Castle Rock's municipal code limits grass and weed height to 12 inches or less year-round, serving fire-prevention and nuisance-control purposes. Unincorporated owners must additionally manage noxious weeds under Colorado's Noxious Weed Act.
The Town of Castle Rock requires all properties to be maintained clear of overgrown vegetation. Grass and weeds may not exceed 12 inches in height at any time of year, a limit the Town describes as serving fire prevention rather than only noxious-weed control. Enforcement runs through Code Compliance, which mails reminder letters before escalating. In unincorporated Douglas County, there is no single county turf-height number, but owners must control state-listed noxious weeds under the Colorado Noxious Weed Act (C.R.S. Title 35, Article 5.5), and HOAs such as those in Highlands Ranch typically impose their own mowing standards.
Failure to comply with Castle Rock's height limit can result in code-enforcement action and Town-performed abatement billed to the owner.
