McKinney Digital Sign Ordinance Rules

Signs and Advertising Texas 3 Minutes Read · published February 21, 2026 Flag of Texas

In McKinney, Texas, digital signs (including LED and electronic message boards) are regulated to balance safety, neighborhood character, and commercial expression. This guide summarizes the city rules on brightness limits, message rotation and dwell times, permitting, and enforcement so businesses and property owners can plan compliant displays and respond to notices. Where the municipal code or permitting pages do not state specific figures, this guide notes that the amount is "not specified on the cited page" and points to the official source for current text and forms.

What the rules cover

McKinney regulates sign size, location, illumination, and changeable message features. Key topics for digital displays include maximum luminance, required dimming or automatic adjustments for night, allowed message transition methods (instant vs. fade), minimum dwell time per message, and restrictions near residential zones and traffic corridors.

Permits and approvals

Most permanent digital signs require a sign permit and review by Development Services or Planning. Free-standing electronic message centers and building-mounted digital displays typically need site plan approval or a permit amendment. Check the city's sign permit page for application forms, submittal checklists, and fee schedules Sign Permit & Requirements[1]. The consolidated municipal code contains the controlling ordinance language and definitions for "electronic message display" and related terms McKinney Code of Ordinances - Signs[2].

Penalties & Enforcement

Enforcement is handled by Code Compliance/Development Services and Building Inspection; violations commonly arise from unpermitted installations, noncompliant illumination levels, or prohibited message change methods. Specific monetary fines and schedules are not always listed verbatim on the cited pages; where amounts are absent the text below notes "not specified on the cited page" and directs you to the official source for the exact penalty provisions.
