Can Your Colorado HOA Force You to Keep a Grass Lawn?

Colorado HOAs have a reputation for being strict. But since 2023, the state has had one of the clearest protections in the country for homeowners who want to replace turf with water-wise landscaping.

The short version: if your landscaping conserves water, your HOA can't ban it simply because it isn't grass. Here is what the law actually says, what your HOA can still require, and how to handle pushback if it comes.

SB 23-178: Colorado's Xeriscape Homeowner Protection Law

Senate Bill 23-178, signed into law in 2023, amended the Colorado Common Interest Ownership Act (C.R.S. §38-33.3-106.5) to prohibit HOAs from banning xeriscape. The core provision reads, roughly:

In plain language: if you want to replace your lawn with drought-tolerant plants, mulch, gravel, or native groundcovers, your HOA cannot say no on the grounds that you aren't maintaining turf grass. Colorado is classified as a drought-prone state, which makes this protection apply statewide.

The law also applies even if your CC&Rs were written before 2023. State statute overrides any HOA governing document that conflicts with it. You don't need to petition for a CC&R amendment to have these rights.

Colorado's broader water-wise landscaping history

SB 23-178 built on earlier law. Colorado had already prohibited HOAs from banning xeriscape under C.R.S. §38-33.3-106.5 since 2015, but that version left room for HOAs to effectively block conversions through appearance and maintenance objections. The 2023 update tightened the language to close those gaps.

The legislature also recognized that Colorado's water situation is structurally different from most states. With the Colorado River system under prolonged stress and Front Range cities regularly asking residents to cut outdoor water use, a law that lets HOAs mandate thirsty turf runs counter to state water policy.

What your HOA can still require

The law doesn't give you a pass to do whatever you want. Your HOA can still enforce:

• General maintenance standards (no dead plants piling up, no visible weeds taking over)
• Clean borders and edging along sidewalks, driveways, and fences
• Plant height limits near sight lines or pedestrian paths
• Pre-approval requirements for significant landscaping changes
• Rules about structures like raised beds, garden art, or trellises
• Setback requirements from property lines

The standard your HOA can hold you to is: does the yard look maintained and intentional? They cannot hold you to: does it have turf grass?

What your HOA cannot require

• Turf grass specifically, if your alternative qualifies as xeriscape
• A minimum percentage of lawn coverage
• Removal of drought-tolerant or native plants that are visibly maintained
• Watering schedules that would require maintaining a traditional lawn

In the Denver metro, this matters practically. Denver Water has been offering turf removal rebates and encouraging xeriscape for years. Your HOA pushing back on a conversion puts them at odds with the city utility's own programs.

Common pushback tactics (and how to respond)

When to talk to a lawyer

Most situations resolve with good documentation and a calm conversation. Consider legal advice if:

• Your HOA is fining you after you've cited SB 23-178 in writing
• They're threatening to place a lien on your property
• You've submitted a plan and made visible maintenance improvements, but they're still rejecting it without a specific CC&R citation

A Colorado real estate attorney who handles HOA disputes can usually resolve this with a single letter. It doesn't need to be an extended fight.

Practical next steps

If you're planning a lawn conversion in an HOA neighborhood in Colorado:

1. Get a copy of your CC&Rs and read the landscaping section. Know exactly what it says before you start.
2. Check your HOA's approval process. Most have an architectural review committee or a variance request form.
3. Put together a plan with a plant list, a rough layout, and a short note on how you'll maintain it. This separates "I stopped mowing" from "I'm converting to xeriscape."
4. Submit before you start. Proactive submission is the single best way to avoid disputes.
5. Check for Colorado rebate programs that can offset conversion costs. Denver Water, Fort Collins Utilities, and other Front Range utilities offer turf removal incentives.

What counts as xeriscape in Colorado?

Colorado law doesn't define xeriscape narrowly. It generally means landscaping that is drought-tolerant and uses significantly less water than traditional turf grass. Native plants, ornamental grasses, groundcovers, mulch, and gravel-based designs all qualify. The key is that the yard uses low water input plants or materials, not that it matches a specific plant list.

Can a Colorado HOA require me to water during a drought restriction?

No. Municipal water restrictions take precedence over HOA rules. Colorado cities and counties regularly issue watering restrictions during drought conditions, and HOAs cannot fine you for complying with them. If your HOA sends a notice about a brown lawn during an active watering restriction, document the city's current restriction in writing for any dispute response.

Does SB 23-178 apply to all HOAs in Colorado?

It applies to HOAs governed by the Colorado Common Interest Ownership Act, which covers most community associations in the state including planned communities, condominiums, and townhome associations. If your HOA was established before CCIOA went into effect in 1992, the rules around applicability are more complex and worth checking with an attorney.

What does "xeriscape" have to look like to be protected?

The law protects xeriscape as a practice, not a specific visual style. Your HOA can still require that the result looks maintained. That means: clean edges, no dead plant material left in piles, visible intentionality in layout. A mulched bed with drought-tolerant natives and a clean border meets the standard. A patch of dead grass replaced by nothing does not.
