Single-family private residential landscaping is not affected by AB 1572's non-functional turf irrigation ban.

California law expressly permits residential rainwater harvesting from rooftops under the Rainwater Capture Act of 2012 (Cal. Water Code § 10574), and no water-right permit is required. Rain barrels and non-potable cisterns under 5,000 gallons are typically exempt from building permits in the Sonoma region when basic safety criteria are met.

The City does not mandate native plants by species list, but SMC § 19.40.060 (Landscape standards) and SMC Ch. 14.32 require drought-tolerant plantings in conformance with the city's low-water-use landscaping ordinance, and prohibit turf in commercial landscapes except in active play areas.

The City of Sonoma has no ordinance prohibiting residential artificial turf, and California Civil Code § 4735 forbids homeowners associations from banning synthetic grass on a member's separate-interest property. Commercial/nonresidential turf is treated as 'non-functional' under SMC Ch. 14.32 / AB 1572 and is generally limited.
