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

The City of Perris regulates grass and vegetation through two separate chapters of its Municipal Code. For everyday occupied properties, Chapter 7.42 (Landscape Maintenance) makes it unlawful to allow 'overgrown vegetation including trees, shrubbery, groundcovers, lawns and other plantings' that diminishes a property's appearance compared to neighbors, and also bars dead, decayed, or diseased vegetation and bare/unsightly yards (PMC 7.42.020). This is a qualitative standard tied to appearance and horticultural norms rather than a fixed lawn height. A specific numeric limit appears only in the weed-abatement context: PMC 7.08.045 requires that on parcels subject to abatement, 'Grasses located on the property shall be cut to a height not exceeding six inches.' That six-inch standard targets fire-hazard weeds and vacant or large parcels, not a manicured lawn. Enforcement of overgrowth on occupied lots starts with a notice of violation; under PMC 7.42.030 the owner has ten days to begin corrections. Because Perris served some areas directly and now relies on Eastern Municipal Water District (EMWD) for water, mowing and irrigation must also respect EMWD water-use rules. There is no California statewide residential grass-height law, so the six-inch figure is purely a Perris weed-abatement standard.
