Denver sign permit: what to file, in what order

By USSignCode Editorial · Last updated September 29, 2026 · How we check this page

Denver regulates signs by your zoning district — and getting a sign up usually means stacking several permits, not one. Add historic-district material rules and highway-corridor state rules, and a simple frontage calculator can't tell you what you actually need. Here's the real picture.

30-second risk check

No address, no measurements — just tap Yes or No. This flags where a Denver sign gets risky.

Do you know you may need a stack of permits (zoning + building + electrical) for one sign?

Is your building a designated landmark or in a historic district?

Will the sign use vinyl, plastic, or an internally-lit cabinet?

Will the sign extend above the roofline?

Will the sign be animated?

In Denver, the hard part isn't the size — it's the permit stack.

Your sign's allowed area is set by your zoning district under the Denver Zoning Code, and it varies from one zone to the next. But the bigger trap for new owners is that a single sign often requires a zoning permit, a building permit, and — if it's lit — a separate electrical permit. In historic districts you add a Landmark Preservation review on top. That's why Denver's own guidance points owners to a sign professional.

The permit stack you're actually facing

Depending on your sign and location, you may need several of these — confirmed in Denver's permit guidance and Colorado sign rules:

Zoning permit

Required for signs located on private property, and for private-property signs that extend over the public right-of-way (like an awning sign over the sidewalk).

Building permit

Required to physically install the sign.

Electrical permit

A separate permit required if your sign has any electrical components or connections.

Landmark approval

In a historic district, a Certificate of Appropriateness from Landmark Preservation is required before you can proceed.

How to apply for a Denver sign permit

The permits above are the what. This is the order they come in — each step decides what the next one needs.

1. Confirm your zoning district

Denver sets sign area per zoning district, so your allowance is unknown until the district is fixed. Everything downstream depends on it.

2. Historic / landmark check

If the address sits in a historic district, a Certificate of Appropriateness from Landmark Preservation comes before the build permits — not after.

3. Zoning permit

For signs on private property, and for private-property signs that extend over the public right-of-way.

4. Building permit

To physically install the sign.

5. Electrical permit

Separate permit, required if the sign has any electrical components or connections.

Fees

Denver publishes sign permit fees through its e-permits system, and the amount depends on which permits in the stack your sign triggers and on the valuation of the work. We do not reproduce a figure here because a stale fee is worse than none — confirm the current amount in Denver's e-permits portal (Denver Development Services) when you file, and budget for more than one permit fee if your sign is illuminated or in a historic district.

How long it takes

Denver does not publish a turnaround for a sign permit — no service standard, no target, no range — so this page gives no number. What it can tell you is which path is longer, and confirm with Development Services for your case:

Simple commercial sign

Shortest path: documents complete and the sign already complies. No week count — the City publishes none.

Historic district / design review

Longer, because a commission review is added to the permit path and commissions meet on a fixed calendar.

Why we quote no week count

The ranges this panel used to carry came from sign-industry guides, not the City. An unsourced range reads as a commitment Denver never made, so it is gone — ask Development Services for the current wait.

Timeline figures are secondary-source estimates, not City-published service standards. The permit stack itself (steps 1–6) is from official Denver and Colorado guidance.

The rules that catch people off guard

Sign area is set by your zoning district and varies by zone — there's no single citywide square-footage number.
Historic districts ban common materials: businesses in Denver historic districts generally cannot install vinyl signs (except window vinyl on glass), plastic signs, or internally illuminated cabinet signs. Wood, metal, and painted signs are preferred.
Roof signs that extend above the roofline are prohibited citywide, and animated signs are prohibited except in specific areas.
Many sites require a Comprehensive Sign Plan and a meeting with planning services before any signage goes up.
The Denver Theatre District and Business Improvement Districts route through their own coordinators and may restrict signs further.

⚠ Why a calculator can't give you a number

Denver's sign allowance lives inside zone-specific code that the city itself says is tricky to decipher — and your real cost is the stack of permits (zoning + building + electrical + possible Landmark review), not just the square footage. Getting the permit order wrong can stall your project for weeks. This is where a licensed Denver sign professional pays for itself.

Denver sign checklist

Before you design or order anything, confirm:

What's my zoning district? (It sets my sign-area allowance.)
Which permits do I need — zoning, building, electrical, and is my sign lit?
Am I in a historic district? → Landmark Certificate of Appropriateness + material restrictions (no vinyl/plastic/internal-cabinet signs).
Am I planning a roof sign above the roofline, or an animated sign? → prohibited (animated except in specific areas).
Am I in the Theatre District or a BID? → route through their coordinator.

Official Denver resources

Go straight to the city for permits and the binding code:

Denver Development Services — Signs — permit requirements, zoning map, and the Denver Sign Code.

I'm a new business owner and English isn't my first language — where do I start?

First find your zoning district on Denver's zoning map — it sets your allowance. Then figure out which permits your sign needs (zoning + building, plus electrical if lit). Because the order matters and historic districts add Landmark review, most owners hire a licensed sign company that confirms the rules and manages every permit in the stack.

Why can't this page just tell me my exact square footage?

Denver's allowance is buried in zone-specific code the city itself calls tricky, and your real hurdle is the permit stack plus historic overlays — variables that need site-specific confirmation. Anyone who gives you a single number sight-unseen is guessing. We give you the structure and the official sources so you don't get blindsided.

This is an informational guide based on public City and County of Denver sign permit guidance and the Denver Zoning Code / Sign Code, not a permit, legal advice, or a guarantee of compliance. Sign allowances and permit requirements in Denver depend on zoning, historic-district status, and highway proximity that require professional confirmation. Always verify with Denver Development Services and a licensed Denver sign contractor before designing, ordering, or installing a sign.
