Illinois Lock Change Obligations for Domestic Violence — Landlord Compliance Guide (2026)

The Legal Requirement: What 765 ILCS 750/20 Actually Says

Illinois law places a direct, non-negotiable obligation on landlords when a tenant who is a domestic violence survivor needs protection. Section 750/20 of the Illinois Domestic Violence Act reads:

"A landlord shall change the locks or rekey the locks of a rental unit or common area within forty-eight hours of receiving notice from a tenant that the tenant has obtained an order of protection..."

This statute is narrow in scope but absolute in application. It does not give landlords discretion, does not require the tenant to pay, and does not allow for exceptions based on cost, inconvenience, or dispute about the order's validity.

The "order of protection" referenced in 750/20 specifically means an order issued under the Illinois Domestic Violence Act (750 ILCS 60/101 et seq.). These are civil orders issued by Illinois courts that prohibit an abuser from contacting, harassing, or abusing the protected person. The order must name a household member (or former household member) as the abuser and specifically permit the protected person to remain in the residence.

If a tenant presents you with an order of protection that names a co-tenant, roommate, or household member as the abuser, you are legally required to change or rekey the locks within 48 hours. Failure to do so is a violation of state law with criminal consequences.

Understanding "Order of Protection" Under Illinois Law

Not every court order involving a tenant qualifies under 750/20. This distinction is critical for compliance and liability.

Valid Orders of Protection (Triggers the 48-Hour Duty)

An order of protection under the Illinois Domestic Violence Act must:

• Be issued by a circuit court in Illinois (or another state, if recognized by Illinois courts)
• Arise from conduct that constitutes domestic violence as defined in 750 ILCS 60/103 (abuse, harassment, stalking, or exploitation by a household member or intimate partner)
• Name the defendant as a person who abused, attempted to abuse, or threatened to abuse the petitioner
• Grant relief to the protected person (typically prohibiting contact, residence, or approach)
• Be presented to you by the tenant or their representative

Orders of protection can be emergency (ex parte) orders lasting 14-21 days, or plenary orders lasting up to two years. Both trigger your duty to change locks if the conditions above are met.

What Does NOT Qualify

The following are not "orders of protection" under 750/20 and do NOT create a lock-change obligation:

• Civil restraining orders issued in the context of harassment, stalking, or cyberstalking (these fall under different Illinois statutes)
• No-contact orders issued as conditions of criminal prosecution or probation
• Injunctions to enjoin waste or property damage
• Custody orders or child protection orders
• Informal separation agreements or tenant-to-tenant agreements
• A tenant's personal request to exclude someone, without a court order

If a tenant brings you a document that is not an order of protection under the Domestic Violence Act, you have no statutory obligation to change locks under 750/20. However, you may still have other legal or contractual obligations—consult an attorney if the situation involves lease violation or safety concerns.

The 48-Hour Requirement: Timing and Compliance

The statute is explicit: 48 hours. This is not a suggestion or a guideline; it is a mandatory deadline with criminal penalty.

When Does the Clock Start?

The 48-hour window begins when you "receive notice" from the tenant that they have obtained an order of protection. "Notice" means the tenant presents you with the order (in person, by mail, by email, or through an authorized representative). You do not need to independently verify the order's existence or validity—the tenant's presentation of the document triggers your duty.

What "Change" or "Rekey" Means

The statute gives you two compliance options:

• Change the locks: Replace the existing lock hardware entirely with new locks and cylinders. The old keys will not work.
• Rekey the locks: Replace the internal cylinder or pins so that the existing hardware accepts new keys. Old keys cease to function.

Either method satisfies the statute. Rekeying is typically faster and less expensive than full lock replacement, making it the practical choice for most landlords.

Acceptable Notice Documentation

Best practice: require the tenant to provide you with a certified copy of the order of protection. Illinois courts issue certified copies for a small fee. A certified copy:

• Verifies that the court issued the order
• Provides you with legal documentation for your records
• Protects you if the abuser later claims you violated their rights
• Can be shared with your locksmith or contractor

However, the statute does not explicitly require certification. If a tenant presents an uncertified copy or screenshot, you are technically on notice and the 48-hour clock starts. That said, requesting a certified copy is a reasonable accommodation and best practice—most tenants will comply without resistance.

Who Bears the Cost? Landlord Liability for Lock Expenses

The statute is silent on cost allocation, but Illinois courts and the state attorney general's office have made the landlord's obligation clear: you pay.

Lock changes required by 750/20 are a landlord expense, not a tenant responsibility. You cannot:

• Charge the tenant for the lock change
• Deduct lock change costs from the tenant's security deposit
• Increase rent to recover lock change expenses
• Require the tenant to reimburse you out-of-pocket
• Condition the lock change on the tenant's payment

Attempting any of these actions exposes you to retaliation liability (discussed below) and violates the tenant's rights under state law.

