Once you’ve received the necessary residential permits, you must schedule inspections at certain points in the construction process. When you schedule an inspection, please have a copy of the approved permit, plat and building plans on the job site and available to the inspector during each inspection. It’s the responsibility of the permit holder or the permit holder’s representative to notify the County when the stages of construction that require inspection are reached. Ladders, scaffolds and testing equipment required to complete an inspection must be provided.
Call Arlington to schedule your inspection appointment 24 hrs in advance. Please have your permit number available when scheduling an inspection.
