We could not confirm which office issues septic permits inside Fanwood; the Westfield Regional Board of Health is the borough's health authority4.

Do you need a building permit in Fanwood, NJ, and who issues it?
Yes. Inside the Borough of Fanwood, no work covered by the Uniform Construction Code may begin until the Construction Official grants a construction permit1. Each building or structure needs its own application, and fees are due before the permit is issued1.
The borough's Construction Office takes applications by mail, in person or in its dropbox at borough hall10. A complete application is reviewed within 20 business days; if the borough misses that deadline, the applicant may appeal to the County Construction Board of Appeals11. Ordinary maintenance and routine repair do not need a permit12.
A certificate of occupancy is required before the building is used, and a change in use needs a new one13.
Does Fanwood have zoning, and what does it mean for lot size, height and RVs?
Fanwood has its own zoning. The borough adopted its Land Use Ordinance as Chapter 184 of its code, and the Zoning Officer enforces it214. Union County does not zone, so the county has no say in whether a use is allowed on a Fanwood lot3.
Standards depend on the district. In the R-150 Single-Family Residence District, every lot needs at least 15,000 square feet5, and no principal building may exceed two habitable floors, with maximum height set by a table in the ordinance15.
For RVs, the borough lets the operator of a recreational vehicle apply to the Chief of Police for a permit to park it at an occupied dwelling, as the only RV there, for no longer than six weeks6. Living in an RV on a vacant lot is not what that rule covers.
We could not confirm Fanwood's rules on tiny homes, accessory dwellings or minimum dwelling size; ask the Zoning Office before buying14.
How do septic permits and wells work in Fanwood?
New Jersey law bars any municipality from issuing a building permit for a new home until the board of health having jurisdiction certifies that the water supply and sewerage facilities meet state and local standards7. A septic tank or tile field also cannot be covered until a board of health representative inspects it16.
Fanwood is a member of the Westfield Regional Board of Health4. We could not confirm from the borough's published materials which office administers septic permits or well permits inside Fanwood, or whether a given lot is on public sewer. Ask the board of health and the Construction Office before you rely on a septic system. Statewide, wells need a New Jersey DEP drilling permit, and municipal or county health officials issue the well construction permit17.
Building a home in Fanwood: the steps, in order
- Confirm the lot's zoning district and dimensional limits with the Zoning Office14.
- If you are dividing land, get subdivision approval from the borough's Board before filing any plat or deed with the county18.
- Get board of health certification of water and sewerage before the building permit can issue7.
- File the construction permit application with the Construction Office, with plans and a location survey where land-use review is needed11.
- Call for inspections as work progresses; footing, rough plumbing and electrical, and framing inspections come before finishes cover the work19.
- Obtain the certificate of occupancy before moving in13.
Owners building their own home still need the permit, and must file an owner affidavit acknowledging that the work is not covered by the New Home Warranty8.
What stays with Union County, and what to check before you buy in Fanwood
Union County does not issue building permits or zoning approvals inside Fanwood; those stay with the borough320. The County Planning Board reviews site plans and subdivisions only as they affect county roads and drainage facilities21. The county page covers the wider area: Union County.
Before you buy, ask the borough about flood-hazard rules, since Fanwood has a flood damage prevention chapter we could not review in detail10. A driveway onto a state highway needs a state access permit22. Union County's effective property tax rate is about 2%, and the median bill is about $10,001 a year923.
Watch-outs
- Fanwood's construction permit fees are set by borough ordinance, so ask the Construction Office for the current schedule rather than relying on a county or state figure24.
- Septic, well and sewer-connection rules inside Fanwood are unconfirmed; ask the board of health and Construction Office before you assume a septic system is possible on a lot7.
- The borough's RV permit covers short stays at an occupied dwelling, not living in an RV on vacant land6.
- Short-term rentals are largely a matter of municipal ordinance in New Jersey, and we could not confirm Fanwood's rule25.
