Brighton CO Water Restrictions 2026
Published: Updated:
Adams / Weld County· Colorado
Brighton City Council voted unanimously 9-0 on April 7, 2026 to approve Stage 1 drought restrictions — effective immediately — as the city responds to record-low snowpack and the driest Colorado spring in more than two decades. The order requires a 20% reduction in citywide water use, sets a two-day-per-week watering schedule based on address, and bans new sod installations larger than 200 square feet. Brighton joins Denver, Aurora, Broomfield, and several other Front Range communities now operating under formal Stage 1 rules. This page covers Brighton's specific schedule, exemptions, fines, and what to expect if the city escalates to Stage 2 or Stage 3 later in the summer.
Current Status
Brighton is now under Stage 1 of its drought response plan, the second of three escalating tiers. The City Council’s unanimous April 7 vote means the rules apply to every Brighton water customer immediately, with no grace period. The headline target is a citywide reduction in water use of 20%. To achieve that, automatic and manual sprinkler watering is limited to two specific days per week per address, and the daytime blackout from 10 a.m. to 6 p.m. is now mandatory rather than advisory. Hand watering of trees, shrubs, and flowers with a can or hose is exempt and actively encouraged, since Brighton’s water managers want residents to keep mature trees alive even as turf goes dormant.
Watering Schedule by Address
Brighton uses an address-based schedule with three groups. Look at the last digit of your house number to find your assigned days, then program your sprinkler controller before your next watering window.
| Group | Watering Days |
|---|---|
| EVEN addresses (0, 2, 4, 6, 8) | Tuesday & Friday |
| ODD addresses (1, 3, 5, 7, 9) | Wednesday & Saturday |
| Unassigned addresses & tracts | Monday & Friday |
Watering is allowed only outside the 10 a.m. – 6 p.m. blackout window on your assigned days. Best practice is to water before 8 a.m. when wind is minimal and evaporation is lowest. If you have an irrigation controller with rain sensors, ensure it is functioning — watering during or within 24 hours of rainfall is also a violation under Stage 1.
What’s Restricted Beyond Lawn Watering
Brighton’s Stage 1 ordinance restricts more than just sprinkler schedules. New sod installations or lawn replacements larger than 200 square feet are prohibited for the duration of the order — small repair patches are still permitted but full-yard turf installs are not. Water that pools in gutters, runs into streets, or visibly wastes off your property is a citable violation, regardless of which day or hour it happens. Hand watering of trees, shrubs, vegetable gardens, and flower beds with a watering can or shut-off-equipped hose is exempt and is actively encouraged — the city wants mature trees and food gardens preserved through the drought even as ornamental turf is allowed to go dormant.
Fines and Enforcement
Brighton uses an escalating fine structure for non-compliance, beginning with a written warning for first offenses and increasing for repeat violations. Enforcement is handled by City of Brighton water staff, who respond to complaints and conduct visual patrols of irrigation systems running outside permitted hours. The city has indicated that the focus during the early weeks of Stage 1 is education rather than punishment — but customers who continue to ignore the schedule after a warning will face escalating penalties that can ultimately include water service surcharges.
HOA Protection in Brighton
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 Brighton
Brighton’s dominant lawn grass is Kentucky Bluegrass (KBG), which becomes dormant when summer temperatures climb past 85°F. Brown KBG under Stage 1 restrictions is dormant, not dead — the crown remains alive and the lawn will recover when restrictions lift. Use the tug test to confirm. Survival watering for dormant KBG is just ½ inch every 14 days, which fits easily inside the two-day-per-week schedule.
- Even addresses water Tuesday/Friday; odd addresses water Wednesday/Saturday — program your controller before your next allowed window.
- Hand-water mature trees and shrubs any day — they are exempt and worth far more than turf if drought worsens.
- Mow at 3 to 3.5 inches — taller grass shades the soil and reduces evaporation by 30 to 40%.
- Skip fertilizer entirely until restrictions lift — nitrogen on a drought-stressed lawn forces growth the plant cannot support.
- Consider Buffalo Grass or Blue Grama for any new planting — both natives need a quarter of the water KBG demands.
Will Restrictions Get Worse?
Brighton’s drought response plan has two tiers above the current Stage 1: Stage 2 cuts watering to one day per week and reduces park irrigation by 50%; Stage 3 is a full emergency that bans all outdoor watering. With South Platte Basin snowpack at 42% of normal — the worst on record — city officials have explicitly said both higher stages remain on the table for summer 2026. The trigger for escalation is reservoir storage relative to expected demand. Brighton residents should plan for the possibility of Stage 2 by July if Front Range conditions do not improve.
