Fountain, CO Landscaping Rules: Weed Ordinances (2026)

030 makes it unlawful for an owner, lessee or occupant of any lot in the city, occupied or not, to let weeds grow on the property, on the abutting alley out to its midline, or along the sidewalk, street or parking strip bordering the lot. 020 pins down what counts: any unsightly, useless or troublesome herbaceous plant that grows without cultivation, is not planted for landscaping, slope stabilization, drainage control or food production, and reaches at least nine inches tall, including anything the state has declared a noxious weed under the Colorado Noxious Weed Act.

030(A)(2) states the height limit directly: grasses or other herbaceous plants cannot grow over nine inches in height unless grown for landscaping, slope stabilization, drainage control or food production. A separate rule in subsection B targets larger properties: on any lot over one acre, weeds cannot exceed nine inches within 30 feet of a dedicated street or public right-of-way, or within 30 feet of any neighboring lot of one acre or less, so a big parcel cannot let its weeds spill a buffer zone into a smaller neighbor's yard or the street. 060.
