Westminster CO Water Restrictions 2026
Published: Updated:
Adams / Jefferson County· Colorado
Westminster's voluntary drought watch (effective through April 15, 2026) has ended. The city did not escalate to mandatory restrictions after April 15. Westminster's permanent Water Use Efficiency Program is now the active framework: Even addresses Mon/Wed/Fri, Odd addresses Tue/Thu/Sun, max 3 days/week, no watering 10 a.m. – 6 p.m. No fines under the permanent ordinance for first offences. Westminster manages its supply from Standley Lake and Denver Water and is watching Colorado's worsening drought conditions — a new watch or escalation to mandatory rules is possible if summer conditions deteriorate.
Current Status
Westminster's voluntary drought watch (effective through April 15, 2026) has ended. The city did not escalate to mandatory restrictions after April 15. Westminster's permanent Water Use Efficiency Program is now the active framework: Even addresses Mon/Wed/Fri, Odd addresses Tue/Thu/Sun, max 3 days/week, no watering 10 a.m. – 6 p.m. No fines under the permanent ordinance for first offences. Monitor westminsterco.gov/water for any re-issued watch or escalation if summer conditions deteriorate.
Watering Schedule by Address
Westminster's permanent Water Use Efficiency Program assigns a 3-day-per-week schedule by address. The year-round 10 a.m. – 6 p.m. blackout remains mandatory regardless of drought stage.
| Group | Watering Days |
|---|---|
| EVEN-numbered addresses | Monday, Wednesday & Friday |
| ODD-numbered addresses | Tuesday, Thursday & Sunday |
| Year-round Westminster ordinance | No sprinklers 10 a.m. – 6 p.m. |
| Hand watering & drip | Permitted any day |
Westminster’s 10 a.m. – 6 p.m. sprinkler ban is a permanent year-round ordinance, not a drought-specific rule. It applies from May through September every year regardless of drought stage. The drought watch adds the voluntary 3 days per week guidance on top of the existing rules. Westminster residents should already be programmed for early-morning or evening watering — the new piece is reducing the number of days.
What’s Restricted Beyond Lawn Watering
Beyond the voluntary watering reductions, Westminster’s parks and recreation department has voluntarily reduced irrigation on public spaces by 25% to set an example for residents. The city has also suspended all new turfgrass permits for commercial landscaping projects until the drought watch is lifted. Hand watering of trees, shrubs, vegetable gardens, and flower beds remains permitted any day. Westminster offers free xeriscape design consultations through the city’s sustainability office — a useful resource for residents considering long-term lawn alternatives.
Fines and Enforcement
There are no fines under the current voluntary Drought Watch — only requests. The year-round 10 a.m. – 6 p.m. sprinkler blackout (May through September) is enforceable independently of the drought watch — violating that rule can result in a citation regardless of drought stage. If Westminster moves to mandatory Stage 1 in summer 2026, the city’s ordinance permits enforcement through warnings, fines, and ultimately water service restrictions for repeat violators.
HOA Protection in Westminster
Colorado law (HB 21-1229) prohibits HOAs from requiring water-intensive landscaping, mandating cool-season turf, or penalizing homeowners for xeriscaping or drought-tolerant landscaping. The statute goes further than most US states by actively protecting homeowners who convert their lawns to drought-tolerant alternatives, even outside of declared drought periods. Combined with the City of Denver's public statement that brown lawns are expected during active restrictions, any HOA fine threatened against a brown lawn caused by following local restrictions is on weak legal ground. Keep a copy of your utility's restriction notice and the relevant city ordinance to share with your HOA board if a violation notice arrives.
Lawn Survival Guide for Westminster
Westminster’s residential lawns are predominantly Kentucky Bluegrass with some Tall Fescue. Brown KBG under voluntary 3-day watering is dormant, not dead. Use the tug test to confirm. Westminster’s Standley Lake area soil is especially alkaline, which causes iron chlorosis in turf and is worsened by drought stress — a chelated iron supplement helps, but should be applied to actively growing grass, not dormant turf.
- Voluntary 3 days per week is the current Westminster guidance — follow it now to ease pressure for mandatory escalation.
- Year-round 10 a.m. – 6 p.m. blackout still applies — program controllers for early morning or evening only.
- Westminster offers free xeriscape design consultations — schedule one through the city’s sustainability office.
- Standley Lake area soil is alkaline — iron chlorosis is common; apply chelated iron only to actively growing grass.
- Mow at 3 to 3.5 inches — taller grass shades soil and reduces evaporation under any watering schedule.
- Hand-water mature trees and shrubs any day — they are exempt from the voluntary guidance.
Will Restrictions Get Worse?
Westminster’s drought response plan has multiple stages above the current Drought Watch. If voluntary targets are not met by mid-summer, the city is expected to escalate to mandatory Stage 1 — 2 days per week with enforced fines. Boulder kept a similar Drought Watch position on May 1 with an early-June re-evaluation point, and Westminster water managers are watching the same conditions. With Colorado snowpack at 42% of normal, the path from voluntary to mandatory is short. Westminster residents who voluntarily cut their watering now both help avoid mandatory restrictions and build cushion for hotter months later.
