Full Breakdown

Sec. 41.08(b) puts the duty on the owner to maintain improved property so that grass or weeds never exceed 12 inches in length. Improved property is defined in Sec. 41.06 as any lot, tract or parcel with a structure or improvement on it. Sec. 41.08(g) extends the duty into the right-of-way: you maintain the strip from the edge of the pavement to your property line, which includes properly mowing the grassed area, clearing grass, weeds, sand, silt and debris from the driveway culvert, and keeping any swale flowliner clear. Let it go far enough and Sec. 40.05 treats untended grass over two feet on improved property as a public nuisance the city can abate.

Violations & Fines

Code compliance issues a notice first. Untended grass over two feet becomes a nuisance the city may abate under Sec. 40.20, with the cost assessed against the property, and the special magistrate may fine up to $1,000 per day.
