NH Carbon Monoxide & Smoke Detector Law: What Renters Need to Know

Keeping your home safe is a top priority for every renter. In New Hampshire, state laws require your landlord to provide working carbon monoxide and smoke detectors in rental units as part of their duty to maintain a safe, habitable environment. Understanding your rights and responsibilities under New Hampshire law ensures you have the protection you deserve — and helps you know what action to take if things aren't up to standard.

Understanding Carbon Monoxide and Smoke Detector Requirements in New Hampshire

New Hampshire law mandates that all rental properties must have operable smoke alarms and carbon monoxide (CO) detectors installed in accordance with state codes. Here’s what every renter should know:

• Smoke detectors must be installed in every sleeping area, outside sleeping areas, and on every level of the dwelling, including basements.
• Carbon monoxide detectors are required on every level with a sleeping area or where fuel-burning appliances are present.
• Landlords are responsible for the initial installation and ensuring the devices meet local and state codes at the beginning of your tenancy.
• Renters are expected to test alarms regularly, replace batteries if needed, and notify the landlord promptly if a device malfunctions or needs replacement.

What If Your Detector Is Missing or Not Working?

If your apartment doesn’t have the required detectors, or if they’re malfunctioning and your landlord is not responding, it’s important to know your options. Under NH RSA 153:40-a and RSA 48-A:14, your landlord must maintain your rental in compliance with health and safety standards, including detector laws.

• Notify your landlord in writing about the missing, defective, or expired detector. Keep a copy for your records.
• If the issue isn’t addressed promptly, you can contact your local code enforcement office or fire department for an inspection.
• For serious unresolved violations, tenants may file a formal complaint under New Hampshire’s landlord-tenant laws.

Relevant Official Forms and Reporting Issues

• NH Code Enforcement Complaint Form
  • When to use: If your landlord fails to address life safety issues including missing detectors after you have notified them in writing.
  • How to use: Complete the form, describe the problem (e.g., "smoke detector missing in bedroom"), and submit it to your local municipality's code enforcement officer. Find this form on your city or town's official website.
  • Example: If you’ve emailed your landlord about a beeping smoke alarm and nothing happens after several days, file a code complaint with your town hall. For sample forms and contact links, see the NH Municipal Directory.
• Residential Landlord and Tenant Petition (NH Circuit Court, District Division, Landlord & Tenant)
  • When to use: If serious safety code violations remain unresolved and your health is at risk, you may petition the court for relief.
  • How to use: See the official NH Circuit Court landlord-tenant section for forms and instructions. Outline the safety issue (e.g., non-working carbon monoxide detector) with evidence and copies of prior communications.

The NH Circuit Court, District Division (Landlord & Tenant) handles housing disputes relating to maintenance, health and safety, and noncompliance with state rental laws.

State Law: Health and Safety, Dwellings, and Rental Obligations

New Hampshire rental property health and safety including detector rules are set by the NH Revised Statutes Annotated (RSA), especially RSA 153:40-a (Smoke & Carbon Monoxide Alarms in Rentals) and RSA 48-A:14 (Landlord Responsibilities).

Landlords who fail to comply may face fines, orders for repairs, or court action. Renters cannot legally remove, disconnect, or otherwise render these alarms inoperable.

How to Address Health & Safety Issues with Your Landlord

• Communicate in writing — describe the problem, request repairs, and keep a copy.
• If no response in a reasonable time, escalate by contacting municipal code enforcement.
• For unresolved health or habitability faults, consider filing a petition in court.

Many issues are resolved through written communication or local code enforcement. Formal complaints are usually a last resort.

FAQs: Carbon Monoxide and Smoke Detectors in New Hampshire Rentals
