Do you need a building permit in Florham Park, NJ?

Yes. New Jersey law makes it unlawful to construct, enlarge, repair, renovate, alter or demolish a structure, or change its use, without a permit under the Uniform Construction Code1. Florham Park has adopted the State Uniform Construction Act in its own code11, and the Borough's Building / Code Enforcement office accepts applications for building permits, including zoning applications, at its window and by mail2.

A new home also needs a certificate of occupancy before anyone moves in12. Borough permit fees are set in a fee schedule attached to the construction-code chapter13; ask the office for current amounts.

Who issues building permits in Florham Park, and how do you reach them?

The Borough of Florham Park issues its own building permits; Morris County does not14. The Building / Code Enforcement office is at 111 Ridgedale Avenue, Second Floor, and takes permit questions at 973-410-53502. Zoning applications go to the same window2.

A single-family owner who lives in the home and does the work can sign as the exempt applicant on the state permit form9. We could not confirm Florham Park's own owner-builder procedure, so ask the Building office before you file.

Does Florham Park have zoning, and what does it mean for lot size and setbacks?

Yes. Florham Park's zoning chapter is one of the Borough's land use ordinances under the Municipal Land Use Law3, and it enumerates residential, business, office, manufacturing, multifamily, open-space and mixed-use zones on a published zoning map15. Morris County has no power to zone, so the Borough alone decides4.

Rules differ by district. In the R-15 residence zone, single-family lots need at least 15,000 square feet and 100 feet of width, plus 25 more feet of width on a corner lot6. Principal buildings in R-15 need setbacks of at least 40 feet in front, 10 feet on the sides and 50 feet in the rear7. Subdivisions and site plans go through the Borough's separate subdivision chapter16.

We could not confirm Florham Park's rules for RV parking or occupancy, tiny homes or accessory apartments. Ask the Borough zoning officer through the Building office2.

How do septic permits work in Florham Park?

New Jersey bars any municipality from issuing a building permit for a building that needs sewerage facilities until the septic plan is approved8, and septic systems must be inspected before they are covered17. Local public health departments oversee single-family septic systems under 2,000 gallons per day18.

Florham Park is not among the six municipalities the Morris County Division of Public Health serves for septic permits19. We could not confirm which agency handles septic permits inside the borough, and the Borough's own code has a sewage-disposal chapter. Call the Borough's Public Health office at 973-410-53195.

The Borough also operates a sewer utility, so many addresses may connect to public sewer instead; we could not confirm which lots are in the sewer service area.

Can you live in an RV or tiny home on your land in Florham Park?

We could not confirm it. The Borough's zoning code has a provision on parking or storage of recreational vehicles, but we did not confirm its restrictions, and we found no confirmed rule on living in an RV or tiny home. Ask the zoning officer through the Building / Code Enforcement office before you buy or park anything2.

A tiny home built to the Uniform Construction Code is regulated like any other dwelling, and statewide, manufactured HUD homes are limited to single-family use groups20.

Building a home in Florham Park: the steps, in order

  1. Confirm the zoning district, lot size and setbacks with the Borough zoning officer6.
  2. Settle sewer or septic: ask Public Health at 973-410-53195.
  3. If the site fronts a state highway, get a state access permit21; a driveway onto a county road needs a Morris County permit22.
  4. File the building permit and zoning application at the Building / Code Enforcement window, 973-410-53502.
  5. Schedule inspections during construction23.
  6. Obtain the certificate of occupancy, which is not granted until water, sewer, electric and gas are installed and in service24.

What to check before you buy land in Florham Park

Morris County's median property tax bill is $10,001 a year, an effective rate of 1.8%2526. The typical home value is about $717,39027, and only about 12% of county soils rate as not limited for a conventional septic drain field, so expect a site evaluation28. These figures are county-level.

For land outside the borough, the rules differ; see the Morris County page. Check flood-hazard status with the Borough's engineer's office, because the zoning chapter regulates uses in flood-hazard areas15 and we could not confirm the operative flood rules.

Watch-outs

  • Morris County's septic office serves only six municipalities, and Florham Park is not among them19; confirm who approves a septic system before you sign a contract.
  • Zoning dimensions change by district, so the R-15 numbers do not apply to every lot in Florham Park6.
  • Borough permit fee amounts, RV rules, accessory apartment rules and flood-hazard requirements were not confirmed; ask the Building / Code Enforcement office at 973-410-53502.
