New Hampshire Security Deposit Law: Deadlines & Penalties
New Hampshire landlords must return a security deposit, plus any interest owed, within 30 days after the tenancy ends. The landlord may deduct the cost of repairing damage beyond reasonable wear and tear, unpaid rent, a share of real estate taxes if the lease requires it, and other lawful unpaid charges under the lease. Deposits are capped at one month's rent or $100, whichever is greater.
Every deduction has to appear on a written, itemized list. For damage, the list must describe each repair with particularity and be supported by evidence such as estimates, bills, invoices or receipts. A landlord isn't liable if they couldn't comply because the tenant didn't provide a new address, and deposits left unclaimed for six months can become the landlord's property.
A landlord who violates the return rules can be ordered to pay twice the amount of the security deposit plus interest, minus any payments already made and lawful charges. Deposits held for a year or more earn interest at the savings rate of the bank where they are held. These rules don't cover someone renting out a single-family home who owns no other rental property, or units in an owner-occupied building of five units or fewer, unless the tenant is 60 or older.

New Hampshire: common questions
How long does a New Hampshire landlord have to return a deposit?
30 days after the tenancy ends. The landlord must return the deposit and any interest, or send a written itemized list of deductions describing each repair or charge, along with the remaining balance.
Why does a forwarding address matter in New Hampshire?
A landlord isn't liable for missing the rules if the problem was caused by the tenant not providing a new address. Deposits and interest left unclaimed for six months after the tenancy ends can become the landlord's property, so give your address in writing promptly.
Does my New Hampshire deposit earn interest?
Yes, if the landlord held it for a year or more. Interest is paid at the rate the bank or credit union pays on regular savings accounts. On request, the landlord must tell you where the deposit is held and the interest rate.
What penalty applies, and where can I sue in New Hampshire?
A landlord who violates the return rules can owe twice the deposit plus interest, minus payments made and lawful charges. New Hampshire small claims cases can involve up to $10,000, not counting interest and costs.
