Full Breakdown
Multnomah County Code treats a yard-sale sign as a temporary sign under MCC 39.6810. As a lawn sign it cannot exceed three square feet in area or 42 inches in height, cannot be permanently attached to the ground, a building, or any other structure, and must be removed within six months of erection. Countywide sign rules at MCC 39.6710 require a sign permit before any sign is erected unless it falls under one of the exemptions listed at MCC 39.6720, and lawn/temporary signs are not on that exemption list. This applies only to unincorporated Multnomah County (mostly east county and rural areas). Portland, Gresham, Troutdale, Fairview and Wood Village enforce their own municipal sign codes, not this one.
Violations & Fines
Oversized or overheight lawn signs, or signs left up past six months, are subject to removal and the County's standard zoning code enforcement process for prohibited/nonconforming signs under MCC Chapter 39.
