Do you need a building permit in Dover, New Jersey?

Yes. Construction, enlargement, alteration and changes of use in the Town of Dover are regulated by New Jersey's Uniform Construction Code1, and a permit must be obtained before covered work begins14. Dover's construction office, not Morris County, issues building permits2.

Ordinary maintenance as the state code defines it does not need a permit or notice14. Inspections happen at stages during construction15, and a new building needs a certificate of occupancy after final inspection before anyone uses it16.

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

The Town of Dover Construction Department handles construction permits, inspections and certificates of occupancy2. It sits at 100 Princeton Ave., Dover, NJ 07801, and takes calls on the town's main line, 973-366-22002. The department is headed by a Construction Official who also serves as building subcode official2.

No permit is issued until every required state, county and local approval is in place17. For an owner-occupied one- or two-family addition or alteration, zoning approval must be in place before plan review proceeds17. Fees are set by the municipality within state limits, so ask the office for the current Dover fee schedule18.

Does Dover, NJ have zoning, and what are the lot and house rules?

Yes. The Town of Dover divides itself into zoning districts shown on a town zoning map36. Morris County has no zoning authority over municipalities4.

In the R-1 district, every lot needs a minimum width of 75 feet at the street line and a minimum area of 7,500 square feet9, and a new house needs at least 1,000 square feet of first floor area7. In the R-2 district the minimums are 50 feet of width, 5,000 square feet of lot area10 and 800 square feet of first floor area8.

On residential lots, lot coverage may not exceed 65% or 4,300 square feet, whichever is smaller, and building coverage may not exceed 25%19. Buildings in R-1 and R-2 are limited to 30 feet in height and 2 1/2 stories11. Rules for other districts, and for setbacks, we could not confirm; the zoning office can supply the zoning table for your parcel13.

How do septic permits and wells work inside Dover?

New Jersey requires the local board of health to certify a proposed water supply and sewerage system before a building permit can issue20, and a septic system must be inspected before it is covered21. Municipal or county boards of health can exercise that authority22.

The Morris County Division of Public Health serves six other municipalities, and Dover is not one of them23. Dover operates its own health department5, but we could not confirm whether it, or another agency, approves septic plans inside Dover. Call the Dover Health Department before you plan a septic system or a private well. A well also needs a state drilling permit, with municipal or county health officials issuing the construction permit24.

Can you live in an RV or tiny home on your land in Dover, NJ?

We could not confirm any Dover rule on RV occupancy, temporary camping or tiny-home occupancy, and we found no accessory-dwelling rule either. Because Dover zones by district3, do not assume an RV or tiny home is allowed on a lot. Ask the Planning & Zoning office in writing before you move one onto a parcel13.

A manufactured HUD home is limited statewide to single-family use group R-5 and must meet federal construction standards25. Any permanent dwelling, tiny or not, still goes through the construction permit and certificate of occupancy process16.

Building a home in Dover: the steps, in order

  1. Confirm your lot's zoning district and its lot, house-size, coverage and height limits with the Planning & Zoning office13.
  2. Ask the Dover Health Department what it requires for septic or sewer connection and any well5.
  3. Get zoning approval, then submit your construction permit application to the Construction Department; no permit issues until all required approvals are in place17.
  4. Build with inspections at the required stages15.
  5. Obtain a certificate of occupancy after final inspection16.

If you build your own new home for personal use, you are excepted from new-home builder registration but not from the code or permits12. The certificate of occupancy also depends on an owner-built affidavit filed with the construction official26.

What stays with Morris County, and what to check before you buy in Dover?

Morris County does not issue building permits or zoning inside Dover4. A driveway or utility work within a Morris County right-of-way needs a permit from the County Engineering Division after Planning Board approval27, and access onto a State highway needs a state access permit28. For land outside town limits, see the Morris County page.

Check septic or sewer, well, flood and lot-coverage limits before closing. Morris County's effective property tax rate is 1.8%29, and county median property tax bills are about $10,001 a year30.

Watch-outs

  • We could not confirm who approves septic systems inside Dover; call the Dover Health Department before buying a lot that is not on sewer5.
  • Dover's lot-size, house-size and height numbers are for the R-1 and R-2 districts only; other districts differ, so confirm your parcel's district with the zoning office9.
  • Owner-builders are excepted from builder registration only, not from permits, inspections or the building code12.
  • We could not confirm Dover's current construction permit fees; ask the Construction Department for the fee schedule2.
