Schedule an Inspection


For more details on Inspection Scheduling - Automated Systems, see our handout: Guidelines to Using the Automated Plan Status & Inspection Scheduling Systems.

At various stages during construction, inspections must be performed by County staff to ensure the work has been done according to approved plans and building code requirements. 

To access the Automated Systems, go to eInspections online at or call the Automated Phone System at 703-792-6970 (touch tone users only) to:

      • Schedule Inspections
      • Cancel or Reschedule Inspections 
      • Obtain Inspection Results
      • Automated System for Plan Review Status and Comments

(Rotary telephone users may call Building Construction Inspections at 703-792-7006 to schedule inspections.) 

Both systems are available seven days a week, including holidays except for data back-up and maintenance nightly from 2 to 7:30 a.m.

Inspections must be scheduled by 3 p.m. on the work day prior to the desired date of the inspection. When requesting information or scheduling inspections from the automated phone system, the system will 'speak' back to you and provide important information: the permit number, the site address, and the type of inspection.  Please listen to this information carefully for verification.

Residential One- and Two-Family (IRC) Inspections for construction of new dwelling units, additions, alterations, and basement finishing using the IRC code are in the Combination Inspection Program. The inspection codes for combination concealment (198) and combination final (199) are under the Building heading.

To Obtain Inspection Results

You can also use either of the automated systems to learn the results of an inspection. On the Automated Phone System, press three (3) to obtain inspection results. Enter your permit number and the inspection code. The system is designed so that you can obtain inspection results shortly after the inspection has occurred. 

Note: All final inspections shall be approved before a certificate of use and occupancy will be issued. In addition to the above inspections, your project may require approval of one or more of the following areas prior to issuance of a certificate of use and occupancy.

Contact Virginia American Water at 703-491-2136.

4.  Site Inspection: A certificate of use and occupancy will not be issued until all site work has been completed. The inspection will ensure the work conforms to the approved site or subdivision plan. For more information call 703-792-7070.
