Alameda, CA Landscaping Rules: Grass Height Limits (2026)

Unlike many California jurisdictions, the City of Alameda does not codify a specific maximum grass or weed height in its municipal code. The City's general nuisance authority is found in Alameda Municipal Code Section 24-1 (Health Nuisances), which lets the City Manager declare conditions that menace public health a nuisance and order abatement, but it lists conditions such as animal-quarter odors, sewage discharge, and wind-blown dust rather than a numeric grass height. Where overgrown, dry, or dead vegetation creates a fire risk, the City relies on the adopted Alameda Fire Code (Chapter XV, Section 15-1) and state defensible-space law rather than a local height number. By contrast, ALAMEDA COUNTY's code (Section 6.65.030) requires grasses and weeds on unincorporated parcels to be cut to a height not exceeding six inches; that rule does NOT apply inside the incorporated City of Alameda. In practice, Alameda residents who let yards become overgrown are addressed through the City's Code Enforcement division (Planning, Building and Transportation Department), which investigates complaints and issues abatement notices. There is no published mow-height ordinance, so enforcement is condition- and complaint-driven rather than triggered by a fixed measurement.
