Rancho Cucamonga FAQ
How tall can my lawn grow before Rancho Cucamonga cites me?
The general standard is about 6 inches. Foothill VHFHSZ properties should maintain grass to 4 inches during fire season.
What if I am on vacation during a violation notice?
Contact Code Enforcement at (909) 477-2700 immediately to request an extension. Ignoring notices leads to abatement and liens.
Do HOAs enforce stricter standards?

Rialto FAQ
How tall can my front lawn be in Rialto?
There is no single numeric grass-height threshold in the code, but Title 8 and Title 18.61 require yards to be maintained in a neat condition. Community Compliance generally cites lawns/weeds over about 6 inches or any dry vegetation that poses a fire hazard.
What if I just stop watering during drought?
Brown turf alone is not a violation, but it cannot become tall, weedy, or a fire hazard. State law (Civil Code §1940.10 and Gov. Code §53087.7) bars cities and HOAs from fining you simply for letting a lawn go brown during a Governor-declared drought.
