Late Fees and Security Deposits in NYC: What's Actually Legal

In New York, a late fee applies only to rent, never to a security deposit, and it is capped at $50 or 5% of the monthly rent, whichever is LOWER (in NYC that is almost always $50). It can only be charged after a 5-day grace period. The deposit itself is capped at one month's rent and must come back within 14 days of move-out with an itemized statement, or the landlord can forfeit the right to keep any of it.

These are small numbers with a big pattern: landlords and portals routinely charge above them, and the fees vanish the moment a tenant cites the statute. Here is each rule, the law behind it, and the exact move that works.

What's the maximum late fee in NYC?

RPL section 238-a sets it: $50 or 5% of the monthly rent, whichever is lower. On any rent above $1,000 that means $50, period. And the fee cannot be charged at all until rent is at least 5 days late.

A $100 late fee, a "10% penalty," a daily accumulating charge: not enforceable, no matter what the lease says. A lease cannot contract around the statute.

What to do: If a late fee exceeds $50 or lands before day 6, dispute it in writing and cite RPL 238-a by name.

Can a landlord charge a late fee on a deposit payment?

No. This one is blunt: late fees apply to rent. The law does not permit fees on deposits.

A real case from Reddit: a landlord billed a $100 late fee on a $150 security deposit top-up that had been quietly added to the payment portal while the tenants were on autopay. Two problems at once: a fee on a deposit (not allowed) and $100 (over the cap even if it were rent). The tenant disputed it in writing, and two days later posted: "THANK YOU! ... the late fee was gone."

What to do: Fee attached to anything that is not rent? Point at the statute. Most landlords drop it as soon as they see you know the rule.

How big can a security deposit be?

One month's rent. That is the ceiling since the 2019 rent laws, for market-rate and stabilized units alike. "First, last, and security" adds up to an illegal demand in New York: last month's rent on top of a one-month deposit exceeds the cap.

While you live there, the deposit is your money held in trust. In buildings of 6+ units, it must sit in a New York bank account, and you are entitled to know where.

What to do: At signing, count what is being collected. First month plus one month deposit plus a maximum $20 application fee is the whole legal list for a landlord.

When do I get the deposit back?

Within 14 days of moving out. If the landlord keeps any part, they owe you an itemized statement in the same window explaining each deduction. Miss the window or skip the itemization, and the landlord can forfeit the right to retain anything at all.

Vague deductions do not count either. One renter got "random Zelle screenshots with no company names or descriptions of work" as justification. That is not an itemized statement.

What to do: Photograph the empty unit on move-out day, hand over the keys with a written date, and start the 14-day count. Day 15 with no deposit and no statement: demand letter citing GOL 7-108, then small claims court if needed.

Can the landlord condition my deposit on something else?

No. The deposit is owed on the unit's condition, not on your behavior after moving out. A management company told one stabilized tenant they would only discuss returning her deposit if she withdrew a pending DHCR overcharge case first. That is coercion layered on a deposit violation, and for a stabilized tenant it also walks into tenant-harassment territory.

What to do: Never trade a legal claim for your own money. The deposit and any dispute are separate lanes. Report pressure like this to HCR and the AG's office.

Common questions

My lease says the late fee is $100. Doesn't the lease win?

No. A lease clause cannot override RPL 238-a. The enforceable maximum is $50 or 5%, whichever is lower, after the 5-day grace period.

Is charging last month's rent upfront legal in NYC?

For a standard landlord lease, no. The deposit cap is one month, and collecting last month's rent on top of a deposit exceeds it. The legal upfront list: first month, one month deposit, up to $20 application fee.

What happens if the landlord misses the 14-day deadline?

They can forfeit the right to keep any portion of the deposit, even for real damage. Courts in New York have applied that consequence. Document your move-out date and hold the line.

Are condo and co-op fees covered by the $20 application cap?

Watch this one: the $20 cap applies to the landlord's application fee. A condo or co-op BOARD's application fee is a separate charge and is not capped. A $200 board fee with a real, formal process can be legitimate. A "$50 application fee" over Venmo from someone with no listing and no process is a different story.
