FAQs for Contractors and Code Officials

Frequently asked questions for construction contractors and building code officials

The website indicates no residential code in the area where I work as a home building contractor, but there are residential codes in communities just a few miles away. Why?

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.

What is the difference between the code status shown on the website for residential homes vs. commercial building construction?

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.

The website says we don’t have a residential code adopted, so do I still have to get a permit to build or remodel a home?

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.

Does the website reflect floodplain regulation information since the IRC includes floodplain construction criteria?

The website only addresses adoption, in part or whole, of the International Residential Code; it does not address floodplain regulations currently.

The website says that I do not have a residential code in our county, but it is my understanding we are not allowed to adopt or enforce a code at the local level.

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.

The website indicates that our code is not adopted or is out of date; however, we have updated our codes, so they should show as current.

Please email info@flash.org to provide feedback on current code statuses in your jurisdiction or community. Once we receive your input, we will verify it and input it into our database as part of our monthly update process.
