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

Yes. Irvington Township has established a State Uniform Construction Code Enforcing Agency, so construction inside the township is permitted and inspected locally1. New Jersey law makes it unlawful to construct, enlarge, repair, renovate, alter or demolish a structure without the required permit9. Ordinary maintenance and routine repair do not need one10. Permit fees are set by each municipality's own ordinance, so ask the township for its current schedule11.

Who issues building permits in Irvington Township?

The township's own enforcing agency, not Essex County, issues building permits and runs inspections1. The township's Division of Building Construction Inspectors is charged with inspecting buildings, plans and premises12. We could not confirm a direct line for the construction office; the township municipal building's main number, 973-399-8111, is the starting point13. The permit application must include a general description of the work and the required approvals must be in place before a permit issues14.

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

Zoning in Irvington Township is the township's own, because New Jersey municipalities, not counties, adopt zoning ordinances2. Lot size, setbacks, height and permitted uses differ by zoning district, so check the parcel's district before you buy1516. We could not confirm township rules on RV occupancy, tiny homes or accessory dwellings, so ask the township zoning office before planning any of them. An owner-occupied one- or two-family addition or alteration needs zoning approval before plan review proceeds14.

How do septic permits work in Irvington Township?

New Jersey requires sewerage facilities, including septic, to be approved before a building permit issues for a realty improvement17. Which local office administers that approval in Irvington Township is unconfirmed, so ask the township municipal building13. In practice, a building within 200 feet of the sanitary sewer must connect to it, and new buildings must connect before a certificate of occupancy5. The connection fee is $150 per equivalent dwelling unit5. Essex County's soils also rarely rate well for conventional drain fields18.

Can you live in an RV or tiny home in Irvington Township?

We could not confirm any township rule on RV occupancy, temporary camping or tiny homes in Irvington Township, so do not assume either is allowed. Ask the township zoning office, via the municipal building, before parking an RV for living or placing a tiny home. State rules limit HUD manufactured homes to single-family use groups19.

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

  1. Confirm the parcel's zoning district and rules with the township13.
  2. If you are dividing land, get subdivision or site-plan approval first; selling land before approval is prohibited8.
  3. Apply for a construction permit with the township enforcing agency1.
  4. Arrange the required inspections; the owner must give written notice at least 24 hours before each20.
  5. Owner-builders file the state affidavit before a certificate of occupancy can issue6.
  6. Obtain the certificate of occupancy after final inspections7.

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

Essex County does not zone land; the township does2. For the county's own overview, see the Essex County page. Essex County's effective property tax rate is about 2%21 and the median property tax bill is about $10,001 a year22. A driveway onto a state highway needs a state access permit23. Private wells need a state drilling permit from NJDEP24.

  • Septic authority, well rules, RV and tiny-home rules inside Irvington Township are unconfirmed; ask the township before relying on them13.
  • Owner-builders still need construction permits and inspections, plus a state affidavit before a certificate of occupancy6.
