Summary
The Zoning Ordinance has no garage-sale-sign-specific rule. Small temporary/portable signs are treated as portable signs (a temporary sign permit, 14-day validity, 32 sq ft max) and may not be placed in the public road right-of-way.
Portable signs and signs for special events and promotions shall require a temporary sign permit issued by the Planning Administrator or a designee... A temporary permit for a portable sign shall be valid for fourteen (14) days... Portable signs shall not exceed thirty-two (32) square feet of area.
Full Breakdown
Unincorporated Polk County does not single out garage-sale signs. Portable signs and signs for special events or promotions require a temporary sign permit from the Planning Administrator; a portable-sign permit is valid for 14 days, and no person may obtain more than four such permits in one year. Portable signs may not exceed 32 sq ft. Signs must observe the ordinance's placement rules, which keep signs off the public road right-of-way. Within incorporated cities (Des Moines, Ankeny, Urbandale, etc.) municipal sign rules apply instead. Small, briefly displayed yard-sale signs on private property are the common practice; commercial/repeated signage triggers the portable-sign permit.
Violations & Fines
Signs placed in the right-of-way or without a required temporary permit may be removed and are enforced by Polk County Planning & Development.
