What we ship
Colorado licenses electricians statewide through the State Electrical Board, at the master, journeyman and residential wireman levels, and every electrical contracting business must register with the board and have a licensed master electrician supervising all of its electrical work.
In Denver, most signs need a zoning permit and a building permit with structural plans stamped by a Colorado-registered structural engineer, plus an electrical permit for anything lit. The building permit must follow within 180 days of the zoning permit.

Who can install it
For a lit storefront sign, ask the registered electrical contractor who will connect the sign and who will supervise the work. The State Electrical Board licenses master and journeyman electricians for this type of work. The residential wireman credential covers wiring in one- to four-family dwellings. Colorado updated the experience and training rules for new electrical license applicants in 2025; the General Assembly summarizes those changes below.
Any business acting as an electrical contractor must register with the board and show workers’ and unemployment compensation compliance. If an owner holds a master license and supervises the work, that person can be the registered master; otherwise the contractor must employ at least one licensed master electrician to supervise all electrical work, and a master can qualify only one contractor at a time.
| Licensing agency | Colorado State Electrical Board, Division of Professions and Occupations |
|---|---|
| Commercial wiring | Licensed master or journeyman electrician |
| Residential wireman | One- to four-family dwellings |
| Contractor | Board registration; a licensed master supervises all electrical work |
Rules change. Always confirm with the office that issues your permit before you order.
Permits
Colorado cities and counties issue sign permits under their own codes, and Front Range suburbs and mountain towns each set their own size and lighting limits.
In Denver, Community Planning and Development requires a zoning permit for most signs on private property. The application includes a site plan with dimensions from the sign to the zone lot lines and a fully dimensioned elevation showing the sign on the facade and its height above grade. A building permit is also required for most signs unless the Denver Building and Fire Code exempts them, with structural plans for the framing, supports, connections and anchorage that are prepared, stamped and signed by a Colorado-registered professional structural engineer.
Applications go through Denver’s e-permits system; choosing a building log gets the zoning and building reviews done together. If the building permit isn’t obtained within 180 days of the zoning permit, the zoning permit has to be applied for again. A sign with electrical components needs an electrical permit, one that crosses into the public right-of-way needs a Department of Transportation and Infrastructure permit, and a sign on a landmark or in a historic district goes to Landmark Preservation for a Certificate of Appropriateness.
| Sign permit | Your city or county |
|---|---|
| Denver zoning | Zoning permit with site plan and dimensioned elevation |
| Denver building | Structural plans by a Colorado-registered structural engineer |
| Denver timing | Building permit within 180 days of the zoning permit |
| Denver lit signs | Electrical permit as well |

Banners and temporary displays
Denver allows a temporary commercial sign promoting an event, sale or service of the business on the same lot for up to 45 days without a permit. That covers an unlit window sign, a wall sign or poster, window graphics, and banners with commercial copy; if a temporary window sign will be lit, it needs an electrical permit. Inflatables, balloons, streamers and pennants for a special event do need a permit, and every temporary sign still has to follow Section 10.10.3 of the Denver Zoning Code.
Weather
Colorado’s high-altitude sun is intense, Front Range summers bring hailstorms, and downslope chinook winds can gust hard along the foothills. Choose UV-stable face colors, and ask your installer to anchor letters for wind and snow load.
