Quick answer

Most exterior business signs in Houston need a permit before anything goes up. The Houston Permitting Center’s Sign Administration office issues it under Chapter 46 of the City’s Building Code, the Houston Sign Code. Only a licensed sign contractor can pull the permit, and the City lists its review time as 4 to 11 business days. If your site is outside the city limits, the county may be the one to ask. This page shows how to tell.

Who issues sign permits in Houston

Houston Public Works, Sign Administration, at the Houston Permitting Center, 1002 Washington Ave., 4th Floor, Houston, TX 77002. The phone number is 832.394.8890 and the office is open 8 am to 4:30 pm. The application is made online. Many questions can be settled with a plan analyst by phone or in person before you apply.

The rules for signs sit in Chapter 46 of the City’s Building Code, which the City adopted in 1980 and last revised in July 2020. The height, size and lighting your sign can have depend on the category of the street it faces.

City limits or county? Check this first

Chapter 46 reaches into the area just outside the city, called the extraterritorial jurisdiction. For business signs on the property they advertise, the part of that area inside Harris County is left to the county. So a site with a Houston mailing address can still fall under Harris County.

This matters for much of northwest Houston, Cypress and Spring, where city and county lines run street by street. If you are not sure, ask before you design. In unincorporated Harris County, sign permits come from the Office of the County Engineer, Sign Permitting group, at 713-274-3981. The county asks for a site plan, sign details, a survey for ground signs and proof of occupancy, and signs over 30 feet need structural plans. The county lists plan review at 3 to 5 business days.

Who can apply

Houston issues sign permits to licensed sign contractors. We hold the City of Houston sign contractor license, so we pull the permit ourselves. The City says that if a business owner hires someone to do the work, that person or company must hold the license, and the licensed contractor permits and performs the job. Selling or making signs needs no license. Installing them for other people does.

There is one narrow exception. A business owner can take out a permit for certain small, non-electrical signs when the owner does all the work personally. The permit stays with that person and cannot be handed to a hired crew. Before you hire anyone, ask to see their City of Houston sign contractor license. Ours is available on request.

What the application needs

The City asks for:

the General Prerequisites checklist, completed
the On-Premise Sign Permit application, notarized (the business owner or manager signs an affidavit, and so does the contractor)
a plot plan with a north arrow and the nearest cross street, showing the building and every existing, proposed and removed sign
elevation drawings with dimensions and the overall height
an electrical permit application if the sign is lit, with the electrical load
a survey for any new ground sign, including a cabinet change-out on an existing ground sign
sealed, signed structural drawings for larger or heavier signs, such as wall signs over 8 feet high or 60 square feet, ground signs with off-center uprights, and any projecting or marquee sign
a valid Certificate of Occupancy for the building

A lit sign needs a separate electrical permit. Only a registered master electrician can obtain it. The sign gets a shop inspection before it is installed and an electrical final after it is energized.

The City’s checklist does not list a landlord letter. Your lease may still require your landlord’s approval, and shopping centers often have their own sign criteria, which can be stricter than the City’s. Read them before you pay for design.

How long a permit lasts, and renewal

The operating permit renews every year, and a late renewal adds a penalty. The construction permit is good for 180 days from the site inspection. You can buy one 180-day extension, but only before the permit lapses. If it lapses first, the permits are void and you apply again. Permits cannot be moved from one sign or location to another.

What Chapter 46 limits

The City’s sign code is long. These are the limits that come up most often. The text we read is current through the July 2020 revision.

How many signs: up to five on-premise signs per business. One ground or projecting sign per frontage, up to two in total, unless the business has more than 350 feet on one frontage. No more than four wall signs and three marquee signs.
Wall signs: for signs first permitted after September 1, 2009, the total wall sign area is capped at 25 percent of the wall or 1,000 square feet, whichever is smaller.
Ground signs for a single business: 8 feet tall and 60 square feet on a local street, 20 feet and 150 square feet on a major thoroughfare or collector, and 42.5 feet and 225 square feet on a freeway. Signs shared by several tenants get larger limits.
Electronic message signs: no blinking, flashing or moving effects, and the message cannot change more often than every five minutes. Brightness is capped at 6,500 nits by day and 1,250 nits from sunset to sunrise, with an automatic sensor. One per business, and none on a local street.
Window signs: paint on glass needs no permit. An electrical sign, or a structure over 6 square feet visible through the window, needs a wall sign permit. Advertising can cover no more than 20 percent of a glass storefront.
Temporary banners: a limited use banner permit covers up to 40 square feet, flat against an exterior wall, for no more than seven days in any 30.
Billboards: Houston does not issue new permits for off-premise signs.

