The current Uniform Statewide Building Code (USBC) went into effect on September 4, 2019, which now requires mechanical testing for air leakage in duct-work. See below for more details on the USBC regulatory process.
On December 16, 2019, the Department of Housing and Community Development (DHCD) Board voted to approve the draft 2018 USBC, which included blower door testing for all new construction. On December 14, 2020, the Board voted to adopt a final draft of the USBC, which includes blower door testing and increased insulation requirements for ceilings. The final draft is anticipated to go into effect sometime in Quarter 3 of 2021. The 2021 update process is not expected to begin until after this final draft is in effect.
Virginia Regulatory Process
Before Virginia begins the process to update the state building code, the model code is updated at the federal and international level. The International Code Council (ICC) is a membership-based organization that produces an updated model code every three years (2015, 2018, 2021, etc.). While states are not mandated to use the model code, many use it as a starting point to develop their own state code, like Virginia, while other states adopt the model code as is, such as Maryland. For even more details on the energy code process at the federal level, DOE has a great blog post detailing each step.
Virginia’s building code is known as the Uniform State Building Code (USBC). The Department of Housing and Community Development oversees the two-year code update process, which includes stakeholder input, public meetings, and board actions. The Board of Housing and Community Development is comprised of 14 members representing each of Virginia’s 11 congressional districts and three ex-officio members representing the Virginia Fire Services Board, the Virginia Building Code Officials Association, and the Virginia Housing Development Authority. Each member is appointed by the Governor to 3-year terms with a two-term limit. Historically, this board has been comprised entirely of home-builders. However, over the last several years, building science experts and community development advocates have also been appointed to the Board.
The diagram below explains the two-year USBC update process:
The update process begins with proposal submissions via the DHCD codes portal. Anyone can submit a proposal to the portal. Proposals are reviewed by open, public workgroups and voted on by those in attendance. Proposals move forward to the next phase of the process with a workgroup recommendation of either consensus, non-consensus or rejection. It only takes one “no” vote for a proposal to be marked as non-consensus. All proposals are then reviewed by the DHCD Board Codes and Standards committee, which also makes recommendations to the full Board. The full Board then reviews all proposals and votes to adopt either the draft (year one) or final (year two) USBC. This process is repeated both years. Once the final USBC is approved by the Board in year two, it goes to the Attorney General and the Governor to sign off as well. Once the updated USBC goes into effect, there is a one year grace period before it is enforced.
Additionally, there are several comment periods and public hearings throughout the two-year process.
