Douglas County, CO Sign Regulations: Freeway-Facing Signs (2026)

Part 29 of the Land Use Regulations flatly prohibits billboard signs anywhere in the unincorporated county: § 1-2904, Subsection 2 makes it unlawful to erect, maintain, or continue the use of any billboard sign. That ban applies regardless of frontage on I-25, US-85, or any other freeway or highway. For freestanding signs that are otherwise lawful, § 1-2907 layers on a heightened setback near major roads: while the baseline setback from any property line is 10 feet, a sign adjacent to a federal, state, or major County arterial highway must sit back a minimum of 75 feet from the lot line adjacent to that highway's right-of-way.

That 75-foot setback can be reduced only under Table A, and only if adequate right-of-way has already been dedicated for future road widening and the agency controlling the right-of-way has given written approval. Sign height is rounded to the nearest foot to determine the Table A setback that applies. Freestanding signs are separately capped at 15 feet in height under § 1-2906. B.
