Vista, CA Landscaping Rules: Native Plants (2026)

Vista implements the California Model Water Efficient Landscape Ordinance (MWELO) per Government Code Section 65595 for new construction and rehabilitated landscapes over 500 square feet. MWELO requires a landscape plan demonstrating water efficiency with a maximum applied water allowance. Native and drought-tolerant plants from the San Diego region are encouraged and reduce irrigation requirements. The Vista Irrigation District promotes water-wise landscaping and may offer turf replacement rebates for converting traditional lawns to drought-tolerant plantings. California AB 1881 requires cities to enforce MWELO, and AB 2104 prohibits HOAs from fining homeowners for reducing or eliminating turf during drought declarations. Vista's inland climate zone is well-suited for California native plants including coastal sage scrub species, manzanita, California buckwheat, and native grasses. Community Development at (760) 639-6100 handles MWELO compliance for new development. The Vista Irrigation District at (760) 597-3100 provides landscaping resources and rebate information.
