Building codes are adopted at the state or local level typically on a three- to six-year timeframe. However, most building codes are developed on a consistent three-year cycle as “model” codes with the intent that they can be amended by the jurisdiction prior to adoption.
NAHB members and staff participate in the code development process to make the codes as usable and affordable as possible. However, some changes are incorporated into the codes that NAHB does not support.
NAHB has developed Code Adoption Kits to assist state and local HBAs during the code adoption process to better explain the implications of the new codes. These kits also include amendments to address issues identified by NAHB members and staff.
Jurisdictions often amend the code before adopting the model codes to take into account local considerations, such as geography, climate and local practices. NAHB has developed suggested amendments that may improve the model codes adopted in your jurisdiction. For help, please contact the NAHB Construction Codes and Standards staff member in your area.
