Short answer: in New York, keeping a rental free of rodent infestation is the property owner's responsibility. Tenants should report it early and in writing, keep food sealed, and give access for treatment. Landlords should treat the whole building, not the complaining unit, because in a Buffalo double a rodent route serves every unit at once.
Buffalo's rental stock is doubles: two units, one shell, one wall and chase system. Mice entering at the foundation reach both kitchens. Trapping the unit that complained while the other unit and the shell stay open buys a quiet month and a repeat call, and the repeat call usually comes with a complaint history attached. The fix that holds is a whole-building inspection, removal across the building, and sealing of the shell, with the findings in writing. That document matters: it is your record for the tenant conversation, for a sale, and for showing the work was done properly if a complaint reaches the city or the county. The residential page lays out the whole-building approach.
An inspection names the animal, the scale of the problem and the entry points, with the price for each part in writing.
Move-in discovery. A new tenant finds droppings in the first week. This is a landlord fix, and a fast inspection settles whether it is an old, inactive problem or a live one, which changes the conversation completely. Student rentals near UB in Amherst: turnover and casual food storage make a move-out inspection in May the cheapest rodent control of the year. Village doubles in places like Depew: older shells, tight lots, and shared routes, where whole-building sealing ends a pattern that single calls never did. Larger properties: buildings big enough to need monitoring and reporting run under the commercial program instead.
Erie County's free rodent program baits qualifying owner-occupied homes of four units or fewer. It does not cover larger rentals, does not do indoor trapping, exclusion or cleanup, and it is not a substitute for the building work. Our Erie County guide explains exactly what the county covers and how complaints are investigated, which is also the route when the source property is a neighbor's rather than yours.

That is a legal question with fact-specific answers, and this page is not legal advice. What we can say practically: a documented, promptly treated problem rarely reaches that point, and the paper trail, report, inspection, work record, is what every side of the conversation ends up using.
Your building is still yours to seal and treat, and doing so protects your tenants regardless of the source. The source property itself is a code and county matter; Erie County investigates rodent complaints about problem properties, as the county guide explains.
Promptly, and visibly. An inspection booked within days, with the tenant told the date, defuses most situations. Rodent problems grow on a breeding clock, so a month of delay is also a bigger and more expensive problem, apart from the relationship cost.
