Permits & Inspections
How permitting works in Delaware
Delaware's three counties are the dominant permitting authorities in the state. Because there are relatively few incorporated municipalities, the county building departments handle the vast majority of all residential and commercial permit applications, plan reviews, and inspections for the state's population.
Three counties dominate; municipalities may opt-in.
