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

Fullerton's property maintenance standards require all property owners and occupants to maintain landscaping and vegetation in a manner consistent with community standards and public safety. The Municipal Code's nuisance and property maintenance provisions (Chapter 15.48) establish that overgrown vegetation — including unmowed grass, weeds, and uncontrolled plant growth — constitutes a public nuisance when it reaches heights that create fire hazards, harbor rodents or insects, or detract from the visual character of the neighborhood. While the code does not specify an exact maximum grass height in inches, the practical enforcement threshold is approximately 12 inches, consistent with Orange County fire prevention standards. The Fullerton Fire Department and Code Enforcement Division coordinate on properties where overgrown vegetation creates fire risk, particularly during California's dry season (May through November). All lots — whether occupied, vacant, or under development — must be maintained free of dead vegetation, accumulated plant debris, and conditions that attract vermin. Property owners are responsible for maintaining the parkway strip between the sidewalk and curb in front of their property. Fullerton's historic tree-lined streets mean parkway maintenance includes care of street trees, though the city's Public Works Department manages significant tree trimming on city-owned parkway trees.
