Portland regulates vacant lots under Title 29 (Property Maintenance Regulations). Vacant lot owners must maintain their property free from nuisance conditions including overgrown vegetation, accumulated debris, and hazardous conditions. The Neighborhood Inspections team enforces vacant lot maintenance standards.
Vacant lot owners must keep vegetation mowed or maintained to prevent fire hazards and rodent harborage. Debris, junk, and abandoned vehicles must be removed. Fencing or barriers may be required for lots with hazardous conditions like open excavations. The city tracks vacant and derelict properties through the Derelict Buildings Program. Portland's community development initiatives encourage productive use of vacant lots through community gardens and interim uses.
Non-compliant vacant lots receive notices with compliance deadlines. Fines under Title 29 apply for continued violations. The city may mow overgrown lots and assess costs as a lien against the property. Repeat offenders face escalating penalties.
