The Virginia Board of Housing and Community Development (a Governor-appointed board) has authority to adopt changes to the Uniform Statewide Building Code (USBC). The adoption process for modifications may take up to 12 months. Virginia is on a 3-year review cycle concurrent with the publications of new editions of the model codes. Virginia has consistently adopted the IECC published versions the past four code cycles. Virginia adopted the 2009 IECC, effective March 1, 2011, with a 1-year phase-in period during which builders and designers can still use the current USBC version.
