Rules
3 Denver signage laws that affect outdoor local promotion
Denver signage laws set size limits, permit rules and temporary sign deadlines that shape outdoor promotion, so plan lead times and paperwork early.
What to take away
- Denver signage laws decide three things for a storefront promotion: how large a sign can be, what you must file, and how long temporary signs stay up.
- Denver sign size limits are set by the zone district, so a wall sign allowed on a commercial corridor can be too large on a residential block.
- Denver permit requirements mean a zoning permit for the sign, plus building and electrical permits for structural or illuminated signs.
- Temporary sign rules in Denver run on a fixed permit window, so banners and A-frames come down when the permit expires.
- Permit lead times of several weeks push sign ordering ahead of the launch date, and compliance documentation shortens the conversation if a sign is questioned.
The Denver signage rules that most often catch small businesses
Denver writes its own sign rules. The Denver Zoning Code, Article 10, governs signs, and the Community Planning and Development department issues the permits. Aurora, Lakewood and Englewood each run separate codes, so an approved sign nearby proves nothing about your block.
Three parts of the code cause the most trouble. Size and placement limits decide what you can put up. Permit requirements decide what you must file first. Temporary sign rules decide how long a banner or A-frame board can stay outside.
Enforcement usually starts with a complaint from a neighbor, a competitor or a passerby. An inspector then compares your sign against the approved plan set and the standards for your zone district.
Denver's Landmark Preservation Commission reviews signs in the city's designated historic districts, and that review adds time. If your storefront sits in one, treat the sign as a design project rather than a purchase.
Federal advertising rules can touch a promotion as well. The Federal Register business and industry topic tracks federal rules that affect advertising and business operations, and the Federal Register topics index helps locate rules on advertising and business when a campaign crosses state lines.
Rule one: size and placement limits for outdoor signs
Denver sign size limits come from the zone district rather than one citywide number. Article 10 ties a wall sign's allowed area to the building wall, and the ratio is more generous in commercial and mixed-use districts than in residential ones.
In practice, storefront wall signs along Denver commercial corridors usually land between about 20 and 60 square feet, set by frontage and wall height. Freestanding signs are limited by height and setback instead, and those caps tighten next to residential blocks.
Placement is checked just as closely. Signs cannot block sight lines at intersections, cover windows needed for emergency egress, or extend into the public right of way without separate approval. Projecting signs need clearance over the sidewalk, and many districts restrict or bar roof signs.
Overlay districts can tighten the numbers further. A design overlay or historic district may require a smaller sign, a specific material, or an externally lit sign instead of an illuminated cabinet.
Measure the wall or pole before you call a fabricator. A shop that orders a 48 square foot sign for a storefront that allows 30 has bought itself a violation.
If your promotion leans on a sandwich board rather than a permanent sign, the rules change. Our guide to sidewalk sign promotion covers how to keep a board legal and visible.
| Sign type | What usually triggers review |
|---|---|
| Wall sign | Area relative to the building wall and zone district |
| Projecting sign | Clearance over the sidewalk and projection distance |
| Freestanding sign | Height, setback and lot frontage |
| Roof sign | Restricted or prohibited in many districts |
| Temporary banner | Permit window, size and attachment method |
Rule two: permit requirements and review timelines
Denver permit requirements start with a zoning permit for the sign itself. Structural signs also need a building permit, and illuminated signs need an electrical permit and a licensed electrical contractor.
Fees follow the valuation of the work. A simple flat wall sign usually lands in the low hundreds of dollars once zoning and building fees are added. A large illuminated or projecting sign costs more because the permits stack.
Applications go through the city's online permitting portal. Expect to upload a site plan, dimensioned drawings of the sign, material and attachment details, and the installer's license number.
Denver review has two gates rather than one. A completeness check comes first, and a plan set missing dimensions or a site plan is sent back before a reviewer reaches the design. Zoning review then runs ahead of design or historic review.
Plan on roughly two to four weeks for zoning review alone, longer when an overlay, historic review or a resubmittal is involved. From application to a sign on the wall, four to six weeks is a realistic Denver timeline.
Start the permit before you commit to a launch date. A promotion tied to one weekend can be derailed by a resubmittal request.
The Small Business Administration's guidance on managing your business is a reasonable place to start when you fold compliance into routine operations.
Rule three: temporary signs, banners, and sidewalk displays
Temporary sign rules in Denver cover banners, pennants, A-frame boards and inflatables, and they run on permits with a clock attached.
Denver issues temporary sign permits for a set window rather than indefinitely. A banner for a grand opening or a sidewalk sale is generally approved for a few weeks, and the city limits how many days per year a property can run temporary signage.
Leaving the banner up after the window closes turns a permitted sign into a violation, even though nothing about the sign itself changed.
Some zone districts allow a small temporary sign for a short period without a separate permit. Others do not, so ask before you hang anything.
Sidewalk displays need to leave a clear path for pedestrians, including people using wheelchairs. Blocking the walkway is the fastest route to a complaint.
If you plan several temporary signs at once, count them together. A cluster of boards and banners can exceed the allowance even when each piece is small.

Planning a promotion calendar around permit lead times
Work backward from the promotion date. Zoning review, fabrication and installation each take time you cannot compress at the end.
- Fix the promotion date and subtract six weeks for zoning review, fabrication and installation.
- Look up your zone district and any overlay or historic designation on the property.
- File the zoning permit through Denver's online portal with a site plan and dimensioned drawings.
- Order the sign only after zoning approval, and hold the building and electrical permits for the signs that need them.
- Book installation and the city inspection, then photograph the finished sign for your file.
A bakery planning a fall launch on Tennyson Street files zoning paperwork for a 24 square foot wall sign, waits out review, then orders fabrication and books the electrical inspection for the same week as installation.
Keep a week of buffer before the event. A shorter banner run is easier to absorb than a pushed launch date.

What to document if a sign is questioned
Keep one file per sign. For a permanent sign, that means the approved zoning permit and its number, the stamped plan set, the building and electrical permit cards, the installer's license number, and the inspection sign-off.
For temporary signs, write down the permit window and the dates the sign went up and came down.
- Approved zoning permit letter and permit number
- Stamped plan set with dimensions and materials
- Site plan showing placement on the property
- Building and electrical permit cards for structural or lit signs
- Installer name and license number
- Inspection sign-off and photos from the street
- Start and end dates for any temporary sign
If you are unsure whether a sign needs a permit, ask before installing. A removal order costs more than a phone call.

Common questions
Do I need a permit for a small wall sign in Denver? Most permanent signs need a zoning permit, and the area allowed depends on the zone district. Check the district before you order.
How long does a Denver sign permit take? Zoning review alone usually runs about two to four weeks, and a resubmittal restarts part of that clock. Four to six weeks from application to installation is realistic.
Can I put an A-frame sign on the sidewalk? Often yes, if it leaves a clear pedestrian path and fits the size and placement rules. Denver also limits how long a temporary sign can stay up.
How long can a banner stay up? Temporary sign permits run for a set window, generally a few weeks, and the city caps how many days per year a property can display temporary signage.
What if a neighbor complains about my sign? Pull the permit, the stamped drawings and the photos. Documented compliance resolves most complaints without a fine.
Does a federal rule ever apply to my local sign? Rarely for a storefront sign, though federal advertising rules can apply to certain promotions. The Federal Register topics index is a useful reference.
