How B2B teams use permit activity

Suppliers, software vendors, and market researchers can use permit activity to identify businesses associated with recent work. The source record does not measure workmanship, customer satisfaction, or contractor suitability.

Activity is source-published. A listed business is associated with available public permit records, rather than a paid placement.
Counts are scope-specific. They reflect this city's available permit inventory and the selected date window, not all of a contractor's work.
Fields vary by jurisdiction. Public sources may omit a contractor, owner, address, cost, or contact field on any given record.

Use the St. Louis, MO permit feed to review the actual available records, source date, permit types, and fields for this market.

For solar contractors: how to land on this list

If you run a solar business in St. Louis, MO and don't see your company name here, it usually means one of two things:

You haven't pulled a permit in the last 180 days under your registered business name.
Your permits are filed under a homeowner's or licensee-individual's name rather than your business — which happens a lot in jurisdictions like St. Louis, MO where the city permit system captures the licensee, not the firm.

Both are fixable. PermitGrab is built for the contractors on this list — daily permit alerts in your zip codes, owner phones where available, and a flat $149/mo with no annual contract. See how PermitGrab works for solar contractors in St. Louis, MO →

Frequently asked

How is this ranking calculated?

We count every solar building permit filed in St. Louis, MO over the last 180 days, group by contractor business name, and sort descending. No editorial weighting, no paid placements. The raw count is the rank.

Where does the permit data come from?

St. Louis, MO's official permit portal. PermitGrab pulls daily — most permits show up within 24-48 hours of issuance. The full underlying records are visible on the St. Louis, MO permit feed.

Is this better than Yelp or Angi reviews?

For one question — "is this contractor real and currently doing work?" — yes, by a wide margin. Reviews are great for catching catastrophic bad actors but can be gamed; permits are official-record proof of activity. Use both.

Why is contractor X not on this list?

Either they haven't pulled a permit in the last 180 days under their business name, or their permits filed under a licensee-individual's name instead. Both are common. The full search interface is on the St. Louis, MO permit page.
