What smoke and carbon monoxide alarm rules apply to landlords in New Jersey?
Short answer
Smoke/CO alarm compliance certificate before each new tenancy (1-2 family)
When: Before the unit is leased / before a change of occupancy (new tenant)
Before leasing a 1-2 family home to a new tenant, obtain a smoke alarm/carbon monoxide alarm compliance certificate from the local enforcing agency (or the municipal CO that replaces it).
"Before any one- and two-family or attached single family structure is sold, leased, or otherwise made subject to a change of occupancy for residential purposes, the owner shall obtain a certificate of smoke alarm, carbon monoxide alarm, and portable fire extinguisher compliance" nj.gov
"If the change of occupancy specified in the application for a CSACMAPFEC does not occur within six months, a new application shall be required." nj.gov
"When a one- or two-family dwelling undergoes a change of occupancy such as a sale or change of tenant, and a municipality requires a municipal certificate of occupancy or similar approval," nj.gov

Deadline: Before the unit is leased / before a change of occupancy (new tenant)
Before leasing a 1-2 family home to a new tenant, obtain a smoke alarm/carbon monoxide alarm compliance certificate from the local enforcing agency (or the municipal CO that replaces it).
Who it covers: One- and two-family and attached single-family structures. Where the municipality has its own certificate-of-occupancy/inspection, that replaces the state certificate but must verify alarm compliance. Certificate is not transferable; reapply if occupancy change does not occur within six months. CO alarm not required if no fuel-burning appliances and no attached garage.

Notes: N.J.A.C. 5:70-2.3 as adopted in 2018 (50 N.J.R. 729(a)); later amendments (e.g., P.L. 2025, c.19; certificate now referred to as CSACMASPSIL; portable-extinguisher element changed) mean the current text may differ—confirm current N.J.A.C. text. Statutory basis N.J.S.A. 52:27D-198.1. Confirm the current rule: these quotes come from the 2018 adoption of N.J.A.C. 5:70-2.3, which has since been amended (the certificate now has a different name and contents). Check the current N.J.A.C. text or your local fire official before relying on the details.
