Summary
Ramsey County (Minnesota) sets no residential grass-height limit for its cities: that is municipal (St. Paul requires grass/weeds under eight inches). Statewide, Minn. Stat. §18.78 makes every landowner responsible for controlling noxious weeds as ordered by an inspector.
A person owning land, a person occupying land, or a person responsible for the maintenance of public land must manage all noxious weeds, according to the noxious weed categories under section 18.771, on the land at a time and in a manner ordered by an inspector or county-designated employee.
Full Breakdown
Grass-height limits are a city rule in Ramsey County. St. Paul Legislative Code (Chapter 45) requires property owners and occupants to keep grass and weeds less than eight inches high; taller vegetation or seeded weeds must be cut. Suburbs set their own thresholds (commonly eight inches). Separately, statewide law imposes a noxious-weed duty on all Minnesota land regardless of city: Minn. Stat. §18.78 requires a landowner or occupant to manage noxious weeds as ordered by an inspector or county-designated employee. Ramsey County's Agricultural Inspector administers the state noxious-weed law, but the everyday tall-grass mowing rule is your city's.
Violations & Fines
City abatement (St. Paul): the city mows overgrown lots and assesses the cost, plus service fees, to the property. State noxious-weed noncompliance allows county-ordered control at owner expense.
