Ontario FAQ
Does Ontario have a specific grass height limit?
The code uses a nuisance standard rather than a strict number, but Code Enforcement generally acts on dry grass or weeds over roughly six inches or that create fire or pest risk.
Who mows the strip between sidewalk and curb?
The adjacent property owner is responsible for maintaining parkway strips, including mowing, weed control, and keeping them clear of debris.
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.
