Stairs and ramps are regulated for safe movement and accessibility. Code focuses on geometry (riser height, tread depth, ramp slope), handrails/guardrails, landings, headroom, and slip resistance. For accessibility, ramps often must meet maximum slope and landing rules; stairs must meet uniform riser/tread requirements to reduce trips and falls. Worked example(s) Example: A non-uniform stair where one riser is taller than the others is a common trip hazard; codes limit riser variation within a flight.
