Full Breakdown
CBMC 1.97.030's nuisance definition sets the citywide threshold: weeds, vines, bushes, volunteer trees under three inches in diameter, grass and other growths over eighteen inches, and any noxious weed defined by Iowa Code at any height, are a nuisance on any lot or parcel within the city limits. CBMC 4.19.010 turns that definition into an owner's duty, requiring every owner or occupant of a lot or parcel to immediately cut or otherwise destroy qualifying growth, and if they don't, the administrative authority does it for them.
Before the city acts, CBMC 4.19.020 requires at least seven days' notice, given by newspaper publication, a dated placard posted on the property, or regular mail to the owner of record. If the growth isn't cut within that window, the city can abate it and bill the property owner under CBMC 4.19.030, with fees delinquent after ten days and collectible as a property tax assessment through the county auditor under Iowa Code Section 364.12. CBMC 4.19.060 separately makes it unlawful for any owner or occupant to permit a weed nuisance to exist on the lot or on the abutting right-of-way out to the curb line and alley center required by CBMC 4.19.040.
Violation carries the penalty in CBMC 4.19.070: a misdemeanor under CBMC 8.02.020, or, at the city attorney's discretion, a municipal infraction under CBMC 1.95 or enforcement under CBMC 8.56, with every day of continuing violation a separate offense.
Violations & Fines
Letting weeds, grass, vines, bushes or volunteer trees under three inches in diameter exceed eighteen inches, or letting any Iowa Code noxious weed grow at all, is unlawful under CBMC 4.19.060 once the seven-day cut notice in CBMC 4.19.020 expires uncured. The city can then abate the growth and bill the owner under CBMC 4.19.030, and CBMC 4.19.070 makes the violation a misdemeanor or municipal infraction, with each day counted separately.
