The 2006 International Residential Code is a comprehensive, stand-alone residential code that establishes minimum regulations for one- and two-family dwellings of three stories or less. It includes all building, plumbing, mechanical, fuel gas, energy and electrical provisions for one- and two-family dwellings.
The provisions of the 2006 International Residential Code apply to the construction, alteration, movement, enlargement, replacement, repair, equipment, use and occupancy, location, removal and demolition of detached one- and two-family dwellings and townhouses that are not more than three stories above grade with a separate means of egress and their accessory structures.
The 2006 International Residential Code is intended to provide minimum requirements to safeguard public safety, health and general welfare through affordability, structural strength, means of egress facilities, stability, sanitation, light and ventilation, energy conservation and safety to life and property from fire and other hazards attributed to the built environment.
