Frisco, TX Sign Regulations: Window Signs (2026)

Chapter 70 of the Frisco Code of Ordinances defines a window as 'the total extents of a portal including mullions and spandrel panels,' and Section 70-17(12) treats a window sign as any sign displayed on the inside of that opening. A property owner or lessee may install one window sign per window with no time restriction and no sign permit, unless the sign is illuminated, in which case a permit is required before it goes up. The sign face itself cannot exceed 25 percent of the window it occupies, and only one sign is allowed per window regardless of size.

Illuminated window signs must remain completely static: the code bars blinking, strobing, fading, flashing or scrolling on both illuminated and nonilluminated window displays and their appendages. This sits alongside Section 70-18, which flatly prohibits an entire category of signage citywide and in the extraterritorial jurisdiction, including audible signs, moving signs, revolving signs and any off-location or off-premises sign, so a window display that tries to move, flash or advertise a business elsewhere fails on two fronts at once. The building official administers the sign chapter and can order removal of a noncompliant sign; Section 70-24 lets the city bill the sign or property owner for removal costs and file a lien if those costs go unpaid within 15 calendar days of billing.

HOA or POA deed restrictions that are stricter than Chapter 70 still control under Section 70-19, so a subdivision's own rules can cut a window sign allowance further than the city's 25 percent baseline.
