Written statement with itemized deductions required
Regardless of the deposit amount, landlords must follow the correct procedures for holding, itemizing, and returning the deposit. Failure to follow these procedures can result in the landlord forfeiting the right to make deductions and owing penalties to the tenant.
After a tenant moves out, New Hampshire landlords have 30 days to either return the full security deposit or provide an itemized list of deductions along with any remaining balance.
