Charlotte · UDO Article 22 (Signs)
Why your Charlotte wall sign depends on your zone
Charlotte rewrote its sign rules into the Unified Development Ordinance, where your wall sign is tied to your zoning district and your leasable wall length — and projecting, crown, and skyline signs each have their own separate caps. A single frontage number won't tell you what's allowed. Here's the real structure.
Charlotte's UDO splits signs into types, each with its own rule.
Under UDO Article 22, "wall-mounted signs" (wall, projecting, awning, and canopy signs) are permitted for nonresidential uses in any zoning district — but the maximum area is set by your zone, and in a multi-tenant building it's allocated by tenant according to leasable building wall length along each frontage. Marquee, skyline, roof, and painted wall signs are regulated separately and don't count toward that wall-mounted total. So your real allowance is a stack of type-specific rules, not one formula.
The type-specific caps that are confirmed
These are confirmed in UDO Article 22. Use them as a sanity check before you talk to a fabricator:
Projecting sign
Max 75 sq ft, counts toward your wall-mounted total; one per tenant with street frontage (one per frontage on a corner lot); projects up to 4 ft from the facade.
Crown sign
Only on buildings at least 200 ft tall — up to 4.70 sq ft per building side per foot of height over 200 ft, capped at 750 sq ft, one per side.
Skyline sign
May project up to 24 inches above the roofline/parapet, wall-mounted design; can't coexist with a roof sign.
Ground / pole sign
Monument-type generally; pole signs (ML, CG, CR zones) up to 30 ft tall, 84 sq ft, one per lot.

The rules that catch people off guard
- Wall-sign maximum area is zone-specific, and in multi-tenant buildings it's divided by your leasable wall length — you can't read it off a generic per-foot rule.
- Electronic / changeable-copy components are limited to wall, projecting, ground, or marquee signs, and to 50% of the sign area — except inside the I-277 loop, where 100% is allowed.
- Window signs are capped at 25% of each window (65% for vacant ground-floor spaces).
- Commercial flags max 12 sq ft; banners max 32 sq ft (more allowed in the UC district, up to 1,000 sq ft or 10% of the wall).
- A sign permit is required for installing, enlarging, moving, or replacing most signs; the Planning Department reviews within 15 business days.

⚠ Historic districts add a layer
Signs in Charlotte's local historic districts require Historic District Commission (HDC) design-guideline review before a permit is issued, and landmark/historic signs have their own designation process through the Charlotte-Mecklenburg Historic Landmark Commission. If you're in one of these areas, the base UDO allowance isn't the final word — and review takes longer.

Charlotte sign checklist
Before you design or order anything, confirm:
- What's my zoning district, and my leasable wall length if I'm in a multi-tenant building?
- Is it a projecting sign (max 75 sq ft, counts toward wall total) or a separate skyline/crown/marquee sign?
- Does my sign have an electronic or changeable-copy component? → 50% cap (100% only inside I-277).
- Is my window sign over 25% of the glass? → not allowed (65% if vacant ground floor).
- Am I in a local historic district? → HDC review required before permit.
Official Charlotte resources
Go straight to the city for permits and the binding code:
Charlotte Unified Development Ordinance (UDO) — Article 22 (Signs), zoning districts, and sign permits.
I'm a new business owner and English isn't my first language — where do I start?
First confirm your zoning district and, in a shared building, your leasable wall length — both feed your wall-sign allowance. Then check the type-specific caps (projecting 75 sq ft, electronic 50%, window 25%). Because the UDO is zone-and-type specific and HDC review applies in historic areas, most owners hire a licensed sign company that confirms the rules and pulls the permit.
Why can't this page just tell me my exact square footage?
Charlotte's wall-sign allowance is set by your specific zone and, in multi-tenant buildings, your leasable wall length — then layered with type-specific caps and HDC overlays. Those need your zone and building to confirm. 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 the public City of Charlotte Unified Development Ordinance, Article 22 (Signs), not a permit, legal advice, or a guarantee of compliance. Sign allowances in Charlotte depend on zoning district, leasable wall length, sign type, and historic-district overlays that require professional confirmation. Always verify with the City of Charlotte Planning Department and a licensed sign contractor before designing, ordering, or installing a sign.
