Houston · Sign Code Chapter 46
Why your Houston sign can't be sized by a simple formula
Most US cities tie your sign to your zoning district. Houston doesn't have zoning — so your allowance depends on which street category your storefront faces. Here's what actually controls your sign, and where the hard limits are.
Houston is the only major US city with no zoning.
That's not a quirk — it changes everything about your sign. There's no "C-2 district" or "commercial zone" to look up. Instead, the Houston Sign Code (Building Code Chapter 46) sets your sign's allowed height and size by the category of the street your sign faces. Two shops on the same block can have very different limits if one faces a freeway and the other faces a local street.
Your street category decides everything
Before anything else, you need to know which category your premises frontage falls into. This single fact drives your height and size caps:
Category A
Local streets, predominantly residential rights-of-way, and scenic/historic rights-of-way and districts. The most restrictive.
Category B
Major thoroughfares other than residential/scenic-historic rights-of-way.
Category C
Freeways other than residential/scenic-historic rights-of-way. The most permissive for height.

The structural limits that apply citywide
Regardless of street category, these caps are confirmed in the Houston Sign Code. Use them as a sanity check before you ever talk to a fabricator:
- Maximum 5 signs total per business — usually a combination of ground, projecting, wall, and marquee signs.
- No more than 4 wall signs.
- No more than 3 marquee signs.
- One ground or projecting sign per street frontage (two if your frontage exceeds 350 feet and the signs are at least 350 feet apart), for a maximum of two ground/projecting signs total.
- Roof signs are prohibited. Signs also can't extend above the roofline or be mounted on canopies or awnings.
- Wall signs may not exceed 50% of the total surface of the wall they're mounted on.

⚠ The engineering trigger most owners miss
A ground sign over 60 sq ft or taller than 8 feet, or a wall sign mounted higher than 16 feet above grade, requires sealed engineered drawings and structural analysis under the Houston Construction Code. This isn't optional — and it's why most Houston businesses can't legally DIY their sign.
Who can actually pull the permit?
This is the part that trips up new and first-time business owners. Under the Houston Sign Code, permits are only issued to whoever is doing the work — either a licensed sign contractor, or the business owner only if they perform all the work themselves (and only for minor, non-electrical signs under the size/height triggers above).
In practice, that means: if your sign is illuminated, oversized, or mounted high, you must hire a licensed Houston sign contractor. A business owner cannot pull the permit and then hand the job to someone else.

Houston sign checklist
Before you design or order anything, confirm:
- Which street category (A/B/C) does my frontage face?
- How many signs do I already have? (Hard cap is 5 total, 4 wall.)
- Is my wall sign under 50% of the wall surface?
- Is any ground sign over 60 sq ft or 8 ft tall, or a wall sign over 16 ft high? → sealed engineered drawings required.
- Is the sign illuminated or near a county toll road? → extra permits / licensed contractor required.
- Am I planning a roof sign? → prohibited, don't bother.

I'm a new business owner and English isn't my first language — where do I start?
Start by identifying your street category, then count any existing signs against the 5-total / 4-wall cap. Because Houston only issues permits to the party doing the work, most owners hire a licensed sign company that confirms the limits and pulls the permit as part of the job.
Why can't this page just tell me my exact square footage?
Houston's allowance depends on your street category, sign type, building height, and proximity to freeways and residential rights-of-way — variables that need on-site confirmation. Anyone who gives you a single number sight-unseen is guessing. We give you the structural limits and the official sources so you don't get blindsided.
This is an informational guide based on the public Houston Sign Code (Building Code Chapter 46), not a permit, legal advice, or a guarantee of compliance. Sign allowances in Houston depend on street category, building dimensions, and site conditions that require professional confirmation. Always verify with the City of Houston Sign Administration and a licensed Houston sign contractor before designing, ordering, or installing a sign.
