Can a Landlord Keep Your Deposit for Mold?
· NYC Mold Removal Services
When mold can and cannot be charged against a NYC security deposit, what the 14-day itemization rule means, and how to protect yourself.
Tenants moving out of an apartment that had a mold problem often get a deduction for it, and the deduction is frequently improper. The distinction that matters is whether the condition came from the tenant's conduct or from the building, and in the overwhelming majority of mold cases it is the building.
This is general information about how the rules work, not legal advice.
The Rule That Does Most of the Work
New York's Housing Stability and Tenant Protection Act set out requirements that favor a documented tenant. The ones that matter here:
- An owner must return the deposit, or the balance of it, within 14 days of the tenant vacating.
- If any amount is withheld, the owner must provide an itemized statement describing the basis.
- Failing to provide that statement within 14 days generally forfeits the right to retain any portion of the deposit.
- A tenant has the right to request a walk-through inspection before move-out and to be present at it, with notice of what the owner would charge for so the tenant can cure it.
That last point is underused. Requesting the pre-move-out inspection in writing surfaces any intended mold charge while you still have the apartment and can document the condition.
Wear and Tear Versus Damage
Owners may deduct for damage beyond ordinary wear and tear. They may not deduct for ordinary wear and tear, and they may not use the deposit to fund repairs that were their obligation.
Where mold falls depends entirely on cause.
| Cause | Typically the owner's cost |
|---|---|
| Leaking riser, roof, or facade | Yes |
| Water from the unit above | Yes |
| Condensation on an uninsulated exterior wall | Yes |
| No ventilation in a windowless bathroom | Yes |
| Chronic below-grade damp | Yes |
| Growth that was reported and never repaired | Yes |
| Tenant's own unreported overflow or burst fixture | Possibly chargeable |
| Deliberate damage during removal attempts | Possibly chargeable |
The overwhelming majority of NYC mold originates in building systems and envelope, not in tenant behavior. An owner deducting for mold is implicitly claiming the tenant caused it, and that claim should be supported.
"You Didn't Ventilate Enough"
This is the common argument and it is usually weak. Humidity from normal occupancy, cooking, showering, drying laundry, does not by itself produce the kind of growth that leads to a remediation charge in a properly built and maintained unit. Where humidity does drive growth, the underlying cause is usually absent insulation, a failed or missing bathroom exhaust, or windows that cannot be opened, all of which are the owner's responsibility.
If an owner raises this, the question back is what moisture source they identified and what they did about the ventilation when the condition was reported.
Protecting Yourself
At move-in. Photograph everything, dated, including inside closets, under sinks, behind where furniture will sit, and around windows. Preexisting staining you did not record becomes your problem at move-out.
Throughout the tenancy. Report every condition in writing and keep the copy. A documented report that went unrepaired is close to fatal to a later claim that you caused the damage.
Before leaving. Request the walk-through inspection in writing. Photograph the entire apartment again on the final day, dated, with a scale object where there is any staining.
After leaving. Note the 14-day date. If nothing arrives, that silence is significant.
If You Are Charged Anyway
Write to the owner requesting the itemized statement if it was not provided, and ask specifically what moisture source they attribute the growth to. Attach your move-in photographs and any written reports you made about the condition during the tenancy. Where the amount is substantial and the owner will not engage, small claims court is the usual route, and a tenant attorney or legal services organization can advise on whether the facts support it.
If the mold condition was significant during the tenancy and was reported and not addressed, that history is relevant well beyond the deposit. See NYC landlord mold liability and documenting mold for housing court.
Frequently Asked Questions
How long does a NYC landlord have to return a security deposit?
Fourteen days from the tenant vacating. If any amount is withheld, an itemized statement explaining the deduction must be provided in that window, and failure to do so generally forfeits the right to retain any part of the deposit.
Can a landlord charge me for mold I reported and they ignored?
That is a difficult position for an owner. A dated written report that went unrepaired undercuts a claim that the tenant caused the condition, which is why keeping copies of every written notice matters so much.
Is mold normal wear and tear?
Mold is usually neither wear and tear nor tenant damage, it is a building condition arising from a moisture source the owner controls. Deductions are only appropriate where the tenant actually caused the water, such as an unreported overflow.
What is the pre-move-out walk-through inspection?
A tenant has the right to request an inspection before vacating and to be present, with notice of what the owner would propose to charge for, so the tenant has an opportunity to cure it. Requesting it in writing surfaces any intended mold charge while you can still document the apartment.
What if the landlord blames poor ventilation?
Ask what moisture source they identified and what was done about ventilation when the condition was reported. Normal occupancy humidity does not usually produce remediation-scale growth in a properly maintained unit, and missing exhaust or absent insulation is the owner's responsibility.
