Houston FAQ
Can existing billboards convert to digital?
No. Houston denies digital conversion waivers for legal nonconforming off-premise billboards. The 1980 sign code policy reflects voter and council preference against new outdoor digital advertising citywide.
Are digital signs allowed at gas stations?
Yes for on-premise pricing and goods displays, subject to brightness, dwell-time, animation, and setback rules. Off-premise advertising on the same sign would violate Chapter 46.
Pasadena FAQ
Can I put up a digital billboard in unincorporated Harris County?
Only by securing a TxDOT outdoor advertising permit under Transportation Code Chapter 391, meeting the 8-second hold and night luminance rules, and on a properly zoned commercial parcel. New permits along controlled highways are difficult and tightly limited.
Why do Houston freeways have so few digital billboards?
Houston's sign code largely bans new off-premises and digital billboards inside city limits, only allowing conversion of pre-existing conforming faces under tightly capped agreements. Conversions still require TxDOT permits and meet state hold and luminance standards.
