McMansions are making LA’s housing crisis a lot worse

There is another cause of overcrowding and homelessness. It is mansionization, the demolition of older, smaller, less expensive houses by real estate speculators who quickly replace them with spec McMansions: boxy, shoddily built houses that max out the permitted building envelope.The disincentive to build multifamily and affordable housing is made worse by the popularity of these easily repeatable home designs, which also cost more to construct while taking up more space and using more water and electricity. Certain communities around L.A. County have developed effective anti-McMansion ordinances that work by limiting the size of structures, although loopholes abound. A possible solution can be  taken from LA's 35 existing community plans, which contain some version of language to “protect existing stable single-family and low-density residential neighborhoods from encroachment by higher density residential uses and other uses that are incompatible as to scale, character, or would otherwise diminish quality of life.”
