Step 1: Search Johnston County Inspections' permits-by-date page (free)
The permit office's own records, straight from the source. Search for: mechanical, and new residential dwellings.
- Open the page and pick a date: it lists every permit the county issued that day.
- Each permit shows its address, subdivision, type of construction, square feet, cost and contractor.
- It's one day at a time, so step through the dates to cover a week or a month.
Who's on a permit: Most permits name the contractor, without a phone number.
Step 2: Keep the permits worth a call
Does the work need a permit in North Carolina? Yes. Adding or replacing heating or air-conditioning equipment always needs a permit. So these are the HVAC (mechanical) permits on file, and what each is worth.
New construction
A new-home or commercial building permit means a system to design and install. The builder or general contractor named on it chooses the mechanical sub.
Change-outs
Every replacement in North Carolina needs a mechanical permit, so the record is close to complete. A change-out is a job someone else already won, but the pattern shows which neighborhoods' systems are failing and who's winning them.
Commercial upfits
A tenant upfit almost always moves ductwork or adds equipment. The general contractor on the building permit is the call.

Step 5: Reach out at the right time
On new construction, reach the builder in the weeks after the building permit is issued, before rough-in. For replacements, the permit follows the sale, so use it to find streets, not jobs.

The permits are free either way. What costs time is finding them, one office and one search at a time.

Source: TarSignal, from North Carolina public building permit records, data through October 29, 2026. Refreshed nightly. Counts include every permit type a jurisdiction files — trade permits (electrical, plumbing, mechanical) as well as building permits — so one project can appear more than once. Values are what the applicant declared, where the jurisdiction records one. We keep improving how we collect each office's permits, so a count that steps up suddenly usually means more complete records, not more construction.
