Summary
Castle Rock caps weed and grass height at 12 inches. Under Municipal Code 8.12.030, properties may not be overgrown with grass or weeds exceeding 12 inches at any time during the year. Owners must also control state-listed noxious weeds under the Colorado Noxious Weed Act.
Properties may not be overgrown with grass or weeds exceeding 12 inches in height.
Full Breakdown
Chapter 8.12 of the Municipal Code (Health and Safety) sets the standard: "Properties may not be overgrown with grass or weeds exceeding 12 inches in height." The Town notes the limit "serves a fire prevention purpose rather than a noxious weed control function." Separately, residents are required by both Town code and CRS Title 35 (the Colorado Noxious Weed Act, C.R.S. 35-5.5) to control noxious weeds on their property. Abatement may be done by hand trimming or mowing. It is the property owner's responsibility to manage weed height. Report violations at CRgov.com/ReportAConcern, issue type 17.
Violations & Fines
The Town sends reminder letters to owners in violation; continued non-compliance results in Code Enforcement action and possible Town abatement at the owner's expense.
