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.
30-second risk check
No address, no measurements — just tap Yes or No. This flags where a Houston sign goes wrong.
Do you know which street category (A/B/C) your premises frontage faces? It sets your height and size caps.
Do you already have signs that would push you over the 5-total / 4-wall hard cap?
Will a wall sign cover more than 50% of the wall surface it's mounted on?
Is any ground sign over 60 sq ft or 8 ft tall, or a wall sign mounted higher than 16 ft above grade?
Are you planning a roof sign, or a sign that extends above the roofline / on a canopy or awning?
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.

How to apply for a Houston sign permit
Houston's order is unusual: the street in front of you decides your limits, and who does the work decides who files.
1. Confirm you're inside the city limits
This procedure is the City of Houston's. A site in unincorporated Harris County — outside the city limits — falls under the county instead, with its own authority and its own rules, so none of the steps below apply. Settle which one you're in before anything else.
2. Identify your street category
Category A (local, residential, scenic/historic rights-of-way), B (major thoroughfares), or C (freeways). This single fact drives your height and size caps.
3. Count your existing signs against the cap
Count any signs already up against the 5-total / 4-wall cap before adding another.
4. Flag illumination or a county toll road
An illuminated sign, or one near a county toll road, means extra permits and a licensed contractor.
5. Check whether you are even allowed to file
Sign Administration issues permits only to licensed sign contractors — the filer is decided by who you hire, not by who owns the business. The City names the exceptions where the permit goes to the individual instead, and they are narrow: a non-electrical ground sign no taller than 8 feet within the City's stated size limit, or a non-electrical marquee or wall sign mounted no higher than 16 feet above grade, in both cases only if the sign meets every other part of the sign code and all of the work is performed by the business owner. Anything electrical is out.
6. Apply online, then clear the site inspection
The application process must be completed online. Before the build inspections there is a separate site inspection, and the City lists exactly what it checks: the street category (local, major thoroughfare, freeway, scenic or historic district, or predominantly residential right-of-way), whether the location exceeds the number or classification of signs allowed, that the sign is not in the 45-foot visibility triangle and does not obstruct oncoming traffic for at least 250 feet, that the location is wholly on private property, that at least 3 feet is kept from any fire hydrant, that underground utilities are marked, and that clearance is kept from overhead power and communication lines. Mark or stake the location on site, or show it on a dimensioned site plan — and a survey is required for a new ground sign.
7. Know which inspections your sign triggers
A construction (hole) inspection is required for drilled footings larger than 18 inches in diameter or 6 feet deep, where rebar or anchor bolts are used (which also means engineering in the application packet), or for any new engineered ground sign. For an electrical sign there are two more: a shop inspection before installation, and a final electrical inspection once it is energized — the Sign Inspector's final only happens after Electrical signs off. Upon final approval the operating permit is affixed to the sign structure or the nearest window.
8. Book inspections by 4 pm the day before
Every inspection except the site inspection must be scheduled by 4 pm the day prior. Missing that cut-off costs you a day, not an hour.
9. Budget it as an annual cost, not an install cost
This is the structural point most owners get wrong. An on-premise sign permit in Houston is an annual operating permit that has to be renewed every year — not a one-time fee you pay when the sign goes up. The charge is built as a base covering the first 32 sq ft, plus an increment for the area above that, so a larger sign costs more every year it stays up, not just once.
10. If it is a billboard, start from "no"
Off-premise signs are a closed class in Houston. The City states that no new permits can be issued for off-premise signs, with a single exception under §4612(b) of the Houston Sign Code. Relocation permits are issued for certain off-premise signs and run for a single three-year period when every applicable provision is met. If your project is a billboard rather than an on-premise business sign, the question is not how to size it — it is whether it can exist at all.
Steps assembled from Houston Permitting Center — Sign Administration (Houston Public Works, Building Code Enforcement) and from the confirmed items on this page; the Houston Sign Code was adopted in May 1980 and revised in July 2020. Fees and timing are handled in their own sections below — not repeated here.
Fees
We publish no amount here, because a stale fee is worse than none — and Houston's move annually. What matters more than the number is when the money is due and how often. Houston's on-premise sign permit is an annual operating permit renewed every year, not a one-time install charge, and the charge is built as a base covering the first 32 sq ft plus an increment for the area above it — so a larger sign costs more every year it stays up. The City says most fees are based on size and are calculated during plan review, and that the balance of the construction, electrical and operating fees is charged when the site inspection and the permit application are approved — so the amount you pay to open the file is not the amount the permit costs. Confirm the current figures in the City's "Building Code Enforcement Sign Administration Fee Schedule" through the Houston Permitting Center, which also publishes a fee calculator. Note that those fees are subject to an automatic increase each January 1, so a quote obtained late in the year will not match what you pay after the turn.
How long it takes
Houston publishes no turnaround for a sign permit — no service standard, no target, no range. Rather than fill that gap with a number we cannot source, here is what the City does fix about timing, and what it leaves open:
The one deadline the City does set
Every inspection except the site inspection must be scheduled by 4 pm the day prior. This is the only timing rule Sign Administration states outright, and it is yours to hit — miss it and the inspection moves a day. City-published: Houston Permitting Center, Sign Administration
What sits between you and the permit
The path has more gates than most cities: plan review, a site inspection, then the build inspections — and for an electrical sign a shop inspection before installation plus an electrical final that must clear before the Sign Inspector's final. Each gate is a scheduling round, so the count of gates predicts your calendar better than any single figure would. City-published: Houston Permitting Center, Sign Administration
Why we quote no week count
We found no City-published processing time for Houston sign permits, and we do not carry a secondary estimate for this city. An unsourced range would read as a commitment the City never made. Ask Sign Administration directly at 832.394.8890 (1002 Washington Ave., 4th Floor; 8 am to 4:30 pm) for your case. Not obtained — no City service standard published, and no secondary source registered for this page
The scheduling deadline, the inspection sequence, and the contact details are City-published by Houston Permitting Center — Sign Administration. No processing-time figure appears on this page because none was obtained; we do not substitute an estimate.
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.
Official Houston resources
Go straight to the city for permits and the binding code:
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.
