New Hampshire smoke and carbon monoxide detector rules: both devices in rentals and a written notice before a citation
RSA 153:10-a requires automatic fire warning devices and carbon monoxide detection devices in multi-unit dwellings and rental units in New Hampshire, and makes the owner of a rental unit responsible for keeping them in a suitable condition. Enforcement starts with a written notice of violation and a time to fix the problem.
Which buildings need which devices?
Multi-unit dwellings and rental units must have both automatic fire warning devices and carbon monoxide detection devices. Single-family dwellings built or substantially rehabilitated after January 1, 2010 must have both. The devices must meet standards the statute cites: NFPA 72 and NFPA 101 for fire warning devices, and NFPA 720 for carbon monoxide detectors.
CO detectors are not required if the unit has no attached garage and no fuel-burning appliance or device. One is required once a garage or such an appliance is added later. The statute uses the term "automatic fire warning devices" rather than "smoke detector."
What is the owner's duty?
The owner of a rental unit is responsible for keeping the fire warning and carbon monoxide devices "in a suitable condition." The text I read does not say who installs the devices, does not mention batteries or power sources, and assigns no duties to tenants. That leaves a practical rule: because the owner answers for condition, the owner should arrange testing, replace what fails and keep the record.
Example a made-up owner in Nashua adds a gas water heater to a unit that had no fuel-burning appliance before. The CO exemption no longer applies, so the owner installs a CO detector before the tenant uses the new appliance.
How is it enforced?
The enforcement authority must issue a written notice of violation with a time limit to fix the problem, served by certified mail or in person. Local fire authorities may be authorized in writing to issue citations, which carry the penalty in RSA 153:24 (not included in the text I read). A party aggrieved by the state fire marshal's decision may appeal to the supreme court within 45 days of notice.
Where New Hampshire owners slip
The usual slip is treating the CO exemption as permanent. A unit with no garage and no fuel-burning appliance may skip CO detection, but a later addition, such as a gas dryer, a space heater that burns fuel or a garage conversion, changes the answer. Track the appliances in each unit. Another slip is responding to a notice of violation after the time limit in it has run. Put the date from the notice on the calendar the day it arrives, fix the device, and keep proof of the fix, such as an invoice and a photo of the working device.
Keeping an appliance log
A simple log solves most New Hampshire questions. For each unit, list the fuel-burning appliances, whether there is an attached garage, the type and location of each fire warning and CO device, and the test dates. When the unit changes, update the log the same day. If an official asks about a unit, the log answers in minutes, and if a notice of violation arrives, you know exactly what the unit has and what is missing. The log costs little to keep and supports the owner's responsibility for suitable condition.
How DoorKeeping fits in New Hampshire
DoorKeeping keeps a New Hampshire unit's alarm checks as dated work orders with photos, so the move-in test, the tenant's reports and your fixes are on the record. Each unit's appliances can be listed on its record, so a new fuel-burning item prompts a detector check. This is general information, not legal advice. Check the current statute, your local fire code and your lease before you act.
