Delaware Building Permits

Three counties dominate; municipalities may opt-in.

How Building Permits Work in Delaware

Delaware's state government acts as an enabling authority but does not manage a statewide permit system. The state allows its three counties to serve as the primary permitting agencies for unincorporated land, while granting incorporated municipalities the power to opt-in to their own independent permitting processes.
