New Hampshire Security Deposit Rules (2026)

New Hampshire RSA 540-A currently caps a security deposit at one month’s rent or $100, whichever is greater. Landlords must provide a condition-notice process at move-in, hold covered deposits in trust, and return the deposit and interest due within 30 days after termination, subject to lawful deductions.
