Sign permits in Houston, TX: rules, fees, and how to apply

Almost every sign in Houston needs a written permit from the Sign Administrator before you erect, alter, relocate, or even use it — the exceptions are narrow (small window signs, construction-site signs under 40 sq ft, and the like). Permits are issued only to licensed sign contractors, or to a business owner personally installing a small non-electrical sign.

“No person shall erect, reconstruct, alter, relocate or use a sign within the sign code application area without first having secured a written permit from the Sign Administrator to do so, subject to the exceptions set forth in Section 4605(b).”

Painted window and door signs are permit-exempt — but an electrical sign, or any sign with a structure bigger than 6 sq ft, sitting in a window visible from the street is treated as a wall sign and needs a permit. And no more than 20% of a glass storefront may carry advertising.

“Signs painted on glass surfaces or windows or doors; provided however, that electrical signs or signs with structures, greater than six square feet in size, that appear in a window in a manner to be visible from the right-of-way shall require a permit as a wall sign. In addition, no more than twenty percent of a glass storefront may be covered with advertising content.”

Each business gets at most 5 on-premise signs total: no more than 1 ground or projecting sign per frontage (2 max overall), no more than 4 wall signs, no more than 3 marquee signs — and roof signs are prohibited for new permits. Count every sign already on the address before designing.

“Each business shall place no more than one on-premise ground sign or projecting sign per frontage.”

Ground-sign height and size caps in Houston come off Table 4611 and depend on the street the sign is visible from. For a single business: scenic/historic streets (Category A) 14 ft and 100 sq ft; major thoroughfares and collectors (Category B) 20 ft and 150 sq ft; freeways (Category C) 42.5 ft and 225 sq ft; local streets (Category D) 8 ft and 60 sq ft. Multi-tenant signs get more (up to 24–31 ft / 300–600 sq ft depending on tenants and street). The city's inspector determines the street category at the site inspection — check your street on the Major Thoroughfare & Freeway Plan and have a human confirm the category before quoting.

“All references in this Code to the size and height limitations contained in Table 4609 of this Code shall be interpreted to refer to the new size and height limitations contained in Table 4611.”

The sign and its structure must sit wholly on the private property — nothing over the public right-of-way (projecting signs may extend up to 10 ft out but no closer than 2 ft behind the curb line). The city's site inspection also checks the 45-foot visibility triangle at corners, a 250-ft sight line for oncoming traffic, 3 ft of clearance from any fire hydrant, and clearance from overhead power lines — that's a field call we can't make from a form, so a human confirms placement.

“With the exception of on-premise signs lawfully permitted or erected prior to the effective date, all on-premise signs and sign structures shall be contained wholly within the premises upon which they are located and shall not extend onto the public right-of-way, provided that on-premise projecting signs may extend up to 10 feet outward from the building to which they are attached, as long as such extension is no closer than 2 feet behind the curb line.”

A second ground or projecting sign on the same frontage is only allowed when the frontage runs more than 350 feet — and the two signs must sit at least 350 feet apart, measured parallel to the frontage.

“However, if a business has more than 350 feet of frontage, two on-premise ground signs, projecting signs, or a combination of these signs that totals two, will be allowed along the frontage; provided, however, that the two signs shall be spaced a minimum of 350 feet apart as measured parallel to the frontage.”

Digital and changeable-message signs are allowed in Houston, with hard limits: the message can change no more often than every 5 minutes (the change itself in 1 second or less), brightness maxes at 6,500 nits by day and 1,250 nits at night with an automatic light-sensing dimmer, no flashing/moving/strobe effects, only one per business, none on local streets (schools excepted), and the changeable portion is limited to 50% of the allowable face, up to 100 sq ft. The city also wants its Acknowledgement Receipt signed by the owner or manager.

“A changeable message sign may not change the message more often than every five minutes and must change the message within one second or less; a high technology sign may not change the message without a new permit.”

The base code makes any new sign over 8 ft above ground or over 60 sq ft carry Texas PE-certified design drawings (plus a certified as-built after inspection). The city's checklist then splits it by installer: an owner-installed wall sign needs engineering over 8 ft or 60 sq ft, while a licensed sign contractor's wall sign needs it over 42'6" tall or when it's flexible substrate over 200 sq ft — and all projecting and marquee signs need engineering. Which regime applies depends on who installs and how it's built, so we flag it for a human call.

“Construction permit applications for any new signs, when erected or constructed to heights exceeding eight feet above ground level or in excess of sixty square feet in size, shall be accompanied by a design drawing of the sign structure and the sign, followed by an as-built drawing based on an on-the-ground inspection, both of which have been prepared by and certified by a professional engineer registered in the State of Texas.”

Ground signs: the base code trigger is over 8 ft or over 60 sq ft (Texas PE certification, design drawing plus as-built). For licensed sign contractors, the city's checklist narrows it to ground signs over 19 ft, or ones built off-center, with transitions in the uprights, with channel letters, or with rebar/anchor bolts — plus any modification of an existing structure. Engineered ground signs also get a footing/hole inspection. The applicable trigger depends on installer and construction, so we flag it for a human call.

“Signs installed by a license City of Houston Sign Contractor must provide engineered drawings for ground signs over 19' and wall signs over 42'6.”

For new wall signs, all wall signs together are capped at 25% of the wall they're mounted on, or 1,000 sq ft, whichever is smaller. (New wall signs also can't rise more than 10 ft above the roof line, and downtown they top out at 42.5 ft.) We need the wall's square footage to run this math — it comes off the building elevation.

“The area of wall signs shall not exceed in the aggregate 25 percent of the area of the wall on which they are mounted or painted, or 1000 square feet, whichever is smaller.”

The plan checker verifies the business's Certificate of Occupancy during review — make sure the occupant's CO is on record and verifiable for this address before you submit.

Houston has ~20 designated scenic and historical rights-of-way and districts (Allen Parkway, Memorial Drive, Heights Boulevard, the Downtown Scenic District, Tanglewood/Post Oak, and more). Signs there follow the strictest Table 4611 column — 14 ft and 100 sq ft for a single-business ground sign — plus tight lighting limits. Check the city's scenic right-of-way maps before designing.

“All on-premise signs on residential rights-of-way and scenic and historical rights-of-way and districts shall conform in all respects to the requirements set forth in Section 4611(b) for general rights-of-way and shall be subject to the following additional restrictions:”

In the Airport Corridor District, new ground signs on major thoroughfares drop to the strict Category A caps (14 ft / 100 sq ft single-business) and freeway signs use Category E (31 ft / 150 sq ft) — noticeably tighter than the citywide freeway allowance.

“All new on-premise signs located in the Airport Corridor District for which a sign permit is issued after July 29, 2020, shall conform to all requirements relating to on-premise signs in the Code, with the exception that ground signs located on major thoroughfares shall comply with the height and size provisions of Category A of Table 4611 and ground signs located on freeways shall comply with the height and size provisions of Category E of Table 4611.”
