Carson, CA
Los Angeles County
Carson has no ordinance mandating native plant species, but the Model Water Efficient Landscape Ordinance (MWELO, CCR Title 23 §§490–495) effectively favors low water-use (often California-native or Mediterranean) species for new and rehabilitated landscapes ≥500 sq ft by capping the Maximum Applied Water Allowance via plant factors from the WUCOLS database.

South Gate does not restrict native or drought-tolerant landscaping; state law affirmatively protects it. California Civil Code § 4735 prohibits HOAs from banning low-water plants, and Government Code § 53087.7 plus AB 1572 (2023) further restrict watering of decorative turf at public/commercial sites. South Gate must comply with MWELO (CCR Title 23 § 490 et seq.) for new and rehabilitated landscapes meeting the threshold.

No — there is no native plant mandate. However, MWELO's water budget effectively favors low water-use species, many of which are California natives.
Can my HOA make me remove drought-tolerant plants?
No — California Civil Code §4735 prohibits HOAs from banning or requiring removal of drought-tolerant or low-water-use landscaping.
South Gate FAQ
Can my HOA force me to keep a lawn?
No. Civil Code § 4735 prohibits HOAs from banning low-water-using plants or requiring lawn during a state-declared drought emergency.
Does MWELO apply to my front-yard redo?
If the project requires a permit and the landscaped area is ≥ 500 sq ft (residential), MWELO efficiency standards apply. ≥ 2,500 sq ft requires the full Landscape Documentation Package.
