Hawthorne, CA Property Maintenance: Weeds & Overgrown Grass (2026)

Vegetation maintenance in Hawthorne is governed by the city's own nuisance code (Chapter 8.20 of the Hawthorne Municipal Code), not Los Angeles County rules. Property must be kept substantially clean and free from accumulations, including overgrown, dead, or decayed trees, weeds, or other vegetation, rank growth, garbage, litter, debris, and flyers. The code declares dead, decayed, diseased, or hazardous trees, weeds, ground cover, and other vegetation, or the absence of healthful vegetation, a nuisance when they cause, contribute to, or promote conditions such as fire hazards, creation or promotion of dust or soil erosion, diminution in property values, or detriment to public health, safety, or welfare. Owners are required to maintain landscaping and plant materials in good condition as part of the city's active-maintenance standard. While the code uses qualitative standards rather than a published inch-by-inch grass-height limit, overgrown weeds and rank growth that meet the nuisance criteria can be ordered abated. If the owner fails to act, the city may abate the vegetation nuisance at the owner's expense and record the cost as a lien against the property. No fetched city source specifies a numeric weed or grass height threshold, so none is asserted here; enforcement is based on the nuisance conditions described in the code.
