Proposed structure area (ft²)

Screening result

Enter the site dimensions, then run the check.

Published rules represented

The checker models the 2024 IBC Section 424 height/area trigger, the U.S. Access Board’s 60-in ground-route rule and 44-in small-play-area exception, and CPSC Publication 5065’s 17–28 in cargo-net opening-perimeter alert. Local adoption and full clauses control.
