In any place that has single-family zoning, it is illegal to construct multi-family housing. Many US cities are changing this. Proud to live in Minneapolis where this (and better) is now completely legal to build in most parts of the urban core!
In Columbus OH we have lots of single family zoning and lots of hideous 5 over 1 apartment construction, my question is why the older styles of multi-family housing such as 6/12 unit buildings, row houses, and fourplexes are seemingly “illegal” to build, it’s not simply a matter of SF vs. multi-unit
