AB 1572 Is Here: Why Commercial Property Owners Need an Arborist Now
California's Assembly Bill 1572 isn't a distant regulatory concern—it's already in effect, and commercial property owners across the state are running out of time to comply. If your property features decorative turf irrigated with potable water, the clock is ticking.
What AB 1572 Actually Requires
AB 1572 prohibits the use of potable water to irrigate non-functional turf on commercial, industrial, and institutional properties. In plain terms: if your grass is purely decorative—no recreation, no civic use—it cannot be watered with drinkable water. The bill applies to office parks, retail centers, HOA common areas, and similar properties statewide.
This isn't a voluntary sustainability initiative. Non-compliance carries real consequences, and state regulators are not waiting for stragglers to catch up.
When Does It Take Effect?
Compliance deadlines under AB 1572 are already rolling out in phases. Large water agencies were required to begin enforcing restrictions first, with broader mandates expanding across the state through 2026 and 2029. Waiting until your specific deadline arrives before taking action is a costly mistake—and here's why.
Why You Cannot Afford to Wait
Turf removal sounds straightforward. It isn't. Most commercial landscapes have mature trees and turf sharing the same irrigation zones. For years, those trees have relied on the frequent, shallow watering that lawn care requires. When you shut off the sprinklers or bring in machinery to strip the turf, you're not just removing grass—you're cutting off the primary water source for every tree in that zone.
The consequences can be severe:
Drought shock sets in quickly when trees lose their regular irrigation without a proper transition plan
Mechanical turf removal can shred the absorbing roots that sit within the top 12 to 18 inches of soil, causing irreversible damage
Improper mulching or irrigation changes can suffocate root systems rather than support them
Replacing a mature tree costs far more—financially and aesthetically—than protecting it during the conversion process.
Why Your Arborist Should Be Your First Call
Before you contact a landscaping crew, contact a certified arborist. This is not an optional step—it's the most important one.
An arborist will assess your trees' root zones before any equipment arrives on site, establish protective barriers around your most valuable canopy, and design a gradual watering transition that prevents drought shock. They'll also help you convert spray irrigation to deep-root drip systems, recommend the right mulch depth and type to retain soil moisture, and perform strategic pruning to reduce overall water demand during the transition.
Bringing in an arborist early means your turf conversion protects your trees rather than sacrifices them.
Don't Wait for a Deadline to Force Your Hand
Property managers who wait until the last moment face two problems at once: the pressure of a compliance deadline and the damage caused by a rushed turf removal. That's a difficult and expensive position to be in.
