California’s Assembly Bill 1572 non-functional turf ban prohibits using drinking water to irrigate decorative grass on commercial, industrial, institutional, and homeowners’ association properties, with deadlines phasing in between January 1, 2027 and January 1, 2031 depending on who owns the property. Recreational grass is untouched. Private single-family yards are untouched. What the law targets is the ornamental strip in front of an office park, the median lawn nobody walks on, and the HOA common-area turf that exists only to look green from the street.
What Counts as Non-Functional Turf
Non-functional turf is grass that exists purely for appearance and gets no regular human foot traffic for recreation or community events. The lawn in front of an office building that nobody sets foot on, the strips lining a commercial parking lot, the turf in a road median: if people don’t play, exercise, or gather on it, the statute treats it as decorative.1LegiScan. California Assembly Bill 1572 – Potable Water: Nonfunctional Turf
Functional turf sits in a “recreational use area” or community space where people actually use it. The statute defines recreational use areas broadly, covering sports fields, golf courses, playgrounds, picnic grounds, and pet exercise areas, whether the use is organized or informal.2California Legislative Information. Assembly Bill 1572 Parks, cemeteries, and school playing fields qualify. One boundary matters: turf that is fenced off or otherwise blocked from access does not count as functional even if it sits inside a park or community area.1LegiScan.

Who Has to Comply and Who Doesn’t
AB 1572 reaches large-scale landowners. That means commercial properties like shopping centers and office complexes, industrial sites, and institutional properties like hospitals, universities, and government buildings. Homeowners associations, common interest developments, and community service organizations are covered too, but only for their shared common areas.3California Legislative Information. California Water Code 10608.14
Private residential yards are outside the law entirely. If you own a single-family home and water your front lawn, AB 1572 does not apply to you. The same holds for the private yard of a townhome or condo unit you maintain yourself. The HOA’s common-area grass is a separate question, but the grass on your own lot is not regulated by this statute.
Recreational turf inside an HOA or community development stays permitted. A shared playground, dog park, or gathering lawn that residents actually use qualifies as functional turf and can still be watered with drinking water. The question is whether people use the grass, not whether it looks nice from the curb.
Compliance Deadlines by Property Type
The law phases in on a staggered schedule. Government properties go first, and the other categories follow over four years:
- January 1, 2027: Properties owned by the Department of General Services (state-owned buildings) and properties owned by local governments, regional public agencies, and public water systems.
- January 1, 2028: All commercial, industrial, and remaining institutional properties.
- January 1, 2029: Common areas of HOAs, common interest developments, and community service organizations.
- January 1, 2031 (or later): Government properties in disadvantaged communities. This deadline only takes effect once the state makes funding available to help those properties convert, whichever comes later.
These dates come directly from the Water Code.3California Legislative Information. California Water Code 10608.14 The 2031 extension applies only to government-owned properties within disadvantaged communities. A privately owned commercial building in a disadvantaged community still faces the standard 2028 deadline.
Exceptions to the Ban
The ban targets potable (drinking) water only. Properties that irrigate with recycled or reclaimed water are not affected, no matter whether the turf is functional or decorative.3California Legislative Information. California Water Code 10608.14 If your property already has a recycled water connection or purple-pipe system, decorative grass irrigated through it can stay.
Trees and other perennial non-turf plants are explicitly protected. Even after the decorative grass around them must stop receiving drinking water, you can still irrigate the trees and established plantings as needed to keep them healthy.3California Legislative Information. California Water Code 10608.14 Water agencies recommend converting overhead spray to drip irrigation in these areas so you water the trees without watering the surrounding turf, though that conversion is a best practice, not a statutory requirement. The law also allows potable water use when an immediate health or safety situation demands it.
Hardship Extensions
The State Water Resources Control Board can push back a property’s deadline by up to three years if the owner shows good cause, including economic hardship, a critical business need, or potential impacts to health or safety.3California Legislative Information. California Water Code 10608.14 This is not a blanket extension for inconvenience. The board reviews requests individually, and the property owner carries the burden.
Synthetic Turf
Replacing ornamental grass with artificial turf is not prohibited under AB 1572, but water agencies generally do not recommend it, and most rebate programs will not reimburse for it. Owners considering synthetic turf should check their local water agency’s policies first, since the replacement may satisfy the irrigation ban without qualifying for financial incentives.
Self-Certification Requirements
Owners cannot simply stop watering and consider the matter closed. Any property with more than 5,000 square feet of irrigated area has to file a formal self-certification with the State Water Resources Control Board on a set schedule:
- Commercial, industrial, and institutional properties: First certification due June 30, 2030, then every three years through 2039.
- HOAs, common interest developments, and community service organizations: First certification due June 30, 2031, then every three years through 2040.
These filings confirm the property complies with the irrigation restrictions.3California Legislative Information. California Water Code 10608.14 Properties under 5,000 square feet of irrigated area are still bound by the irrigation ban but do not file paperwork with the state board. The board is developing a standardized certification form, so owners approaching their deadline should watch the board’s website.
Public water systems have their own obligation. By January 1, 2027, every public water system in California must update its rules and policies to incorporate AB 1572 and communicate those requirements to customers.3California Legislative Information. California Water Code 10608.14 Your water bill or account notices should eventually spell out what the law requires of your property type.
Enforcement and Penalties
Enforcement authority is spread across public water systems, cities, and counties within their jurisdictions.4LegiScan. California Assembly Bill 1572 At the state level, the penalty framework draws on Water Code Section 1846, which allows civil liability of up to $1,000 per day for each day a violation continues. Local water agencies can also impose penalties under their own ordinances, and those schedules vary. Some agencies use escalating fines that begin with a written warning and climb from $125 for a first violation to $2,000 or more for repeated offenses. Where a local agency has adopted its own schedule, that schedule controls alongside the state-level exposure.
Starting July 1, 2030, the State Water Resources Control Board will begin compliance audits, cycling through California’s hydrologic regions so each region gets audited once every five years. Audits rely on visual inspections of properties with large landscaped areas, properties with unusually high water consumption, and addresses that have drawn water-waste complaints within the prior year.4LegiScan. California Assembly Bill 1572 The board can coordinate with local water systems to identify potential violators, so high water usage at a commercial property after the compliance deadline is a red flag that could trigger an inspection.
Rebates for Turf Conversion
Tearing out ornamental grass and replanting with drought-tolerant landscaping is not cheap, but rebate programs help offset the cost. California does not run a single statewide rebate. Programs are administered by regional water agencies, and amounts vary by location. The state’s Save Our Water program maintains a lookup tool where owners can enter a ZIP code to find rebates through their local agency.
As a benchmark, the Metropolitan Water District of Southern California offers $2 per square foot for turf conversion, up to 5,000 square feet per year, and $100 per tree planted as part of the conversion, up to five trees ($500 total). Local agencies within Metropolitan may stack additional incentives on top of that base.5SoCal Water$mart. Turf Replacement Program Most programs require applying and receiving approval before starting the project, not after. Missing that step usually forfeits the rebate.
Programs also set minimum standards for the replacement landscape, including a minimum number of plants per square foot, a stormwater retention feature, and conversion of overhead spray sprinklers to drip or micro-spray. Synthetic turf and bare hardscape generally do not qualify. Confirm your local program’s specific requirements before breaking ground, since rules differ between agencies and rebate funds can run out.
