Summary
Minneapolis caps new house size through floor area ratio limits in its Built Form Overlay Districts, as low as a 0.5 multiplier of lot area in Interior 1 neighborhoods, to keep additions and rebuilds from overwhelming smaller lots.
540.110. - Maximum floor area ratio. (a) In general. The maximum floor area ratio requirements of principal structures, except cluster developments, shall be as set forth within Table 540-2, Maximum Floor Area Ratio. ... Interior 1 | UN, RM | All uses except Institutional and Civic Uses: 0.5

Full Breakdown
Minneapolis Code of Ordinances § 540.110 sets a maximum floor area ratio for every Built Form Overlay District, and Table 540-2 caps most uses in the Interior 1 overlay at a 0.5 multiplier of lot area: the district applied to typical single-family blocks. A one- to three-unit home on a 5,000-square-foot lot is capped near 2,500 square feet of gross floor area. Section 540.120(b) offsets this on undersized lots, guaranteeing 2,500 square feet even where the multiplier would otherwise allow less. The zoning administrator reviews building permits against these limits before construction can proceed.
Violations & Fines
Building permit applications exceeding the district's floor area ratio are rejected by the zoning administrator; construction that violates the built form standards is subject to the city's standard zoning enforcement and correction process.
