Few parts of a NYC lease cause more disputes — and more avoidable penalties — than the security deposit. Since New York overhauled its rules in 2019, the amount you can collect, how you have to hold it, and how fast you must return it are all tightly regulated. Get the mechanics wrong and you can owe a tenant far more than the deposit itself.
This guide walks NYC landlords through the current security deposit rules, the deductions you can (and can't) make, the deadlines that matter, and the paperwork that protects you.
How much can you collect? One month's rent — full stop
The single biggest change came from the Housing Stability and Tenant Protection Act of 2019 (HSTPA). For residential leases across New York State, the security deposit is capped at one month's rent.
That means the old playbook — first month, last month, and a security deposit up front — is no longer legal for residential tenancies. The total advance deposit you hold cannot exceed a single month's rent. It applies whether the apartment is rent-stabilized or free-market, and whether the tenant is new or renewing.
A few practical points:
- You cannot relabel money to get around the cap. Calling part of it a "move-in fee" or "pet deposit" that pushes the total over one month's rent won't hold up.
- The cap covers the security deposit specifically. Legitimate, separately authorized charges (like a bona fide application fee within the legal limit) are governed by their own rules.
- If you collected more than one month under an older lease, you should be prepared to reconcile that at renewal.
If you're not sure what a given unit can command in today's market — which drives the deposit amount — a property consultation is a good place to start.
Where does the deposit have to be held?
New York treats a security deposit as the tenant's money, held in trust — not the landlord's to spend. You must keep it separate from your own funds.
For buildings with six or more units, the law requires the deposit to be placed in an interest-bearing account in a New York bank. The interest belongs to the tenant, minus a small administrative allowance the landlord may retain. For smaller buildings, you're still obligated to keep the deposit segregated and to tell the tenant where it's held.
Commingling a tenant's deposit with your operating cash is exactly the kind of mistake that turns a routine move-out into a losing case in NYC housing court. Good property management software with proper trust-accounting — we use AppFolio — keeps these funds clean and auditable.
What can you legally deduct?
Here's where owners get into the most trouble. New York allows deductions from a security deposit only for specific, defined reasons:
- Unpaid rent the tenant owes.
- Damage beyond normal wear and tear caused by the tenant, their household, or guests.
- Cleaning, repairs, or replacements reasonably necessary to return the unit to its move-in condition — where the lease provides for it.
- Certain other costs expressly allowed by the lease, such as replacing lost keys or fobs.
What you cannot deduct for is ordinary wear and tear — the natural aging that comes from someone simply living in the apartment.
Wear and tear vs. damage
The line matters, so here's how it tends to break down:
| Normal wear and tear (landlord's cost) | Tenant damage (deductible) |
|---|---|
| Faded or minorly scuffed paint | Large holes, unapproved wall color, crayon murals |
| Worn carpet or flooring from foot traffic | Burns, pet stains, or tears in the carpet |
| Loose door handles, minor fixture wear | Broken doors, smashed fixtures, missing hardware |
| Lightly dirty surfaces at move-out | Excessive filth, grease, or trash left behind |
When in doubt, ask whether the condition resulted from ordinary use or from abuse or neglect. If it's the former, it's on you.
The 14-day return deadline is not optional
After a tenant vacates, you have 14 days to return the security deposit. If you're keeping any of it, you must send an itemized statement describing each deduction and the amount.
Miss the deadline and the consequences are severe: a landlord who fails to provide the itemized statement within 14 days generally forfeits the right to retain any portion of the deposit, regardless of how much actual damage there was. In other words, a late letter can cost you the entire deposit even when the deductions were legitimate.
And if a court finds you willfully violated the deposit rules, the tenant can recover up to twice the deposit amount in damages. This is why disciplined move-out timing isn't just good service — it's financial self-protection.
Document everything: the move-in / move-out inspection
Your best defense in any deposit dispute is evidence of the unit's condition at both ends of the tenancy.
New York gives tenants the right to a walk-through inspection before move-in, with the landlord present, and again before move-out so the tenant has a chance to fix issues before you inspect for damage. Take advantage of both:
- At move-in, walk the unit with the tenant, note existing conditions, and take date-stamped photos. Have both parties sign the record.
- Before move-out, offer the inspection in writing, then document the unit's condition again with photos.
- Keep the move-in and move-out records side by side so any deduction is tied to a clear, provable change.
Our property inspections service builds this documentation into every tenancy, and our move-in / move-out inspection checklist gives you a ready-made template if you're self-managing. Thorough inspection records are also central to how we screen and place tenants through our tenant placement service, so the tenancy starts on solid, documented footing.
Special situations NYC landlords ask about
Rent-stabilized apartments. The one-month cap and 14-day return rules apply here too. Because stabilized tenancies come with additional oversight from NYS Homes and Community Renewal (HCR) and its rent-regulation arm (DHCR), sloppy deposit handling can compound into a bigger compliance problem. Rent-stabilized and subsidized buildings are our core specialty, and deposit mechanics are one piece of a much larger compliance picture.
Source of income. You can't sidestep NYC's Human Rights Law with deposit terms. Charging a voucher holder a larger deposit, or refusing to hold one on the same terms as any other tenant, can amount to unlawful source-of-income discrimination. Apply identical deposit rules to every applicant.
Deposit disputes and nonpayment. A security deposit is not a substitute for the eviction process. You can apply it to unpaid rent at move-out, but you can't skip proper legal procedure while a tenant is still in possession — see our overview of the NYC eviction process for how that actually works.
The bottom line
NYC's security deposit rules reward landlords who are organized and punish those who improvise. Cap the deposit at one month's rent, hold it separately, deduct only for real damage or unpaid rent, document the unit's condition at both ends, and return what's owed within 14 days with an itemized statement. Do those five things consistently and deposit disputes largely disappear.
