How does the tool ensure building code compliance?

The tool uses `calculate_stair_geometry` to check dimensions against IRC/IBC limits, such as maximum riser height and the stride rule.

Can I check if my stairs have enough headroom?

Yes, by using the `check_clearance_and_headroom` tool, you can validate vertical clearance against the minimum 6'8" requirement.

What stair types are supported?

The calculator supports straight, l_shaped, u_shaped, and spiral stair configurations.

This MCP server provides precise stair design calculations based on strict building codes like IRC and IBC. Use calculate_stair_geometry to determine riser heights, tread depths, and total run lengths. You can also use check_clearance_and_headroom to ensure vertical safety and validate_landing_requirements to confirm if your staircase layout needs a landing. It flags code violations automatically to ensure safe and ergonomic stair construction.
