Corona requires grass and weeds to stay under about 6 inches under CMC Chapter 8.20 nuisance rules. Corona Fire runs an annual Weed Abatement Program for hillside and WUI parcels.
Corona enforces vegetation height through CMC Chapter 8.20 (Nuisances) and Title 9 fire/weed abatement provisions. Residential property owners must mow lawns and cut weeds to prevent fire hazards, harborage for vermin, and visual blight. While the code does not state a single citywide numeric height for all turfgrass, enforcement practice treats grass and weeds taller than 6 inches as a nuisance, and Corona Fire's annual Weed Abatement Program targets parcels with combustible vegetation taller than 6 inches within 100 feet of structures or roadways. The city issues a courtesy notice followed by a 30-day compliance period; after that, contractors abate at owner expense plus an administrative fee added to the property tax roll. Hillside parcels and properties adjacent to the Cleveland National Forest fall under stricter Riverside County Fire (which contracts with Corona) defensible space rules under PRC §4291. Front-yard landscaping must also comply with the Model Water Efficient Landscape Ordinance (MWELO) and CMC drought provisions. Tenants are responsible if leases assign yard duties, but ultimate liability rests with the owner of record. Repeat offenders face escalating administrative citations under CMC Chapter 1.16.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Corona code enforcement directly for current fines, enforcement procedures, and hearing options.
