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

Yes. Roxbury Township has established its own State Uniform Construction Code enforcing agency, so building permits for construction inside the township come from the township, not from Morris County1. New Jersey's statewide code requires permits for construction, enlargement, alteration, repair and changes of use10. The township construction department states that its permit process begins with plan review11. Work is inspected, and a certificate of occupancy is required for new buildings statewide12.

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

The Roxbury Township Construction Department processes permits, inspections and certificates of occupancy under the state code11. Call (973) 448-2009 or visit 1715 Route 46, Ledgewood, NJ 0785211. Morris County does not issue building permits in Roxbury; the township office does13. A zoning approval is a separate step handled by the Planning and Zoning Department14.

Does Roxbury Township have zoning, and what does it mean for setbacks and lot coverage?

Roxbury Township has its own zoning ordinance, dating to 1965 and amended since4. The code divides the township into 40 districts2, so setbacks and coverage depend on your parcel's district. In the R-2 Residence District, the minimum front yard setback is 50 feet, reduced to no closer than 40 feet where neighbors form an established setback15. In the R-R Rural Residence District, impervious coverage is capped at 20% of lot area and building coverage at 15%16. The township's zoning office states that a permit is required for fences, decks, patios, pools, hot tubs, spas, building additions and sheds14. Minimum dwelling size, RV occupancy and tiny-home rules were not confirmed; ask the zoning officer at (973) 448-200814.

How do septic permits work inside Roxbury Township?

Inside Roxbury Township, the township Health Department reviews septic plans for new construction and alterations before installation17. The department also conducts periodic inspections during installation17. A permit is required for repairs or alterations to an existing septic system18. Statewide, a septic permit is required for any realty improvement needing sewerage facilities, and systems must be inspected before they are covered1920. Where public sewer exists, new buildings must connect before a certificate of occupancy is issued6.

Do you have to connect to public sewer or water in Roxbury Township?

Often, yes. New construction on property within 250 feet of the township water system must apply for a connection permit7. A structure needing additional water allocation must connect if water mains are within 200 feet and capacity is available7. After the township gives notice that sewer service is available, owners have 180 days to connect7. For a new well, the Health Department requires a satisfactory water test21.

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

  1. Confirm your zoning district and its setbacks and coverage limits with the Planning and Zoning Department at (973) 448-200814.
  2. Ask the Health Department at 973-448-2000 whether public sewer and water reach your lot, or get septic plans reviewed17.
  3. Apply for a zoning permit; the residential application fee is $3014.
  4. Submit the construction permit application to the Construction Department for plan review11.
  5. Pass inspections and obtain a certificate of occupancy12.

What to check before you buy land in Roxbury Township

Floodplain: the zoning code contains development controls in flood-hazard areas, so check the lot against the flood-hazard map22. Soils: only about 12.4% of Morris County soils are rated not limited for a conventional septic drain field, so expect a site evaluation and possibly an engineered system23. Taxes: Morris County's effective property tax rate is about 1.8%24. For land outside Roxbury, see the Morris County page.

Watch-outs

  • Rules for RV living, tiny homes, accessory dwellings and minimum home size in Roxbury Township were not confirmed; ask the zoning officer at the Planning and Zoning Department before relying on any of them14.
  • Septic rules inside Roxbury come from the township Health Department, not from the Morris County Division of Public Health, so call the township office17.
  • Short-term rentals are addressed in the township code; confirm with the township before buying a property for rental use25.
