Mold in a Rented Home: Who Has to Fix It, and Who Pays

In a rented home it is almost always the landlord's to fix and to pay for, and a lease clause saying otherwise is void, because every New York residential lease carries a warranty that the place is fit to live in. What you control is the paperwork: a written request first, then your municipality's code enforcement office if nothing happens.

The warranty you cannot sign away

Start from the strongest thing you have. Real Property Law section 235-b puts into every residential lease in New York a warranty that the premises and the common areas are fit for human habitation and free of conditions dangerous, hazardous or detrimental to life, health or safety, and it makes void as contrary to public policy any agreement in which a tenant waives or modifies that right. So the clause in your lease putting damp on the tenant does not do what the landlord thinks it does. This matters to a lot of households here: renters hold 43,908 of the 81,645 occupied homes in Yonkers against 37,737 held by owner occupiers, so the majority of people reading a page like this cannot commission the work and do not have to fund it either.

Which rulebook a Yonkers landlord answers to

Knowing the right statute saves you being talked past. Multiple Residence Law section 3 applies the chapter to all cities under three hundred twenty-five thousand people and to all towns and villages, and the American Community Survey five year estimates put Yonkers at 209,978, comfortably inside that. So a Yonkers building is governed by that state statute rather than by a separate city housing maintenance code, and enforcement runs through the city's own Department of Housing and Buildings. The practical consequence is that advice written about housing maintenance violations twenty minutes south does not transfer, and quoting the wrong code at a landlord loses you the argument you were winning.

Put it in writing, then go to the code office

New York State Department of Health publication 7287 gives tenants a two step route and it costs nothing. Where growth is persistent or there are water leaks, ask the landlord or the superintendent to inspect and repair. If the landlord does not act, ask the local building department or the code enforcement official to inspect the home for water damage or leaks. Do the first step in writing even if you have already said it out loud, because the written version is what the second step runs on. Include where it is, roughly how big the patch is, how long it has been there, anything you can see about the water, dated photographs, and the date of any earlier conversation. Most landlord disputes in this trade are not about the mold, they are about who said what and when.

Mount Vernon: the same lever, a different counter

The tenant route is the state's, so it works identically across the towns on this site, but the office at the other end is local. Mount Vernon is a renter majority city too, with 16,021 of its 28,078 occupied units rented and 6,136 units sitting in buildings of 50 or more, so the same conversation happens there at scale. The city told the county planners that its Department of Buildings is responsible for floodplain management and that the service it provides under the flood insurance program is permit review. Useful to know, because if the repair to your building involves work in a flood hazard area, the permit question surfaces at that department and it is better raised before the work is scheduled than after it has stopped.

In a co-op the board decides, and that is usually good news

If you own a co-op apartment, do not start by hiring anyone. Publication 7287 notes that a co-op or condominium owner may need to arrange mold assessment and remediation through the building's management company or owners' association rather than directly, and in a building where the corporation owns the structure, going it alone can breach the proprietary lease and leave you paying for work the building would have funded. This is the normal case in Bronxville, where 1,881 of 2,233 occupied units, about 84 percent, are owner occupied while about 48 percent of the village's units sit in buildings of ten or more. Owner occupiers living in apartment buildings means co-ops, and it means the managing agent is your first email. We are happy to deal with a managing agent directly; say so on the form and we will approach it that way.

In a large building, the wall is not yours

Even as a renter with a cooperative landlord, the boundary of what can be opened is not obvious. Of the 85,006 housing units in Yonkers, 22,278 are in buildings of 50 or more units and a further 10,123 in buildings of 20 to 49, against 21,030 single family detached houses. Nearly two homes in five are in a large apartment building, where the wall cavity, the riser and the common areas belong to the building and not to the occupant. That decides who can authorize the work, and it also decides scope: growth fed by a leaking riser will come back in your apartment however carefully your unit is cleaned, because the water is in a part of the structure you do not control. Saying which of these you are in, when you send the details, is the single most useful line on the form.

The flood history is a tenant's right as well

One more thing to ask for in the same email, and almost nobody does. Since 15 August 2022 a Westchester owner has owed every prospective tenant a written flood history for the previous ten years before the lease is entered into, and that duty reaches renewals as well as new lettings, so if you have renewed since that date you should have received one. Where it was not provided and the tenant later suffers flood damage during the lease, section 581.31 allows the tenant to bring an action to recover those damages. For a damp problem, the value of the document is simpler than litigation: it tells you whether this building has done this before, which is the difference between a repair and a pattern.

For the landlord or the managing agent reading this

What closes a mold job properly is the report at the end of it, not the invoice. Section 947 of the Labor Law requires a mold assessment licensee to carry out a post remediation assessment, confirm the work area is free from all visible mold and that the work matches the plan, and issue a written passed clearance report, and it stops the containment coming down before that report exists. That document is what answers the next tenant, the next insurer and the next attorney, and it only exists if the sequence ran correctly, with the assessment before the removal and an independent party at the end. Send the property details through the form on this page and we will book the assessment first and run the order from there.
