The lawn outside a Rancho Cucamonga commercial building is heading for a budget reckoning: January 1, 2028.
That is when AB 1572 prohibits potable-water irrigation of nonfunctional turf on commercial and industrial properties.
Waiting for the later certification date leaves an owner two and a half years late. [1]
Cucamonga Valley Water District adopted Ordinance No. 2026-6-2 in June 2026, amending its water-efficiency rules at §4.20.030. [2]
For a strip-center owner, the questions are blunt: what does replacement cost, when does the money leave, and whose account absorbs it?
The water source is the dividing line
The law restricts drinking-water use. It does not ban owning grass or order every commercial lawn removed.
The State Water Board lists grass bordering signs, buildings and sidewalks, and grass in parking lots, as examples of nonfunctional turf.
Grass used for recreation or community gatherings falls into a different category. [3]
A “common area” label on a rent roll does not establish how the grass is used. That takes a site inventory.
CVWD exempts turf irrigated with recycled water. Check the supply and irrigation layout before treating every green strip alike. [2]
Do not starve established trees to solve a turf problem.
The statute permits potable watering necessary for trees, other perennial nonturf plants, and immediate health-and-safety needs. [1]
Two deadlines. One budget.
CVWD adopted its ordinance in June.
Potable-water irrigation of nonfunctional commercial turf is restricted.
For covered owners with more than 5,000 sq ft of irrigated area.
The reporting date is not an extension. Exceptions and definitions matter. Sources: Water Code §10608.14 and CVWD.
Put a number in the reserve
This is a budgeting scenario, not a contractor quote: 8,000 square feet at an assumed $8 all-in conversion cost per square foot means $64,000.
An assumed 15% contingency brings the requirement to $73,600, before rebates. Over 12 months, that reserve needs about $6,133 monthly.
Leaving the capital-plan line blank will not erase next year’s bill.
The model promises no savings, rebate or tenant reimbursement. Each needs evidence; an estimate cannot establish what a lease lets an owner recover.
Separate design, installation, irrigation changes and contingency. One tidy allowance can conceal four sources of overrun.
A rebate can disappear before the grass does
SoCal Water$mart requires an approved commercial reservation before work begins. Early removal can disqualify a project; current terms also exclude dead or dying turf. [4]
Approved projects have 180 days to finish and request payment.
Funding and rebate amounts can change. Confirm both before committing them to a budget. [5]
For covered commercial and industrial owners with over 5,000 square feet of irrigated area, certification starts June 30, 2030.
It repeats every three years through 2039. That reporting threshold does not exempt smaller commercial properties from the 2028 irrigation restriction. [1]
Build the file now: measured area, water source, documented use, funded scope and any approved rebate reservation.
A green frontage is an appearance. A funded deadline is an asset-management decision.
