Start with your covenants
Read your declaration and design guidelines first. Look for the architectural review process, who reviews requests, which forms they use and whether turf, hardscape or landscape changes are named. Can't find them? Ask the HOA or management company for current copies. Then check what type of home you own, because that decides how much state law helps you.
What state law protects
SB23-178 says HOA rules cannot prohibit xeriscape, drought-tolerant landscaping or nonvegetative turf grass, and cannot prohibit nonvegetative turf in the backyard. It covers single-family detached homes only. In a townhome, attached home or condo, your covenants and board decide.
The bill says "nonvegetative turf grass," not "artificial." If your HOA argues the point, talk to an attorney.
What your HOA can still control
The law does not end architectural review. HOAs can still set design and appearance rules. Expect questions about color, pile height, edging and how the turf meets the fence or a neighbor's lot. For the front yard, an HOA must preapprove at least three designs and cannot unreasonably require hardscape on more than 20% of the landscaping area. Ask whether your HOA keeps a front-yard design list and whether turf fits one.
What to submit
A complete package gets a faster yes. Include:
- A site plan or sketch showing the area, its size and its boundaries.
- Photos of the existing yard.
- A physical turf sample, so reviewers can see color and texture.
- Manufacturer product specs and PFAS documentation. See the PFAS-free turf guide.
- Edge and border details such as pavers, metal edging or planter beds.
- Your installer's name and a written description of the base and drainage.
We can supply product and layout details for your request. Tell us you have an HOA when you ask for an estimate.
If your HOA says no
Ask for the specific rule in writing. If the denial concerns the backyard of a single-family detached home, point to SB23-178. The law gives owners a path. You notify the HOA, the HOA has 45 days to cure, and after that you can sue for up to $500 or actual damages.
That is a legal process, so talk to an attorney before you start it. A calm conversation or a revised design often works first.
Timing
Review periods differ from one association to the next. Ask your HOA how long it takes before you schedule work. Don't start until you have the approval in writing.
Other rules still apply
HOA approval is separate from city rules and the state PFAS install rule. Thornton, for example, requires a permit for turf on detached homes. Read Colorado turf rules for HOAs, cities and the state and call your city.
Common questions
Do I need HOA approval before installing turf?
Check your covenants. Even where state law protects backyard turf, HOAs can run architectural review for design details. Get approval in writing before work starts.
Does the HOA law cover condos and townhomes?
No. SB23-178 applies to single-family detached homes only.
What if my HOA denies turf in my backyard?
Ask for the rule in writing and talk to an attorney. SB23-178 lets an owner give notice, allow 45 days to cure and then sue for up to $500 or actual damages.
