Riverside's Invasive Plant Rules: The Rules That Matter

Every city handles invasive plant rules a little differently. In Riverside, California, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Front Yard Gardens

California Civil Code Section 4735 forbids HOAs from banning drought-tolerant or native-plant front yards and Government Code Section 53087.7 protects personal vegetable gardens. Riverside's landscape standards in RMC Title 19 allow drought-tolerant and edible front-yard landscapes as long as they're maintained and meet setback/visibility standards.

The rules around front yard gardens in Riverside lean permissive, but that does not mean anything goes.

Bamboo Restrictions

Riverside does not ban bamboo but treats uncontained running bamboo that spreads onto neighboring property as a private nuisance. Clumping varieties are generally fine; running bamboo (Phyllostachys) typically requires rhizome barriers. Encroachment is a civil matter under California Civil Code Section 3479.

Prohibited Species

The California Department of Food and Agriculture maintains the statewide Noxious Weed list (Food & Ag Code §7270+) that applies in Riverside. Arundo donax (giant reed), tamarisk (salt cedar), and pampas grass are specifically targeted for removal in the Santa Ana River corridor through regional invasive-species programs.

The Bottom Line

Compared to many U.S. cities, Riverside gives residents more room on invasive plant rules. 2 of the 3 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
