Normally, two inspections are required for a Residential Permit, a Close-in and a Final inspection. If this is a Close-in inspection or Final inspection for a residential permit, the Building permit and the Mechanical must also be scheduled for the same date. Installers may call 311 or go to the DPS website , under eServices, and click DATA SEARCH to schedule, or cancel a mechanical inspection. Generally, requests before 12:00 PM on any given day will result in an inspection on the next business day. Inspection codes for mechanical inspections are as follows: Residential Close-in 008; Residential Final 251; Commercial Close-in 608; Commercial Final 651.
