Short answer: Before you can sell a one- or two-family home in New Jersey, your town’s fire official must inspect it and issue a smoke cert. The inspection checks smoke alarms, carbon monoxide alarms and a portable fire extinguisher. Apply early, because fees go up the closer you get to closing.
What the inspector checks
- Smoke alarms on every level and outside sleeping areas, with the type required depending on when the home was built.
- Sealed 10-year batteries. Battery-only smoke alarms must be sealed 10-year units. Hardwired alarms cannot be swapped for battery-only ones.
- Alarm age. Since March 1, 2025, no smoke alarm may be more than 10 years past its manufacture date.
- Carbon monoxide alarms where required, such as homes with fuel-burning appliances or an attached garage.
- A fire extinguisher rated at least 2A-10B:C, no more than 10 pounds, mounted within 10 feet of the kitchen on an exit path, with its top no more than 5 feet up. It must be serviced and tagged within 12 months, or new with a receipt.
Fees and timing
Fees are set by your town and rise the later you apply. For example, Bedminster charges $50 when you apply more than 10 business days before closing, $85 at 4 to 10 days and $135 at fewer than 4 days. Check your own town’s fire official for exact fees and scheduling.
How to pass the first time
- Check the date printed on the back of every smoke alarm and replace any older than 10 years.
- Replace any battery-only alarm that is not a sealed 10-year model.
- Buy and mount a compliant extinguisher, and keep the receipt.
- Test every alarm the day before the inspection.
Smoke cert vs. a resale certificate of occupancy
The smoke cert is required statewide. Some towns also require their own resale inspection or certificate of occupancy, with different rules from town to town. Ask your agent or town clerk early so neither one delays closing.
