Security Deposit Laws in New Hampshire
How long does a landlord have to return a security deposit in New Hampshire?
Under N.H. Rev. Stat. § 540-A:7, a landlord in New Hampshire has 30 days after you move out to either return your full security deposit or provide an itemized statement of deductions along with any remaining balance.
Important New Hampshire-specific details
Does not apply to owner-occupied buildings with fewer than 6 units (with some exceptions).
What happens if the landlord misses the deadline in New Hampshire?
Missing the deadline has real consequences for landlords in New Hampshire. Under the statute, the penalty is: 2x wrongfully withheld amount.
In practice, this means if your landlord doesn't return the deposit (or a proper itemized statement) within 30 days, you likely have a strong case in small claims court.
What can the landlord legally deduct from your deposit in New Hampshire?
New Hampshire law generally allows landlords to deduct for:
- Unpaid rent
- Damage to the unit beyond normal wear and tear — holes in walls, broken fixtures, stains, pet damage
- Cleaning costs, if the unit is left noticeably dirtier than at move-in
- Breach-of-lease costs, such as early termination fees where legally permitted
Landlords cannot deduct for normal wear and tear — faded paint, worn carpet from regular use, minor scuffs, or small nail holes from hanging pictures.

What to do if your landlord won't return your deposit in New Hampshire
- Send a demand letter by certified mail. Cite N.H. Rev. Stat. § 540-A:7 and the amount owed. Keep a copy and the delivery receipt.
- Give the landlord a reasonable response window — typically 7 to 14 days after the demand letter.
- File in small claims court. In most states you can sue for up to $5,000–$10,000 without a lawyer. Filing fees are usually $30–$75 and often recoverable as costs.
- Bring evidence. Lease, move-in and move-out photos, the demand letter, proof of delivery, and any communications with the landlord.
