Raritan Township (Hunterdon County), New Jersey Building Permit Guide

In Raritan Township (Hunterdon County), the Construction Office at 1 Municipal Drive, Flemington, enforces the Uniform Construction Code; Rich Sodano is the Construction Official. The office will not accept a construction application that needs zoning approval unless the approved township zoning permit comes with it. Its posted fee schedule charges $30 per $1,000 of estimated cost for alterations and repairs, with a $50 minimum on one- and two-family homes, and a 10% plan review fee paid before review. This is the Hunterdon County township with its offices in Flemington, not Raritan Borough in Somerset County.

What requires a building permit in Raritan Township?

The office describes the UCC as six subcodes (building, plumbing, mechanical, electrical, fire and elevator), and any work they regulate needs a construction permit. Ordinary maintenance under N.J.A.C. 5:23-2.7 needs no permit; minor work under N.J.A.C. 5:23-2.17A needs one but may start once the office has been notified. The township’s own fee schedule shows the jobs it permits most often, and the zoning office lists what needs a zoning permit first.

What the township decides and what the state holds

The code books are the state’s. Raritan sets the construction fees (Section 230-3 of the township code), the Land Development Code in Chapter 296, the zoning permit fees, stormwater rules under Ordinance 23-22, a tree removal and replacement ordinance adopted in spring 2024, and its own Board of Health permits for septic systems and wells. The zoning office answers one common question directly: a garage may only house vehicles and cannot be converted into living space.

Raritan Township building department: who handles permitting

The Construction Office (Code Enforcement) issues permits, with subcode officials reviewing plans and inspecting under the Construction Official, who releases permits and approves certificates of occupancy. DCA’s roster as of September 2, 2026 lists township officials for the building, electrical, fire protection and plumbing subcodes, and DCA itself for elevators. Zoning permits come from a separate Planning & Zoning Department in the same building.

Raritan Township permit types

A construction application is the permit form (official three-part jackets are available at the office) plus an original and two copies of each technical section the work needs. Plans and diagrams go in two copies, signed and sealed by a licensed architect or engineer, with two copies of specification sheets for any equipment and the chimney verification form where it applies. General contractors attach a copy of their state home improvement contractor registration.

Residential permits

• Finished basements. The township’s checklist wants two sets of scaled drawings signed by the owner on every page, showing room uses, partitions, egress, stairs and guards, the mechanical equipment, fire blocking and smoke detectors. Owner-occupants may draw their own; otherwise a New Jersey architect must, and contractors may not prepare the drawings. A basement room is a bedroom only with a door to the outside or an egress window.
• Pools. Approved zoning comes first, then the building, electrical and plumbing sections (fire too for an indoor pool with a gas heater). An in-ground pool needs two copies of sealed structural plans and temporary fencing during construction.
• New houses. The zoning guidelines list three copies each of a plot plan, a driveway permit approved by the township or county engineer, the septic and well permits, and floor plans and elevations, plus an affordable housing development fee in most cases.

Commercial permits

A business moving into an existing space needs a certificate of continued occupancy, which always involves zoning, the fire marshal and construction, even with no construction work. The zoning certificate of reoccupancy costs $100 and needs three copies of a floor plan, a sewer capacity letter from the Raritan Township Municipal Utilities Authority if the site is sewered, and county health approval for food or retail; the fire marshal’s business registration and all four subcode sections marked “CCO Only” complete the file. Any interior alterations need their own zoning and construction permits.

For tenant improvements and new commercial builds, Alliance handles commercial permit filing through issuance. More on this: commercial building permits explained.

What comes before the construction permit

• Zoning permit. Required for virtually all improvements: new dwellings, additions, fences, garages, patios, walkways, HVAC and generator units, decks, finished basements, pools, hot tubs, driveways, sheds, pergolas and gazebos, commercial changes of use and signs. File one application per item with three copies of the survey; the office has 10 business days from a complete submission and warns it is short-staffed.
• Setbacks to know. A shed under 180 square feet and under 10 feet high usually sits 5 feet from the line, otherwise 15 feet; detached garages are capped at 20 feet high, 1,500 square feet and three vehicles; pools and their decking keep at least 15 feet from side and rear lines.
• Stormwater and grading. Adding 1,000 square feet or more of impervious surface, or disturbing more than 2,500 square feet, triggers stormwater measures; the grading plan application costs $150 plus a $600 escrow.
• Health. On septic, a Hunterdon County Health Department referral comes first.
• Boards. The Planning Board, Zoning Board of Adjustment and Technical Review Committee hear site plans, subdivisions and variances; the Hunterdon County Planning Board also reviews subdivisions and site plans.

