New Jersey's Biggest Permit Jobs: Where They Cluster

TL;DR

• 41,560 New Jersey permits name all four subcodes, median project cost $124,000.
• Cape May converts 13.5% of tagged permits into these jobs, Salem only 2.9%.
• Volume leaders and concentration leaders are different counties entirely.
• Alteration, not new construction, is the largest work class in the cohort.

New Jersey's highest-value construction permits are not where the permit volume is. Of the 41,560 permits in our file that name all four subcodes, and which carry a median project cost of $124,000, the heaviest concentration sits in Cape May at 13.5% of tagged permits, followed by Atlantic at 11.0%. Bergen and Monmouth, the two counties most people would name first, run at 8.3%.

That gap is the point of this article. Choosing a New Jersey territory by total permit count and choosing it by high-value job density give you different answers, and the second answer is worth more per hour of prospecting.

What is a four-subcode permit in New Jersey?

It is a permit whose public description names building, electrical, plumbing and fire together, which happens when a job is big enough to touch all four at once.

New Jersey does this differently from most states, and the difference is what makes the data useful. Under the Uniform Construction Code at N.J.A.C. 5:23, a construction permit is one application plus a technical section for each discipline involved. Each section is reviewed by its own subcode official, licensed by the Department of Community Affairs, working under a municipal construction official. Permits are issued by the municipality, not the county, so treat county names here as coverage labels rather than permitting authorities.

The consequence for anyone reading the record is that the permit title carries a parenthetical listing exactly which technical sections were filed. Something like alteration, followed by building, electrical, plumbing and fire in brackets. That parenthetical is present on 548,136 of our 640,741 New Jersey records.

Count the discipline words and you have a job-size proxy that sits in plain sight. A permit naming one subcode runs a median project cost near $4,000. Four subcodes runs $124,000. The mechanics of that spread are covered in our map of New Jersey permit leads across all 21 counties. This piece is about the 41,560 permits at the top of it, and specifically about where they are.

Where do the big jobs actually cluster?

In the shore counties, at a rate that has almost nothing to do with their size.

The table below ranks all 21 counties by four-subcode concentration. The percentage is the share of that county's tagged permits, meaning those carrying a subcode parenthetical, not the share of all its permits.

County	Four-subcode permits	Share of tagged	Median project cost
Cape May	1,941	13.5%	$161,767
Atlantic	1,472	11.0%	$114,610
Ocean	5,004	9.5%	$110,000
Essex	2,718	8.9%	$144,850
Union	2,035	8.6%	$115,000
Bergen	4,681	8.3%	$142,400
Monmouth	4,603	8.3%	$149,000
Hudson	738	7.8%	$92,138
Gloucester	1,692	7.5%	$134,000
Middlesex	3,865	7.4%	$101,115
Morris	2,965	7.4%	$155,500
Mercer	2,173	6.7%	$152,000
Camden	1,899	6.5%	$107,950
Somerset	1,869	6.5%	$81,700
Passaic	777	5.7%	$96,500
Cumberland	281	5.4%	$106,400
Burlington	1,478	4.9%	$99,000
Warren	354	4.5%	$129,855
Hunterdon	450	3.8%	$71,350
Sussex	464	3.2%	$115,000
Salem	101	2.9%	$126,070

Read the first column and the third column against each other and the picture changes twice.

By count, Ocean leads the state with 5,004, ahead of Bergen and Monmouth. By concentration, Cape May leads at more than four times Salem's rate. Cape May holds 14,415 tagged permits, roughly half Camden's 29,042, yet produces 1,941 four-subcode jobs against Camden's 1,899. Same output, half the file to work through.

Why do the shore counties punch above their size?

Because coastal building stock generates whole-building work rather than incremental work, and whole-building work pulls every subcode.

Cape May, Atlantic and Ocean together account for 8,417 of the 41,560, which is 20.3% of the state's four-subcode permits from counties holding a much smaller share of its total volume. Cape May also carries the highest median project cost of any county in the state at $161,767.

