How Sign Permits Work in Delaware
In Delaware, business sign permits are issued by individual cities, towns, and counties — not by the state government. Each municipality adopts its own sign ordinance defining what signs require permits, what sizes and types are allowed in each zone, what fees apply, and what the review process looks like.
State law in Delaware establishes the outer boundaries: what municipalities can and cannot regulate, how outdoor advertising near state highways is governed, and what constitutional protections apply to signs. Within those boundaries, local governments set their own rules.
How to Find Your Sign Permit Authority in Delaware
- If you're in an incorporated city or town: Contact the city's planning, zoning, or building department. Search "Delaware [your city name] sign permit" to find the right office.
- If you're in an unincorporated area: Contact your county planning or building department. County rules apply in areas outside city limits.
- Near a state highway: Outdoor advertising signs (billboards) visible from state roads require approval from your state's department of transportation in addition to any local permits.
What Most Delaware Municipalities Require
