It is the responsibility of the owner or designated representative to call for inspections as construction proceeds.  Failure to call for inspection at the appropriate time may result in project delays.  All work to be inspected must be visible and not concealed by further construction.

When requesting an inspection please provide the permit number, site address and owner’s name as well as the type of inspection required.  We require at least three business days notice to be able to schedule your inspection.

Permit documentation must be on site for each inspection and made available to the Building Official, please also ensure that the permit identification sign is posted so it is clearly visible from the road.
