The Automated Inspection Request System is designed to dispatch inspection requests for the next working day.

  • Available 24 hours daily.  
  • All inspections requested before Midnight will usually be scheduled for the following working day. Occasionally an inspection will be scheduled for a later date due to workload problems.  
  • Permit Number Needed: You need the permit number to use this system.
    This is the number printed on the bottom of your permit beginning with the year. For example, 98123456 would be the permit number which must be entered from your touch tone telephone pad when requested by the system.  
  • Inspection Code Needed:You need a three-digit code for the type of inspection you are requesting.
    This can be found on the Inspection Type Directory.  
  • You will be given a verification number and the inspection date at the end of your call if all the information you enter is correct. Please stay on the line until you get that number.
