Summary

Dakota County has no countywide lot-coverage limit. The maximum percentage of a lot that buildings and impervious surface may cover is set by each city's zoning district under Minn. Stat. 462.357.

These county ordinances apply to unincorporated areas of Dakota County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

A municipality may by ordinance regulate on the earth's surface, in the air space above the surface, and in subsurface areas, the location, height, width, bulk, type of foundation, number of stories, size of buildings and other structures, the percentage of lot which may be occupied, the size of yards and other open spaces.

Full Breakdown

Lot coverage, the share of a lot that structures and hard surfaces may occupy, is a municipal zoning standard in Dakota County. Minnesota Statute 462.357 expressly authorizes cities to regulate the percentage of a lot that may be occupied. Residential districts commonly limit building or impervious coverage (for example, around 25 to 35 percent), with tighter limits in shoreland areas to protect water quality. Exact percentages vary by city and district. In unincorporated townships and shoreland zones, the Dakota County Shoreland and Floodplain Management Ordinance imposes impervious-surface limits. Confirm your district's cap with your city planning department.

Violations & Fines

Exceeding the coverage limit results in permit denial or a required variance; over-coverage in shoreland areas may also violate county ordinance.

Frequently Asked Questions

What percentage of my lot can I build on?
It depends on your city's zoning district, often roughly 25 to 35 percent for residential lots. Check your city code, as coverage limits vary widely.
Do lot-coverage rules protect water quality?
Yes. Shoreland districts and the Dakota County Shoreland and Floodplain Ordinance impose stricter impervious-surface limits near lakes, rivers, and wetlands.
