Finding mice in your NYC apartment isn't just unsettling, it's a housing code violation your landlord must fix. Whether you're renting in Brooklyn, Manhattan, or Queens, New York City law requires landlords to keep rental units pest-free. This includes paying for professional extermination and sealing entry points that allow rodents inside.
NYC landlords are legally responsible for mice infestations under Housing Maintenance Code Section 27-2018. They must provide extermination services, seal holes and cracks, and maintain the building to prevent rodent entry. Tenants can file complaints through 311 or HPD if landlords fail to address mouse problems within reasonable timeframes.
NYC Housing Code Requirements for Rodent Control
The New York City Housing Maintenance Code treats rodent infestations as Class B violations, meaning landlords have 30 days to correct the problem once notified. This applies to all rental properties, from luxury high-rises to rent-stabilized apartments in older buildings.
According to NYC Housing Preservation and Development (HPD), property owners must:
- Inspect for rodent activity monthly in common areas
- Seal all holes larger than 1/4 inch with steel wool and caulk
- Install door sweeps where gaps exceed 3/8 inch
- Provide covered trash receptacles in sufficient numbers
- Remove garbage daily from buildings with 9+ units
These requirements apply year-round, not just when tenants complain. Landlords who ignore these responsibilities face fines starting at $300 per violation, with repeat offenses reaching $1,000.
Documentation Requirements for Tenants
Before escalating to city agencies, document everything. Take timestamped photos of mouse droppings, gnaw marks, and entry points. Save all written communication with your landlord or management company. Email creates better evidence than texts or phone calls.
Send your initial complaint in writing via certified mail or email, stating: "I have observed mice in my apartment at [specific locations]. Please arrange for professional extermination and seal all entry points within 7 days as required by NYC Housing Code."
When Do Landlords Have to Pay for Extermination?
Landlords must pay for professional pest control services in nearly all situations involving mice. The only exception occurs when tenants directly cause the infestation through extreme unsanitary conditions that violate their lease agreement.
Even if your apartment has food debris or clutter, landlords remain responsible for structural issues that allow mice entry. A messy apartment doesn't excuse a landlord from sealing holes in walls, fixing gaps under doors, or addressing building-wide infestations.
For buildings with three or more units, landlords must use licensed pest control professionals who follow Integrated Pest Management (IPM) protocols. DIY solutions like glue traps or over-the-counter poisons don't meet legal requirements.
Timeline for Landlord Response
Once notified in writing, landlords have specific timeframes to act:
- Immediate response (24-48 hours): Acknowledge the complaint and schedule inspection
- Within 7 days: Conduct professional inspection and begin treatment
- Within 30 days: Complete all necessary repairs and follow-up treatments
- Ongoing: Provide monthly treatments if needed until resolved
How to File a 311 Complaint for Mice in Your Apartment
When landlords ignore mouse problems, filing a 311 complaint triggers city inspection. You can file online at NYC.gov, call 311, or use the NYC 311 mobile app. Choose "Rodents" as the complaint type and "Residential Building" as the location.
Include specific details: which rooms have mice, how long the problem has existed, and what communication you've had with your landlord. Upload photos if filing online. Request an HPD inspection rather than just logging a complaint.
HPD inspectors typically arrive within 2-3 weeks. They'll document violations and issue a Notice of Violation to your landlord. Class B violations for rodents give landlords 30 days to fix the problem or face escalating fines.
Escalating Beyond 311
If 311 complaints don't resolve the issue, consider these options:
- Contact your City Council member's constituent services office
- File a decrease in services complaint with DHCR (for rent-stabilized units)
- Initiate an HP action in Housing Court for repairs
- Withhold rent in escrow (consult a tenant attorney first)
Special Rules for Brooklyn Rent-Stabilized Apartments
Rent-stabilized tenants in Brooklyn have additional protections through the Division of Housing and Community Renewal (DHCR). Mouse infestations qualify as a "decrease in required services," potentially warranting rent reductions.
To file a DHCR complaint, use Form RA-81 (Individual Tenant Statement of Complaint). Document that you notified your landlord in writing and they failed to resolve the issue within reasonable time. DHCR can order rent reductions retroactive to your complaint date.
Market-rate tenants don't have DHCR protections but can still pursue rent abatement through Housing Court if mice make the apartment partially uninhabitable. Courts typically award 10-20% rent reduction for the period of active infestation.
Frequently Asked Questions
Can my landlord charge me for mouse extermination in NYC?
No, landlords cannot charge tenants for mouse extermination unless the tenant directly caused the infestation through lease violations. NYC Housing Code makes pest control a landlord responsibility, including all costs for professional extermination and preventive measures.
What if my landlord says mice are my fault because of food or clutter?
Even if your housekeeping isn't perfect, landlords must still seal structural entry points and provide extermination. Mice enter through building defects like holes in walls, gaps under doors, and openings around pipes. These structural issues remain landlord responsibilities regardless of apartment cleanliness.
How many times must an exterminator visit to eliminate mice?
Professional rodent control typically requires 2-3 initial visits plus monthly follow-ups until the problem resolves. Single treatments rarely work because mice reproduce quickly. Landlords must continue treatments until the infestation ends, not just provide one-time service.
Can I break my lease due to a mouse infestation in NYC?
Yes, severe rodent infestations that landlords refuse to address may constitute "constructive eviction," allowing lease termination without penalty. Document all issues, give written notice with reasonable cure period (usually 30 days), and keep evidence of the ongoing problem. Consult a tenant attorney before moving out.
What proof do I need to show mice came from neighboring apartments?
You don't need to prove the source. Once you report mice, landlords must inspect and treat the entire building if necessary. Building-wide infestations require comprehensive treatment of all affected units, basements, and common areas at the landlord's expense.
Protecting Your Rights During the Extermination Process
Landlords cannot require you to miss work for exterminator visits. They must offer reasonable scheduling options, including evenings or weekends. If they insist on weekday-only appointments, they should provide building staff to grant access.
You have the right to know what pesticides will be used. Under NYC Local Law 37, landlords must provide 48-hour notice before applying certain chemicals. Request IPM methods that minimize pesticide use, especially if you have children, pets, or health conditions.
During treatment, exterminators should focus on exclusion first, sealing holes with steel wool and caulk. Bait stations come second, placed in areas inaccessible to children and pets. Spraying should be minimal and targeted, never broadcast throughout living spaces.
Temporary Relocation Rights
Severe infestations might require temporary relocation during intensive treatment. Landlords must pay for comparable housing if the apartment becomes uninhabitable due to their failure to maintain the property. This includes hotel costs or temporary apartment rentals.
Document any expenses related to the mice problem: damaged food, cleaning supplies, medical bills from mouse-related illness. You can pursue reimbursement through small claims court if your landlord's negligence caused these losses.
Take Action Today to Resolve Your Mouse Problem
Don't wait for mice problems to worsen. Document the infestation now, notify your landlord in writing, and know your rights under NYC housing law. If your landlord fails to provide proper professional pest control services, file a 311 complaint immediately.
For severe infestations or unresponsive landlords, contact a tenant rights attorney through Housing Court Help Center. Many offer free consultations for rent-stabilized tenants. Remember, NYC law is on your side, landlords are responsible for keeping your apartment mouse-free, and you have multiple ways to enforce that right.
