NJ Resale Certificates: CO/CCO and the Smoke & CO Certificate

Two inspections commonly hold up NJ closings: the town’s resale certificate and the fire-safety certificate. Order both early.

Smoke, CO and fire extinguisher certificate

New Jersey requires a Certificate of Smoke Detector, Carbon Monoxide Alarm and Portable Fire Extinguisher Compliance before a one- or two-family home is sold or leased to new occupants. It is issued by the local fire official or enforcing agency. Requirements include alarm placement and a properly mounted extinguisher. Check your town’s rules.

Municipal resale CO or CCO

Many towns require their own resale inspection, often called a Certificate of Occupancy or Certificate of Continued Occupancy. What they inspect varies widely. Some focus on safety items, others look at zoning, permits and exterior conditions.

Open permits can delay you

Unpermitted finished basements, decks or additions can surface during resale inspections or the buyer’s title search. Your attorney can advise on closing open permits.

Timing

Schedule inspections as soon as you list. Fees and wait times vary by town.
