Texas Flagpole Rules: HOA Law, Permits, Wind and Digging

Can a Texas HOA Stop You Putting Up a Flagpole?

No, not entirely. Texas Property Code section 202.012 says a property owners' association may not ban the U.S. flag, the Texas flag, or an official or replica flag of any branch of the U.S. armed forces^[1]. It may regulate flagpoles, but it may not prevent one pole per property that is either no more than 20 feet tall and in the front yard, or attached to the owner's house^[1].

The HOA keeps a real say. It can require permanent materials with a finish that suits the house, set the flag size, regulate flag lights, limit noise from an external halyard, require the pole to meet zoning, easements and setbacks of record, and keep poles off common land^[1].

It protects owners, not renters, and does not list the POW/MIA flag^[1]. A taller or second pole is up to your HOA.

When Does Texas811 Need to Hear Before a Flagpole Hole Is Dug?

Texas Utilities Code section 251.151 requires notice to a notification center no later than the 48th hour before digging, not counting Saturdays, Sundays and legal holidays, and no earlier than the 14th day before^[2]. The center is Texas811, and line owners mark at no charge^[12]. CenterPoint Energy asks for three working days^[13], and Oncor says to call before digging 16 inches or deeper^[12].

A flagpole hole runs about a tenth of the pole's height, roughly 2 feet for a 20 foot pole, so we file the 811 request before every dig. Private lines such as sprinkler pipes, invisible pet fences and yard lights are the owner's to mark^[13], so tell us where yours run.

How Far Must a Flagpole Stay From Power Lines in Texas?

Texas Health and Safety Code section 752.004 bars work where a person, tool, machine or material could come within six feet of a high-voltage overhead line, unless the line has first been guarded^[3]. High voltage means more than 600 volts^[14].

Six feet is the legal floor, not a safe distance for a pole. CenterPoint Energy tells people to keep their body, tools, materials and equipment at least 10 feet from overhead lines at all times^[15]. A pole is long, conducts electricity and can tip while it is raised, so we place it where the whole pole stays clear of any line.

Can You Fly the Texas Flag at the Same Height as the U.S. Flag?

Yes, on separate poles. Texas Government Code section 3100.055 says that when the two flags fly on separate poles at the same place, the poles should be the same height, the flags should be about the same size, and the U.S. flag should be on the observer's left^[16]. On one pole, the U.S. flag should fly above the Texas flag^[16].

The section is worded as guidance, with "should". Note that section 202.012 guarantees one pole, not two^[1]. A flag left up after dark may fly 24 hours a day when properly lit, under the U.S. Flag Code^[17].

Who Sets Flagpole Permit and Height Rules in Texas?

Cities do. The model building code's permit-exempt list does not name flagpoles^[18], so each Texas city writes its own line. Houston and Dallas use the same permit line. Lubbock does not.

A permit exemption is not a height allowance. Dallas decides how its height caps apply to a pole. Houston's residential code does not list flagpoles as exempt work^[10], so the Houston Permitting Center, (832) 394-8820, has the final word for a house^[26]. Prosper, by contrast, needs no permit but caps a residential pole at 30 feet^[27].

What Wind Speed Should a Texas Flagpole Be Rated For?

Building plans list an ultimate wind speed. Flagpole ratings use an older, lower scale, and multiplying by 0.775 converts one to the other^[9]. On that scale most of the country sits near 90 mph, rising toward the Gulf coast^[9].

Houston prints no single figure. Its code says to look up each address in the ASCE 7 hazard tool at Risk Category II^[10]. Hurricane Beryl in July 2024 brought an unofficial gust of 84 mph at Hobby Airport^[28], and on the High Plains Lubbock Airport recorded 82 mph on March 14, 2025^[29].

A flag cuts a pole's rating. One 25 foot pole with a 5 inch base and 0.156 inch wall is rated 183 mph bare and 120 mph with a 4 by 6 foot flag^[30], while light-duty 15 and 20 foot telescoping poles are rated for 75 mph with 3 by 5 foot flags^[31].

How Do Texas Soils and Frost Depth Change a Flagpole Footing?

Houston's and Dallas's design tables list a frost line of 6 inches^[10][7] and Lubbock's 12 inches^[11], all above a typical pole footing, so the usual depth of a tenth of the pole's height holds.

Dallas County is heavy Blackland Prairie over Austin chalk^[32]. Blackland soils are cracking clays whose shrink and swell can damage foundations^[33], and the Houston Black series there is 40 to 60 percent clay with dry-season cracks up to 4 inches wide^[34]. The south half of Harris County is heavy black coastal clay^[35], and the Lake Charles soil common there drains very slowly and cracks half an inch to 2 inches wide^[36].

The building code gives clay half the sideways bearing value of gravel, 100 against 200 pounds per square foot per foot of depth^[37], so a pole in clay can need a wider or deeper footing. In the Hill Country, shallow soil over limestone often means cutting into rock^[38]. Around Lubbock a caliche hardpan lies two to three feet down^[39], and in the Acuff soil the chalky layer runs from 30 to 60 inches^[40], so a home pole's hole often ends in it. We size each footing to the site and the pole maker's specs.

What Should You Do First Before a Flagpole Goes In?

• Read your HOA rules and deed restrictions, and get approval where they require it^[1].
• Check your city's rule on its page, such as Houston or Dallas, or find your town on our areas page.
• Note overhead lines, trees, and anything buried near the spot.

Then send us the address, the height you want and a photo of the spot. See how it works, typical costs and common questions.
