Summary
Ramsey County sets no lot-coverage limit for city land; your city does under Minn. Stat. §462.357. In St. Paul's R1–R4 districts, principal buildings may cover no more than 35% of the lot.
In R1–R4 residential districts, principal buildings shall not cover more than thirty-five (35) percent of any zoning lot.
Full Breakdown
Maximum lot coverage on incorporated land is set by your city, not Ramsey County, under Minn. Stat. §462.357, which authorizes a municipality to regulate the percentage of a lot that may be occupied. The county enforces no countywide coverage cap. In St. Paul, principal buildings in the R1 through R4 residential districts shall not cover more than 35 percent of any zoning lot. Suburbs set their own coverage and impervious-surface limits. Because accessory buildings and impervious surfaces may count differently by city, confirm how your municipality measures coverage before adding on.
Violations & Fines
Exceeding the coverage limit can block permit approval; the project must be resized or granted a variance by the city.
