenants, not just those in the tested unit.
• Unit-specific testing: Radon levels can vary significantly between units. Testing should occur in units being rented or soon to be rented, or the landlord should disclose that unit-specific testing has not been performed.
• Common area mitigation: If radon levels are elevated, mitigation may require ventilation or sealing in common areas, which creates cross-unit compliance burdens.
• Inspection access: Tenants in multi-unit buildings have stronger rights to request radon inspection access, and landlords cannot deny access without creating presumptive violations.

For self-managing landlords with 2+ units, robust record-keeping and proactive testing are essential liability controls.

Remediation Options and Landlord Obligations

EPA-Recommended Mitigation Methods

If radon levels exceed 4 pCi/L, the EPA recommends:

• Sub-slab depressurization: Installing a PVC pipe through the foundation to vent radon directly to the roof (most effective; costs $800–$2,500).
• Caulking and sealing: Sealing foundation cracks and gaps (low-cost, $100–$500; limited effectiveness alone).
• Improved ventilation: Installing exhaust fans or increasing air exchange (moderate cost, $200–$1,000).
• Drainage improvements: Installing perimeter drains or sump pumps to reduce soil moisture (cost varies; $500–$3,000).

Who Pays for Mitigation?

Illinois law does not explicitly assign remediation costs. Instead, it depends on:

• Lease terms: The lease may specify that the landlord is responsible for radon remediation. If the lease is silent, courts apply implied habitability obligations.
• Common law habitability: Courts have held that landlords must remediate radon if levels are substantially above EPA action levels, treating it as a habitability defect. Tenants can repair-and-deduct if landlords refuse.
• Tenant choice: If radon is disclosed and documented, some leases allow tenants to elect lease termination rather than wait for remediation. Landlords can negotiate this language.

Best practice: Include explicit language in your lease addressing radon:

“If radon testing reveals levels at or above 4 pCi/L after lease execution, the landlord will [remediate at landlord’s expense / offer lease termination / share remediation costs]. Tenants may not unilaterally withhold rent for radon-related concerns without following the notice and cure procedures in this lease.”

Post-Remediation Testing

After mitigation, conduct a follow-up radon test to confirm effectiveness (typically 7–30 days post-remediation). Disclose follow-up results to tenants. If levels remain elevated, further mitigation is required.

Real-World Compliance Scenarios

Scenario 1: New Lease, No Prior Testing

Situation: You are renting a 3-unit building for the first time. No radon testing has been performed.

Compliance steps:

1. Decide whether to test. (Recommended: test at least one unit to establish baseline.)
2. If not testing, write a disclosure: “No radon testing has been performed. The tenant may request testing or the landlord may arrange testing.”
3. Provide EPA radon guidance document in writing.
4. Include radon warning language in lease.
5. Obtain tenant signature acknowledging receipt of radon information.
6. Retain all documents for 3+ years.

Outcome: Compliant. The lease is enforceable, and you have documented disclosure.

Scenario 2: Testing Reveals 6.2 pCi/L

Situation: A radon test on your 2-unit property shows 6.2 pCi/L in the basement (above 4 pCi/L action level). Unit 1 is currently occupied; Unit 2 is vacant and ready to lease.

Compliance steps:

1. Immediately disclose the result to the current tenant in Unit 1 in writing, including a copy of the test report.
2. Notify the tenant that radon levels are above EPA action level and explain health risks.
3. Offer remediation options or lease termination (depending on your lease and preference).
4. Engage an EPA-certified radon mitigation contractor to install sub-slab depressurization or equivalent.
5. Conduct follow-up testing 7–30 days after remediation.
6. Before leasing Unit 2, disclose the original test result (6.2 pCi/L), the mitigation work completed, and the follow-up result (e.g., 2.1 pCi/L post-mitigation).
7. Provide radon warning in Unit 2 lease and obtain tenant signature.
8. Document all communications and test reports.

Outcome: Compliant. You have disclosed known conditions and taken reasonable steps to remediate. The follow-up test protects you from future claims.

Scenario 3: Tenant Requests Testing; Results Are Low

Situation: A tenant in your property requests radon testing at their expense. The test returns 1.8 pCi/L (below action level).

