If you are selling a house in East Brunswick, you will hear about two documents that sound alike: a smoke and carbon monoxide alarm certificate, and a certificate of occupancy. They do different jobs, and for most home sales in East Brunswick only one of them applies. This guide explains which one you need, what the inspection checks, and when to book it so it does not hold up your closing.
If you are just starting to plan a sale, our seller guide covers pricing and preparation from the beginning.
What is the smoke and CO alarm certificate?
New Jersey law requires the owner of a one- or two-family home, or an attached single-family home such as a townhouse, to obtain a certificate of smoke alarm and carbon monoxide alarm compliance before the home is sold, leased or otherwise changes occupancy for residential purposes. The rule is N.J.A.C. 5:70-2.3, and an owner who sells without the certificate can be fined up to $500. In East Brunswick the certificate comes from your fire district’s fire prevention office after an inspection.
Under the state fire code (N.J.A.C. 5:70-4.19), the home needs:
- A smoke alarm on each level and outside each separate sleeping area.
- A carbon monoxide alarm in the immediate vicinity of the sleeping areas, unless the home has no fuel-burning device and no attached garage.
- The right type of smoke alarm. Battery-powered units must be ten-year sealed units. Hardwired alarms installed in the original construction must not be replaced with battery units.
The certificate cannot be transferred. If the sale or move-in does not happen within six months of the application, the state rule requires a new application.
What do East Brunswick’s fire offices look for?
East Brunswick Fire District 2 publishes year-built criteria for one- and two-family homes on its smoke and CO application. Every row also requires a CO alarm within 10 feet of each sleeping area.
| Home built | Smoke alarms District 2 lists |
|---|---|
| Before 1977 | Ten-year sealed battery alarms, one on each level and within 10 feet of each bedroom |
| After 1977, before 1984 | Electric alarms, not interconnected, one on each level and within 10 feet of each bedroom |
| After 1984, before 1990 | Electric alarms, interconnected, one on each level and within 10 feet of each bedroom |
| After 1990 to present | Electric alarms with battery backup, all interconnected, one on each level, within 10 feet of each bedroom and in each bedroom |
The District 1 and 3 request page does not list criteria, so call that office if you are unsure how your home will be measured.
Do I still need a fire extinguisher to sell?
No, not for the certificate. A state law signed on February 3, 2025 (P.L. 2025, c. 19) removed the portable fire extinguisher requirement for one- and two-family homes. District 2’s application now lists an extinguisher as recommended rather than required. The same law added a labeling rule. If the home has a secondary power source, such as a permanent generator, solar panels or battery storage, a label warning of the danger of secondary power sources must be installed within 18 inches of the main electrical panel and the electrical meter.
What is a certificate of occupancy?
A certificate of occupancy is a construction code approval that says a building may legally be occupied. New construction gets one before anyone moves in, and some New Jersey towns also require a new one at every resale.
East Brunswick is not one of those towns for homes. The township’s Construction Office states that, by ordinance, East Brunswick does not require or issue a certificate of occupancy for residential resales or rentals. Once a home has its original certificate, it is only inspected again when improvements or changes are made, and then only those improvements are inspected.
Which applies to my East Brunswick sale?
For a typical house, townhouse or two-family home in East Brunswick:
| Document | Needed for a residential resale in East Brunswick? | Who issues it |
|---|---|---|
| Smoke and CO alarm certificate | Yes, before closing | Your fire district’s fire prevention office |
| Certificate of occupancy | No, unless open permits or new work call for one | East Brunswick Construction Office |
Two situations can change this. If a basement was finished, a deck was added or other permitted work was done, make sure those permits were closed out with final inspections. And a home that needs enough rehabilitation to require a new certificate of occupancy is handled differently under state law, so talk with your attorney.
Commercial property follows different rules. The township code (Chapter 75, as amended by Ordinance 24-06 on May 13, 2024) calls for an application for a resale or new tenant certificate of occupancy on a change of owner or tenant outside the Residential R-5 group of one- and two-family homes, with a $75 processing fee and a $200 permit fee. The same code says a certificate of continued occupancy can be provided on request, and the Construction Office page words the rule differently. Which certificate and inspections apply depends on the property and the change, so commercial owners and buyers should confirm with the East Brunswick Construction Office at 732-390-6875 before setting a closing or lease date.
How do I find my fire district?
East Brunswick has three fire districts. The township posts a fire districts map you can check against your address. As of November 11, 2026, residential smoke and CO inspections are handled by two offices:
- Districts 1 and 3: Bureau of Fire Safety, 680 Old Bridge Turnpike, 732-651-8806. Requests are made through the District 1 and 3 smoke and CO request page.
- District 2: Fire Prevention Bureau, 216 Joseph Street, 732-210-4582, open Monday to Friday, 9:00 AM to 4:00 PM. The application is on the District 2 fire prevention forms page.
If you are unsure which district you are in, call either office and give them the address.
When should I request the inspection, and what does it cost?
The District 1 and 3 office asks for requests at least two weeks before the closing or rental date. District 2 inspects on Monday, Wednesday and Friday between 4:00 and 6:00 PM, and says it issues the certificate right away once an inspection is compliant. Both applications ask for the closing or rental date, so apply once it is set. Fees follow the township code (Chapter 102, section 102-14) and match both offices’ published fees:
| When the inspection is requested | Fee |
|---|---|
| More than 10 business days before the change of occupant | $50 |
| 4 to 10 business days before | $75 |
| Fewer than 4 business days before | $125 |
A $20 fee applies to each reinspection after a failed inspection, and a $75 fee applies if no one is present at the scheduled time. The District 1 and 3 page words its tiers in days, while the code and District 2 use business days, so confirm how your request will be counted, and check fees when you apply.
How do I get ready for the inspection?
- Test every alarm. District 2 asks owners to do this before the inspection.
- Confirm there is a smoke alarm on every level, including the basement, and outside each sleeping area, and a CO alarm within 10 feet of the bedroom doors.
- Have the year built and the year of any renovation ready. The District 2 application asks for both.
- If the home has solar panels, a generator or battery storage, confirm the warning label is in place.
- Arrange for someone to be there, since a missed appointment costs $75.
What else should East Brunswick sellers prepare before closing?
The certificate is one item on a longer list. Others that apply to New Jersey sellers:
- The seller’s property condition disclosure. Residential sellers must answer the state’s disclosure statement, including the flood risk questions, before the buyer becomes obligated under a contract. The New Jersey flood disclosure page explains the flood questions and links to a lookup tool.
- Open permits. Ask the Construction Office whether any permits on the property are still open.
- Attorney review. New Jersey contracts for one- to four-family homes include a three business day attorney review period. Your attorney also coordinates many closing documents, so ask early what they need from you.
Plan your sale with the paperwork in mind
Booking the smoke and CO inspection once your closing date is set removes one item from the final weeks. If you are thinking about selling in East Brunswick, you can start with a home valuation request.
