How subcontractors find work in building permits: three NC examples with real numbers

Every new house, tenant upfit and addition in North Carolina starts with a building permit, and the permit is public: it names the address, the kind of work, the declared cost and, in most offices, the contractor and a phone number. For a subcontractor or supplier looking for work, that's a list of who is building, and where, that nobody has to hand you. Here are three ways to work it, each run on real permits filed this summer in the offices TarSignal reads. They're worked examples on the public record, not customer stories: the numbers are what anyone could pull from the permits this week.

Example 1: a trade sub looking for builders who'll take a call

Say you're an electrician, plumber, HVAC or framing sub in the Charlotte area looking for new builders. In September 2026, 608 new-home permits were filed in Mecklenburg County, by 143 different builders. Six filed 20 or more homes each, 154 between them; large production builders tend to work with trade partners they already have. The long tail is different. Eighty-two builders filed a single home and 25 filed two to four: custom and small spec builders, most of them reachable at the number on their permit.

In Permit Search, pick the New Build permit type and your county, and look back a few months. The Contractors tab ranks the builders by permits filed. Open one to see their whole permit history, what they build and where, and call with a specific job in mind: the address of their latest permit says more than a general pitch. Then set a Project Alert for new-home permits in your area, so the next builder shows up in your inbox the morning after their permit is published.

Example 2: a commercial sub building a general contractor bid list

Tenant upfits, the build-out of an office, store or restaurant space inside an existing building, are steady work for mechanical, electrical, plumbing, drywall, low-voltage and fire protection subs, and they're run by general contractors who keep bidder lists. In Mecklenburg County, 160 upfit permits were filed from July to September 2026, by 106 different general contractors, and 136 of the permits list a phone number. Most of those contractors filed one upfit in the quarter: 81 of the 106. The busiest filed nine. The median declared cost was about $332,000.

A list of 106 contractors is a bid list most commercial subs don't have. Start from the commercial upfit guide or Permit Search, list the general contractors that filed upfits in your area over the last quarter, and call each one's estimator to ask for their bidders list, naming the upfit you saw on their permit. A contractor that filed one upfit this quarter is still worth the call: the permit shows they're winning work near you now.

Example 3: a supplier sending reps where the homes are going up

A lumber yard, window distributor or appliance dealer doesn't need one builder; it needs to know where the next few hundred houses are. New-home permits by ZIP code show it. From July to September 2026 the busiest ZIP in the offices TarSignal reads was 27591, around Wendell east of Raleigh, with 322 new-home permits from 36 builders. Next came 27703 in east Durham (284), 27545 Knightdale (194) and, in the Charlotte area, 28269 in north Charlotte (190).

Each ZIP code's page shows its permits by month, what's being built and the most active contractors there, which is a rep's route plan: the builders to visit and the streets they're building on. In Raleigh, Wilmington and Asheville, Material Leads goes a step further and lists the build sites whose next material order hasn't been permitted yet, with the builder behind each.

Where these examples stop working

• Some offices publish no contractor: Gaston County, Onslow County, Guilford County, Apex, Fuquay-Varina and Wake Forest. There you get the address and the work, not who is doing it.
• Not every permit has a phone number. Where the office doesn't publish one, TarSignal looks it up only when it matches exactly one contractor, so some stay blank.
• The declared cost is the applicant's figure for the building work alone, and some offices compute it from square footage. Treat it as a size signal, not a budget.
• Offices publish on their own schedule, some days after filing, so the newest week always looks low. Judge an area by the last few months, not the last few days.

How these numbers were counted

Permits filed (or issued, where an office records only that date) in September 2026 for the first example and from July 1 to September 30, 2026 for the other two, from TarSignal's records as of October 24, 2026. Builders and contractors are counted as businesses: different spellings of one name are merged as TarSignal's methodology page describes, and permits whose contractor is blank or a placeholder like "Owner" aren't counted as anyone's. New homes are TarSignal's New build category. Tenant upfits are commercial building permits whose type or description says upfit, tenant improvement or finish, fit-up, interior completion, or a change of tenant, occupancy or use, leaving out residential work and the separate trade permits for the same job. The ZIP ranking leaves out Apex, Fuquay-Varina and Wake Forest, whose portals show only part of their permits; ZIP 27703 includes permits from both Durham's and Raleigh's offices, and 27591 from Wake County's and Johnston County's.
