A security deposit generally may not exceed one month’s rent or $100, whichever is greater (N.H. Rev. Stat. Ann. § 540-A:6). Give a receipt and hold the money in a separate account. Unused deposit plus an itemized list is generally due within 30 days.
New Hampshire does not prescribe a statewide 24-hour entry statute. Put a reasonable-notice entry clause in the lease. Emergency entry is customary.
A New Hampshire rent increase should be in writing. Many landlords use at least the same notice they would use to end a month-to-month tenancy. A month-to-month tenancy generally takes 30 days’ written notice (N.H. Rev. Stat. Ann. § 540:3). The lease may require more. Local rent-control rules can cap the amount even when the notice period is met.
