Sign Permit in Unincorporated Washington County, Colorado
Unincorporated Washington County publishes no dedicated local sign-permit application, sign ordinance, or sign fee schedule anywhere online — checked directly against the current Planning & Zoning department webpage and the Planning and Zoning Forms page, both of which list only Building/Foundation/Mobile-Home permits, USBR (Use by Special Review) and its amendment/extinguishment forms, Subdivision Exemption, Temporary Use, Road Access/Road Cut, Petition for Vacation, Address Request, and similar land-use forms — no sign-specific document appears among them. The County's own Zoning Resolution is confirmed to be currently in force (see localAmendments elsewhere in this file) but is not published online anywhere reachable, so it could not be checked directly for any on-premise sign standard it might contain. The one sourced, applicable sign-permitting mechanism confirmed to reach unincorporated Washington County is the Colorado Department of Transportation's (CDOT) statewide Outdoor Advertising Permit program, which regulates OFF-PREMISE advertising devices (billboards) within CDOT's 'control area' adjacent to the state highway system under the Colorado Outdoor Advertising Act (C.R.S. Title 43, Article 1, Part 4) — state highways cross the county's unincorporated area. That state permit application requires Part 3 to be completed and signed by 'the representative of the local jurisdiction' (i.e., Washington County) certifying the site's zoning classification and compliance with local ordinances, giving the County Land Use Office a real, sourced role even though CDOT itself issues the permit.

When you need this permit
- No dedicated local sign-permit application or fee schedule was found published anywhere on Washington County's website — confirmed directly against both the current Planning & Zoning department page and the Planning and Zoning Forms page, which list every other land-use form the County publishes (Building Permit, Foundation Permit, Mobile/Manufactured Home Permit, USBR and its Amend/Extinguish forms, Subdivision Exemption, Temporary Use, Road Access, Road Cut, Petition for Vacation, Request for Address) with no sign-specific item among them
- For an OFF-PREMISE advertising sign (a sign advertising an activity/product/service not conducted on the property where the sign sits) located within CDOT's 'control area' adjacent to the state highway system, a CDOT Outdoor Advertising Permit Application (Form #291) must be filed with CDOT's Outdoor Advertising Program
- Part 3 of CDOT Form #291 must be completed, signed, and dated by a representative of Washington County certifying the sign site's current zoning classification (commercial or industrial classification required, or an 'other' classification shown to encompass commercial/industrial use) and certifying compliance with all applicable County ordinances, variances, plans, rules, and other requirements
- Permit fee is set by statute per sign face area, per C.R.S. § 43-1-409(1)(b): $10.00 (100 sq ft or less), $20.00 (101-250 sq ft), $40.00 (251-600 sq ft), $75.00 (601 sq ft or more)
- Permits are issued for a one-year term (July 1-June 30) and must be renewed annually before June 1 with payment of the renewal fee, per C.R.S. § 43-1-409(1)(a)-(b); a late fee applies to renewals submitted after the deadline
- ON-PREMISE business signage (a sign advertising the business/activity located on the same property as the sign) is not addressed in any Washington County document found online; whether the County's own (unpublished) Zoning Resolution separately regulates on-premise signs could not be confirmed or ruled out — contact the Land Use Office directly, (970) 345-2701 ext. 234, before erecting an on-premise sign

Tips
- Washington County has no sign-specific form of its own — if you're putting up a roadside/off-premise advertising sign near a state highway, the permit is issued by CDOT, not the County, though the County's Land Use Office must still certify your site's zoning on Part 3 of the CDOT application.
- If your sign is on-premise (advertising your own business at its own location) rather than roadside off-premise advertising, no dedicated county sign permit or fee was found online — call the Land Use Office, (970) 345-2701 ext. 234, before you build, since the County's own Zoning Resolution (unpublished online) may still contain applicable standards.
