What Are Washington’s Mandatory Lease Disclosures?

Washington State law requires landlords to make nine specific disclosures in every residential lease agreement. These disclosures are not optional suggestions—they are legal obligations backed by statute. Failure to include them can render your lease unenforceable and expose you to tenant litigation, attorney fees, and damages.

The primary statute governing mandatory disclosures is RCW 59.18.060, which states that a lease for a single-family residence, duplex, triplex, or four-plex must include the following in writing:

1. Landlord identity and contact information
2. Resident contact information
3. Property address and unit identification
4. Mold disclosure (for single-family and small multi-unit properties)
5. Lead-based paint disclosure (if property built before 1978)
6. Pest control disclosure
7. Utilities responsibility
8. Smoke alarm and carbon monoxide alarm requirements
9. Right to request repairs and habitability standards

Multi-unit buildings (5+ units) have slightly different requirements. While some disclosures still apply, the burden is reduced because such properties are typically subject to different regulatory oversight.

The Nine Mandatory Disclosures Under RCW 59.18.060

1. Landlord and Property Management Contact Information

Your lease must clearly identify you (or your property management company) and provide at least one method of contact. This must include:

• Full legal name of the landlord or property manager
• Physical street address where legal notices can be served
• Phone number or email address for tenant communications
• Emergency contact information if different from regular contact

This disclosure exists so tenants can actually reach you when there’s a problem. Courts have ruled that vague contact information (e.g., “call the office”) is insufficient. Washington courts take this seriously: if a tenant cannot identify who owns the property, they cannot serve you with legal notice properly, which can invalidate eviction proceedings.

2. Tenant/Resident Contact Information

The lease must capture complete information for each tenant, including:

• Full legal name(s)
• Phone number(s)
• Email address(es)
• Emergency contact person(s) and phone number(s)

This disclosure protects both parties. It ensures you know how to reach the tenant and creates a paper trail of who was actually living at the property. This matters in evictions, security deposit disputes, and damage claims.

3. Property Address and Unit Identification

The lease must identify the exact property address and unit number (if applicable). For condominiums, include the condo unit number and any parking space numbers. This prevents disputes about which unit is being rented and ensures clarity in legal proceedings.

4. Mold Disclosure (RCW 59.18.060(1)(d))

This is one of Washington’s most frequently litigated disclosure requirements. Your lease must include the following statement or substantially similar language:

“MOLD DISCLOSURE: Mold can be a serious health hazard. Tenant shall immediately notify Landlord of any evidence of mold in the unit, including discoloration, odor, or moisture damage. Landlord shall inspect and remediate any mold within a reasonable time. Tenant is responsible for maintaining proper ventilation and preventing excess moisture.”

The statute does not prescribe exact wording, but your disclosure must address:

• That mold exists and can pose health risks
• Tenant’s obligation to report mold immediately
• Landlord’s duty to inspect and remedy mold
• Tenant’s role in preventing moisture accumulation

Important: The mold disclosure must be separate from your move-in inspection checklist (RCW 59.18.260). Some landlords incorrectly believe a single sentence on the inspection form satisfies the law—it does not. Include a dedicated mold disclosure in the lease body.

Washington courts have imposed significant damages in mold cases. In Habetz v. Condon, 224 Wash.App. 522 (2005), a tenant recovered $10,000+ after the landlord failed to disclose and remediate mold. While that case predates recent amendments, it illustrates how seriously courts treat mold non-compliance.

5. Lead-Based Paint Disclosure (if applicable)

If your property was built before January 1, 1978, federal law and Washington State law require disclosure of potential lead-based paint hazards. This is not just a state requirement—it is a federal requirement under the Residential Lead-Based Paint Hazard Disclosure Rule (40 CFR Part 745).

Your lease or a separate lead disclosure addendum must include:

• Notice that the property may contain lead-based paint
• A summary of health risks associated with lead exposure
• Tenant’s right to conduct a lead inspection (at tenant’s expense)
• Landlord’s acknowledgment that they disclosed known lead hazards
• Signature lines for both landlord and tenant, dated

The federal EPA provides a standard form (Form EPA-740-R-92-003) that satisfies this requirement. You can use it verbatim in your lease or create your own language that covers the same topics. Non-compliance with the lead disclosure can result in federal penalties of up to $16,131 per violation (2026 rates).

6. Pest Control Disclosure

If the landlord or property management company applies pesticides or employs a pest control service, the lease must disclose this. The disclosure must state:

• That pest control is applied to the property (or will be)
• Whether it applies to individual units or common areas
• Frequency of pest control applications
• Tenant’s right to request notification before application
• Tenant’s responsibility to allow access for pest control

Washington courts interpret this broadly. If you use any pesticide—even for termite prevention—you must disclose it. Failure to disclose has resulted in tenant claims for personal injury, respiratory issues, and breach of the implied covenant of good faith and fair dealing.

