How parking affects missing middle housing
Missing Middle Housing types are key to affordability, but parking (and zoning that requires off-street parking) impacts the cost. This analysis by Dan Parolek of Opticos Design, author of Missing Middle Housing, shows that fourplexes—one missing middle type—may yield from 21 to 49 units per acre, depending on their number of bedrooms and the off-street parking provided. In other words, parking can cut the net density in half. The buildings with no parking may achieve higher densities and lower costs. (In an urban neighborhood, on-street parking is typically available).
