No. Ending single-family zoning means allowing a wider variety of housing types than just detached homes.
For example, Ann Arbor’s new Comprehensive Land Use Plan includes a Residential category that covers many areas that are currently zoned for only single-family housing. The plan suggests that duplexes, triplexes, small apartment buildings, and neighborhood stores should also be allowed in these areas along with single-family homes.