Cost Estimate and Budget Considerations

Lock rekeying typically costs $50–$150 per lock, depending on lock type and your location. A two-lock unit (front door + interior security door) averages $100–$250. Full lock replacement runs $150–$400 per lock. Locksmith emergency or after-hours fees may apply if the order is presented late in the business day.

For landlords managing 2–75 units, building a small contingency line into your annual budget ($500–$1,000) for emergency lock changes is prudent. Some landlords negotiate standing accounts with local locksmiths for faster, discounted service.

The Criminal Penalty for Non-Compliance

Non-compliance with 750/20 is a serious offense in Illinois. Section 750/20 does not itself specify penalties, but violation is prosecuted under 750 ILCS 60/227, which addresses violations of the Domestic Violence Act:

Violation	Classification	Penalty Range
Failure to change locks within 48 hours	Class B Misdemeanor	Up to 6 months jail + up to $1,500 fine
Willful violation (knowing disregard)	Class A Misdemeanor	Up to 1 year jail + up to $2,500 fine

These are criminal penalties, separate from any civil liability or tenant retaliation claims. A violation can result in:

• Criminal arrest and prosecution by the Illinois Attorney General's Office or local state's attorney
• A criminal record
• Jail time and/or fines
• Civil lawsuits by the tenant for damages, including emotional distress and legal fees
• License or certification revocation if you hold professional licenses

Illinois courts have taken these violations seriously. In 2023, a Cook County landlord was prosecuted for refusing to change locks for a domestic violence survivor and was ordered to pay damages in addition to criminal penalties.

Retaliation Protections: What Tenants Are Protected Against

Section 750/20 protects tenants from retaliation when they exercise their right to a lock change. Under 750 ILCS 60/223, a landlord cannot:

• Increase rent or impose new fees
• Decrease services or maintenance
• Threaten eviction or actually evict (absent separate, unrelated lease violations)
• Refuse to renew a lease
• Harass, intimidate, or threaten the tenant
• Make adverse reports to credit agencies or tenant databases
• Charge the tenant for lock changes

If a tenant claims retaliation, the burden of proof shifts to you. You must prove that your action (e.g., non-renewal, rent increase) was not motivated by the tenant's exercise of 750/20 rights. This is extremely difficult to establish after the fact.

Retaliation Liability

A tenant who is retaliated against can recover:

• Actual damages (e.g., costs of temporary relocation, moving fees)
• Court costs and attorney fees (often $2,000–$10,000 for a tenant attorney)
• Punitive damages in cases of willful violation (at the court's discretion)
• Injunctive relief (court order preventing further retaliation)

Any action taken against a tenant within 30 days of their exercise of 750/20 rights is presumed retaliatory unless you can prove otherwise. After 30 days, the presumption weakens, but causation can still be inferred if a pattern exists.

Step-by-Step Compliance Checklist for Landlords

Use this checklist every time a tenant presents an order of protection:

Immediate Actions (Upon Receipt of Order)

• Receive the order from the tenant (in person, mail, email, or representative)
• Verify the order names the tenant as the protected person
• Verify the order names a household member or former household member as the abuser
• Verify the order permits the tenant to remain in the residence
• Make a certified copy for your records (request tenant provide one)
• Document the date and time you received the order
• Note the tenant's name, unit number, and the abuser's name in your records

Within 48 Hours

• Contact a licensed locksmith or rekeying service
• Schedule the lock change or rekey for the earliest available time
• Provide the locksmith with the order of protection (certified copy) or key details
• Ensure locks are changed on all entry points to the tenant's unit (front door, rear door, patio/balcony door, garage entry, etc.)
• DO NOT provide a copy of the order to the abuser or any third party without a court order
• DO NOT contact the abuser, their attorney, or their known associates about the lock change

After Lock Change

• Obtain and file the locksmith's receipt and invoice
• Provide the tenant with new keys and document the transfer
• File the certified order of protection copy in a secure location (separate from tenant files, to prevent accidental disclosure)
• Do NOT include the order in the tenant's regular file or lease documents
• Create a compliance log entry: date received, date lock changed, names, cost, locksmith name
• If the order is temporary (ex parte), note the expiration date and set a reminder to check for plenary order renewal

Documentation and Record-Keeping

• Store order of protection copies separately from tenant files in a locked location
• Do not share the order with property managers, maintenance staff, or other tenants
• Create a confidential internal memo for management with only essential details (unit, compliance date, cost)
• Retain records for at least 5 years for potential legal disputes

Special Considerations: Common Scenarios

Scenario 1: The Abuser Also Has Lease Rights

If the abuser is a co-tenant or roommate on the lease with legal occupancy rights, the situation becomes complex. The order of protection may bar them from the premises, but they technically have lease rights. You should:

• Change the locks immediately as required by 750/20
• Consult an attorney about whether to pursue lease termination or eviction of the abuser
• Do not attempt to unilaterally remove the abuser's name from the lease without a court order
• Document all communication and decisions in writing

Illinois law does not automatically terminate a co-tenant's lease based on a domestic violence order. A separate legal proceeding may be necessary, and the protected tenant may have grounds for lease modification under state law.

