To build an addition or garage, you will need construction plans. The plans should have a plan view looking down, a cross section, and elevations. If you are using trusses, indicate so on your plans. If rafters and ceiling joists are used, provide a roof framing plan with the size and spacing of framing members. Steps 1-3 may be completed at the Development Services Building, 5 County Complex Court, Prince William, VA, 22192. Step 4 may be completed by telephone or online.
