Does North Caldwell, New Jersey have zoning?

Yes. The Borough of North Caldwell divides its land into zoning districts under Chapter 107, "Zoning and Land Use," and the borough's zoning map is dated September 6, 202415. Essex County does not zone; New Jersey counties have no zoning grant under the Municipal Land Use Law, so the borough's code is the one that applies to a parcel here9.

The borough's zoning officer supervises building activity to ensure compliance with Chapter 10710. Setbacks, height limits and lot coverage are set district by district, so you need the parcel's district before you can answer them11. We could not confirm the main single-family setback and height schedule; ask the zoning officer.

Lot size depends on the district too. In the R-1 Residential Cluster District, the code states a gross density of 30,000 square feet and a minimum lot size of 15,000 square feet, subject to site-plan review and approval12.

Do you need a building permit in North Caldwell, and who issues it?

North Caldwell has its own Construction Department, led by a Construction Official / Building Inspector2. New Jersey's Uniform Construction Code requires a construction permit before you construct, enlarge, repair, alter or demolish a structure, and ordinary maintenance is the main exception4.

Zoning approval comes first for an owner-occupied one- or two-family addition or alteration: no plan review proceeds until zoning approval is in place13. Before a new dwelling in the R-1, R-2 or cluster districts gets a building permit, the code requires provisions for a garage connected by a driveway to the street14.

Fees are set by the borough, and we could not confirm the current schedule; call the Construction Department for it15.

How do septic permits work in North Caldwell?

Septic permits inside North Caldwell come from the borough, not the county. The borough code says an individual subsurface sewage disposal system permit is issued by the Health Officer or the Health Officer's designee, and no one may install, construct, alter or repair a system before the permit36.

New Jersey law adds that the board of health must certify the sewerage facilities before a building permit can issue, and a septic system may not be covered until the board of health's representative inspects it1617. Where public sewer is not available, the borough's sewer code requires an individual facility with separate septic permits and Health Officer approval18.

Soils are a real constraint: only about 2% of Essex County soils rate "not limited" for a conventional drain field, so expect a site evaluation and possibly an engineered system19. Call the borough Health Department at 973-226-230320.

Can you live in an RV or tiny home in North Caldwell?

We could not confirm a rule for RV occupancy, tiny homes or temporary camping in North Caldwell; the borough's zoning code is where the answer sits, and its operative text on these uses was not confirmed. Do not assume a use is allowed because no rule is listed.

What the borough does set is a minimum house size: in the R-1 Residence District, a one-story dwelling needs at least 1,600 square feet of living floor space7. Ask the zoning officer10 in writing about your district before buying.

Building a home in North Caldwell: the steps, in order

  1. Confirm the parcel's zoning district and dimensional rules with the zoning officer10.
  2. If you are creating a new lot, expect subdivision review21.
  3. Get septic approval from the borough Health Officer where no public sewer serves the lot6.
  4. File the construction permit application with the Construction Department2.
  5. Schedule the state-required inspections at footing, rough plumbing and electrical, and framing stages22.
  6. If you built the home yourself, file the state owner-builder affidavit before the certificate of occupancy8.
  7. Obtain the certificate of occupancy; any site-plan approval needs final Planning Board sign-off first23.

What stays with Essex County and the state, and what to check before you buy

Essex County's land-use page for the rest of the county is at Essex County. The county does not set zoning; zoning is municipal24.

Private wells need a state drilling permit, with the municipal or county health officials issuing the well construction permit25. Any driveway onto a State highway needs a state access permit26.

On cost, Essex County's median property tax bill is $10,001 a year and the effective rate is 2%2728; the typical home value is about $675,06529. These are county figures, not North Caldwell's alone.

Watch-outs

  • Single-family setbacks, height limits and floodplain permit rules in North Caldwell were not confirmed; ask the zoning officer before you design10.
  • Whether an owner-builder exemption exists beyond the state affidavit was not confirmed; permits and inspections still apply8.
  • Well rules specific to the borough were not confirmed; the state requires a drilling permit25.
