🏠 HOA Rules During Restrictions

Colorado law (HB 21-1229) prohibits HOAs from requiring cool-season turf or penalizing homeowners for drought-tolerant landscaping. Commerce City HOAs cannot fine residents for following SACWSD's delayed start or 3-day schedule.

If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the South Adams County Water and Sanitation District's current restriction order. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your county’s code enforcement division for assistance.

Why These Restrictions Exist

Commerce City is served primarily by the South Adams County Water and Sanitation District (SACWSD), which is independent of Denver Water and draws from a mix of South Platte alluvium wells and surface water rights. For 2026, SACWSD pushed the irrigation season start back to May 4 in response to record-low South Platte snowpack and to give the system additional recovery time. Residents north of 96th Avenue may be on different supply zones, check sacwsd.org with your address to confirm.

Rainfall Deficit: South Platte Basin snowpack at record low. SACWSD delayed irrigation start to May 4, 2026.

This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Commerce City area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.

How to Keep Your Lawn Alive During Commerce City Water Restrictions

7 tips tailored for Commerce City homeowners during Delayed Irrigation Start - May 4, 2026 restrictions.

Do NOT turn on automatic sprinklers before May 4, 2026, SACWSD's district-wide delayed start.

Odd: Tue/Thu/Sat; Even: Wed/Fri/Sun. No watering Monday district-wide.

Hand watering with a shut-off nozzle is permitted before May 4 for new plantings or stressed turf.

Kentucky Bluegrass dominates older Commerce City lawns, going dormant for 2–3 weeks before May 4 will not kill it.

Commerce City's heavy clay soils benefit from cycle-and-soak (10 min on, 30 min off, 10 min on) to prevent runoff.

Check sacwsd.org for your specific service zone, pressure zones north of 96th may have different rules.

SACWSD offers free indoor and outdoor water audits, call 303-288-2646 to schedule.
