If you've pulled a permit in New Jersey, you've seen the form numbers — F100, F120, F140 — and probably wondered which one goes with what. The state UCC forms are some of the least-intuitively-named documents in NJ construction, and filing the wrong one is a real source of delay.
Here's the plain-English breakdown.
F100 — the Construction Permit (the jacket)
The F100 is the top-level Construction Permit Application, often called the "construction jacket." It's the summary document that ties all the trade applications together.
Think of F100 as the cover sheet. It doesn't contain trade-specific technical details — those go on the sub-applications. F100 tells the municipality:
- Property address, block and lot
- Owner of record
- Whether the project is new construction, addition, or alteration
- Estimated cost of work
- Use group (R-3, R-5, B, M, etc.)
- Whether ALL required trade subcode applications are attached
Every permit application in NJ gets an F100, regardless of whether the work is electrical only, plumbing only, full renovation, or new construction. If only one trade is involved, you still need the F100 as the jacket.
F120 — the Electrical Subcode
The F120 is the Electrical Subcode Technical Section. This is where the electrical-specific details live:
- Number and amperage of circuits being added or replaced
- Service size (existing and proposed)
- Motors, generators, transformers being installed
- Lighting fixture count (commercial)
- Signs, heat pumps, EV chargers, solar arrays
- Pools, hot tubs, fountains
- Any other trade-specific loads
F120 includes a fee schedule on the back — the electrical permit fee is calculated based on the number and type of devices. This is the form that determines how much the electrical permit actually costs.
If you're pulling any electrical permit, you need F100 + F120 at minimum.
F140 — the Fire Protection Subcode
The F140 is the Fire Protection Subcode Technical Section. It covers:
- Fire alarm systems (new, modified, replaced)
- Sprinkler systems
- Standpipes
- Smoke control systems
- Commercial kitchen hood suppression
- Any fire-life-safety system subject to NJ UCC
Most residential electrical work does not require an F140 — a simple panel upgrade or kitchen rewire doesn't touch fire protection. F140 becomes relevant when:
- You're installing or modifying a fire alarm system (new smoke detectors on their own dedicated circuit, interconnected AFCI-protected systems, etc. — check with the fire subcode official, not every job triggers it)
- You're doing any sprinkler work
- You're doing commercial work that includes detection or suppression
If you're unsure whether a job requires F140, call the municipality. The fire subcode official will tell you — and you'd rather ask before filing than have the permit bounced because F140 was missing.
Other subcode forms you should know
Beyond the big three, NJ uses additional subcode technical sections:
- F160 — Plumbing Subcode (water supply, drain-waste-vent, fixtures, water heaters, backflow, gas piping)
- F170 — Building Subcode (structural, egress, fire-resistance ratings, occupancy)
- F180 — Elevator and lifts
- F190 — Mechanical / HVAC (if not covered under the Building Subcode — this varies by municipality)
For a full kitchen renovation that includes electrical and plumbing: you'd file F100 + F120 + F160.
For a full house remodel with structural changes: F100 + F120 + F140 (if alarm/sprinkler touched) + F160 + F170.
How they all fit together
Every NJ permit packet has:
1. One F100 (the jacket — always) 2. One technical section per trade involved — F120 for electrical, F140 for fire, F160 for plumbing, F170 for building, etc. 3. Supporting documents — load calcs, one-line diagrams, plans, spec sheets 4. Contractor license copies for each licensed trade 5. Property documents — proof of ownership or signed owner authorization
If you're missing any required subcode section, the municipality will return the entire packet. They don't partial-approve.
The most common filing mistake
The single most common mistake we see from contractors new to NJ: filing F120 without F100.
Electrical contractors will fill out the technical section, skip the jacket, and submit. The municipality has to bounce it because there's no jacket to attach the permit to. That's a week lost.
Rule of thumb: if you're filing any subcode technical section, the F100 jacket is required. Always.
Where to find the forms
The official NJ state UCC forms are at nj.gov/dca/codes. Every municipality uses the same state forms — there's no local variant. A Jersey City F120 is identical to a Newark F120.
Some municipalities require additional local forms on top of the state UCC forms (historic district applications, zoning reviews, tree ordinance forms in certain townships). Those are municipality-specific. The state UCC packet (F100 + subcode sections) is not.
The ClearPath approach
We file F100 + appropriate subcode sections on every job, auto-generated from the contract scope. Electrical-only job? F100 + F120. Kitchen renovation? F100 + F120 + F160. Full house rewire with fire alarm? F100 + F120 + F140.
If you tell us the scope and the property address, we'll tell you exactly which forms you need and file them in one packet. Flat fee, all 21 NJ counties, filed the same day for standard jobs.
