## Inspection Requirements Inspections are required by law. Inspections help to establish that the deck has been built in accordance with the structural and safety provisions of the [Virginia Uniform Statewide Building Code (VUSBC)](https://codes.iccsafe.org/category/Virginia?year%5b%5d=Current+Adoption&page=1) standard construction practices and the approved drawings or the [Loudoun County Typical Deck Detail (PDF)](https://www.loudoun.gov/DocumentView.aspx?DID=878 "Loudoun County Typical Deck Detail"). An electronic of paper copy of the approved plans or typical deck detail must be on the job site and available to the inspector or no inspection will be performed. ### When Inspections are Required Three inspections, conducted by Loudoun County inspectors, are required for a deck: * Footing Inspection: footing holes are inspected prior to concrete placement. * Framing Inspection: joists, beams, connections and mechanical attachments are inspected prior to placement of decking. * Final Inspection: all remaining items are inspected. The framing and final inspections may be combined if all portions of the deck framing and mechanical attachments are at least 42 inches above grade. ## Schedule Inspections The permit holder or their representative must schedule an inspection when the stages of construction that require an inspection are reached. Inspections must be scheduled one work day in advance. * [Schedule an inspection in LandMARC.](https://www.loudoun.gov/landmarc)View official source
