Denton County, TX Sign Regulations: Garage Sale Signs (2026)

Garage sale and yard sale sign regulations in Denton County vary by city. The City of Denton allows temporary garage sale signs on private property without a permit but limits the number and size of signs. Signs may not exceed 6 square feet and are typically limited to 2 or 3 per sale. Signs cannot be placed on utility poles, traffic signs, street signs, trees on public property, or in street medians. Signs placed in the public right-of-way must not obstruct pedestrian or vehicular visibility and must be removed within 24 hours of the sale ending. Lewisville has similar rules and limits garage sales to a specific number per year (typically 3 or 4 per household annually). Flower Mound requires garage sale signs to include the date of the sale and limits placement to private property with the owner's permission. Most cities within Denton County prohibit garage sale signs from being attached to mailboxes, as this violates federal postal regulations. HOAs in Denton County subdivisions may impose additional restrictions on garage sale signage, including prohibiting signs on common area fences and entry monuments. Some HOAs organize community-wide garage sale events and restrict individual sales outside those dates. In unincorporated Denton County, there are fewer restrictions on temporary signage, but signs still cannot be placed on county road signs or in locations that create traffic hazards.
