The International Building Code (IBC) and International Residential Code (IRC) are written and administered by a group called the International Code Council (ICC).
These codes cover commercial and residential building and remodeling. Both are available online for a charge and portions are available for free.
IBC vs. IRC vs. ICC: Sorting Out the Alphabet Soup
- ICC: The ICC is in charge of a wide range of codes that will not apply to your home remodel or build (or only slightly), such as codes for property maintenance, swimming pools and spas, fuel gas, sewage, and many more. But a number of codes do apply--the IBC and IRC.
- IBC: The International Building Code contains regulations about commercial construction
- IRC: The International Residential Code contains about residential construction (which also touches on home remodeling issues).
Model vs. Local Building Codes
The IBC are IRC are model codes for building structures that communities can adopt and adapt in-part as needed. They are not legal as-is.
If you want to lay a floor in Tallahassee or hang drywall in Poughkeepsie--whatever you are doing home remodeling-wise--chances are good that your local actions are dictated by these international codes.
Consulting the IBC or IRC may not necessarily apply to that floor in Tallahassee (but it might, since some municipalities adopt the code in-whole).
Only after a community adopts a building code does it become legal.
