New Hampshire Smoke Alarm Rules: Tenant Duties & Landlord Duties

Smoke alarms are a critical part of apartment safety in New Hampshire. As a renter, it's important to know both your own responsibilities and what your landlord must provide under state law to keep your household safe. This article explains who installs, tests, and maintains smoke alarms, which laws apply, and what to do if you notice a problem – plus official resources to help you protect your rights and safety.

Understanding Smoke Alarm Requirements in New Hampshire Rentals

New Hampshire requires working smoke alarms in all residential rental units. Both landlords and tenants have important roles to keep these devices active and functioning. Requirements and duties are set out in the New Hampshire State Fire Code and further discussed in state rental housing law.

Landlord Responsibilities

New Hampshire landlords are responsible for:

  • Installing required smoke alarms on every level of the rental unit and near sleeping areas
  • Ensuring that alarms are working and properly placed before a new tenant moves in
  • Replacing smoke alarms that are no longer functional or have passed their expiration
  • Upgrading alarms to meet any changes in the law or local fire codes

Landlords must comply with the New Hampshire State Fire Marshal’s Office residential requirements and local fire officer recommendations.

Tenant Duties

As a tenant, you are expected to help maintain smoke alarm safety in your apartment by:

  • Testing smoke alarms regularly (usually monthly)
  • Replacing the batteries in battery-powered alarms as needed, unless your landlord is responsible per your lease
  • Not disabling, removing, or tampering with smoke detection devices
  • Notifying your landlord promptly if a smoke alarm malfunctions or needs replacement

If you notice a missing or broken smoke alarm or need assistance, you should contact your landlord in writing. If the landlord doesn't address the complaint, you may contact your local code enforcement officer or fire department.

Relevant Official Forms and When to Use Them

  • Notice to Landlord of Defective Condition
    If your landlord has not repaired or replaced a faulty smoke alarm after you notify them verbally, send a written Notice to Landlord of Defective Condition. This establishes a record and is required if you need further legal support. Example: A tenant notices the hallway smoke alarm is chirping, requests repair by email, and sends this notice if the landlord does not respond within a few days.
  • Tenant Petition for Relief from Hazardous Condition (No official statewide form, but used locally)
    If repairs are not made, tenants may submit a petition to their local Housing Standards Board or municipal code enforcement office. In emergency situations, you can also contact the New Hampshire State Fire Marshal for support and next steps.

Which Laws and Agencies Govern Smoke Alarms in Rentals?

If your landlord fails to install or fix a smoke alarm after written notice, you can seek help from your local code enforcement office or file a complaint with the New Hampshire Circuit Court. Always keep a copy of your written communications.
