Access is required for gas equipment on roofs when the building height exceeds how many feet?

Explanation:
Access to roof-mounted gas equipment is required when the building height exceeds 15 ft. This threshold ensures a safe, reliable way to reach and service equipment such as valves, regulators, and vents on the roof. Providing a proper means of access (like a permanent stair or ladder) helps workers perform inspections, maintenance, and emergency shutoffs without unsafe climbs or improvisation. At 15 ft or less, the code does not mandate a dedicated roof-access arrangement for this equipment, which is why 15 ft is the correct limit.
