Ewing Township, New Jersey Building Permit Guide

In Ewing Township the Construction Office of the Code Enforcement Department, at 1666 Pennington Road (609-883-2900), enforces the Uniform Construction Code under Construction Official Jim Megna. Inspections and complaints go through the township’s SDL portal first and email second, emergency repairs can start once the office is told as long as the permit follows within 72 hours, and every home or commercial building offered for resale needs a Division of Housing inspection. Owner-occupants aged 65 or older can ask for 25% off township-issued construction permits.

What requires a building permit in Ewing?

Ewing’s office tells homeowners that permits are required for most construction work, whether or not a contractor is hired, and to call if unsure. The state defines the exemptions: ordinary maintenance under N.J.A.C. 5:23-2.7 needs no permit, and minor work under N.J.A.C. 5:23-2.17A needs one but may begin after notice to the office.

Emergency work, such as a roof leak or a failed heater, can begin as soon as the office has been notified, and the owner then has 72 hours to file the permit requests.

What Ewing decides and what the state holds

The state writes the codes; Ewing runs the enforcing agency, sets its fees in the township code, and adds its own programs: the senior discount, the resale and rental inspections of the Division of Housing under its housing ordinances, yearly rental registration (Ordinance 10-07), and zoning under the township’s land use ordinance, guided by the 2006 Master Plan re-examined in 2013. Ewing residents may also add a second water meter for irrigation, or a meter for sewer usage at homes with wells, installed under the office’s procedure.

Ewing building department: who handles permitting

The Construction Office reviews applications and plans for building, electrical, elevator, fire, HVAC and plumbing work, inspects residential, commercial and industrial buildings, and checks damaged buildings before reoccupancy. Jim Megna is Construction Official, with an assistant construction official, and building, electrical, fire and plumbing subcode officials listed on the township page. DCA’s roster as of September 2, 2026 names Municipal Inspection Corp., a private agency, for the elevator subcode.

Ewing permit types

The office’s filing guide describes a complete application: a properly signed F-100 permit folder, neatly completed technical applications, every required prior approval, two sets of plans, two sets of manufacturer specifications or installation manuals, and copies of the contractors’ licenses.

Residential permits

• Who draws the plans. A homeowner may draw plans for a single-family house they live in, submitted in duplicate with the technical applications. The filing guide adds that an owner who does not live in the house needs a New Jersey licensed design professional.
• Contractor-filed jobs. The contractor submits all permit applications, the homeowner does not have to sign the permit forms, and a contractor may not ask the owner to sign as the person doing the work unless that is true.
• Pools. Above-ground and in-ground pools are built to the International Swimming Pool and Spa Code chapters the office links.
• Finished basements. The guide’s tips include perimeter fire blocking before framing, marking plumbing clean-outs, and planning for combustion air.

What the plans should show

The filing guide asks for two copies of drawings to scale: a foundation plan, floor plans, a truss layout, elevations, and details and cross sections, with separate electrical, HVAC, plumbing and fire protection plans where that work is included. Supporting papers can include manufacturer specifications, ResCheck or ComCheck energy calculations, engineered lumber or truss calculations, and a homeowners association letter approving the work. For homeowners drawing their own plans, the guide suggests graph paper at a quarter inch to the foot, a dimensioned plan of the existing layout, and copies of that plan to mark up for each trade.

Commercial permits

Commercial drawings must be prepared by a New Jersey licensed architect or engineer and filed in duplicate, and the office requires final as-built drawings in digital form on a CD at the end of the job. A commercial tenant change or property transfer is filed as a commercial certificate of occupancy on the zoning permit form, a commercial building offered for resale also needs the Division of Housing inspection, and fire prevention handles business registrations and fire 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. Many applications go to zoning first. The form covers buildings, pools, fences, driveways, PODs, donation bins and commercial certificates of occupancy, and needs a survey (shown to scale) unless the zoning officer waives it.
• Prior approvals. The zoning officer flags reviews by the township engineer, the Mercer County Soil Conservation District, and the Delaware and Raritan Canal Commission, and may assess an affordable housing (COAH) fee.
• State approvals. The filing guide lists wetlands, other DEP and NJDOT approvals among the prior approvals a site may need, and the zoning form has its own box for work in a flood hazard area.
• Boards. The Planning Board (nine members, two alternates) hears major subdivisions, site plans and bulk variances; the Zoning Board of Adjustment (seven members, two alternates) hears use variances.