Compliance steps:

1. Obtain a copy of the test report from the tenant (or hire your own certified professional if the tenant’s test is questionable).
2. Disclose results in writing to the tenant: “Testing conducted [date] shows 1.8 pCi/L, below EPA action level.”
3. Document that you have disclosed the result.
4. If you lease to a new tenant afterward, disclose the prior test result and explain it was below action level.

Outcome: Compliant. Low radon results are favorable and should be prominently disclosed to future tenants to support leasing.

Frequently Asked Questions

Q1: Is radon testing mandatory in Illinois?

A: No. 420 ILCS 46 does not require landlords to conduct radon testing. However, it requires landlords to disclose whether testing has been performed and what results exist. Tenants can request testing, but landlords are not obligated to conduct it unless the lease specifies otherwise. Best practice is to test at least once to establish baseline conditions and reduce liability exposure.

Q2: What happens if I sign a lease without including radon warning language?

A: The lease may be voidable at the tenant’s election under 420 ILCS 46. Tenants can terminate without penalty, and you will have no legal recourse if the tenant claims they were not informed of radon risks. Additionally, the tenant could pursue damages for statutory violation. Always include radon warning language in all residential leases.

Q3: I did not disclose radon to my current tenant. Can I disclose now?

A: Disclosing now is better than not disclosing, but it does not cure the original violation. The tenant may have a claim for breach of statutory duty and may have grounds to terminate the lease retroactively. Consult an attorney and consider offering a rent abatement or lease modification to resolve potential disputes. Going forward, ensure all new leases include proper radon disclosures.

Q4: If I remediate radon, do I need to test again?

A: Yes. Follow-up testing 7–30 days after mitigation is essential to confirm that the radon level has decreased below 4 pCi/L. If follow-up testing shows levels remain elevated, additional mitigation is required. Disclose follow-up results to tenants. This documentation protects you from future habitability claims.

Q5: What if a tenant refuses to sign the lease with radon warning language?

A: The tenant’s refusal does not waive your obligation to provide radon information. Document that you offered radon disclosure, explain it in writing, and note the tenant’s refusal. Some landlords use email confirmations or certified mail. However, refusal to sign may be grounds to decline to lease to that tenant. You have no obligation to lease to a tenant who refuses to acknowledge statutory disclosures.

Integrating Radon Compliance into Your Leasing Workflow

Self-managing landlords often juggle multiple compliance requirements. To simplify radon compliance:

• Create a radon disclosure template specific to each property. Include property address, test date (if tested), result (if tested), EPA action level reference, and signature block.
• Maintain a radon testing schedule. Test new properties before first occupancy. Re-test every 3–5 years or when major foundation work is done (cracks repaired, etc.).
• Store all test reports and disclosures digitally. Use cloud storage or your lease management system to ensure 3+ year retention and quick retrieval in case of tenant disputes or enforcement inquiries.
• Include radon questions in pre-lease tenant communications. Ask if the tenant has radon concerns or has experienced radon issues in prior residences. This opens dialogue and demonstrates landlord diligence.
• Standardize lease language. Use the same radon warning and remediation-cost-allocation language across all your properties (unless specific local rules differ).

Platforms like LeaseBase Lease Operations can centralize lease templates and ensure radon language is consistently included before tenants sign. This eliminates the risk of omitting radon warnings on individual leases.

Staying Current with Illinois Radon Law

Illinois radon law is not static. The Illinois Department of Public Health regularly updates guidance on radon testing standards and remediation. Recent trends include:

• EPA update (2023): The EPA lowered its recommendation to focus on radon levels above 2.7 pCi/L as a potential health concern, though 4 pCi/L remains the official action level. Illinois has not yet adopted the lower standard in statute, but courts may reference EPA guidance in habitability disputes. Monitor for legislative updates.
• Green remediation focus: Radon mitigation is increasingly viewed as a property improvement (not just a repair). Some state tax incentives exist for homeowners who install mitigation; landlords should investigate whether rent increases or tax deductions apply.
• Digital disclosure standards: Illinois is gradually moving toward digital lease delivery. Ensure your radon disclosure language works in digital formats and that e-signatures are properly captured.

