Minneapolis homeowners could soon have more flexibility to build bigger, split properties, and add energy-efficient features under a wide-ranging overhaul of zoning rules covering homes with one, two, or three units. The city’s proposed amendment summary touches nearly every corner of residential development. Key changes include raising the maximum floor area ratio for three-unit homes in Interior 1 and Interior 2 districts, allowing duplex owners to split their property without a formal hearing, and removing the rule that lets garages extend more than five feet in front of a house. Bigger three-unit homes in Interior 1 and Interior 2 districts One of the most significant shifts affects triplexes in Interior 1 and Interior 2 Built Form Overlay Districts. The maximum floor area ratio for three-unit homes in those districts would rise from 0.5 to 0.6—a change the city describes as making it possible to build units at a “more practical size.”
In plain terms, the change allows more total floor area per triplex, which could make three-unit projects more financially viable to build. Splitting a duplex just got easier Owners of side-by-side two-unit homes would be allowed to split their property along the shared wall into two separate parcels without triggering a formal hearing.
Right now, that kind of subdivision requires a hearing process that adds time and cost. Removing that barrier could make it easier for duplex owners to sell one half, refinance, or pass property to family members.
Garages, setbacks, and side doors The proposal would eliminate the rule that currently allows garages to extend more than five feet in front of the main house. Interior side yard setbacks would generally increase, but the city is adding exceptions for small lots, for situations where a side door faces a nonresidential property, and for doors positioned close to the front or rear wall of a home. Detached accessory dwelling units would also be allowed to have separate street-facing entrances—something the existing rules prohibit. New ways to earn design points Minneapolis already uses a point-based design menu that builders must satisfy during site plan review. The proposal adds several new ways to earn those points. New qualifying options include building an ADU at the same time as a new primary home, achieving a HERS energy efficiency score of 45 or lower, and installing solar panels that produce at least half the home’s annual electricity. Metal siding that isn’t aluminum would also become an eligible exterior material.
Rules around open front porches would be clarified, including a note that columns don’t count toward the minimum porch area. It’s worth noting that several items in the proposal are clarifications to existing rules rather than outright changes—including how basements are defined, how floor-area calculations work, and what qualifies as a porch. Those updates don’t alter what’s allowed so much as spell out what was already intended. What’s next The proposal is still at the summary stage.
