Full Breakdown

California's Model Water Efficient Landscape Ordinance (MWELO), adopted locally by Moreno Valley, requires new residential landscapes over 500 square feet (or 2,500 square feet for projects without a permit) to meet maximum applied water allowance calculations favoring low-water plants. AB 1572 (2023) phases out the use of potable water for non-functional turf on commercial, industrial, and HOA common areas statewide by 2027-2031. California native plants, such as California poppy, cleveland sage, manzanita, deergrass, matilija poppy, and toyon, thrive in Moreno Valley's hot, dry climate and provide habitat for pollinators and birds.

California Civil Code section 4735 prohibits homeowner associations from requiring turf or banning drought-tolerant landscaping, and during a declared drought emergency, HOAs cannot enforce any rule that requires watering. EMWD and Metropolitan Water District of Southern California offer turf-replacement rebates, typically $2-$3 per square foot of lawn removed, for homeowners converting to native and drought-tolerant designs. Mulch is required at 3 inches minimum depth in planting areas. Invasive plants such as fountain grass (Pennisetum setaceum) and giant reed (Arundo donax) are prohibited in new landscape installations. Proper plant spacing, hydrozoning, and efficient irrigation (drip preferred) are MWELO requirements for any permitted landscape.

Frequently Asked Questions

Can my HOA make me keep a lawn?
No. Civil Code 4735 protects your right to install drought-tolerant landscaping, including replacing lawn with native plants.
Are there rebates for replacing my lawn?
Yes. EMWD and MWD offer turf-replacement rebates typically $2-3 per square foot. Apply before starting your project.
Do I need a permit for landscape changes?
Not for typical residential replanting. New installations over 500 sq ft or irrigation changes may trigger MWELO review.