There is a caveat that belongs right next to that finding rather than buried later. The shore counties are the weakest in New Jersey for address completeness. Across the four-subcode cohort the address field is populated on 80.6% of records, and in Cape May it drops to 77.7%. The jobs are real and the project costs are real. Roughly one in five of them cannot be tied to a street address from our file.

Morris and Mercer are the quieter story in that table. Neither leads on concentration, at 7.4% and 6.7%, but both carry medians above $150,000, which puts them ahead of Ocean's $110,000 on value per job. Somerset is the inverse, with a respectable 6.5% share and an $81,700 median, the lowest of any large county.

What kind of work are these permits?

Renovation, mostly, which is not what the phrase "biggest jobs" usually suggests.

Within the 41,560, alteration is the largest work class at 19,922 permits. New construction accounts for 14,057 and additions for 7,558. A gut renovation pulls all four subcodes for a straightforward reason: once walls are open, the wiring, the plumbing and the fire protection all get touched, so all four technical sections get filed.

The cost distribution inside the cohort runs long. The median is $124,000, the 90th percentile is $556,000, and 1,669 of these permits record a project cost at or above $1 million. That tail is small in count and large in value, and it is reachable with a single filter.

For most trades the practical read is that the four-subcode filter finds heavy work in existing buildings. If you sell into renovation rather than ground-up construction, this is your cohort, and the alteration share says so.

What can this data not tell you?

It cannot tell you who to call, and pretending otherwise would waste your money.

New Jersey carries zero contractor names and zero owner names. Not sparse, not partial. Both fields are empty across all 640,741 records. There is also no latitude or longitude anywhere in the New Jersey file, so radius and drive-time targeting are unavailable, and the feed runs roughly 9 to 12 days behind rather than next-day.

What it does carry is unusually good on the project side. Project cost is present on 640,736 of 640,741 records, the subcode set on 548,136, and a work description on every one. That combination is why the analysis above is possible at all, and it is a genuinely better cost signal than most state permit files offer.

So the honest framing is that New Jersey is a targeting dataset rather than a calling list. It tells you which municipalities and which property types are producing six-figure work, and it does that better than the alternatives. The introduction still has to come from you. That distinction is the same one that separates permit records from bought lead lists generally, and it matters more here than in our other states.

How should you use this to pick a territory?

Rank on concentration first, sanity-check on median cost, then discount for address coverage.

Start with the share column, because it tells you how much of your reading time converts into a real target. A rep working Cape May reviews 14,415 tagged permits to find 1,941 large jobs. A rep working Burlington reviews 30,281 to find 1,478. That is more than four times the reading for three quarters of the output.

Then check the median. Concentration alone would send you to Ocean, whose $110,000 median is below the statewide $124,000. Pairing the two columns points at Cape May, Monmouth, Bergen, Essex and Morris as the counties where density and job size both hold up.

Then subtract for the fields you will not get. In the shore counties, plan on roughly a fifth of the cohort lacking an address. That is a real cost and it should change how many counties you take on rather than being discovered in month two. Whether the remainder still pays is a question worth running properly, and the method for that is in measuring return on permit-triggered outreach.

How permits.llc fits in

We hold 640,741 New Jersey permit records covering all 21 counties and 496 municipalities, the largest single-state file we carry. Every figure in this article came out of it, including the county table, the work-class split and the cost percentiles.

A permit is a signal about the property owner, not the contractor, and in New Jersey that signal arrives without a name attached. What arrives instead is the project: what class of work, which subcodes, what it costs, and where. For picking territory and sizing opportunity, that turns out to be the more durable half.

Start with the free dataset and run the subcode count yourself against your own counties at the free NJ permit download. When you want to compare concentration across the 21 counties before committing a rep to one, browse New Jersey coverage by county and pick on density rather than raw volume.
