Building permits, zoning and septic rules in Edison Township, New Jersey

Edison Township, New Jersey requires a construction permit for new construction, issued by the township's own Division of Construction Code Enforcement under the state Uniform Construction Code12. The township sets its own zoning through a published zoning map and district rules3. Septic approval comes from the health department having jurisdiction before a construction permit can issue4. Edison sits in Middlesex County, which does not zone5.

Do you need a building permit in Edison Township, NJ?

Yes. Edison Township enforces the New Jersey Uniform Construction Code through its own Construction Code Enforcement agency1, and the state code requires a construction permit for new construction and for work on existing buildings10. Ordinary maintenance such as routine repair is excepted10.

The township's own page says a permit is generally required to construct, enlarge, alter, or demolish a structure2. Site improvements are a separate track: applications go to the Director of Planning and Engineering's office, and if the Engineering Department does not approve or deny a complete application within 7 days, it is deemed approved11.

Who issues building permits in Edison Township, and how do you reach them?

The Edison Township Division of Construction Code Enforcement, part of the Department of Planning and Engineering, issues construction permits inside the township2. Call 732-248-7257 or visit 100 Municipal Boulevard, Edison2. This is a township office, not a Middlesex County one: the county's role in New Jersey is limited to planning review, and the statewide code is enforced by municipal officials12.

Inspectors need 24 hours advance notice and must be able to see the work being inspected2. Once work passes final inspections, the construction official issues a certificate of occupancy13.

Does Edison Township have zoning, and what does it mean for lot size and setbacks?

Yes. Edison Township's code establishes zoning districts and an official zoning map, including R-AA, R-A, R-BB and R-B residential districts3. Schedule A of the code sets area, yard, building, coverage, height and floor-area requirements district by district3, so lot size and setbacks depend on the district your parcel sits in. The Zoning Officer in the Division of Planning and Zoning enforces the zoning chapter14, and the Zoning Officer's review is the first step in the permit process2.

Middlesex County does not set zoning; New Jersey law gives that power to municipalities5. We could not confirm township rules on tiny homes, accessory dwelling units or camping on private land, so ask the Division of Planning and Zoning before planning any of them.

How do septic permits work in Edison Township?

New Jersey law bars any building permit until the board of health having jurisdiction certifies the water supply and sewerage plan15. In Edison, a building using an individual septic system needs proof of health-department approval of the septic plan before the construction permit4. The septic system must also be inspected before it is covered16.

Middlesex County's Environmental Health Division states that all septic work requires its approval; call 732-745-848017. Edison also has its own Health Department with an environmental health section, so confirm with both which office reviews your plan.

Much of Edison is sewered. Houses on properties along a township sewer in the adjoining street must connect to it6.

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

  1. Confirm the zoning district and its Schedule A requirements with the Division of Planning and Zoning314.
  2. If the lot is in a flood hazard area, apply to the Floodplain Administrator for a floodplain-development permit7.
  3. Obtain septic-plan approval where there is no sewer, or arrange a sewer connection46.
  4. Apply to the Construction Code Enforcement division with the application, plans and plot plan; the Zoning Officer reviews first2.
  5. Book inspections with 24 hours notice2.
  6. Obtain a certificate of occupancy before using the new building9.

Subdivisions go to the township Planning Board, with Middlesex County Planning Board review where state law requires it18.

What stays with Middlesex County, and what to check before you buy in Edison?

Septic approval and the county's subdivision review remain county-level, and the state sets the building code1917. For land outside Edison, see the Middlesex County page.

A person building a home for personal use is exempt from new-home builder registration, but not from permits or inspections8. An owner-built home needs an affidavit filed with the construction official before a certificate of occupancy20.

Middlesex County's effective property tax rate is21% and its median tax bill is about $9,684 a year22.

Watch-outs

  • We could not confirm Edison Township rules on private wells, tiny homes, accessory dwelling units, camping, short-term rentals, driveway access or agricultural exemptions; ask the Division of Planning and Zoning at 732-287-090014.
  • Both a township health department and the county Environmental Health Division handle health matters; confirm which one approves your septic plan before you apply for a construction permit417.
  • Building near a stream or in a flood hazard area can require a floodplain-development permit and NJDEP authorization on top of the building permit7.
