Zoning, building permits and septic rules in Hampton borough, New Jersey

The Borough of Hampton in Hunterdon County, New Jersey has its own zoning, and a zoning permit from the borough's zoning officer is required before anyone erects or alters a structure1. Building permits follow New Jersey's Uniform Construction Code and come from a municipal construction office, not the county2. Septic permits for new construction go through Hunterdon County Environmental Health3.

Does Hampton, NJ have zoning, and what does it mean for RVs, tiny homes and lot size?

Yes. The Borough of Hampton adopts and enforces its own zoning in Article IV of Chapter 157, its Land Development Ordinance4. The borough is divided into 13 zones6, and lot sizes and building limits differ by zone. For example, the IC industrial and commercial zone calls for a one-acre minimum lot10, and the light industry zone calls for five-acre lots11. Look up the district for your parcel on the zoning map kept at the borough offices before you rely on any number.

House trailers, meaning movable homes designed for year-round occupancy, are restricted to approved trailer parks inside Hampton, and existing ones cannot be re-established elsewhere if moved7. Recreational vehicles and tiny homes are not addressed in the zoning text we reviewed, so we could not confirm whether you can live in either; ask the borough zoning officer before buying. No portion of an accessory structure may be used for living quarters8, and an accessory building outside a farming operation is capped at 15 feet tall12.

Do you need a building permit in Hampton, NJ, and who issues it?

Yes, two approvals come into play. The borough zoning officer issues a zoning permit before any structure is erected, altered or converted13. Separately, New Jersey's Uniform Construction Code requires a construction permit for new construction, additions and most improvements, and municipal construction officials issue it, not the county2. Statewide, no building permit may issue until all required state, county and local approvals are in place14.

The borough's zoning officer reports to the construction code officials13, so the two offices work together. We could not confirm the contact details of Hampton's construction office; ask the Borough of Hampton clerk's office, which can direct you.

The lot must also abut a street that gives access to the building before a permit issues15. A driveway onto a state highway needs a separate NJDOT access permit16.

How do septic permits work inside Hampton?

Hunterdon County Environmental Health, part of the Hunterdon County Health Department, performs septic design review, installation inspections and certification of completed systems5. The county provides an application for a permit to construct, alter or repair a septic system, and the health department must approve the septic plan before a building permit is issued3. State law also bars any building permit until the board of health certifies the water supply and sewerage facilities17, and the system cannot be covered until it has been inspected18.

Call19 early. Whether Hampton's own septic ordinance adds standards beyond the state's is something we could not confirm.

Building a home in Hampton: the steps, in order

  1. Find your zoning district on the zoning map at the borough offices and read the rules for that zone6.
  2. Confirm the lot abuts a qualifying street15.
  3. Get septic design approval from Hunterdon County Environmental Health3.
  4. Obtain the zoning permit from the borough zoning officer13.
  5. Apply for the construction permit with the borough's construction office2.
  6. Schedule the periodic inspections the Uniform Construction Code requires, such as footings, rough plumbing and electrical, and framing20.
  7. Close out with a certificate of occupancy, which requires a septic certificate of compliance for buildings on septic21.

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

Septic permits and inspections stay with Hunterdon County Environmental Health5, and subdivision plans are reviewed by the county before local approval22. New Jersey has no statewide owner-builder exemption from permits; a person building a home for personal use is exempt only from builder registration23, and the owner must file an affidavit with the construction official before a certificate of occupancy9.

Hunterdon County's typical home value is about $644,39624 and its effective property tax rate is about 2%25. Only 9.8% of county soils are rated not limited for a conventional septic drain field26, so expect a site evaluation and possibly an engineered system. For land outside the borough, see the Hunterdon County page.

Watch-outs

  • Subdividing in Hampton means each new lot must meet the borough's lot schedules, and flag lots need a 50-foot access strip27.
  • Farming is allowed in the RR-5 and RR-2 zones only if the landowner qualifies for farmland assessment, and that is a zoning allowance, not a permit exemption28.
  • Setbacks, lot sizes and minimum home sizes are set district by district in New Jersey's municipal ordinances29, and we could not confirm Hampton's figures, permit fees, flood-area rules or short-term rental rules; ask the borough zoning officer and construction office before you commit.