Mistakes that cost time

Ordering the sign before the permit. The permit decides the size and height, so it has to come first.
Drawings with no height, no electrical load or no survey. The City sends them back.
Not checking the Certificate of Occupancy on a new tenant space.
Assuming a face change on an existing ground sign needs no paperwork. A cabinet change-out still needs a survey.
Treating the landlord’s sign criteria as the City’s rules, or the reverse.

Where we come in

We prepare the permit package and submit it for you as part of the job. See sign permits and approvals. Call (281) 909-7110 or ask for a quote and tell us the address, so we can say first whether the City or the county issues the permit.

When you invest in a commercial sign, you are not only buying something that looks good; you are investing in the visibility of your business. One of the most common questions business owners ask is, “How long will my sign last?” It is a fair question, especially when signs are exposed to sun, wind, rain, and daily wear.

Commercial signs can last a long time, but only with the right materials and proper maintenance. Here is a clear explanation of how long signs last and how to get the most from yours.

Average Lifespan of Commercial Signs

There is no single lifespan that applies to every sign. How long a sign lasts depends on its type, its materials, and the environment where it is installed.

A well-made commercial sign can last roughly 7 to 15 years, and some last longer with good maintenance. Outdoor signs wear faster than indoor signs, but modern materials and LED lighting have significantly extended sign lifespans.

How Different Sign Types Hold Up Over Time

Channel letter signs are known for durability. The letters are usually made of aluminum and acrylic, which resist rust and fading, and each letter is built individually. With LED lighting, these signs can stay bright for many years.
Cabinet signs are also long-lasting when they are built with strong frames and good lighting. The printed face can be replaced over time, while the rigid structure stays in place.
Digital and LED message signs are different. The sign structure may last for many years, but the electronic components may need to be updated or repaired much sooner, particularly in high-traffic areas.

What Affects the Lifespan of a Commercial Sign?

Several factors determine how long a sign lasts.

Weather. Signs exposed to strong sun, heavy rain, or extreme temperatures do not last as long as signs in sheltered spots. You can check conditions in your area with the National Weather Service.
Quality of installation. A sign that is poorly installed can shift, shake, or develop electrical problems, which shortens its life. This is why professional installation is just as important as the sign itself.
Maintenance. A sign that is checked and cleaned regularly will almost always outlast one that is ignored.

Simple Maintenance Tips That Make Signs Last Longer

Maintenance does not have to be complicated or costly. Even small tasks help keep your sign presentable and in good working order:

Clean the sign surface to remove dirt and dust.
Check the lighting regularly and replace dim or failed LEDs.
Inspect electrical connections for safety.
Look for cracks, fading, or loose parts.
Schedule professional inspections when needed.

These simple steps prevent small issues from turning into major repairs.

When Should You Repair or Replace a Sign?

Not every sign problem calls for a full replacement. If the structure is sound and the design still suits your brand, repairs are often enough. Replacing the lighting, renewing panels, or restoring colors can extend the life of a sign by many years.

If your sign is outdated, hard to read, or no longer reflects your brand, it may be time to upgrade. Current signs are more visible, use less energy, and look more contemporary.

Why LED Signs Last Longer Than Older Signs

LED technology is one of the main reasons modern signs last longer. LEDs use less power, produce less heat, and have much longer lives than conventional lighting. That means fewer failures, lower maintenance costs, and better long-term performance. For many businesses, LED signage has reduced long-term costs while improving visibility.

Commercial signs are built to last, but how long they last depends on quality, environment, and maintenance. With the right materials and regular attention, your sign will serve your business for many years.

Think of your sign as a long-term business partner. When you look after it, it keeps advertising your brand 24 hours a day. A good sign is not only one that lasts longer, but one that keeps making a good first impression.
