Arapahoe County, CO Landscaping Rules: Native Plants (2026)

Under current law, a unit owners' association (association) of a common interest community may not prohibit the use of xeriscape, nonvegetative turf grass, or drought-tolerant vegetative landscapes to provide ground covering to property for which a unit owner is responsible. There is, however, an exception authorizing an association to adopt and enforce design or aesthetic guidelines or rules that apply to nonvegetative turf grass and drought-tolerant vegetative landscapes or to regulate the type, number, and placement of drought-tolerant plantings and hardscapes that may be installed on a unit owner's property, on a limited common element, or on other property for which the unit owner is responsible. The act states that an association's guidelines or rules must: Not prohibit the use of nonvegetative turf grass in the backyard of a unit owner's property; Not unreasonably require the use of hardscape on more than 20% of the landscaping area of a unit owner's property; Allow a unit owner an option that consists of at least 80% drought-tolerant plantings; and Not prohibit vegetable gardens in the front, back, or side yard of a unit owner's property. The act requires an association to develop at least 3 garden designs that are preapproved by the association for installation in front yards within the common interest community. To receive preapproval, a garden design must adhere to the principles of water-wise landscaping or be part of a water conservation program operated by a local water provider. A unit owner who is affected by an association's violation of the act's requirements may, after providing the association notice of and a 45-day period to cure the violation, bring a civil action to restrain further violation and to recover up to $500 or actual damages, whichever is greater.
