Morris County, New Jersey has no county building department and no county zoning: it has no unincorporated land, so every municipality issues its own construction permits and sets its own zoning under New Jersey's statewide Uniform Construction Code12. A permit is required before most construction, alteration or demolition work anywhere in the county3. Septic permits also split by municipality rather than running through one county office4.

Do you need a building permit in Morris County, New Jersey?
Yes. New Jersey's statewide Uniform Construction Code requires a permit before you construct, enlarge, repair, renovate, alter, reconstruct or demolish a structure, or change a building's use, anywhere in Morris County3. Morris County itself has no county-level building department: each of its municipalities appoints its own construction official who issues the permit and enforces the code1. In the Town of Morristown, for example, the construction code office "administers and enforces the New Jersey State Uniform Construction Code (UCC) by: processing permit applications for new and existing building construction reviewing applications for compliance with the UCC conducting inspections and issuing certificates of occupancy or approval"14. Ordinary maintenance, defined narrowly under state code, is the main exception that does not need a permit3.
Who issues building permits in Morris County, and how do you reach them?
Morris County has no single "county building department": every municipality within the county appoints its own construction official to issue permits and enforce the code1. The Town of Morristown's Division of Building and Uniform Construction Code is one working example: it sits at 200 South Street, 2nd Floor, Morristown, NJ 07960, and can be reached at 973-292-671214. Before you apply, line up zoning approval for your specific municipality, because "construction work often requires approvals from other agencies before a construction code permit may be issued," including zoning or health approvals14. For a single-family home, New Jersey lets the resident homeowner prepare their own construction plans instead of hiring a licensed architect7.
Does Morris County have zoning?
Morris County does not zone land itself: New Jersey's Municipal Land Use Law assigns zoning power to municipalities, not counties, so no unincorporated land exists in the state and every parcel in Morris County falls under a municipal zoning ordinance2. Minimum lot size, minimum dwelling size, setbacks, lot coverage and building height are all set district by district in each municipality's own ordinance, not by one countywide rule8915. In Morristown, the Land Use Division "reviews zoning permit applications" and "issues zoning permits, continuing use certificates, verification of zoning letters and related approvals" from its office at 200 South Street, 2nd Floor, Room 233, Morristown, NJ 07960, reachable at (973) 292-672216. Because zoning is set town by town, Morristown's rules will not automatically apply in another Morris County municipality, so confirm the ordinance for your specific municipality before you buy or build5.
How do septic permits work in Morris County?
Individual septic systems under 2,000 gallons per day are permitted by the "local health authority" under New Jersey's statewide standard, N.J.A.C. 7:9A, and in Morris County that authority is split between the county and its municipalities4. The Morris County Division of Public Health is the local health authority for only Boonton Township, Denville, Hanover, Harding, Mendham Township and Morris Plains; every other Morris County municipality runs its own local health department that issues septic approvals instead6. Reach the Morris County Division of Public Health at 973-631-5484 or PO Box 900, Morristown, NJ 07963, if your land sits in one of those six towns; otherwise your own municipal health department is the one to call6. USDA soil survey data rates only 12.4% of Morris County's soils as free of severe limitations for a conventional septic drain field, so a site evaluation, and on tougher lots an engineered or alternative system, is common here13.
Can you live in an RV or tiny home on your land in Morris County?
There is no county or statewide rule that settles RV or tiny-home living on a residential lot in Morris County: zoning is entirely municipal, so whether a camper, RV or tiny home counts as a permitted dwelling or accessory use depends on your specific municipality's zoning ordinance2. Manufactured HUD homes are a separate, narrower category: state rules limit them to use group R-5, meaning they may be placed only as single-family dwellings, and installation must meet federal standards through a HUD-licensed installer10. Minimum dwelling size, where a municipality sets one, is also district-specific rather than one Morris County number9. Before you park or build an RV, tiny home or manufactured home on land in Morris County, call the zoning office for that specific municipality, such as Morristown's Land Use Division, and ask about accessory dwellings and temporary occupancy16.
Building a home in Morris County: the steps, in order
- Confirm your municipality's zoning ordinance allows the home you want to build, and get zoning approval before you apply for a construction permit; Morristown's Land Use Division handles this locally16.
- If you need a septic system, contact the local health authority for your specific municipality: the Morris County Division of Public Health for Boonton Township, Denville, Hanover, Harding, Mendham Township or Morris Plains, or your town's own health department elsewhere, before you finalize a site plan6.
- File a construction permit application with your municipality's construction official, covering each subcode that applies to the job, such as building, electrical and plumbing3.
- Pay the plan-review fee: state rule sets it at not less than five percent nor more than 25 percent of the construction-permit fee17.
- Schedule inspections at each required stage: footing trenches before footings are poured, rough plumbing and electrical before framing is closed in, and framing before it is covered by finishes18.
- If your driveway will connect to a state highway, apply separately for a NJDOT access permit before starting work19; if it connects to a county road instead, Morris County Engineering & Transportation issues the road opening permit20.
- Get your certificate of occupancy from the construction official once every required inspection is complete18.
What to check before you buy land in Morris County
Morris County is gently sloped overall: 84.7% of land sits at 15% slope or less, which favors building, though tree cover still means most lots need clearing21. Soils rate poorly for conventional septic across much of the county: only 12.4% avoid severe limitations, so budget for a site evaluation and possibly an engineered system before you commit to a lot without existing sewer service13. Annual precipitation runs about 50 inches, and the county sits in severe drought only about 2.4% of years, so a private well is generally a reliable water source here2223. Typical home values run around $717,390 and the effective property tax rate is about 1.8%, for a median tax bill near $10,001 a year, so factor taxes into your budget241112. If your parcel touches a state highway, plan for a separate NJDOT access permit before you can build a driveway19. Morris County sits about 22 miles from the nearest metro area, close enough for regular commuting and supply runs25.
Watch-outs
- Zoning, building permits and RV or tiny-home rules in Morris County are set town by town; Morristown's rules do not apply anywhere else in the county2.
- The Morris County Division of Public Health is the local septic authority for only six of the county's municipalities (Boonton Township, Denville, Hanover, Harding, Mendham Township, Morris Plains); everywhere else, a municipal health department issues the septic approval6.
- A driveway or other access point onto a state highway needs a separate NJDOT permit, on top of any municipal approval19.
