Unincorporated Larimer County sets no maximum grass or weed height and does not require lawns to be mowed. Only Colorado-listed noxious weeds must be controlled by the property owner.
The county confirms it has no property-maintenance code and, given its agricultural character, no rule on how high weeds grow or whether a lawn is mowed. The one exception is noxious weeds: the Larimer County Weed District enforces the Colorado Noxious Weed Act on unincorporated land, so owners must manage listed species like Canada thistle or leafy spurge. Inside Fort Collins, city code caps grass and weeds at 6 inches on developed residential and commercial property and 12 inches on undeveloped land.
No county penalty for tall grass alone; noxious-weed non-compliance can lead to a written notice and county abatement charged back to the owner.
