Does Mount Olive Township have zoning, and what does it mean for your lot?

Yes. Mount Olive Township adopts its own zoning, with rural, residential, nonresidential and special districts, each with its own use and bulk rules2. Some bulk standards sit in an attached Schedule of Limitations2.

Minimum lot size, setbacks, coverage and height all depend on the district your parcel is in, so find the district before you price a plan8. We could not confirm the full residential schedules; ask the township zoning officer for your parcel's district and limits.

Accessory apartments in the RR-AA and RR-A districts must have at least 400 square feet of gross floor area each9. We could not confirm township rules for tiny homes, RV living or temporary camping on private land, so ask the zoning officer before relying on any of them.

Do you need a building permit in Mount Olive Township, and who issues it?

Yes. New Jersey's Uniform Construction Code requires a permit for construction, enlargement, alteration and similar work statewide3, and Morris County itself does not issue building permits10.

In Mount Olive Township the sequence matters: a building permit requires an approved zoning permit accompanying the plans1. The township charges a zoning permit and certificate of occupancy fee of $25 per request for residential use6. Construction permit fees themselves vary by municipality11.

A certificate of occupancy is required before a new or altered building is used6. A homeowner building their own owner-occupied home can generally pull permits themselves7.

How do septic permits and wells work in Mount Olive Township?

Mount Olive Township's code has its own chapter on individual sewage disposal and water systems. It contains a permit-required section for septic systems, a certificate of compliance and a license to operate4. Wells have their own permit-required section and certificate of compliance5.

New Jersey also requires a permit for sewerage facilities serving a new realty improvement12, and septic work must be inspected before it is covered13. Drilled wells need a state permit14.

The Morris County Division of Public Health handles septic only in six other municipalities, not Mount Olive15. Ask Township Hall which local health office reviews your septic application.

Building a home in Mount Olive Township: the steps, in order

  1. Confirm your parcel's zoning district and its use and bulk limits with the township zoning officer2.
  2. If you are dividing land, subdivision approval runs through the Planning Board16.
  3. Get the septic and well approvals under the township's Chapter 44545.
  4. Obtain the zoning permit, which must accompany plans for the building permit1.
  5. Obtain the building permit and schedule the code inspections17.
  6. Request the certificate of occupancy before moving in6.

A driveway onto a state highway needs a state access permit18; the township code also has driveway standards for single-family homes19.

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

Morris County does not zone and does not issue building permits for Mount Olive Township20. For land outside the township, see the Morris County page.

Before buying, check the parcel's zoning district, whether public sewer or water is available, and floodplain status. We could not confirm the township's sewer connection rule or floodplain development requirements; ask Township Hall. Morris County's effective property tax rate is 1.8%21, and the typical home value is $717,39022. County soil data rates only about 12% of soils as not limited for a conventional septic drain field, so expect a site evaluation and possibly an engineered system23.

Watch-outs

  • We could not confirm which township office reviews septic permits; call Township Hall at (973) 691-0900 before ordering a soil test24.
  • Residential setbacks, minimum lot sizes and building height depend on the zoning district and were not fully confirmed; get them in writing from the zoning officer25.
  • A zoning permit must come before the building permit, so a plan submitted to the construction office first will be sent back1.
