New Hampshire Basement Apartment Rental Laws Explained

If you're considering renting a basement apartment in New Hampshire, it's important to understand the unique legal requirements and protections that apply to this type of housing. Basement rentals can offer affordability and flexibility, but they must meet state safety, zoning, and tenant rights standards. This guide covers what renters need to know about laws, safety codes, and essential protections under New Hampshire law.

Understanding Basement Apartment Rentals in New Hampshire

Basement apartments—sometimes called accessory dwelling units (ADUs)—are only legal if they comply with local building, zoning, and health codes. Not every basement unit is automatically approved for rental. For your safety and rights, always verify these basics before signing a lease:

• Legal Status: The unit must have permits as a legal rental from the town or city.
• Safety Codes: Must meet building codes for ventilation, windows (egress), heat, and smoke/carbon monoxide detectors.
• Health Requirements: Must provide adequate light, sanitation, and safe exits.

You can confirm a basement unit's approval status with your local municipality or building department. If in doubt, ask your landlord for documentation.

Key Legal Protections for Basement Apartment Renters

In New Hampshire, renters—including those in basement or accessory apartments—are protected under the New Hampshire Revised Statutes Annotated (RSA) Chapter 540: Landlord and Tenant^[1]. This law covers:

• Written Leases: Most rentals, especially unique units like basement apartments, should use a written lease spelling out terms.
• Security Deposits: State law limits deposits to one month's rent or $100, whichever is greater, with required receipt and return procedures.
• Eviction Protections: Landlords must have legal grounds and follow proper notice if seeking eviction.

Health and Habitability Requirements

Your landlord must provide a safe, healthy living environment, even in a basement apartment. Under New Hampshire law, renters have the right to:

• Proper heating and plumbing
• Working smoke and carbon monoxide detectors
• Safe emergency exits (egress windows can be essential in basement units)
• Freedom from water leaks, mold, or pest infestation

If these are missing or ignored, you can notify your landlord in writing. For ongoing issues, you may contact the New Hampshire Department of Justice - Consumer Protection & Antitrust Bureau or the local health officer.

Filing a Complaint About Unsafe Conditions

If your basement apartment fails to meet legal safety or health standards, follow these steps:

• Write to your landlord detailing the specific problems and request repairs (keep a copy).
• If unresolved, contact your local town or city health officer. You can find your health officer's contact using the official New Hampshire Health Officer Directory.
• If hazards continue, you may seek support from the state's Consumer Protection Bureau or small claims court.

Required Official Forms for Tenants

While renting a basement apartment, you may need these official forms:

• Notice to Quit Form (RSA 540:3)
  This form is used by a landlord to notify a tenant of lease termination or eviction. As a tenant, if you receive this notice, carefully review the details. Example: If your landlord claims you violated a lease term, they must specify it in the "Notice to Quit," giving you an opportunity to remedy or prepare.
  Official Notice to Quit Form (NH District Division, EV-3)
• Petition for Landlord-Tenant Writ (District Division, Form NHJB-2340-DP)
  Used in court by landlords to request formal eviction. Tenants can review or respond with the court if formally challenged. Example: If you're summoned to court, you'll see reference to this petition.
