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.
San Bernardino FAQ
How tall can my grass legally be in San Bernardino?
There is no single inch threshold citywide, but front-yard grass over roughly 6 in. draws nuisance citations, and foothill parcels must be cut to 4 in. in fire season.
What if I cannot mow my property on time?
Contact San Bernardino Code Enforcement or the county Hazard Abatement program before the deadline; extensions are rare but possible for documented hardship.
Can the county mow my property and bill me?
Yes. If you miss the abatement deadline, the county contracts the work and adds it to your property tax bill as a lien or special assessment.
