Zoning, building permits and septic rules in the Borough of Cresskill, New Jersey

The Borough of Cresskill, in Bergen County, New Jersey, runs its own State Uniform Construction Code agency, so building permits for projects inside the borough come from the Cresskill Building Department1. Zoning is set by the borough's own zoning code, with one-family districts R-40, R-15 and R-102. Septic and wells are health-board matters; we could not confirm which health department covers a given Cresskill lot3.

Does Cresskill, NJ have zoning, and what does it mean for lot size and setbacks?

Yes. The Borough of Cresskill adopts its own zoning code, which includes a zoning map, a schedule of requirements and the R-40, R-15 and R-10 One-Family Residence Zones2. Bergen County itself does not zone municipal land; zoning authority stays with the municipalities12.

Dimensions depend on the district. In the R-40 zone a single-family lot needs a front yard of at least 50 feet, side yards of at least 30 feet each (60 feet in total) and a rear yard of at least 75 feet13. In R-15 the minimums are 40 feet front, 15 feet per side (35 feet total) and 50 feet rear14. In R-10 they are 25 feet front, 15 feet per side (35 feet total) and 30 feet rear15.

Minimum livable floor area per dwelling is 1,200 square feet in R-405, 1,100 in R-156 and 1,000 in R-107. Find out which district a lot sits in on the borough zoning map before making an offer.

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

Yes, for work that is regulated by the construction code. The Borough of Cresskill has its own State Uniform Construction Code enforcing agency, with a Construction Official and building, plumbing, electrical and fire protection subcode officials1. Projects that require a construction permit are not complete until final inspections are made and a certificate of occupancy or approval is issued4.

The borough's code establishes the agency that issues the permits and sets its fees16. The borough's page does not list every permit exemption, so ask the Building Department before starting small work such as sheds or fences4.

What do building permits cost in Cresskill?

Construction permit fees follow the subcode fee schedule in the borough's construction code chapter17. Starting work before getting a borough permit doubles the permit fee17. The certificate of occupancy fee is 10% of the total construction permit cost, with a minimum of $100, and is prepaid when the permit is issued17.

A construction permit is valid for one year from issuance and becomes invalid if work is suspended for six months18.

How do septic permits and wells work in Cresskill?

New Jersey law requires the board of health with jurisdiction to certify a proposed water supply and sewerage system before any building permit is issued, and construction cannot begin first9. A board of health representative must also inspect and approve a septic system before it is covered19.

Bergen County Health Services reviews septic plans and oversees installations, but only for the municipalities that contract with it, not every town in the county10. We could not confirm whether Cresskill is one of them or handles septic through its own health department; ask the Cresskill Building Department, then Bergen County Health Services at 201-634-260020. Private wells need a state well-drilling permit, with municipal or county health officials issuing the construction permit21.

Can you live in an RV or tiny home in Cresskill?

We could not confirm a Cresskill rule on living in an RV, tiny home or manufactured home, or on camping on private land. The borough zones every district itself, so the answer depends on the lot's district and on the Zoning Officer's reading of Chapter 2752. Ask the Cresskill Building Department, which also handles zoning, and get the answer in writing before buying a lot or a unit16.

What are the steps to build a home in Cresskill, in order?

  1. Identify the zoning district on the borough zoning map, then check the setbacks and minimum floor area for that district2.
  2. If the lot would be subdivided, review the borough's subdivision chapter, which sets the approving agency, classifications and application procedure22.
  3. Confirm the septic or sewer arrangement and get board of health certification before the building permit9.
  4. Apply to the Cresskill Building Department for the construction permit16.
  5. If the lot is in a flood hazard area, a separate floodplain permit is required under the borough's floodplain chapter23.
  6. Schedule the building, fire, plumbing and electrical inspections24.
  7. Obtain the certificate of occupancy before anyone moves in8.

What stays with Bergen County and the state before you buy in Cresskill?

Bergen County's rules for unincorporated land do not apply inside the borough; see the Bergen County page for county-level answers. The county does not set zoning, but it reviews subdivisions that affect a county road25. A driveway onto a State highway needs a New Jersey DOT access permit26. Septic and well oversight sit with the board of health3.

Bergen County's typical home value is about $791,00027 and its effective property tax rate is 1.7%28; these are county-level figures, not Cresskill-specific.

Watch-outs

  • Owner-builders are not exempt from permits: the state's personal-use exception covers new-home builder registration and warranty requirements, not construction permits or inspections11.
  • An owner-built new home still needs an affidavit filed with the construction official before a certificate of occupancy is issued29.
  • Starting work without a Cresskill permit doubles the permit fee17.
  • We could not confirm Cresskill's driveway permit requirements; a driveway onto a State highway needs a New Jersey DOT access permit regardless26.
  • Short-term rentals are limited by local rules in New Jersey, and we could not confirm Cresskill's; ask the Building Department before buying for rental use30.
