Building Codes
Fairfax County is required to enforce the Virginia Uniform Statewide Building Code (USBC) and the Statewide Fire Prevention Code (SFPC). Both codes are administered by the Virginia Department of Housing and Community Development and reference the 2012 International Codes as published by the International Code Council. Fairfax County Land Development Service’s Building Division has been awarded the highest achievable rating for building code effectiveness under the current Virginia USBC. Read more.
