Inspectors are responsible for setting their daily inspection schedule. Inspections should be requested no later than 3 p.m. the day before your inspection. Do not use your cellular phone to request an inspection - cellular signals are not reliable, possibly resulting in an incomplete inspection request with delayed or no inspections.
*Due to unforeseen delays, your inspector might not be able to complete the entire inspection schedule for that day.
