Artificial lawns in the Denver Metro, placed where your HOA and city allow.

What your HOA can limit depends on the kind of home you own.

On a detached home, association guidelines must "not prohibit the use of nonvegetative turf grass in the backyard of a unit owner's property" (C.R.S. 38-33.3-106.5(1)(i.5)). The board still keeps its bona fide safety rules, its rules on fire buffers and defensible space, and its say over changes to existing grading and drainage. Out front, the statute has the board preapprove at least three water-wise garden designs. Those are plantings, not turf.

If your home shares one or more walls with another unit, a different subsection applies. The association "shall not prohibit" nonvegetative turf grass on property you're responsible for, but it can set design rules and "may restrict the installation of nonvegetative turf grass to rear yard locations only" (C.R.S. 38-33.3-106.5(1)(i)). The detached-home subsection says in terms that it does not apply to a condominium. In a condo, ask the association for its written turf rules before you plan anything.

SB23-178 set up this split between detached and attached homes. It was signed on 17 May 2023 and took effect on 7 August 2023 (Colorado session laws, chapter 207). FindLaw's copy of the statute, current as of 1 January 2025, carries the same wording, so cite the section when you ask your board for its position in writing. None of it binds your city: the covenant rule in C.R.S. 37-60-126(11) "does not supersede any subdivision regulation" of a municipality (C.R.S. 37-60-126). The Colorado HOA turf guide covers what to do if a board refuses anyway.

A back yard beside a street or park needs a check in two cities.

In Arvada, turf can be the main ground cover in a back or side yard only where it is "not in public view", and public view covers anything seen from streets, sidewalks, parks and trails. A putting green of up to 400 square feet is the exception (Arvada § 4-6-7-2). The rule reaches a change to an existing landscape, unless your subdivision was first built with nine or fewer single-family or duplex lots (Arvada § 4-6-3-1).

In Westminster, the regulations allow turf in single-family detached and duplex "yard areas not adjacent to a street, or public or private park or open space" (Westminster Landscape Regulations 2004). So in both cities, check a corner lot, or a yard that backs onto a park, before you plan turf. Add sidewalks and trails in Arvada, and open space in Westminster.

The other cities treat the back yard differently. Thornton's rules say turf is "allowed with no limitations" in rear and enclosed side yards (Thornton Water rules dated 1 January 2026). Brighton lists artificial turf among the materials a back yard may have (Brighton § 8.02), while its water-wise rules ask for living ground cover on at least 50% of the landscape area (Brighton § 8.04). Northglenn applies its turf rules to existing single-family yards and bars turf on slopes greater than six percent (Northglenn Municipal Code).

Out front, most cities cap the share, and two keep a turf lawn off the street.

The step 2 rules leave no room for a turf lawn in a street-facing front yard in Arvada or Westminster. Westminster also wants 50% of a single-family front yard in vegetation (City of Westminster FAQ, April 2025).

Thornton caps turf at 25% of the landscape area in front and unenclosed side yards. You need a Minor Development Permit before installation, and living plants with the turf: one tree equivalent for the first 750 square feet, and half of one for each additional 250 square feet (Thornton Water).

Brighton limits turf to 20% of the frontage area of a detached house, duplex or row house (Brighton § 8.02). Its landscape standards apply to new development. They exempt improvements to a detached house or duplex that need no Site Improvement or Residential Design Review and aren't part of a larger subdivision plan, and improvements to existing development that don't increase building footprint or impervious surfaces by more than 10% (Brighton § 8.01). Ask Community Development which case your address is.

Lafayette wants live materials on at least 75% of the gross front yard, driveways excluded. The section is written for new development, but it also says a building permit application for an individual single-family home must comply with that front-yard rule (Lafayette § 26-19-5). Ask the Planning Division whether your project needs a permit that brings it in.

Aurora Water's drought page says residents may install artificial turf "subject to a 50% coverage maximum", in its answer on why it gives no rebate for converting a yard entirely to turf. It doesn't say what the 50% is measured against (Aurora Water). Get that answer from Aurora Planning in writing before you draw a front lawn.

Your water provider sets the rebate and the watering rules.

Budget the lawn without a rebate unless your provider confirms one in writing. Denver Water's lawn-removal discount needs a plan for a water-wise landscape, and "artificial turf is not allowed". A notice dated 28 March 2026 says its 2026 discounts have all been allocated (Denver Water). Thornton Water is the exception: its 2026 rebate pays toward turf that replaces high-water lawn on an existing lot. The water rebates guide covers Aurora, Erie, Highlands Ranch and the rest.

If you're weighing new sod instead, check establishment watering first. On 26 August 2026 Denver Water's board ended the lawn watering season, banning lawn watering and all spray irrigation after 30 September. Its watering rules also say establishment permits for new seed or sod "will not be available after Sept. 30 until further notice" (Denver Water). Aurora Water's drought page, read on 12 September 2026, lists Stage 1 rules that say "No new cool-weather turf can be installed" (Aurora Water).

Turf arrives green and needs no establishment watering or assigned days, though a rinse still takes some water. Drought stages change, so confirm the current rules with the provider named on your bill before you choose between sod and turf.
