Alameda, CA Property Maintenance: Vacant Lot Maintenance (2026)

The City of Alameda's development regulations (Alameda Municipal Code Chapter XXX) require that a person, company, or corporation utilizing a lot maintain that lot in good order at all times, and provide that where a public street, alley, or parcel of land is officially vacated or abandoned, the regulations applicable to abutting property apply equally to the vacated street, alley, or parcel. Vacant and unimproved lots also remain subject to the City's general property-maintenance and littering provisions in Chapter IV, Article I, which require street-visible property to be kept free of waste matter, and to Chapter XV (Fire Prevention), which the City adopts to control fire hazards such as combustible vegetation and rubbish. Unlike unincorporated Alameda County—where County Code Chapter 6.65 imposes a specific six-inch maximum weed height and fifteen-foot defensible-space clearance on real property—the City of Alameda regulates overgrowth and debris on vacant parcels through its own nuisance, maintenance, and fire-prevention chapters rather than that County standard. Owners of vacant lots should keep them free of accumulated debris, illegal dumping, and fire-prone vegetation, and may be cited under the applicable City chapter if a parcel becomes a nuisance.
