Warren, MI Sign Regulations: Garage Sale Signs (2026)

13(h) exempts garage sale signs from the city's general sign permit process, but only within narrow limits. A homeowner may post exactly one garage sale sign, sized four square feet or less, and it must sit in the front yard setback at the site of the garage sale itself, not at a separate off-site location. 42, which caps sales at four consecutive days and no more than two per parcel each calendar year. Because the sign exemption is tied to that license, a sign posted before the licensed dates begin or left up after the sale concludes falls outside the exemption.

The exemption sits within Division III's broader list of signs not requiring a permit, a category that also includes real estate signs, opinion signs, and construction signs, each with its own separate size cap, so a resident cannot combine allowances or treat the garage sale sign limit as a floor for additional temporary signage. General sign standards elsewhere in Article IV-A still apply to anything not specifically excused, including the rule that no sign may obstruct a driver's view of traffic at an intersection or be erected on public right-of-way, a utility pole, or a tree.
