Step 1: Search the Durham City-County Land Development Office site (free)
The permit office's own records, straight from the source. Search for: residential alteration, addition and repair.
- Search permits by address or permit number, or browse by date where the search allows.
- Each permit lists its type, status and inspections.
- Durham also posts monthly construction activity reports on durhamnc.gov.
Who's on a permit: Permits name the contractor; phone numbers aren't shown.
Step 2: Keep the permits worth a call
Does the work need a permit in North Carolina? Usually not. Replacing windows, doors or siding costing $40,000 or less is exempt; new or enlarged openings aren't. So these are the window, door and siding permits on file, and what each is worth.
New homes and additions
Every new house and most additions need windows, exterior doors and siding. The builder or general contractor on the permit chooses the supplier and installer.
Storm and structural repairs
Repairs after a storm or a fallen tree often take windows and siding with them, and clusters of them mark the streets that were hit.
Remodels
A whole-house renovation usually replaces windows and doors as part of a larger job, with a general contractor to call.
Step 4: Know who's pulling them
Most like-for-like replacements are exempt from permits, so the window and siding companies here are only part of the market. The builders and remodelers are your customers. Ranked by permits in the last 12 months.

Source: TarSignal, from North Carolina public building permit records, data through October 28, 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.
