# Colorado SB 23-178 (2023A) — Water-wise Landscaping In Homeowners' Association Communities

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.