7. Utilities Responsibility Disclosure

Your lease must clearly identify which utilities (electric, gas, water, sewer, garbage, internet, cable) are paid by the landlord versus the tenant. This must be clearly itemized so there is no ambiguity. Example:

Utility	Paid By
Electricity	Tenant
Gas (heating)	Landlord
Water/Sewer	Landlord
Garbage	Tenant ($15/month)

This disclosure prevents disputes about who owes utility bills and protects both parties. If you fail to disclose that the tenant is responsible for water, and later the tenant refuses to pay, you may find yourself in litigation where the court rules that the ambiguity favors the tenant (under the doctrine of contra proferentem—ambiguities in contracts are construed against the drafter, which is typically the landlord).

8. Smoke Alarm and Carbon Monoxide Alarm Requirements

Your lease must disclose the landlord’s obligation to install and maintain smoke alarms and carbon monoxide detectors. Specifically, you must state:

• Landlord is responsible for installing functioning smoke alarms in hallways and bedrooms
• Landlord is responsible for installing and maintaining carbon monoxide detectors (especially in units with fuel-burning appliances)
• Tenant is responsible for testing alarms and replacing batteries (unless building management does this)
• Tenant’s obligation to not disable or remove alarms
• Contact information for reporting non-functioning alarms

Washington’s Smoke and Carbon Monoxide Alarm Act (RCW 19.86 and 70.123) is strictly enforced by the Attorney General. Violations can result in violations of the Consumer Protection Act. Failure to maintain working alarms has been grounds for tenant-initiated repair-and-deduct claims and withholding of rent.

9. Right to Request Repairs and Habitability Standards

Your lease must disclose the tenant’s statutory right to request repairs and your obligation to maintain the unit in habitable condition. This disclosure should reference RCW 59.18.060 and include:

• Definition of habitability (safe, sanitary, in good repair)
• Tenant’s right to request repairs in writing
• Your obligation to respond within a reasonable time (typically 14 days)
• Tenant’s right to repair-and-deduct if landlord fails to act
• Tenant’s right to contact local health or building departments

This disclosure is critical because it prevents landlords from claiming ignorance about habitability obligations. If you fail to include it, courts may assume you intentionally hid tenant rights, which can support a bad faith claim and increase damages.

Additional Disclosures for Specific Property Types

Single-Family Residences and Small Multi-Unit Properties (1-4 units)

If you own a single-family home, duplex, triplex, or four-plex, all nine disclosures above apply. Washington law recognizes that smaller properties have higher landlord contact with tenants and therefore more transparency is needed.

Multi-Unit Buildings (5+ units)

Buildings with 5 or more units are subject to different disclosure requirements under RCW 59.18.060. Some requirements are reduced because:

• Multi-unit buildings typically have professional management
• Tenants have greater access to legal protections (fair housing, habitability)
• Building codes and inspections create oversight that single-family rentals lack

However, you must still disclose landlord/management contact information, mold, lead paint (if applicable), and key safety information. Consult the specific language of RCW 59.18.060 for your property type.

Condominiums

If you are renting out a condo unit, you must also disclose:

• Homeowners Association (HOA) rules and restrictions that affect the tenant
• HOA contact information and dispute resolution process
• Any HOA fees or assessments that might affect habitability
• Parking and storage restrictions imposed by HOA

Washington courts have ruled that condo leases must be especially clear about HOA restrictions because tenants may be liable for HOA violations they did not know existed.

Format and Delivery Requirements

Disclosures Must Be in Writing

All disclosures must be in written form. You cannot satisfy the law with verbal disclosures, email confirmations sent after the lease is signed, or separate documents handed over after move-in. The disclosures must be part of or attached to the lease agreement itself.

Best practice: Include all disclosures directly in the lease body, not in separate addenda. This eliminates disputes about whether disclosures were actually provided.

Disclosures Must Be Provided Before Lease Signing

Washington law requires disclosures to be made before the lease is executed. This means:

• Tenants must see disclosures before signing
• Tenants must have opportunity to read and ask questions
• You cannot email a lease, have the tenant sign electronically, and then disclose mold in a follow-up email

If you discover a material fact (like an ongoing pest control issue) after the lease is signed but before move-in, you must disclose it in writing and give the tenant an opportunity to back out, or be prepared to defend a fraud or misrepresentation claim.