Subscribe to Illinois Secretary of State updates and the Department of Public Health’s radon guidance page to stay informed of changes.

Documenting Radon Compliance: A Retention Strategy

Documentation is your defense. Retain:

• All radon test reports with certified professional’s name, license, test date, location, and result.
• Copies of radon disclosures provided to tenants (dated and signed or initialed by tenant).
• EPA guidance documents or Illinois Department of Public Health radon awareness materials provided to tenants.
• Signed leases with radon warning language.
• Email confirmations if disclosures were provided electronically.
• Mitigation contractor reports and follow-up test results (if remediation was performed).
• Tenant communications regarding radon concerns or requests for testing.

Retention period: 3 years minimum after lease termination (to cover most tenant claims and statute of limitations). Seven years is safer if you have capacity.

If a tenant or enforcement agency challenges your compliance, these documents prove you acted in good faith and followed Illinois law.

Key Takeaway: Radon Disclosure is Non-Negotiable

Radon is the second leading cause of lung cancer in the United States. Illinois takes radon disclosure seriously because the gas is invisible and dangerous. Unlike some landlord-tenant disputes that hinge on subjective judgments (e.g., “Is the unit habitable?”), radon violations are clear-cut: either you disclosed or you did not.

For self-managing landlords with 2–75 units, radon compliance is a baseline requirement, not an optional extra. The cost of disclosing and (if prudent) testing is trivial compared to the risk of lease terminations, rent abatement claims, statutory damages, attorney fees, and regulatory enforcement.

Action steps:

Why Surveillance Camera Rules Matter Now

You install a camera in the lobby to catch package thieves. Two weeks later, a tenant’s attorney sends a cease-and-desist letter claiming the camera violates her privacy rights. You check your lease—there’s no disclosure. Now you’re facing a §26-138 violation complaint filed with the NYC Department of Housing Preservation and Development (HPD), potential injunctive relief forcing removal, and a settlement demand for $15,000.

This scenario plays out dozens of times per month in New York City’s rental market. Unlike states with broad surveillance permission, New York has specific, enforceable rules about where cameras can go, what they can record, and how landlords must notify tenants. Ignorance doesn’t protect you—it’s an affirmative violation that tenants and their attorneys know how to exploit.

As a self-managing landlord, you don’t have a compliance officer. You need to know exactly where the law draws the line before you spend money on equipment that becomes a legal liability instead of a security asset.

What NYC Admin Code §26-138 Actually Says About Surveillance

NYC Admin Code §26-138, part of the Integrated Pest Management Law framework but also governing broader tenant privacy in common areas, establishes that landlords may install video surveillance in common areas of residential buildings only if:

• There is a documented, legitimate business purpose (security, crime prevention, package theft prevention)
• The camera does not record audio under any circumstances
• The camera is not placed in areas where tenants have a reasonable expectation of privacy
• Written notice is provided to all tenants before installation—not after
• The footage retention policy is reasonable and minimizes unnecessary data storage

Additionally, the New York City Human Rights Law (§8-102 et seq.) overlays protection against discrimination based on protected classes. A tenant could claim surveillance targeting her disability, national origin, or family status violates NYCHRL even if the technical camera placement is legal.

The Penal Law §250.00 (wiretapping) and federal Title III (18 U.S.C. §2511) create criminal exposure if audio is recorded without consent. This is not a civil fine—this is potential felony exposure.

Permitted Camera Locations in Common Areas

Hallways and Corridors

Hallways are permissible locations for video surveillance because tenants do not have a heightened privacy expectation walking through a shared space. However, the camera must:

• Be mounted in a location visible to tenants (not hidden)
• Be disclosed in the lease or a separate addendum signed before move-in or lease renewal
• Be positioned to avoid capturing doorways to individual apartments more than necessary for security
• Not record audio

Best practice: Position hallway cameras to cover the central corridor and stairwell access points, not aimed at specific apartment doors where tenants might reasonably undress before entering their unit.

