The Model Water Efficient Landscape Ordinance (MWELO, CCR Title 23 §§490 et seq.) caps turf at 25% of landscape area for residential prescriptive-compliance projects and requires climate-appropriate plant selection. Cal. Civil Code §4735 prohibits HOAs from banning low-water plants. Jurupa Valley applies MWELO through its zoning landscape standards in Title 9.

Riverside County
Riverside Municipal Code Chapter 19.570 — Water Efficient Landscaping & Irrigation — implements California's Model Water Efficient Landscape Ordinance (MWELO). New and retrofit landscapes ≥500 sq ft must meet a Maximum Applied Water Allowance that effectively requires drought-tolerant or California-native species over most of the landscaped area.

Jurupa Valley FAQ
Does Jurupa Valley require native plants in new landscaping?
Not specifically native — but MWELO requires climate-appropriate, low-water plant selection, and caps turf at 25% of the landscape area under the prescriptive compliance pathway. California natives easily satisfy these standards.
Can my HOA force me to keep a lawn instead of natives?
No. Cal. Civil Code §4735 prohibits HOAs from enforcing rules that effectively prevent installation of low-water, drought-tolerant landscaping, including native-plant gardens.
Riverside FAQ
Does RMC 19.570 force me to plant only natives?
No — the ordinance is performance-based via the MAWA water budget. But because turf and high-water ornamentals consume so much of the budget, achieving compliance on most lots effectively means devoting the majority of the area to low-water California-native, Mediterranean, or other drought-tolerant species.
Does the City require a native plant list?
RMC 19.570 incorporates the state MWELO appendix, which references the WUCOLS IV (Water Use Classification of Landscape Species) database for plant factors. Native and drought-tolerant species in WUCOLS 'Very Low' and 'Low' categories are the practical pathway to compliance.
Does AB 1572 affect my front-yard lawn?
Not if it's a single-family home. AB 1572 (Water Code §115922) phases in a ban on irrigating non-functional turf only on (1) public agency property, (2) commercial/industrial/institutional property, and (3) HOA common areas — starting 2027, 2028, and 2029 respectively. Single-family residential is expressly excluded.