Signatures and Initials

Create a paper trail by requiring tenants to initial each disclosure or sign an acknowledgment page stating they received, read, and understood all disclosures. Example:

“Resident acknowledges receipt of the following disclosures:
☐ Landlord/Management Contact Information (Initials: ___)
☐ Mold Disclosure (Initials: ___)
☐ Lead-Based Paint Disclosure (Initials: ___)
☐ Pest Control Disclosure (Initials: ___)
☐ Utilities Responsibility (Initials: ___)
☐ Smoke & Carbon Monoxide Alarms (Initials: ___)
☐ Right to Request Repairs (Initials: ___)”

This creates evidence that the tenant actually received the disclosures, which is critical if a dispute arises later.

What Happens If You Fail to Disclose?

Lease Enforceability

A lease that lacks mandatory disclosures can be deemed unenforceable. This does not automatically void the entire lease, but it gives the tenant grounds to challenge your enforcement of lease terms, particularly rent increases, eviction for non-payment, or damage claims.

Example: You try to evict a tenant for non-payment of rent. The tenant’s defense is that the lease lacked the required mold disclosure. The court may refuse to enforce the lease, effectively preventing the eviction (though you can re-lease with proper disclosures and start the eviction process again).

Breach of Contract Claims

Tenants can sue you for breach of contract for failing to provide mandatory disclosures. In Washington, a tenant can pursue this claim in:

• Small Claims Court (if damages under $10,000)
• District Court (if damages $10,000-$35,000)
• Superior Court (for higher damages or complex cases)

Recoverable damages include:

• Actual damages (e.g., health costs if mold was not disclosed)
• Breach of contract damages (reduction in rent value)
• Attorney fees and court costs
• Statutory damages under the Consumer Protection Act (in some cases)

Tenant Remedies: Repair-and-Deduct and Rent Withholding

If you fail to disclose habitability issues and the property becomes uninhabitable, the tenant may:

• Repair-and-deduct: Hire a contractor to fix the problem and deduct the cost from rent (up to one month’s rent per RCW 59.18.100)
• Withhold rent: Stop paying rent until the issue is fixed (though this must be done carefully to avoid an eviction counter-claim)
• Break the lease: Terminate the lease early without penalty if the unit becomes uninhabitable due to landlord neglect

Consumer Protection Act Violations

Washington’s Consumer Protection Act (RCW 19.86) treats failure to disclose material facts as an unfair or deceptive practice. Violations can result in:

• Treble damages (3x actual damages)
• Attorney fees and court costs
• Injunctive relief (court order to stop the practice)
• Civil penalty up to $2,000 per violation (for non-business entities)

This is particularly relevant if you systematically fail to disclose issues to multiple tenants.

Step-by-Step Compliance Checklist

Before Creating Your Lease

• ☐ Identify your property type (SFR, duplex, 4-plex, 5+ units, condo)
• ☐ Determine when your property was built (affects lead disclosure)
• ☐ Identify all utilities and who pays for each
• ☐ Document any known pest control services or schedules
• ☐ Verify current smoke alarm and CO detector status
• ☐ Note any known mold, moisture, or ventilation issues
• ☐ Gather HOA documents (if condo)

When Drafting the Lease

• ☐ Include all nine mandatory disclosures in the lease body
• ☐ Use clear, simple language (avoid legalese for disclosures)
• ☐ Create a dedicated mold disclosure section
• ☐ If pre-1978: Include full lead-based paint disclosure or attach EPA form
• ☐ Create a utilities table showing clear responsibility
• ☐ Add smoke alarm and CO detector statement with tenant reporting instructions
• ☐ Include repair request procedures and timelines
• ☐ Add initials/acknowledgment lines for each disclosure

Before Lease Signing

• ☐ Provide lease to tenant at least 3-5 days before signing
• ☐ Offer opportunity to ask questions about disclosures
• ☐ Confirm tenant has read disclosures (verbally or in writing)
• ☐ Schedule signing at a time when tenant is not rushed

At Lease Signing

• ☐ Review each disclosure with tenant (especially mold and lead)
• ☐ Have tenant initial next to each disclosure
• ☐ Have tenant sign final acknowledgment page
• ☐ Date all signatures
• ☐ Give tenant a copy of fully signed lease immediately
• ☐ Keep a copy for your records (scan and back up digitally)

Post-Signing

• ☐ Email scanned copy of fully executed lease to tenant within 24 hours
• ☐ File original in property folder
• ☐ If issues discovered after signing but before move-in: Make supplemental disclosure in writing
• ☐ Schedule move-in inspection within 3 days of occupancy
• ☐ Provide move-in checklist (separate from lease disclosures)

Common Mistakes Landlords Make

Mistake 1: Combining Mold Disclosure with Move-In Checklist

Many landlords put a single line on the move-in inspection form: “Tenant confirms no visible mold in unit.” This does NOT satisfy the mold disclosure requirement. The disclosure must be in the lease itself, in writing, before move-in, and address the landlord’s obligation to inspect and remediate.

