What does Colorado’s turf law ban now?
The rule comes from SB24-005, as amended by HB25-1113. Since January 1, 2026, Colorado cities, towns and special and metro districts may not install or allow nonfunctional artificial turf as part of new development or redevelopment on the property types the state law covers:
- commercial, institutional and industrial property
- HOA common property
- street rights-of-way, parking lots, medians and transportation corridors
Single-family lots aren’t on that list. From January 1, 2028, the ban also covers common areas, such as entryways and parks, of multifamily properties with more than 12 dwelling units.
Two definitions do most of the work:
- Redevelopment is a construction project that needs a building or landscaping permit, plan check or design review and disturbs more than 50% of the landscape area.
- Existing turf. The law does not stop a local government from letting turf installed before January 1, 2026 be maintained. Whether a full replacement counts as maintenance hasn’t been tested, so ask the town before you plan one.
What still counts as functional turf?
Functional artificial turf stays allowed. Colorado’s 2025 amendment defines it as artificial turf located in a recreational use area or other space regularly used for civic, community or recreational purposes, which may include:
- a playground
- a sports field
- a picnic ground
- an amphitheater
- a portion of a park
- the playing area of a golf course, such as a driving range, chipping and putting green, tee box, green, fairway and rough
On new development and redevelopment, that’s the line a board or a developer is working with: turf that gets played on, gathered on or putted on can go in, and turf that’s only there to look green, in an entry bed or down a median, can’t. The drawing at the top of this page maps it on one site.
What do the town codes say on top of the state law?
State law sets the floor. These town codes in the corridor say more:
| Town | What its code says |
|---|---|
| Windsor | Bars artificial turf from any landscape plan for new development or major redevelopment, allowing only functional artificial turf by the Director’s exception. |
| Fort Collins | Bars artificial turf from development landscape plans; development on existing single- and two-unit home lots is exempt from that section. |
| Evans | Artificial turf is not acceptable for public or common areas. |
| Greeley | Allows artificial turf as ground cover only in areas not visible from public rights-of-way and streets. |
| Dacono | Artificial plants and synthetic turf can’t be used to meet its landscaping requirements. |
| Longmont | Bans nonfunctional artificial turf in new development and redevelopment on multifamily, commercial, industrial, institutional and common-interest property and in rights-of-way, medians and transportation corridors. |
| Eaton | Since January 1, 2026, bars nonfunctional artificial turf in new development and redevelopment on rights-of-way, commercial, institutional and industrial property, HOA common property and multifamily properties with more than 12 units. |
| Milliken | Bars nonfunctional artificial turf in new development and redevelopment on commercial, institutional, industrial, HOA common and right-of-way property. |
| Wellington | Doesn’t permit nonfunctional artificial turf in new development or redevelopment; turf installed before January 1, 2026 may be maintained. |
| Loveland | Updated its development code in March 2026 to apply the state nonfunctional-turf law; the city says that law does not apply to single-family lots or private lots in duplex, condo and townhome developments. |
Before a board votes, read the town’s current code and your HOA or district’s own rules. The town-by-town turf rules keep the sources and dates.
What decides whether a common-area field lasts?
Common-area and sports turf takes more traffic than any backyard, and it takes it in the same places: the goal mouth, the bottom of the slide, the path in from the parking lot.
- Drainage at scale. A field sheds a lot of water. The Colorado Geological Survey says the state’s expansive clays can swell up to 20% by volume when wet, and water that ponds under turf is water that moves the ground.
- The right surface for the use. A sports field, a playground and a putting green are three different builds, with different turf, infill and padding.
- Documents for the board. Spec sheets, and PFAS documentation: since January 1, 2026, Colorado law bars anyone from installing artificial turf that contains intentionally added PFAS chemicals.
- A maintenance plan. Brushing, infill top-ups and debris removal on a schedule, with someone named to do it.
- Who pays. Colorado’s state turf-replacement grant money may not be used to replace lawn with artificial turf. The Colorado Water Conservation Board’s grant last closed on February 28, 2025, and HOAs and businesses were never eligible to apply for it directly. More in the rebate guide.
