Colorado law protects a homeowner's right to install water-wise and native landscaping. Under SB23-178, HOAs cannot ban drought-tolerant xeriscape or native plants, and Castle Rock Water actively encourages low-water native landscaping.
Colorado Senate Bill 23-178 requires HOAs to allow water-wise, drought-tolerant, and native landscaping, limiting covenants that force high-water turf. There is no state or Castle Rock rule requiring native plants, but the Town's Castle Rock Water utility strongly promotes native and low-water plantings as a conservation strategy and lists them among approved noxious-weed management methods (native landscaping). Residents replacing thirsty lawn with native or xeriscape plantings still must control noxious weeds and keep growth trimmed under 12 inches. Check Castle Rock Water for rebate and plant-selection resources.
No penalty for choosing native plants; an HOA that unlawfully bans water-wise landscaping violates SB23-178. Overgrown or noxious plants remain enforceable under Town code.