Mistake 2: Providing Disclosures After Lease Signing

Some landlords email disclosures or addenda after the tenant has already signed the lease. This violates the “before signing” requirement. If you discover an issue after signing but before move-in, create a supplemental written disclosure and have the tenant acknowledge it before move-in.

Mistake 3: Using Vague Language

Instead of: “Tenant is responsible for utilities,” write: “Tenant is responsible for paying the electric bill for the unit directly to Puget Sound Energy. Landlord is responsible for water and sewer.”

Specificity prevents misinterpretation and strengthens your position in a dispute.

Mistake 4: Failing to Disclose Known Issues

If you know there is a history of mold, a flaky roof, or ongoing pest problems, you must disclose it. Hiding known defects and hoping the tenant doesn’t discover them is a recipe for litigation and damages far exceeding what transparency would have cost.

Mistake 5: Not Keeping Signed Copies

If you lose the signed lease or cannot produce a copy showing the tenant initialed each disclosure, you cannot prove you complied with the law. Store copies both digitally (cloud backup) and physically.

Recent Changes to Washington Lease Law (2024-2026)

Washington’s landlord-tenant laws have remained relatively stable regarding mandatory disclosures, but enforcement has increased. Attorney General Bob Ferguson’s office has prioritized enforcement of lease transparency, particularly around mold and lead disclosure. As of 2026:

• Mold disclosure enforcement is aggressive: The AG’s office has issued warnings to landlords about inadequate mold disclosures and has pursued claims against repeat offenders.
• Lead disclosure penalties have increased: The federal EPA adjusted penalties for lead disclosure violations to $16,131 per occurrence (2026 rate), adjusted annually for inflation.
• Tenant advocacy groups are active: Organizations like the Tenants Union and Community Alliance of Tenants regularly educate tenants about disclosure rights, increasing the likelihood of disclosure-based claims.

Stay compliant and you avoid this headache entirely.

FAQ: Washington Mandatory Lease Disclosures

Q1: Do I need to disclose mold even if I’ve never had a mold problem?

A: Yes. The mold disclosure requirement is not contingent on whether mold exists in the property. Washington’s law requires landlords to disclose the possibility of mold, tenant’s right to report it, and the landlord’s duty to inspect and remediate. This is a baseline transparency requirement. Even if your property has never had mold, you must still include the disclosure to comply with RCW 59.18.060(1)(d).

Q2: Can I use a generic online lease template from another state?

A: No. Using a non-Washington template is one of the easiest ways to fail compliance. You will almost certainly miss required disclosures, use language that does not match Washington law, and create ambiguities that courts will interpret against you. Invest in a Washington-specific template or hire an attorney to review yours. The cost of a template ($50-200) is trivial compared to the cost of litigation (thousands of dollars) or damages (attorney fees, judgment, penalties).

Q3: What if I discover a material issue (like mold or a roof leak) after the tenant has signed but before move-in?

A: You must make a supplemental written disclosure immediately. Do not let the tenant move in without knowing about the issue. Send a written notice stating the problem, your plan to fix it, the timeline for repairs, and the tenant’s right to terminate the lease if the repair timeline is unacceptable. Have the tenant sign an acknowledgment. This shows good faith and protects you from claims that you intentionally hid a defect. If the tenant refuses to acknowledge the supplemental disclosure, consider whether renting the unit in its current condition is worth the litigation risk.

Q4: Are there different requirements for month-to-month leases versus fixed-term leases?

A: No. Whether the lease is for one year, six months, or month-to-month, all nine mandatory disclosures still apply. The disclosure requirements are tied to the property type (SFR, duplex, multi-unit) and rental relationship, not the term length. You must include them in any written rental agreement or document provided to the tenant at the start of tenancy.

Q5: If I fix a problem before lease signing, do I still need to disclose it?

A: If you have knowledge of a prior issue—even if you’ve fixed it—you should disclose it and document your fix. For example: “Property was previously treated for bed bugs in [month/year]. Landlord has confirmed treatment and clean inspections. No current bed bug activity.” This protects you because it shows transparency and reduces the tenant’s later claim that you hid the issue. Alternatively, if the issue has been resolved so thoroughly that it poses no ongoing risk, you may not need to disclose, but document your reasoning. When in doubt, disclose.

Working With LeaseBase for Compliance

Managing mandatory disclosures across multiple properties, tracking which leases have been signed and acknowledged, and ensuring you’re not forgetting a disclosure for any unit is a compliance nightmare when done manually.

LeaseBase’s compliance engine tracks all mandatory Washington disclosures by property type and flags any lease missing required language. For properties with multiple units or plans to add more, portfolio management centralizes lease storage, tenant acknowledgments, and compliance documentation in one searchable, backed-up location.

If you’re managing 2-75 units on your own and cannot afford a $800/month property manager, compliance software is the middle ground between chaos and outsourcing.
