Does Kingwood Township, NJ have zoning, and what does it mean for RVs and lot size?

Yes. Kingwood Township divides its land into 12 zoning districts and three affordable housing subdistricts under Chapter 1321. The districts include AR-2 agricultural and single-family residential, village residential VR-1 and VR-2, village commercial, business park, highway commercial, floodplain, and a scenic corridor overlay9. Which district your parcel sits in decides everything else, so start with the township zoning map.

In the AR-2 district, travel trailers, vacation trailers and campers may be parked only in rear and side yards and may not be used as living quarters, temporary or permanent4. Rules for other districts, tiny homes and temporary camping were not confirmed; ask the Zoning Officer before you plan on any of them.

For the VR-1 village residential district, the township's area and yard table appears to require a detached dwelling lot of at least 43,560 square feet with 150 feet of frontage10. Yards listed there are 25 feet front, 40 feet rear and 20 feet on each side, with lot coverage capped at 40% and principal-building coverage at 20%1112. In AR-2, principal buildings may be up to 35 feet and 2.5 stories, and barns may reach 55 feet7. The agricultural district's minimum lot size was not confirmed; ask the Zoning Officer.

Do you need a building permit in Kingwood Township, and who issues it?

Yes. New Jersey's Uniform Construction Code makes it unlawful to construct, enlarge or alter a structure without first applying to the construction official and obtaining a permit5. Inside Kingwood Township, the Kingwood Township Construction Department is the local enforcing agency2. No county building department issues these permits, and Hunterdon County states that construction in the county is subject to the state code, enforced by local officials13.

New Jersey's rules also say no permit may issue until all required state, county and local approvals are in place14. For a new home in Kingwood, that means zoning approval and the septic sign-off described below come first. Permit fees and the township's permit checklist were not confirmed; call the Construction Department at 908-996-427615.

How do septic permits work in Kingwood Township?

Septic permits in Hunterdon County are handled by Hunterdon County Environmental Health, which performs design review, site and installation inspections and certification of completed systems16. A permit is required to construct, alter or repair an individual subsurface sewage disposal system, and the health department must certify or approve the septic plan before a building construction permit is issued3. We could not confirm whether Kingwood's own Board of Health adds anything under its township sewage-disposal chapter, so ask the county office at 908-788-135117.

The AR-2 district's lot sizes exist because public water and sewer are lacking, with no plan to provide them, so new homes there rely on a private well and septic system8. Across Hunterdon County, only about 9.8% of soils rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system18. Private well permit rules inside the township were not confirmed.

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

  1. Find your parcel's zoning district on the township zoning map and read the Chapter 132 standards for it9.
  2. Get the septic design reviewed by Hunterdon County Environmental Health; the plan must be certified or approved before a building construction permit issues3.
  3. Apply to the Kingwood Township Construction Department for the building permit2.
  4. Schedule inspections at the required stages, such as footing trenches, rough plumbing and electrical, and framing before it is covered19.
  5. Obtain a health-department certificate of compliance for the septic system, then the certificate of occupancy20.

If you build your own home, New Jersey requires an owner affidavit filed with the construction official before a certificate of occupancy can issue6.

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

Hunterdon County handles septic permits for the township3, and county review of a subdivision comes before local municipal approval21. Subdivision rules inside Kingwood itself, floodplain rules, driveway rules and farm exemptions were not confirmed, so ask the township before buying a parcel you plan to split or build near a stream.

Budget for taxes: Hunterdon County's effective property tax rate is 2% and the median bill is $10,001 a year2223. Typical home insurance runs about $1,681 a year24. For land outside Kingwood, see the Hunterdon County page.
