The Jan 1, 2027 Law & SNWA Rebates, Explained
Nevada's AB356 prohibits using Colorado River water to irrigate decorative grass at non-single-family properties starting January 1, 2027. Here's the law in plain English, the commercial rebate tiers, worked rebate math, and a planning timeline counting back from the deadline.

The Law in Plain English (AB356)
In 2021, the Nevada Legislature passed Assembly Bill 356. Its core rule: starting January 1, 2027, it is illegal to use water from the Colorado River — which supplies about 90% of Southern Nevada's water — to irrigate nonfunctional turf.
What Counts as Nonfunctional Turf?
Grass that exists only to be looked at — never used. The classic examples:
- Medians, traffic circles, and roadside strips
- Entry monuments and gatehouse landscaping
- Parking-lot islands and walkway borders
- Decorative common-area lawns nobody plays on
Grass actually used for recreation — play fields, large gathering lawns — is generally considered functional. The line isn't always obvious, which is why SNWA can review your property and classify each area.
Who It Applies To — and Who It Doesn't
Applies to: HOA common areas, apartment/multifamily properties, office parks, retail centers, commercial properties, and municipal properties across Southern Nevada.
Exempt: single-family homes are excluded from the ban. Schools, parks, and golf courses are also excluded per the reporting on the law.
Waivers: properties can apply to SNWA for a waiver by demonstrating their grass meets the definition of functional turf. Details and applications are at snwa.com.
⏰ Enforcement: What We Know (and Don't)
In late September 2026, the Las Vegas Valley Water District announced plans to classify irrigation of decorative grass as water waste starting January 1, 2027, with proposed fines scaling by water-meter size — from $80 for a first offense on a residential-sized meter up to $5,120 for a fifth offense on the largest meter. But those fines were still going through approval at the time, and the law itself is the subject of an ongoing lawsuit challenging the ban. Bottom line: enforcement details are evolving. Check current terms at snwa.com or with your local water agency rather than relying on any single source — including this page.
SNWA Commercial Rebate Tiers
The SNWA Water Smart Landscapes (WSL) program pays businesses, HOAs, and multifamily properties to replace water-thirsty grass:
| Tier | Commercial / HOA / Multifamily rate |
|---|---|
| First 10,000 sq ft converted | $5.00 / sq ft |
| Every sq ft after that | $1.50 / sq ft |
| Each new tree planted (Tree Enhancement Program) | $100 / tree |
Rates verified from snwa.com and SNWA announcements (Aug 2026). Terms change — check current terms at snwa.com. Per SNWA, the commercial tiers apply "without regard to passage of time or number of project phases" — phasing across budget years doesn't reduce your rebate.
⚠️ Critical: Get SNWA Approval Before Touching the Grass
SNWA requires a pre-conversion site visit and approval before any grass is removed. Removing grass without SNWA's approval can make the project ineligible for the rebate. Rebate applications surge in spring and fall, which lengthens site-visit wait times — apply early and build the wait into your timeline.
Worked Math: A 20,000 Sq Ft Conversion
Here's what a typical mid-size commercial or HOA common-area project looks like on paper:
| Line item | Amount |
|---|---|
| Rebate: 10,000 sq ft × $5.00 | $50,000 |
| Rebate: 10,000 sq ft × $1.50 | $15,000 |
| Plus 25 new trees × $100 | $2,500 |
| Total rebate back | $67,500 |
What Does the Installation Cost?
Professional commercial turf installation typically runs $8–$18 per square foot, depending on scale, site work (demo, grading, drainage), irrigation removal, and turf specification. Larger projects often price better per foot. At $8–$18/sq ft, a 20,000 sq ft project lands around $160,000–$360,000 installed — against which the $65,000–$67,500 rebate is a meaningful offset, before counting eliminated mowing contracts, irrigation repairs, and water bills.
Cost ranges are hedged planning estimates compiled from published 2026 industry pricing guides (commercial installs commonly cited at $8–$14/sq ft with volume pricing at scale; specialty systems and difficult site work run higher). They are not quotes — your contractor's bid determines the real number.
💧 The Water Math
SNWA estimates that a square foot of grass needs about 73 gallons of water per year to irrigate, versus ~18 gallons for drip-irrigated landscaping. A 20,000 sq ft conversion saves roughly 1.1 million gallons a year — which is also why the water bill drop alone can be dramatic.
Planning Timeline: Working Back From Jan 1, 2027
As of October 2026, roughly three months remain. This is a start-now timeline, not a someday timeline.
- October 2026 — Assess now: Get SNWA's free expert review and grass-classification maps for your property. Start contractor conversations immediately — this is the step everything else waits on.
- October–November 2026 — Bid and approve: Site walks, itemized bids, board or management approval, and the SNWA pre-conversion site visit and approval. Remember: no grass removed before SNWA signs off.
- November–December 2026 — Build: Smaller and mid-size conversions can complete in this window. Larger multi-acre projects should be phased, with nonfunctional areas at minimum taken off irrigation by the deadline.
- January 1, 2027 — Deadline: Irrigating nonfunctional turf with Colorado River water becomes illegal. Properties should be converted, or at minimum have irrigation to nonfunctional areas shut off.
⏰ If You Can't Finish in Time
The law bans irrigating nonfunctional turf — so even if construction phases run past the deadline, properties should be prepared to stop watering those areas on January 1, 2027. Talk to SNWA about your timeline and to your contractor about a phasing plan that gets the water off first.

Compliance & Rebate Questions
What counts as nonfunctional turf?
Grass that serves only a decorative purpose and isn't used for recreation — medians, entry monuments, parking-lot islands, roadside strips, decorative common-area lawns. Grass used for play or recreation is generally functional. SNWA can provide maps classifying the grass at your property.
Can we get a waiver to keep watering decorative grass?
Properties can apply to SNWA for a waiver by demonstrating their grass meets the definition of functional turf. Waiver criteria and applications are handled through SNWA — check current details at snwa.com.
What are the commercial rebate rates?
$5/sq ft for the first 10,000 sq ft converted, $1.50/sq ft after that, plus $100 per new tree planted. Terms change — check current terms at snwa.com. And remember: SNWA requires a pre-conversion site visit and approval before any grass is removed.
What does commercial turf conversion cost per square foot?
Typically $8–$18/sq ft installed, depending on scale, site work, drainage, irrigation removal, and turf specification — with better per-foot pricing at larger scales. These are planning estimates, not quotes; your contractor's bid sets the real number.
What if we can't finish converting by January 1, 2027?
The law bans irrigating nonfunctional turf with Colorado River water — so at minimum, be prepared to stop watering those areas by the deadline. Phased construction can continue past it. Discuss your timeline with SNWA and your phasing plan with your contractor.