Raritan Township permit costs and fees

The Construction Office posts its fee schedule as a scanned table (undated) alongside Ordinance 18-10, which repealed and replaced the previous fee section and was introduced on March 6, 2018 with a hearing set for March 20, 2018; the fees are codified in Section 230-3. The schedule waives construction fees for accessibility work for medically disabled persons and gives U.S. veterans a 25% discount on work at their own home.

Worked example from the schedule: a $30,000 kitchen renovation in a house is 30 × $30 = $900 in building fees; the schedule’s 10% plan review fee ($90) is paid before review starts, and the state training fee adds $57. Zoning permit fees (revised October 9, 2023) are separate: $20 for new air conditioners, generators and fuel tanks; $50 for decks, sheds, fences, pools, patios, solar, finished basements, interior alterations and additions; $150 for a new house; $250 for a new non-residential building. After 90 days no construction fees are refunded, and before then the plan review and state fees are kept.

Trade permits and who may pull them

Electrical, plumbing, mechanical and fire work are reviewed and inspected by the township’s subcode officials, each named with an extension on the Construction page; elevator devices go to DCA. Trade minimums on houses are $50 for electrical, plumbing and fire work and $75 for the first mechanical device.

• Electrical. Fixtures, receptacles and switches cost $50 for the first 50 and $10 for each additional 20; a 200-amp service is $100; a house pool’s wiring is $70; commercial-use pools need a $100 annual electrical inspection with a bonding certificate.
• Plumbing and gas. Water closets, sinks, showers, dishwashers, hose bibs and similar fixtures are $13 each; sewage ejectors, gas piping, backflow preventers, interceptors and water conditioning equipment are $75 each.
• Credentials. Electrical contractors, master plumbers and HVACR contractors hold state licenses, and the office asks general contractors for their state home improvement contractor registration. New Jersey has no general contractor license; new-home builders register with DCA, and owners doing work on their own home are exempt from registration.

How to apply for a Raritan Township building permit

Review, corrections and what causes delay

The UCC gives the office 20 business days to act on a complete application (N.J.A.C. 5:23-2.16), and changes after approval are billed as partial reviews at $35 per half hour. Applications that need zoning but arrive without the approved zoning permit are not accepted, which is the most avoidable delay; missing seals on plans and missing county health approvals on septic lots are the next.

Inspections and certificates in Raritan Township

Inspections are booked by phone at 908-806-6114. For pools, the township’s guide lists the building footing, steel, pre-collar, post-collar and final or barrier inspections, the electrical trench, bonding and bonding-grid inspections, and the plumbing bottom-drain rough and final, plus gas piping for heated pools. New houses need a surveyed foundation location plan approved by zoning before the framing inspection. A certificate of occupancy costs 10% of the permit fees, a first temporary certificate is free if the full fee is paid, and a certificate of approval for completed work has no charge.

Smoke and carbon monoxide certificate before a sale or rental

Raritan’s Department of Fire Safety, which also serves Readington, Kingwood and Tewksbury, issues the certificate of smoke detector compliance required before a home is sold, leased or otherwise changes occupancy. Its fee depends on notice: $55 if the application and fee arrive 11 or more business days before closing, $100 at four to 10 business days, and $160 inside four business days, with $55 for each re-inspection. Inspections happen on Wednesdays and the office calls on the Monday before with a time slot. Hardwired detectors may not be swapped for battery units, battery-only alarms must be 10-year sealed units, detectors must be at least 36 inches from ceiling fans, and a certificate lapses if the change of occupancy does not happen within 90 days.

New Jersey building code in Raritan Township

The township enforces the statewide UCC. The 2024 I-codes, the 2024 National Standard Plumbing Code and the 2023 NEC apply from August 17, 2026, and a complete application with all prior approvals may still be filed under the 2021 codes and 2020 NEC until February 17, 2027; older code editions printed on some township handouts predate that change. FEMA lists Raritan Township (community 340240) as participating in the National Flood Insurance Program, and new flood maps take effect there on November 13, 2026, so flood zone checks should use the new maps from that date.
