Online & Phone System


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, please visit the online ePortal at or call the Automated Phone System at 1-866-457-5280 to:

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

Both systems are available seven days a week, including holidays.

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.