Lobbies and Building Entrances

Front lobbies and entryway areas are generally acceptable locations, particularly for buildings with package theft, mail tampering, or unauthorized entry issues. Cameras must still comply with §26-138:

• Not record audio (no microphones)
• Be disclosed to tenants in writing before installation
• Not focus excessively on mail room or package delivery areas if tenants have privacy interest there

A building lobby camera is defensible because it serves the legitimate purpose of identifying intruders and monitoring common-area security. Courts in New York recognize this as a valid business purpose under §26-138(b)(1).

Stairwells and Fire Exits

Stairwell cameras are permissible with the same notice and audio-free requirements. They can help document unauthorized access and safety hazards. However, do not position a camera inside a stairwell landing where it captures someone entering from a specific apartment—that crosses into invasion of privacy.

Parking Areas and Loading Docks

If your building has a parking garage or loading area accessible to tenants, surveillance is permissible and often expected for theft prevention. The same §26-138 rules apply: no audio, written notice, legitimate purpose, and reasonable retention.

Strictly Prohibited Camera Locations

Bathrooms (Even Common Bathrooms)

Do not place cameras in any bathroom accessible to tenants, including shared bathrooms in common areas. This is a direct violation of Penal Law §250.00 and §26-138. Penalties include:

• Criminal misdemeanor charges (Class E felony for intentional recording)
• Civil liability up to $250,000 per violation under the NYC Human Rights Law
• Mandatory injunctive relief (camera removal) plus damages
• Potential sex offender registration in extreme cases

Changing Rooms, Locker Rooms, and Exercise Areas

If your building has a fitness room, yoga studio, or changing area, cameras are prohibited. Tenants have an explicit reasonable expectation of privacy in these spaces.

Apartments (Private Units)

You cannot install cameras inside a tenant’s apartment, period. This is a criminal trespass and invasion of privacy violation. Some landlords attempt to claim a “maintenance portal” camera—illegal. Tenants have absolute privacy in their unit.

Bedroom Windows or Doors (Partial Common Area Adjacency)

If a camera positioned in a hallway can see into a bedroom window or captures someone entering a bedroom, it’s prohibited. Courts in New York apply a “reasonable expectation of privacy” test. Even if technically in a common area, a camera aimed at a bedroom is a violation.

The Written Notice Requirement — Timing and Content

When Notice Must Happen

Under §26-138, notice must be provided before camera installation. This is not a post-installation notice scenario. If you already have cameras up and haven’t notified tenants, you are currently in violation.

For new tenants: Include the surveillance disclosure in the lease or as a separate signed addendum. For existing tenants: You must provide written notice at least 10 days before installation. Provide notice in writing, in person or via certified mail.

Courts have held that verbal notice or email (without confirmation of receipt) is insufficient. You need a paper trail showing each tenant received the notice.

What the Notice Must Include

Your written notice should state:

• The specific locations where cameras will be installed (e.g., “Lobby entrance, hallway third floor, stairwell between floors 2-3”)
• The business purpose (e.g., “to prevent package theft and monitor unauthorized entry”)
• The fact that audio is NOT recorded
• How long footage is retained (e.g., “30 days”)
• Who can access footage (e.g., “Management and licensed security personnel only”)
• The tenant’s right to request a copy of footage under FOIL (Freedom of Information Law) if applicable to their lease matter

Sample language: “Management has installed video surveillance in the building lobby and hallways for security and theft prevention purposes. These cameras record video only—no audio is recorded. Footage is retained for 30 days and accessed only by authorized management and security staff.”

Documenting Tenant Acknowledgment

Have tenants sign an acknowledgment that they received and understood the notice. Keep these signed acknowledgments in your tenant file. If a dispute arises later, you can prove you complied with §26-138’s notice requirement.

For month-to-month tenants, annual re-notification is prudent. For lease renewals, include the disclosure in the renewal addendum.

Audio Recording — Absolute Prohibition

New York is a two-party consent state for audio recording. This means all parties must consent to being recorded. Recording someone’s voice in a common area without their explicit consent is a violation of:

• Penal Law §250.00 (wiretapping/eavesdropping) — misdemeanor or felony depending on intent
• Federal Title III (18 U.S.C. §2511) — civil penalties up to $100,000 per violation, plus criminal exposure
• NYC Admin Code §26-138 (privacy protection)

Do not install cameras with built-in microphones or that record audio in any tenant-accessible area. Even if you never activate the audio, simply having the capability in a common area is problematic and invites tenant complaints.

