Sign Permit in Unincorporated Natrona County, Wyoming
Required for installation, replacement, or alteration of any building or freestanding sign in unincorporated Natrona County, unless specifically exempted. Reviewed jointly: the Natrona County Building Department processes the physical Sign Permit application (form-based, same combined valuation-based fee table as other trade permits), while the Natrona County Planning Department separately certifies zoning compliance under Zoning Resolution § 5.13 Sign Permit, applying the sign standards of § 3.08 Signs (size, height, setback, and district-based cumulative area limits).

When you need this permit
- Natrona County Building Sign Permit application submitted to the Building Department, specifying whether the sign is New, Replacement, or Repair
- Type of sign identified: Building Sign, Free Standing Sign, Billboard, Roof, Canopy, Projecting, or Other, plus whether the sign has electrical service
- Sign dimensions (width, length, height) and mounting height (distance from ground to top and bottom of sign) must be provided
- Job valuation of the sign work must be declared for fee calculation under the county's combined valuation-based fee table
- Sign must comply with Zoning Resolution § 3.08 Signs: freestanding/pole signs are limited to 40 ft in height and 100 sf in area per lot (one per lot, or a second up to 50 sf if the lot fronts two public streets, with 150 ft spacing from other freestanding signs), and total cumulative sign area is capped per the district-based Table 3.08-1 (based on lot road frontage and zoning district: RAM/UA, MR-1/MR-2/RR/SR/UR/UMR/MH, or C/LI/HI)
- Certain sign types are exempt from the Sign Permit requirement per § 3.08(B)(2), including government signs, one wall sign up to 16 sf, cornerstones, historical markers, window displays of actual merchandise, and specified temporary signs — confirm exemption eligibility with the Planning Department before assuming a permit is not needed
- Billboards (off-premise signs) require a Sign Permit issued by the Planning Department, are only allowed in the RAM, UA, C, LI, and HI zoning districts, must not exceed 680 sf (over 480 sf requires a Conditional Use Permit in C/LI/HI), may not exceed 50 ft in height, and require a landowner-authorization letter
- Electrical work for an illuminated sign requires coordination with the county's Electrical Permit process in addition to the Sign Permit

Tips
- Not every sign needs a permit — Zoning Resolution § 3.08(B)(2) exempts government signs, one wall sign up to 16 sf, cornerstones, historical markers, window displays of actual merchandise, and several temporary sign categories; confirm your specific sign against the exemption list before applying.
- Freestanding/pole signs are capped at 40 ft in height and 100 sf in area per lot — a second freestanding sign (up to 50 sf) is only allowed if your lot fronts two public streets, and it must sit at least 150 ft from any other freestanding sign on the same or adjoining property.
- Total cumulative sign area on a property is capped by Table 3.08-1 based on your lot's linear road frontage and zoning district — commercial/industrial (C, LI, HI) districts get the most generous allowance, residential/agricultural districts (RAM, UA, MR-1, MR-2, RR, SR, UR, UMR, MH) are more restrictive.
- Billboards are a separate, more heavily regulated category: permitted only in RAM, UA, C, LI, and HI districts, capped at 680 sf and 50 ft in height, and require a landowner authorization letter plus (over 480 sf in C/LI/HI) a Conditional Use Permit.
