Minneapolis did not change the zoning sufficiently -- the new duplexes and triplexes nearly have to fit into the same footprint as the equivalent single family home. So you can have one big SFH or two half-sized duplexes, etc.

For a single family home, the footprint can't take up more than 50% of the lot. For a duplex, the footprint can't take up more than 60% of the lot. Duplex and triplex projects could be made much more compelling by loosening these restrictions.
