Denver enforces weed abatement under DRMC §24-101, requiring property owners to keep grass and weeds below 10 inches. The Colorado Noxious Weed Act (CRS §35-5.5-101) adds state-level obligations on noxious species. DDPHE handles complaints and abatement.
DRMC §24-101 et seq. declares weeds and grass exceeding 10 inches in height a public nuisance and requires property owners to maintain lots. Denver Department of Public Health and Environment (DDPHE) inspects complaints (filed via Denver 311) and issues a Notice of Violation with a 10-day compliance window. If the owner fails to abate, Denver Parks and Recreation or contracted crews mow the property, and DDPHE bills the owner including a 15% administrative fee; unpaid bills become liens. The Colorado Noxious Weed Act (CRS §35-5.5-101 through §35-5.5-120) establishes List A (eradicate), B (manage), and C species administered by the Denver Weed Management District and the Colorado Department of Agriculture. List A species include myrtle spurge and purple loosestrife and must be eradicated. Fire-danger during dry Front Range summers and Denver's urban-wildlife concerns (rat harborage in tall grass) drive enforcement intensity. Vacant lots receive automatic inspection during late spring.
10-day notice to abate. City mows and bills $200 to $1,000+ plus 15% admin fee and potential property lien. DRMC §24-101 municipal fine up to $999. State Noxious Weed Act violations: civil penalty up to $1,000 per day.
