A BuildVerify360 product for builders
Check the set before the city does.
Upload a cover sheet and site plan. We read the dimensions, bind them to that city's adopted code, and return cited findings. The city still decides.

How it works
Pick a city
Choose the jurisdiction that will review your permit. Pre-Flight loads the adopted code library for that city.
Upload the set
Drop a cover sheet and site plan (under 20 MB). Pre-Flight runs vision on the drawing and pre-fills the project data.
Verify & get cited findings
Confirm the extracted dimensions, then run the review. You get pass / flag / critical findings tied to municipal sections.
A cited finding
Skokie R-1 side yard · proposed 2.75 ft · required 6 ft · Sec. 118-124 · Critical
Adopted code Pre-Flight checks
Pre-Flight checks your set against the adopted municipal code for each city — plain-English summaries of the rules it carries, linked to the official source.

| Which code? | Whatever it remembers or browses | Adopted library for the city you pick |
| Citations | Often generic IRC | Municipal section tied to that AHJ |
