Nevada Building Codes: Stairs & Guards
Nevada has no single statewide residential code — the IRC edition and any amendments are set locally, and Clark County maintains its own amendments. Confirm before relying on any figure.
Nevada has no single statewide residential code. Building codes are adopted and enforced locally, and the IRC edition in force varies by county — Clark County/Las Vegas uses the 2018 IRC, Washoe County the 2024 IRC. The state’s Public Works division separately adopted the 2024 IRC, but only for state-owned projects.
Because Nevada is local-option, confirm both the IRC edition and any amendments with your local building department before relying on any figure — Clark County in particular maintains its own amendments. No specific Nevada stair or guard amendment is confirmed here; where a straight IRC edition applies, figures follow the IRC baseline. See the US stair & guard rules for the shared figures.
