Do you need a building permit in Parsippany-Troy Hills, NJ?

Yes. New Jersey requires a permit from the local construction official before construction, enlargement, repair, renovation or demolition of a structure begins5. Inside Parsippany-Troy Hills Township, the township's construction division processes applications, reviews plans, issues construction permits and performs inspections10. Plan-review fees may be required when you apply11. We could not confirm the township's own exemption list or fee schedule beyond the state rules, so ask the construction division before you start small projects.

Who issues building permits in Parsippany-Troy Hills, and how do you reach them?

The Division of Construction Code Inspection and Enforcement at the township building on Parsippany Boulevard issues building permits, and it is made up of building, electrical, plumbing, fire and elevator subcodes10. Morris County does not issue building permits; the state code is enforced locally by municipal construction officials12. Applications go to that local office on the state's permit forms13. Reach the division at the phone number and email listed in the office card on this page.

Does Parsippany-Troy Hills have zoning, and what does it mean for RVs, tiny homes and setbacks?

Yes. The township adopts and administers its own zoning chapter2, and Morris County has no zoning power4. The township's Zoning Division requires a zoning permit for new single-family dwellings, additions, detached garages, driveway expansions and similar work14. Lot size, setbacks, height and lot coverage vary by zoning district, and we could not confirm the township's figures for any district15. We also could not confirm any township rule on living in an RV or a tiny home, so ask the Zoning Division before you plan on either. Manufactured HUD homes are limited to single-family use in the state code16.

How do septic permits work in Parsippany-Troy Hills?

Septic is handled by the township's own health office, not the county. The Department of Health and Human Services licenses septic systems and inspects septic repairs173. State law bars a building permit until the board of health certifies the sewerage facilities18, and a septic system may not be covered until the health office has inspected it19. In Morris County only about 12% of mapped soils rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system20. We could not confirm the township's private-well rules; the state requires a drilling permit21.

Building a home in Parsippany-Troy Hills: the steps, in order

  1. Confirm the lot's zoning district and get zoning permit approval from the Zoning Division14.
  2. Check flood-hazard status; development in a regulated flood area needs a permit and goes through the Floodplain Administrator7.
  3. Get the health office's septic plan approval, which must come before the building permit18.
  4. Apply to the construction division for building permits and plan review10.
  5. Keep work stopped at the inspection points the code sets, such as footings and rough plumbing and electrical22.
  6. Obtain a certificate of occupancy before anyone uses the new building23.

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

Morris County's rules cover land outside the township's offices only in narrow ways: subdivision applications are also submitted to the county for review, though minor subdivisions that do not front on county roads are exempt24. A driveway or utility work within a county right-of-way needs a permit from the County Engineering Division25, and access onto a state highway needs a state access permit26. Inside the township, subdivision and site plans are regulated under the township's land-use chapter27. For land outside township limits, see the Morris County page. Morris County's typical home value is about $717,00028 and its effective property tax rate is about 1.8%29.

Watch-outs

  • Parsippany-Troy Hills does not rely on the county for building permits, zoning or septic; calling the county planning counter for any of these will send you to the wrong office23.
  • Owner-builders must file an affidavit with the construction official before a certificate of occupancy, acknowledging the work is not covered by the state new-home warranty30.
  • Short-term rentals in New Jersey are largely subject to municipal ordinance31, and we could not confirm township rules on RV living, tiny homes, short-term rentals, setbacks or minimum home size; ask the Zoning Division before you buy.
