Building Inspections

COVID-19 Update Regarding Inspections

On July 1, 2020, Building and Development will resume in-person building and trade inspections. Virtual inspections will no longer be performed.

All inspectors will be required to wear face coverings and maintain a safe distance from others. Whenever possible, inspectors will ask to be directed to the entrance closest to the work needing inspection to avoid walking through a residence. 

Inspections that were not eligible for the virtual inspection process, such as gas inspections in occupied residential structures, can be scheduled for on or after July 1, 2020. 

Customers may schedule all inspections through the Web Automated Inspection Request System (WAIRS). 

For questions, please call Building and Development at 703-777-0220, and select option 1.
