Step 2: Keep the permits worth a call
Does the work need a permit in North Carolina? Yes, for structural work. Foundation repair is load-bearing work; a slab or patio that carries nothing usually isn't. So these are the foundation and concrete permits on file, and what each is worth.
New homes
Every new house needs footings, a foundation and flatwork. The builder on the new-home permit picks the concrete sub, often for a whole community.
Foundation repairs
A permit for piers or crawlspace work is a job already sold, but the repair companies filing them show where soils and older homes keep producing work.
Retaining walls and site work
Retaining wall permits come with new subdivisions and commercial sites, where the developer or site contractor hires.

Source: TarSignal, from North Carolina public building permit records, data through October 6, 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.
