Las Vegas Lawn Watering Rules & Schedule

Official irrigation schedule, municipal water waste penalties, and local agronomic guidelines for Las Vegas homeowners.

Essential Compliance Takeaway

Irrigation in Las Vegas is regulated by Southern Nevada Water Authority (SNWA). Watering outside your assigned days or hours is a citable violation, and the penalties below are the published ones.

Seasonal Irrigation Schedule

Enforced Policy

Summer Schedule (Critical Window)

Peak Heat

Assigned watering days based on address. May 1–Aug 31: 6 days/week, Sunday prohibited. Watering is strictly prohibited from 11 a.m. to 7 p.m.

Spring & Fall Schedule

Mar 1–Apr 30 & Sep 1–Oct 31: 3 days/week.

Winter Schedule

Nov 1–Feb 28: 1 day/week.

Water Waste Fines & Enforcement

Water waste fines start at $80 and double for each subsequent violation, up to $5,120.

Las Vegas Soil & Microclimate Strategy

The Las Vegas Valley sits on a deep layer of caliche (cemented calcium carbonate). Water does not drain through caliche; it pools on top. SNWA recommends 'cycle and soak' watering: run sprinklers for 4 minutes, wait an hour, repeat 3 times.