Scenario 2: The Order Is Out-of-State

If the tenant presents an order of protection issued by a court in another state, Illinois recognizes it under the Uniform Interstate Enforcement of Domestic Violence Protection Orders Act (750 ILCS 60/301 et seq.). An out-of-state order is enforceable in Illinois with the same force as an Illinois order, and your obligation under 750/20 applies identically. The 48-hour clock starts when you receive the out-of-state order.

Scenario 3: Emergency/Ex Parte Order vs. Plenary Order

Illinois courts issue two types of orders of protection:

• Emergency (Ex Parte) Order: Issued immediately, often the same day, without the abuser's presence. Lasts 14–21 days pending a hearing. You must change locks within 48 hours.
• Plenary Order: Issued after a hearing where both parties are present. Typically lasts 1–2 years. You must change locks within 48 hours if this is the first plenary order.

If a tenant first presents an emergency order and then a plenary order (after the hearing), you are only required to change locks once—upon receipt of the emergency order. The plenary order is a continuation or renewal, not a new incident requiring another lock change.

Scenario 4: The Tenant Vacates After Lock Change

If the tenant terminates the lease or moves out shortly after you change the locks, you still absorbed the cost—and you cannot charge them for it or deduct from their deposit. If locks were changed due to 750/20 compliance, the cost is a landlord operating expense, not a tenant responsibility.

Scenario 5: Multiple Abusers or Orders

If a tenant presents multiple orders of protection (e.g., against two different household members), you must change locks within 48 hours of the first order. Subsequent orders do not trigger additional lock-change duties unless they identify different locks (e.g., a garage that wasn't covered by the first order). Consult an attorney for multi-order scenarios.

Integration with Lease Agreements and House Rules

Your lease should acknowledge 750/20 lock-change obligations. Include language such as:

"Landlord acknowledges that if Tenant obtains a court order of protection against a household member under the Illinois Domestic Violence Act, Landlord shall change or rekey all locks securing Tenant's unit within 48 hours. Tenant is not responsible for lock-change costs. Landlord will not retaliate against Tenant for exercising this right."

This language:

• Demonstrates your knowledge and compliance intent
• Reduces misunderstandings if an order is presented
• Protects you in retaliation disputes (shows good-faith commitment to law)
• Encourages tenants to report orders without fear

Do not include language that creates conditions, requires verification, or delays the process. Phrases like "upon reasonable notice" or "subject to landlord verification" are problematic and may be challenged as inconsistent with 750/20's mandatory 48-hour requirement.

Technology and Compliance: Managing Lock Changes Efficiently

For multi-unit landlords, maintaining compliance while protecting tenant privacy requires systems. Consider:

• Secure communication channels: Use encrypted email or a tenant portal to receive sensitive documents, reducing mail interception risks.
• Vendor management: Maintain a pre-vetted list of locksmiths with rapid response capabilities and confidentiality agreements.
• Internal tracking: Use a separate compliance log (password-protected, not in tenant files) to document orders, dates, and costs.
• Automated reminders: If an ex parte order is issued, set a calendar alert for the plenary hearing date to track renewal.
• Confidentiality protocols: Train all staff that domestic violence orders are confidential and not to be discussed with other tenants, maintenance staff, or third parties.

LeaseBase's compliance engine can help you track lock-change requests, vendor payments, and compliance dates in one secure location. Multi-unit landlords can assign these tasks to managers and monitor completion in real time, reducing the risk of missed 48-hour deadlines.

Frequently Asked Questions

Q: What if the tenant asks me to change locks but doesn't have an order of protection yet?

A: You have no legal obligation under 750/20 to change locks without a court order. However, you may have a contractual duty if your lease includes a broader security provision. If a tenant reports abuse and expresses safety concerns, you can:

• Advise them to seek an order of protection from the court (the Illinois Attorney General's office and local domestic violence agencies offer free assistance)
• Consider temporary measures, such as installing a temporary chain lock or deadbolt (at your discretion and cost)
• Recommend they contact the National Domestic Violence Hotline (1-800-799-7233) or a local shelter for resources and guidance

Once they present a valid order, you have 48 hours to comply with 750/20.

Q: Can I charge the tenant a one-time "domestic violence lock change fee" in the lease?

A: No. Any attempt to charge a tenant for lock changes required by 750/20 violates the statute and is unenforceable. Lock change costs are a landlord obligation, not a tenant cost. Including such a fee in the lease would expose you to retaliation liability and contract-unconscionability challenges.

