Eastvale, CA Landscaping Rules: Grass Height Limits (2026)

Eastvale is an incorporated city with its own code, so grass and lawn maintenance is governed by the EMC rather than Riverside County. EMC Sec. 8.18.030(a)(18) lists 'overgrown vegetation' as a prohibited public nuisance and specifically names 'lawns with grass in excess of six inches in height,' as well as 'hedges, trees, lawns, plants, or other vegetation that are not maintained in a neat, orderly, and healthy manner as a result of lack of adequate mowing, grooming, trimming, pruning, fertilizing, watering, and/or replacement.' The same section also targets vegetation that harbors rats, vermin or insects, that creates a fire hazard, or that overhangs onto public sidewalks, streets or alleys so as to obstruct people or vehicles. Maintenance standards are also reinforced by EMC Sec. 8.18.030(a)(20), which requires visible front and side yards to be mowed and maintained to the satisfaction of the community development director. Enforcement follows the administrative nuisance abatement process: the city issues a notice of abatement with a compliance period, and unresolved conditions can be abated by the city with costs charged to the owner. The standards apply uniformly regardless of any HOA CC&Rs (EMC Sec. 8.18.010(6)).
