Grass Height Limits
Hawthorne sets no numeric lawn-height limit. Instead, overgrown, dead, or decayed weeds and vegetation visible from a public right-of-way or neighboring property are treated as a property-maintenance nuisance. Code enforcement issues notice, and owners must abate within the time the notice specifies.

Some RestrictionsTree Trimming
Hawthorne requires a permit from the Director of Parks and Recreation to cut, trim, prune, plant, remove, or interfere with any tree, shrub, or plant in a city street, park, parkway, alley, or city property. Trees on private property are not subject to that permit, but owners must keep them from becoming a hazard.

Some RestrictionsTree Removal & Heritage Trees
Removing a tree in a Hawthorne street, parkway, park, alley, or on city property requires a permit from the Director of Parks and Recreation - the same authority that governs trimming. The code does not impose a citywide heritage-tree permit for trees on private property; private-tree removal is generally unregulated unless tied to development review.

Some RestrictionsWater Restrictions
Hawthorne's Water Conservation Program assigns watering days by address parity and limits landscape irrigation to before 8 a.m. and after 6 p.m., not within 48 hours of measurable rain. It bans hosing down hard surfaces, runoff, and washing vehicles without a shut-off nozzle, with tighter limits in higher drought stages.

Some RestrictionsRainwater Harvesting
Hawthorne has no ordinance restricting rain barrels or cisterns, and the city encourages conservation. Rainwater collection is governed mainly by California rules: rooftop rainwater harvesting needs no state water-right permit, and rain-barrel/cistern systems up to 5,000 gallons used for gravity-fed outdoor irrigation are exempt from a plumbing permit.

Few RestrictionsNative Plants
Hawthorne does not mandate native plants, but its Water Efficient Landscaping ordinance pushes new and rehabilitated landscapes toward low-water, climate-appropriate plants and heavy mulching under California's MWELO. Residents replacing lawns with drought-tolerant plants can also tap regional SoCal Water$mart turf-replacement rebates.

Few RestrictionsArtificial Turf
Hawthorne does not ban artificial turf, but its Water Efficient Landscaping ordinance treats synthetic turf differently from living plants, and residential development standards govern front-yard and setback landscaping. Note: the regional SoCal Water$mart turf-replacement rebate does NOT count synthetic turf as an approved lawn conversion.

Some RestrictionsComposting
Hawthorne runs a mandatory organic-waste program under California SB 1383: residents must keep food scraps, food-soiled paper, and yard/green waste out of the trash and place them in the organics cart for collection. Backyard composting is allowed and encouraged, and MWELO landscape projects must use compost and mulch.
