Fontana FAQ
How tall can my grass get before Fontana cites me?
The code targets combustible overgrowth and nuisance weeds; dry grass and weeds beyond roughly 6 inches are commonly cited, especially in fire season.
I got a Notice to Abate - what happens if I do not clear the lot?
The city hires a contractor to clear your property and adds the cost, plus administrative fees, as a lien on your property tax bill.
Do maintained lawns and drought-tolerant yards violate the ordinance?
No. The rules target dry, overgrown, or dead vegetation that creates fire or pest hazards - intentional low-water landscaping is fine.
