A smoke detector lease addendum is a document added to a lease to set the terms for the unit’s smoke detector. It establishes that the unit is equipped with a working detector and outlines the tenant’s duties, such as keeping it in good condition, allowing the landlord to inspect it when necessary, and reimbursing the landlord for missing or damaged detectors when moving out. The addendum also states that the tenant should notify the landlord of any defective detectors so they can be replaced.

Frequently Asked Questions

How many smoke/carbon monoxide detectors do I need by law?

The requirements for smoke/CO detectors in homes vary by state. In general, every state requires all residential dwellings to be equipped with smoke detectors. Some states require that detectors be interconnected or hardwired with a battery backup.

Many state and local municipalities have also adopted the NFPA 72 code, which requires smoke detectors to be installed on every level of a home (including basements), inside every bedroom, and outside every sleeping area (larger homes require additional smoke detectors).