If you purchase a camera system that includes audio capability, physically disable or remove the microphone before installation in a residential building. Document this action in your compliance records.

Consequence of audio recording: A tenant discovers your hallway camera has a microphone. She files a complaint with HPD and consults an attorney. Even if you never actually recorded audio, the presence of the capability gives her grounds to sue for invasion of privacy and demand camera removal plus damages. Many settlements exceed $20,000 in this scenario.

Retention Policies and Data Minimization

New York courts and regulatory guidance favor data minimization—keeping footage only as long as necessary for the stated business purpose. If your purpose is identifying package thieves, 30 days is reasonable. If your stated purpose is “general security,” keeping footage for 90 days is defensible. Keeping footage for 6 months or 1 year requires documented justification.

Create a Written Retention Policy

Document your retention schedule in writing:

“Surveillance footage in common areas is retained for 30 days from the date of recording. Footage older than 30 days is automatically deleted unless it is evidence of a crime or maintenance issue, in which case it is retained for 90 days pending resolution. Only authorized management staff may access footage. Tenants may request copies of footage involving their unit for lease-related disputes via written request to [your contact info].”

Include this policy in your tenant handbook or lease addendum. It demonstrates compliance with §26-138’s implicit requirement for reasonable, documented data practices.

If a tenant requests footage of a hallway incident involving her, you should have a process to provide it. If you cannot because it was deleted, your retention policy must justify the deletion (30-day standard = reasonable).

When Tenants Can Challenge Your Cameras

Non-Compliance with §26-138

A tenant can file a complaint with HPD if:

• You did not provide written notice before installation
• The camera records audio
• The camera is placed in an area where she has a reasonable expectation of privacy (e.g., directed at her bedroom window)
• No legitimate business purpose is documented

HPD can issue a violation notice to you. The penalty framework is not a published fine schedule—HPD determines violations on a case-by-case basis. However, documented HPD violations can trigger:

• Injunctive relief (court order to remove the camera)
• Civil penalties ranging from $500 to $5,000+ depending on severity and duration of violation
• Tenant’s right to break the lease without penalty due to landlord breach of §26-138

Human Rights Law Claims

If a tenant can demonstrate the surveillance targets her based on a protected class (race, national origin, disability, family status, etc.), she has a claim under NYC Human Rights Law §8-102. Penalties in these cases are substantial:

• Actual damages (her out-of-pocket harm)
• Consequential damages (emotional distress, moving costs)
• Punitive damages (up to $250,000 per violation in egregious cases)
• Attorney’s fees and costs

For example: You install a camera in the hallway outside a unit occupied by a single mother with a disability. She files a complaint alleging the camera was installed to monitor and discriminate against her. Even if your stated purpose was legitimate, the timing and placement fuel a plausible discrimination claim. Litigation costs and settlement demands become substantial.

Right to Withhold Rent

Under New York Real Property Law §223-b, a tenant may have the right to withhold rent if a landlord violates the warranty of habitability or violates tenant privacy rights under §26-138. If a tenant legitimately claims you violated surveillance rules, she can place rent in escrow pending resolution. While you can still pursue eviction for non-payment, the court will consider the landlord’s violation a defense.

Compliance Checklist for Surveillance Installation

Use this step-by-step checklist before installing any camera system:

Task	Compliance Requirement	Status
Determine business purpose	Document the specific reason for surveillance (theft prevention, unauthorized access, etc.)	☐
Identify permitted locations only	Cameras only in lobbies, hallways, stairwells, parking areas—never bathrooms, bedrooms, changing areas	☐
Verify no audio recording	Confirm cameras have no microphones; disable audio capability if built-in	☐
Draft written notice	Include locations, purpose, retention policy, no-audio statement, access controls	☐
Distribute notice to all tenants	Provide written notice at least 10 days before installation; certified mail or in-person	☐
Obtain signed acknowledgments	Have each tenant sign confirmation of receipt; keep in file	☐
Install cameras	Position to avoid private areas; use visible mounting	☐
Document retention schedule	Create written policy (30-day default recommended); retain in building file	☐
Update lease/house rules	Include surveillance disclosure in lease addendum or tenant handbook	☐
Establish access controls	Limit who can view footage; log all access; document in compliance file	☐
Annual review	Re-notify tenants annually; confirm cameras are functioning and compliant	☐

Real-World Scenarios: What Compliance Looks Like

Scenario 1: Lobby Camera for Package Theft

Situation: Your 20-unit building has had recurring package thefts. You want to install a camera in the lobby focused on the package shelf area.

