Washington County, OR Property Maintenance: Garage Sale Rules (2026)

Property maintenance obligations apply during and after garage sales throughout Washington County. Under Beaverton BC 9.05, Hillsboro HMC 8.20, Tigard TMC 7.40, and Tualatin TMC 8-5 general nuisance provisions, merchandise, tables, racks, and display items must be stored out of public view each evening during a sale and fully removed within 24 hours of the last sale day. Unsold items left at the curb become accumulated junk under property maintenance codes and can trigger immediate blight citations. Signs announcing the sale must be removed within 24-48 hours per local sign codes; signs left longer are often removed by code enforcement at the property owner's cost. Unincorporated Washington County relies on CDC §430 property maintenance and general nuisance provisions enforced by the Sheriff's Office and county code enforcement. Habitual patterns of visible clutter (ongoing garage-sale-like displays) can escalate to ongoing nuisance abatement. HOAs in Bethany, Oak Hills, Murrayhill, Sherwood's Brookman, and other subdivisions often have stricter rules — some prohibit merchandise from being visible in front yards even during a legitimate sale.
