Do you need a building permit in Neptune Township, New Jersey?

Yes. Neptune Township requires construction permits, and the permit depends on what type of work you are doing1. New Jersey's Uniform Construction Code makes a permit mandatory before covered construction, alteration or demolition begins, with ordinary maintenance excepted7. The township publishes a Construction Permit Checklist, application forms and a construction portal8.

Projects are inspected at required stages by the township's building, plumbing, mechanical, fire and electrical subcode officials9. A new home also needs a certificate of occupancy from the construction official before anyone uses it10.

Who issues building permits in Neptune Township, and how do you reach them?

The Neptune Township Construction Department at 25 Neptune Blvd issues building permits inside the township, and its phone number is 732-988-520011. Monmouth County does not issue building permits; the township's construction official does12.

The county's role is narrower: the Monmouth County Development Review Committee approves subdivisions and site plans that affect county roads, drainage facilities or county-owned property13.

Does Neptune Township have zoning, and what does it mean for RVs and setbacks?

Yes. Neptune Township publishes residential, commercial, industrial, planned-unit-development, public-use and historic districts and a zoning map in its Land Development Ordinance2. Monmouth County does not zone; zoning belongs to each municipality14.

Setbacks, lot size and height differ by district, so find your parcel's district on the township zoning map before planning anything15. The Land Use office publishes the zoning map and the ordinance16.

Occupying a trailer, camp car, trailer coach or recreational vehicle as a dwelling is prohibited in Neptune Township, whether or not the lot has an occupied building4. We could not confirm any township provision on tiny homes; ask the Zoning Officer before buying.

How do septic permits work inside Neptune Township?

The Monmouth County Office of Public Health oversees septic system and well approvals and inspections for Neptune Township317. Where public sanitary sewer is not available, the township allows only a subsurface disposal system that meets township rules and state standards, with a written Health Officer permit and inspections18.

Under state law, the board of health must certify the septic and water plans before a building permit can issue19, and the system must be inspected before it is covered20.

We could not confirm the township's own well permit requirement; New Jersey requires a DEP well-drilling permit before a well is built6.

Building a home in Neptune Township: the steps, in order

  1. Find the parcel's zoning district on the township zoning map and confirm the use with the Zoning Officer16.
  2. If there is no public sewer, get septic and well approval from the Monmouth County Office of Public Health first, because no building permit may issue before the board of health certifies19.
  3. Obtain any required zoning or planning approvals; zoning approval must be in place before plan review for an owner-occupied one- or two-family project21.
  4. Apply to the Construction Department using the Construction Permit Checklist and forms8.
  5. Schedule the required inspections as work proceeds9.
  6. If you built the home yourself, file the owner's affidavit with the construction official before the certificate of occupancy5.

What stays with Monmouth County, and what to check before you buy

Septic and well oversight stays with the Monmouth County Office of Public Health3. Land outside the township follows the rules on the Monmouth County page. A driveway onto a New Jersey state highway needs a state access permit22.

Before you buy, note that Monmouth County's soil data rates 0% of its soils as not limited for a conventional septic drain field, so expect a site evaluation or an engineered system23. Monmouth County's effective property tax rate is 1.8%24. Neptune's floodplain rules also require a floodplain development permit inside special flood hazard areas11.

Watch-outs

  • Short-term rentals in Neptune Township need a Short Term Rental Application through Code Enforcement, with separate winter and summer periods25.
  • We could not confirm any township rule on tiny homes or agricultural exemptions; ask the Zoning Officer through the Land Use office before relying on either16.
  • A construction permit is needed even for work such as water-heater or furnace replacement done by the homeowner1.