Compliant approach:

• Document the business purpose: “Prevent mail and package theft” (dated memo in your file)
• Select a camera without audio; confirm with the vendor
• Position camera to cover the package area and lobby entry, but not directed at apartment doors or windows
• Draft and send written notice to all 20 tenants at least 10 days before installation. Certified mail is safest.
• Include: specific location (lobby, package area), purpose (theft prevention), no-audio statement, 30-day retention schedule
• Collect signed acknowledgments from each tenant
• Set up automatic footage deletion after 30 days
• Create a written access log: only you and your maintenance manager can view footage
• Include the surveillance disclosure in all future lease renewals

Non-compliant approach (and why it fails): You install a camera without notice. A tenant sees it, files a complaint with HPD. HPD issues a violation for lack of prior notice under §26-138. You’re ordered to remove it. Cost: removal, HPD fine ($500–$2,000), and damaged tenant relationship.

Scenario 2: Hallway Cameras on Upper Floors

Situation: You have a 50-unit building with unauthorized entry and break-ins occurring on the 5th and 6th floors. You want to install hallway cameras.

Compliant approach:

• Document the business purpose: “Prevent unauthorized entry and identify break-in suspects” (dated memo)
• Position cameras to cover the hallway corridor and stairwell entrance, NOT aimed at individual apartment doors
• Confirm cameras are audio-free
• Provide written notice to all tenants (not just 5th and 6th floor) because they all use common areas: “Surveillance cameras have been installed in the hallways on floors 5 and 6 to prevent unauthorized entry and identify intruders. Cameras record video only; no audio is recorded. Footage is retained for 30 days.”
• Set retention to 30 days and automate deletion
• Document who can access footage (you, security company, police if requested with warrant)

Pitfall to avoid: Do not angle the camera to capture someone entering/exiting a specific apartment. This invades privacy of that tenant even though the camera is technically in a common area. Frame the shot to capture the broader hallway.

Scenario 3: Package Room with Tenant Access

Situation: Your building has a package room managed by tenants. You want to install a camera to track who takes what.

Compliant approach:

• Camera is permissible if positioned to view the shelving and entry only
• Documented purpose: “Prevent package misdelivery and theft”
• Written notice to all tenants; no-audio confirmation
• Retention: 30 days (reasonable for package-related disputes)
• Access: only management; tenants can request footage if they claim a package was wrongly taken

Non-compliant approach: You angle the camera at a specific tenant’s packages because you suspect her of taking others’ deliveries. This appears discriminatory (targeting one tenant) and violates her reasonable expectation of privacy in a shared-access space. She files a Human Rights Law complaint. Cost: $15,000–$50,000 settlement.

Compliance Tools and Documentation for Self-Managers

Managing compliance manually with spreadsheets and email folders creates blind spots. Use the following tools to document and track your surveillance compliance:

• Compliance checklist template — Save in your building file; update annually
• Tenant notice template — Customize with your building address and camera locations; send certified mail
• Signed acknowledgment forms — Keep copies in each tenant’s file and in a master compliance binder
• Camera access log — Record every instance footage is viewed, by whom, and why
• Retention schedule reminder — Set a calendar alert to verify footage deletion is happening on schedule
• Vendor documentation — Keep camera specifications and proof that audio is disabled

LeaseBase’s compliance engine tracks statutory requirements by jurisdiction, including New York surveillance rules. You receive alerts when notice is due or when your retention policy is about to create a compliance gap. For multi-property owners, this prevents one building’s violation from going unnoticed while you manage others.

Changes and Updates in 2024-2026

As of July 2026, New York has not substantially amended §26-138 regarding residential surveillance, but enforcement has tightened. HPD and the NYC Commission on Human Rights have increased focus on surveillance complaints filed by tenants, particularly in buildings serving vulnerable populations (seniors, disabled tenants, immigrant communities).