Ewing permit costs and fees

Ewing’s construction fees are set in the township code, which is hosted on eCode360, rather than on the construction pages; the office prices each technical section when it reviews the application. The state training fee surcharge is added to each permit. The fees Ewing prints on its own forms are these:

The senior discount has conditions: the applicant must own and live at the property and show proof of age and residency such as a driver’s license (no P.O. boxes), and must ask before the permit is issued, because no discount is given once a permit has been issued and paid. It applies only to Ewing’s own permits, not to Mercer County or state fees. Example from the printed fees: selling a two-unit house means a resale inspection at $125 per unit, or $250, before the transfer.

Trade permits and who may pull them

Electrical, plumbing, fire and mechanical work go on their own technical applications within the permit and are reviewed and inspected by Ewing’s subcode officials; elevator work is inspected by Municipal Inspection Corp. Ewing’s homeowner handout tells residents to ask to see a contractor’s state number before hiring, and lists the prefixes to look for:

• 13VH for a registered home improvement contractor
• 34EB for a licensed electrical contractor
• 36BI for a licensed master plumber
• 19HC for a licensed HVAC contractor

Those numbers must appear on the contractor’s vehicles and letterhead. New Jersey has no general contractor license; builders of new homes register with DCA. A single- or two-family homeowner may do the work on a home they own, but must be able to perform it. Under N.J.A.C. 13:45A-16.2(a)10ii, final payment to a home improvement contractor is not due until all final inspections are approved, and complaints about contractor performance go to the Division of Consumer Affairs.

How to apply for an Ewing building permit

Review, corrections and what causes delay

Ewing’s guide says reviews should be complete within 20 business days of a complete submission, matching N.J.A.C. 5:23-2.16, and that a job may move faster or slower depending on how many other offices must approve it. The office singles out missing prior approvals as a frequent problem, and an application goes to the subcode officials only after staff have confirmed it is complete.

Inspections and certificates in Ewing

Request inspections through the SDL portal; if you email instead, give the permit number, the inspection type, three possible dates (no time frames) and the address. Work that will be covered must pass a rough inspection first. Ewing calls the structural rough a frame inspection, and it will not do the frame inspection until every other rough inspection has passed. When the finals pass, request the certificate of occupancy or approval, and make sure the prior-approval agencies have signed off: zoning or planning, engineering, Ewing Fire Safety, the Ewing-Lawrence Sewerage Authority, the Mercer County Soil Conservation District and any state agency.

Resale and rental inspections

Every dwelling or commercial building offered for resale must be inspected and approved by the Division of Housing; apply on the property transfer resale application, giving the owner’s name even when the seller is an LLC, and expect a Tax Assessor representative to attend the inspection. The office checks for open UCC permits and violations. Rental homes are registered every year by January 1, with rental fire forms due January 31, and each new tenant triggers a property maintenance inspection. The Housing page adds that for any residential transfer, battery smoke alarms must be the 10-year sealed type, and a portable extinguisher (rated at least 2A-10B:C, between 3 and 10 pounds, serviced and tagged within 12 months or newly bought with a receipt) must hang within 10 feet of the kitchen, in the exit path, no more than 5 feet up.

New Jersey building code in Ewing

Ewing enforces the statewide UCC through its own subcode officials. The 2024 I-codes, the 2024 National Standard Plumbing Code and the 2023 NEC apply from August 17, 2026; a complete application with every prior approval may be filed under the 2021 codes and the 2020 NEC until February 17, 2027. FEMA lists Ewing Township (community 345294) as participating in the National Flood Insurance Program, with flood maps effective July 20, 2016, and the zoning permit form flags lots in a flood hazard area.
