Building and Trade Inspections

Effective March 23, 2020: Due to the COVID-19 outbreak, many building and trade inspections can be completed virtually. In-person inspections are available on Tuesday and Thursday only. All others have been postponed. View all building-related service changes here.

Once your permits have been approved, you must schedule building and trade inspections to ensure the safety and proper progress of the project. It is the responsibility of the permit holder or the permit holder’s representative to schedule inspections.

Ladders, scaffolds, and testing equipment required to complete inspections must be provided by the permit holder. The person or team present for any inspection must have copies (paper or digital) of all approved plans and support documentation (approved permit, plat, building plans, placards, etc.).

Notify Miss Utility at least 48 hours prior to beginning any excavation work: 1-800-257-7777.

NOTE: To schedule an inspection for a Fence/Retaining Wall or Wall Permit, Sign PermitDemolition Permit or an Amusement Device Permit, you must use the Permit Arlington customer portal.

Canceling or rescheduling an inspection on the inspection day will result in a re-inspection fee and prevent you from scheduling additional inspections.