The trend in New York case law favors tenant privacy. Courts are interpreting “reasonable expectation of privacy” broadly, especially in hallways where tenants transition between public and private spaces. A camera positioned to see into an apartment from a hallway, or capturing someone undressing before entering a unit, has been found to violate privacy even with notice.

Recommendation: If you have existing surveillance, audit it now. Ensure all cameras comply with the 2026 interpretation of §26-138—position conservatively, retain footage minimally, and confirm tenants received proper notice.

Frequently Asked Questions

Q: Do I need a lawyer to install a surveillance camera in my building’s lobby?

A: You do not need a lawyer if you follow §26-138 strictly: document your business purpose, confirm the camera has no audio, provide written notice to all tenants at least 10 days before installation, collect signed acknowledgments, and set a 30-day retention schedule. However, if your building is large (50+ units) or serves a vulnerable tenant population, a brief legal review of your notice language is prudent. The cost of a lawyer reviewing your notice ($300–$500) is far less than the cost of defending an HPD violation or tenant lawsuit ($5,000–$50,000).

Q: What if I already have cameras installed and haven’t notified tenants?

A: You are currently in violation of §26-138. Take immediate action: (1) Notify all tenants in writing of the cameras’ locations and purpose. (2) Include a statement that you are providing retroactive notice. (3) Offer tenants a reasonable grace period (e.g., 10 days) to file complaints or concerns. (4) Document that you have corrected the violation. (5) Going forward, obtain signed acknowledgments from all new tenants. While you cannot undo the violation, documenting your immediate correction limits HPD’s ability to impose further penalties and may help if a tenant sues.

Q: Can I install a hidden camera in a hallway as long as it’s audio-free?

A: No. §26-138 requires transparency. Tenants must be able to see the camera (or at minimum, must have been notified of its existence and location). A hidden camera, even if audio-free, violates tenant privacy expectations and gives HPD grounds for a violation. Additionally, hidden surveillance may trigger criminal charges under Penal Law §250 (unlawful surveillance) depending on intent.

Q: Can I use footage from a hallway camera to evict a tenant for violation of house rules?

A: Yes, but only if the footage directly shows a violation (e.g., a tenant bringing an unpermitted pet into the building, or a guest violating the guest policy). However, the footage was taken in compliance with §26-138 (proper notice, no audio, legitimate purpose). Use it judiciously. Relying on footage to pursue strict enforcement can escalate tenant relationships and invite counter-complaints about privacy violations.

Q: Does the camera need to be visible, or can it be discreet/small?

A: The camera doesn’t need to be a large, obvious dome camera, but it must be discernible to a reasonable person in the hallway or lobby. A discreet camera mounted in a corner is acceptable as long as tenants were notified of its presence and location. Hidden cameras disguised as smoke detectors or sprinklers are not permitted.

Summary: Surveillance Compliance Roadmap for NY Landlords

New York’s approach to residential surveillance prioritizes tenant privacy over landlord convenience. §26-138 is enforceable, and violations carry real penalties: HPD citations, injunctive relief, tenant rights to withhold rent, and civil liability under the Human Rights Law.

The good news: Compliance is achievable with a straightforward process. Document your business purpose, choose permitted locations, eliminate audio, notify tenants in writing, and set a reasonable retention schedule. These steps take a few hours per building and create a defensible record if a tenant or regulator questions your cameras.

For self-managing landlords, the challenge is tracking compliance across multiple tenants and lease cycles. Spreadsheets fail. A compliance platform that flags when notice is due, when retention needs to be enforced, and when lease renewals require updated disclosures eliminates guesswork.

LeaseBase’s platform includes compliance tracking for state-specific requirements like New York surveillance rules. You receive reminders to re-notify tenants, verify camera functionality, and document your access controls. For landlords managing 2–75 units, this centralization prevents the §26-138 violations that cost thousands in fines and tenant disputes.

Start by auditing your current surveillance setup against the checklist above. If you find gaps, correct them immediately. The cost of proactive compliance is minimal; the cost of a tenant lawsuit over privacy violations is substantial.
