Newport Beach, CA Landscaping Rules: Native Plants (2026)

Newport Beach implements California's Model Water Efficient Landscape Ordinance (MWELO) requiring water-efficient landscaping for new construction, rehabilitated landscapes, and projects with 500 square feet or more of landscaped area. Landscape plans must demonstrate a Maximum Applied Water Allowance calculated based on plant water needs and irrigation efficiency. California native plants and Mediterranean climate-adapted species count favorably in water budget calculations due to their low water requirements. The city's approved plant palette for public medians and streetscapes prioritizes native coastal sage scrub and drought-tolerant species. Within the Coastal Zone, the Local Coastal Program encourages preservation of native habitat and restoration plantings using locally sourced native species. The Environmental Quality Affairs Committee advises on native plant policies. Homeowners converting turf to native landscaping may qualify for turf replacement rebates through their local water district. The city does not mandate native-only plantings but incentivizes them through reduced water budget requirements.
