Does Millstone Township, NJ have zoning?

Yes. Millstone Township divides its land into zoning districts and regulates buildings, structures and land uses in them through Chapter 35, Land Use and Development Regulations1. The Township's zoning map, adopted May 21, 2003, shows where each district's boundaries fall5. Monmouth County does not zone: in New Jersey the county has no authority to adopt zoning for unincorporated areas, and zoning is a municipal job11.

Rules differ by district, so find your parcel's district on the zoning map or ask the Zoning Officer before you buy6. We could not confirm the Township's rules on RVs, tiny homes or manufactured homes; ask the Zoning Officer, because New Jersey leaves those questions to each municipality's district standards.

What are the lot size and setback rules in Millstone Township?

In the R-80 Rural Residential zone, the minimum lot area is 80,000 square feet, but major subdivision lots approved after June 21, 2000 need 2 acres7. Single-family homes in R-80 need a 50-foot front setback, 30-foot side yards with 60 feet combined, and a 50-foot rear setback12. Maximum lot coverage in R-80 is 20%13, and maximum building height is 35 feet and 2 stories14.

In the R-170 Rural Environmental zone, the minimum lot area is 170,000 square feet, and 4 acres for major subdivision lots approved after June 21, 20008.

Preserved farmland and Green Acres land can be different: where farms are a permitted use, a preserved tract may be allowed to subdivide one fully conforming lot for a single-family home under R-80 requirements15.

Do you need a building permit in Millstone Township?

Yes. New Jersey's Uniform Construction Code requires a construction permit for building, enlarging, altering, renovating or demolishing a structure, and installing regulated equipment2. Millstone Township's own Construction Department handles review and inspections, with building, electrical, plumbing and fire protection subcode officials3. The county does not issue building permits16.

A zoning permit comes first or at the same time: the Township requires one before any building permit or certificate of occupancy is issued6. A new building also needs a certificate of occupancy17. We could not confirm the Township's permit fee schedule; ask the Construction Department.

How do septic permits work in Millstone Township?

New Jersey requires approval and inspection before covering a septic system for a new home on realty improvements1819. In Millstone Township, the Township itself does not run that review: it contracts with the Monmouth County board of health for health services4. The Monmouth County Office of Public Health says it oversees septic approvals and inspections for its member municipalities20.

We could not confirm the exact septic permit steps for Millstone Township, so call the number listed for the Board of Health before you design a system4. Wells are a state matter: New Jersey requires a permit for drilling a private or residential well21. Millstone Township says all of its homes use well water3.

Can you build your own home in Millstone Township?

An owner can build their own home, with conditions. New Jersey exempts a person constructing a new home for personal use and occupancy from new-home builder registration9. The exemption does not skip the construction permit22. A certificate of occupancy for an owner-built home requires an affidavit to the construction official that all work conformed to applicable law10.

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

  1. Find the parcel's zoning district on the Township zoning map and read that district's lot, setback and coverage rules5.
  2. Apply for a zoning permit with the Zoning Officer, with a survey showing setbacks6.
  3. Get septic approval through the Monmouth County board of health arrangement and a state well permit421.
  4. Apply for construction permits with the Construction Department3.
  5. Request inspections at each stage, then obtain the certificate of occupancy23.

What stays with Monmouth County and the state?

Monmouth County's Development Review Committee approves subdivisions and site plans that affect county roads, drainage facilities or county property24. A driveway onto a county road may need county review25, and a driveway onto a state highway needs a state permit26. For land outside Millstone Township, see the Monmouth County page.

Watch-outs

  • Septic permitting runs through the Monmouth County board of health, not the Township's construction office, so call before you assume a lot will perk4.
  • Lot sizes differ by district and by when a subdivision was approved, so confirm the district and any post-2000 subdivision rule with the Zoning Officer7.
  • Monmouth County's effective property tax rate is 1.8%27.
