State Statutes and Adopted Codes

Building regulations in Virginia are governed by the Virginia Uniform Statewide Building Code (USBC). The USBC establishes the minimum requirements for the design, construction, renovation, and maintenance of buildings, including heating, ventilation, and air conditioning (HVAC) systems. As of January 18, 2024, Virginia has adopted the 2021 editions of the International Codes (I-Codes) as the basis for the USBC. These include the Virginia Construction Code (based on the International Building Code), the Virginia Residential Code (based on the International Residential Code), the Virginia Mechanical Code (based on the International Mechanical Code), and the Virginia Energy Conservation Code (based on the International Energy Conservation Code).

Primary State Board and Agencies

The Board of Housing and Community Development (BHCD) is the primary body responsible for adopting and amending the USBC. The board updates these codes every three years through a formal code development process that incorporates stakeholder input. The Virginia Department of Housing and Community Development (DHCD) administers these regulations and provides oversight for the code development process. Enforcement of the USBC is carried out at the local level by municipal building inspections departments.
