Landlord or Tenant: Who Handles Pests in a New York City Building?

Who is responsible for pests in a New York apartment?

Mainly the owner. The Housing Maintenance Code requires an owner of a dwelling to take reasonable measures to keep the premises free from pests, to prevent foreseeable conditions, and to remediate them and any underlying defect promptly. The tenant's role is to report, cooperate and keep the unit in reasonable order.

That answer surprises people who expect pests to be a housekeeping matter. In an attached building, a pest in one flat usually came from, or is moving to, another. Roaches move between apartments through shared walls and utility spaces, and a pest-industry source, Professional Pest Manager, cites studies saying up to 30% of a German cockroach population may move between apartments in a week where construction allows. A tenant cannot treat a wall they do not control.

That does not mean tenants have no part. We did not source a precise tenant duty for access, housekeeping or reporting, so we do not state one as law. What we can say is that reporting early and in writing, giving access for treatment and following preparation instructions are what make owner treatment work.

The table below sets out the main sources of owner duties we can point to. Use it as a map, and read the primary text if a dispute is serious.

What does the owner actually have to do?

Owners have to act on pests as a building condition: inspect, treat and repair what lets pests in. That includes common areas, cellars and shared walls, and not only a reporting tenant's unit. Reasonable measures usually means a pest control visit plus follow-up on the defect, such as gaps, damaged walls or trash storage.

The phrase the code uses is about conditions, not only creatures. An owner who sprays a kitchen and leaves a hole around a pipe has treated the symptom. The Housing Maintenance Code language refers to remediating the underlying defect, which fits an integrated approach.

NYC's Department of Health and Mental Hygiene publishes Integrated Pest Management guides and a toolkit that describe the same idea. IPM is prevention-based, targets underlying causes such as holes and gaps, and includes HEPA vacuuming and sealing around pipes and conduits. A journal summary reports that apartments receiving IPM had significantly lower roach counts at three months and greater success at three and six months.

In practice, an owner's response often includes an inspection, treatment of reported units and neighbours, sealing of entry points, and a record. Our multi-unit building pest control and rodent exclusion and sealing pages describe how that looks from a technician's side.

What is Local Law 55 and why does it matter?

Local Law 55 of 2018 requires owners to inspect all occupied units and common areas every year for indoor allergen hazards, including pests, mold and moisture. It turns pest checking from a reaction to complaints into a scheduled duty, which matters most in older attached buildings.

For an owner, this is a reason to keep inspection notes. A record of what was checked, when and by whom is the most direct way to show the building is looked after if HPD asks questions.

For a tenant, it is a reasonable thing to ask about. You can ask the owner or managing agent when the last annual inspection of your unit and the common areas took place. A routine inspection is also a chance to point out damp, gaps and droppings that you may not have reported.

We have not sourced the penalty for missing an inspection, so we do not state one.

Why does one unit's treatment often fail in a shared building?

Pests do not respect apartment lines. If only one unit is treated, mice and roaches can return from the neighbouring unit, the cellar or a pipe chase. That is why building-wide inspection and sealing often decide whether a repair holds, and why owners and managing agents usually need to coordinate.

Attached New York buildings share walls, risers and cellars. Shared walls, basements and utility spaces make it easy for mice to travel between apartments undetected, according to contractor Positive Pest, which is an industry opinion rather than a study. The pest-industry source on roaches points the same way.

For tenants, that gives a practical reason to tell neighbours and the managing agent when you report a problem. If three flats on one stack have the same issue, a single combined report is harder to set aside than three separate ones. For owners, it explains why a technician may ask to see adjoining units and the cellar. Pages such as mouse control and German cockroach control describe how a technician handles that.

What about rats, cellars and the building's outside?

Article 151 of the NYC Health Code requires owners to keep property free of rats and to address the conditions that lead to them. That covers yards, cellars and trash storage, not only living spaces. Since 2024, residential buildings of one to nine units also have to use lidded bins.

Rats are an exterior and cellar problem as much as an apartment one. Trash set at the kerb, loose bags and open storage give them food, and tree pits, rear yards and cellars give them cover. NYC has designated eight rat mitigation zones, chosen as high priority from 311 complaints: Bushwick, Bedford-Stuyvesant and Prospect Heights in Brooklyn, the Grand Concourse in the Bronx, and Harlem, Chinatown, East Village and the Lower East Side in Manhattan. Zones get more enforcement on properties that fail inspections.

Residential buildings of one to nine units must put trash in bins of 55 gallons or less with secure lids, from November 12, 2024, with fines from January 2, 2025. We did not source rules for buildings of ten or more units, so we do not describe them. Our trash containerization guide covers the timeline, and rat control and cellar and basement pest control cover treatment.

What should a tenant do when pests appear?

Write to the owner or managing agent describing the pest, where you saw it and when, keep a dated copy, photograph evidence, and give access when treatment is arranged. If nothing is fixed, call 311. This is general guidance, not a statement of a legal duty.

A short email or letter is enough. Name the pest, the room, the date you first saw it and any neighbours who have the same issue. Photos of droppings, gaps around pipes or live pests help. Ask for a date for treatment.

Prepare for the visit as instructed. A technician may ask you to clear under sinks, move furniture from walls or bag laundry. Skipping those steps is a common reason a treatment does not work.

If the owner does not respond, 311 is the next route, and HPD can cite owners for pests. A contractor blog says mice, rats or roaches in an apartment or common area are an immediately hazardous violation that generally gives owners 21 days to correct. We could not confirm that from an official source, so treat the class and timing as unverified.

While you wait, you can call (855) 974-4733 for advice or to arrange a visit of your own. Phones are answered 24/7, and a technician can often visit the same day when one is free.

What if you are a co-op or condo owner, or a commercial tenant?

The rules above describe owners of dwellings and multiple dwellings. If you own a co-op or condo unit, your building's governing documents and board may decide who arranges treatment in your unit and in common areas. Commercial tenants usually look to their lease. Check the documents before you act.

In a co-op or condo, the board or managing agent handles the building's shared walls, cellar and roof, and the unit owner often handles the interior. The line between the two is where disputes come from, so a written report to the managing agent is useful there too.

Restaurants are a special case because kitchens often sit under flats. Businesses citywide had to containerize trash from March 1, 2024, and food-related businesses from September 1, 2023. See restaurant and commercial pest control for how a technician treats a ground-floor kitchen with homes above it.

We are not a law firm and this page does not give legal advice. If you are in a dispute over repair obligations, an attorney or a tenant organization can advise.

How can an owner respond to a pest violation?

Start with an inspection, arrange treatment by a certified applicator in the right NYSDEC category, fix the defect that let pests in, and keep written service reports. A violation is easier to answer when each step is documented and dated. A technician can usually supply that report after each visit.

Owners who receive a citation often feel pressure to act fast. Speed matters, but a record matters just as much, because the question is whether reasonable measures were taken and the cause remedied.

Work should be done by a certified applicator in the right NYSDEC category. New York State's Department of Environmental Conservation issues the credentials, and Category 7A, Structural and Rodent Control, covers pest control in and around structures, including rodents, roaches, ants and stinging insects, but not termite treatment. Ask for credentials before you hire. See hiring a pest company in New York and landlord pest violation response.

For a building in New Jersey, such as one in Jersey City or Newark, New Jersey work follows New Jersey rules and the New York duties above do not apply.
