From the article:
‘In Maple Heights, about 72% of lots in single-family districts are too small to fit into the existing zoning code, while 86% are deemed by county planners as too narrow. The city—with assistance from the Cuyahoga County Land Bank—finished two modular houses on three vacant Jefferson Avenue lots last year.
Original properties on the plots were torn down in the 2010s, with the new homes selling for $217,000 and $187,700, respectively.’
