Compliance for every project type
Most stair apps do the math and leave you to figure out the code. This one checks your design against the standards that apply to your project:
→ IRC — residential construction
→ IBC — commercial buildings
→ ADA — accessibility requirements
→ OSHA — workplace and industrial stairs
Each code set has different requirements for riser height, tread depth, and stringer geometry. Know exactly which rules apply and whether your design passes — before you cut a single board.
Customize for your jurisdiction
Local amendments override the defaults everywhere. Enter your city or county modifications so compliance checks reflect the rules that actually govern your project — not just the national standard.
For pros and DIYers alike

Contractors & builders: catch violations before the inspector does
Architects & designers: validate specs during design, not after
Safety officers: verify OSHA compliance on industrial stair layouts
Homeowners: build deck stairs confidently without guessing the code