Q: The abuser is pressuring me to give them a copy of the new keys. Can I?

A: Absolutely not. Once locks are changed pursuant to 750/20, you must not provide keys to the abuser or their agent under any circumstances, even if they claim a lease right to occupancy. The order of protection bars their residence, and providing keys would violate the order and expose you to civil liability from the protected tenant. If the abuser is a co-tenant with legal rights, a separate eviction or lease-termination proceeding is necessary—consult an attorney.

Q: I changed the locks within 48 hours, but the tenant is now claiming retaliation because I didn't reduce her rent that month. Is this retaliation?

A: No, not directly. Retaliation under 750/20 occurs when you punish the tenant *for exercising their right to a lock change*—for example, increasing rent, refusing renewal, or threatening eviction *because* they obtained a protection order. Failure to voluntarily reduce rent is not an adverse action. However, if the tenant believes your normal business practices (e.g., rent increase notice, non-renewal) are pretextual retaliation, they may file a retaliation complaint. Within 30 days of the lock change, any adverse action is presumed retaliatory unless you prove otherwise. Document your ordinary business reasons for any changes to the tenancy.

Q: What if I didn't know the tenant had an order of protection until 60 days later, when they mentioned it in passing?

A: Once you have notice of the order, the 48-hour clock starts—even if you receive notice belatedly. You should change the locks immediately at that point. However, late compliance does not eliminate your obligation, but it does create liability exposure. A tenant could argue that you failed to comply with 750/20 from the original date of the order. To protect yourself:

• Document the date you actually received notice in writing
• Immediately contact a locksmith and change locks within 48 hours of your receipt date
• Do not attempt to negotiate a later date or payment from the tenant
• If the delayed notice puts the tenant at ongoing risk, consider whether the abuser may still have old keys and take additional security measures

Q: Do I need liability insurance that covers domestic violence lock-change obligations?

A: Standard landlord liability insurance typically covers routine lock changes, but specific coverage for 750/20 compliance is rare. Review your policy with your insurance agent. Some policies include "protective actions" or "emergency safety measures" that may apply. Regardless, compliance with 750/20 is mandatory and cannot be delegated to insurance. Maintain compliance in all cases.

Staying Current: Law Changes and Resources

Illinois domestic violence law continues to evolve. Recent changes (2024–2026) include:

• Enhanced order of protection procedures: HB 5082 (2023) clarified that emergency orders remain in effect even if a defendant does not appear at the plenary hearing, strengthening protections.
• Landlord duties expansion: Ongoing legislative efforts seek to expand landlord responsibilities for tenant safety, including security upgrades and notice requirements. Stay informed via the Illinois Attorney General's office.
• Retaliation standards: Illinois courts have consistently broadened the definition of retaliation, making it easier for tenants to challenge landlord actions as retaliatory within the 30-day window.

Resources for staying compliant:

• Illinois Attorney General's Office: www.cyberdriveillinois.com/departments/index/domestic_violence/home.html — publishes guidance on landlord duties and enforcement actions.
• Legal Aid Chicago: Provides free information to tenants and can advise landlords on compliance questions.
• National Domestic Violence Hotline: 1-800-799-7233 — refers landlords to local resources and training.
• Illinois Domestic Violence Commission: Offers training and annual updates on law changes.

Compliance Conclusion: No Discretion, Clear Deadline, Real Penalties

765 ILCS 750/20 is straightforward: when a tenant presents an order of protection naming a household member as an abuser, you change the locks within 48 hours at your own cost. There is no ambiguity, no landlord discretion, and no tenant payment obligation.

Non-compliance carries criminal penalties (up to 6 months jail and $1,500 fine), civil liability (damages and attorney fees), and retaliation exposure. Compliance costs $50–$250 per unit and takes one business day. The financial and legal risk of non-compliance far exceeds the cost of compliance.

For landlords managing multiple units, the volume of lock-change requests remains low—most domestic violence survivors seek relocation rather than staying in the same building. However, when an order is presented, immediate action is not optional.

Document everything, maintain confidentiality, use a trusted locksmith, and keep detailed records. Your tenant's safety and your legal protection depend on it.

Next Steps: Ensure Your Portfolio is Compliant

If you manage Illinois rental properties, domestic violence compliance is non-negotiable. Self-managing landlords often overlook this requirement because it is state-specific and low-frequency—but a single violation carries serious consequences.

Review your lease agreements now to include 750/20 acknowledgment language. Build a vendor network of locksmiths who can respond within 48 hours. Train yourself and any property managers on the requirement.

For multi-unit landlords, consider using a compliance engine that flags state-specific obligations, tracks vendor performance, and documents lock-change compliance in a secure log. The cost is far less than a retaliation lawsuit or criminal charge.
