St. Louis County, MN Building Setbacks & Zoning: Setback Rules (2026)

2 Structural Setback Standards table sets the county's default property line setback at 10 feet for a principal structure and 5 feet for an accessory structure, figures that apply outside the more restrictive shoreland and river-corridor tables found later in Article III. 5 feet for both structure classes. Road setbacks are measured from the road centerline rather than the right-of-way edge: 110 feet on an Arterial road, 85 feet on a Collector, and 48 feet on a Local road, with no separate right-of-way-based figure listed.

2 tables and Article V land use districts, and any structure that cannot meet them, short of a narrow 3-foot roofline overhang allowance that cannot interfere with a neighbor's solar access or drainage, needs a variance from the St. Louis County Board of Adjustment before it can be built. 4 and can run from 75 feet up to 300 feet depending on the water body, superseding the generic 75-foot figure where they apply.
