Douglas County sets no countywide grass-height rule for private lots; your city or metro district does. In Castle Rock, the Municipal Code caps weed and grass growth at 12 inches or less for fire prevention, and the property owner must manage it.
Colorado counties zone unincorporated land but rarely set turf-height limits; in unincorporated Highlands Ranch, HOA covenants and the metro district govern lawn upkeep. Incorporated towns set their own limits. Castle Rock's code (Chapter 8.12) limits weed and grass height to 12 inches, citing fire prevention, and makes the property owner responsible. Tall dead grass is treated as a fire hazard and nuisance. Abatement is by mowing or hand-trimming. Parker and Lone Tree run similar property-maintenance programs. Check your specific town or HOA rather than assuming a single county standard.
Castle Rock issues reminder letters, then Code Enforcement action if uncorrected; the Town may abate and bill the owner.
