Even jurisdictions that are close in geographic proximity can have different local ordinances, and this can cause confusion and add cost for homebuilders. Statewide adoption of current codes creates consistent construction requirements, training needs for homebuilders, and home quality for consumers.
The International Residential Code (IRC) is applied to new residential construction, while the International Building Code (IBC) applies to all other new construction, including commercial buildings. Most single-family housing is constructed using the International Residential Code, while the International Building Code governs other residential structures, such as multi-family buildings like apartments and some townhomes.
Local rules or ordinances may require construction permitting even if a residential code is not adopted. Local rules are often less restrictive than the International Residential Code provisions, which incorporates the benefits of updated construction methods, research, and innovation.
The website only addresses adoption, in part or whole, of the International Residential Code; it does not address floodplain regulations currently.
States have different laws regarding building code adoption and enforcement at the local level. Contact your local government leaders, the relevant state department, or other authority to learn more about building code adoption and enforcement details in your community.
