California AB 1572: Non-Functional Turf Ban, Deadlines, and Penalties

California’s Assembly Bill 1572 bans using drinking water to irrigate purely decorative grass on commercial, industrial, institutional, and homeowners’ association common-area properties, with compliance deadlines phasing in between January 1, 2027 and January 1, 2031 depending on who owns the property. The California non-functional turf ban under AB 1572 does not reach private residential yards, and it does not touch grass that people actually use for recreation. If you own or manage a covered property, the questions that matter are which of your grass counts as non-functional, when your deadline hits, and what happens if you keep watering past it.

What Counts as Non-Functional Turf

Non-functional turf is grass that exists for appearance and gets no regular foot traffic for recreation or community events. The strips lining a commercial parking lot, the lawn in front of an office building that no one walks on, the turf in a road median: all decorative, all covered.¹

Functional turf is grass in a recreational use area or community space where people actually use it. The statute defines recreational use areas broadly, including sports fields, golf courses, playgrounds, picnic grounds, and pet exercise areas, whether the use is organized or informal.² Parks, cemeteries, and school playing fields all qualify. One boundary matters here: turf that is fenced off or otherwise blocked so people cannot access it does not count as functional, even if it sits inside a park.¹ The test is use, not location or appearance.

Who the Law Applies To

AB 1572 reaches large-scale landowners. Commercial properties like shopping centers and office complexes, industrial sites, and institutional properties like hospitals, universities, and government buildings all fall within the ban. Homeowners associations, common interest developments, and community service organizations are covered too, but only for their shared common areas.³

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 goes for the backyard of a townhome or condo that you maintain individually. Your HOA’s shared common-area grass is a separate matter, but the grass on your own lot is not regulated by this statute.

Recreational grass inside an HOA or community development also stays permitted. A shared playground, dog park, or gathering lawn that residents actually use qualifies as functional and can still be irrigated with drinking water.

Compliance Deadlines by Property Type

The law phases in on a staggered schedule, with government properties first and the remaining categories following over four years:³

January 1, 2027: Properties owned by the state Department of General Services, 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 located in disadvantaged communities. This deadline does not take effect until the state makes funding available to help those properties convert to drought-tolerant landscaping, whichever comes later.

The 2031 extension applies only to government-owned properties in disadvantaged communities. A privately owned commercial building in a disadvantaged community still faces the standard 2028 deadline. Disadvantaged communities are identified primarily through CalEnviroScreen 4.0, along with certain previously designated tracts and federally recognized tribal lands.⁴

Exceptions

The ban targets potable water. Properties that irrigate with recycled or reclaimed water are not affected, regardless of whether the turf is decorative.³ If your property already draws from a recycled water connection or purple-pipe system, you can keep watering ornamental grass through it.

Trees and other perennial non-turf plants are explicitly protected. Even after the decorative grass around them must stop receiving drinking water, you can continue to irrigate trees and established plantings as needed to keep them healthy.³ Water agencies recommend converting overhead spray systems to drip irrigation in these areas so the trees get water without the turf getting watered too, but that conversion is a best practice, not a statutory requirement. The law also permits 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 health and safety impacts.³ The board evaluates requests individually, and the burden is on the property owner.

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. If you are considering synthetic turf, check your local water agency’s policies first. The replacement may satisfy the irrigation ban but will not usually qualify for financial incentives.

Self-Certification

Covered properties do not simply stop watering and move on. Any covered property with more than 5,000 square feet of irrigated area must file a self-certification with the State Water Resources Control Board on a set schedule:³

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.

Properties under 5,000 square feet of irrigated area are still bound by the irrigation ban but do not file certifications with the state board. The board is developing a standardized certification form, so property managers approaching their deadline should watch the board’s website for the official document.

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 the requirements to customers.³ Expect your water account notices to spell out what the law requires of your property type.

Enforcement and Penalties

Public water systems, cities, and counties all have authority to enforce AB 1572 within their jurisdictions.⁵ 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 impose penalties under their own ordinances as well, and those schedules vary. Some agencies have published escalating structures that start with a written warning and climb from $125 for a first violation to $2,000 or more for repeat offenses. Where a local agency has adopted its own penalty schedule, that schedule applies 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. The audits rely on visual inspections and target properties known to have large landscaped areas, properties with unusually high water consumption, and addresses that have drawn water-waste complaints in the prior year.⁵ The board can coordinate with local water systems to flag likely violators, which means high usage at a commercial property after the deadline is a red flag that can trigger an inspection.

Rebates for Turf Conversion

Removing ornamental grass and replacing it with drought-tolerant landscaping costs money, and rebate programs help offset that cost. California does not run a single statewide rebate. Programs are administered by regional water agencies, and the amounts vary. The state’s Save Our Water program maintains a tool where property 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, plus $100 per tree planted as part of the conversion, up to five trees for $500 total. Local agencies served by Metropolitan may stack additional incentives on top of that base amount.⁶ Rebate programs typically require applying and getting approval before you start the project. Starting work first usually forfeits the rebate.

Most programs also set minimum standards for the replacement landscape. Common requirements include a minimum number of plants per square foot of converted area, a stormwater retention feature, and conversion of overhead spray sprinklers to drip or micro-spray systems. Synthetic turf and bare hardscape generally do not qualify. Confirm your local program’s specific requirements before breaking ground, and apply early. Rebate funds can run out.
