Boston’s tiniest homes clustered in some of its most expensive neighborhoods

Boston’s 13 tiniest homes—all condos—are clustered in some of the city’s most expensive neighborhoods, including Back Bay, the South End, and the North End.

Some can also be found in Fenway, Kenmore, and South Boston.

That is according to an analysis of market-rate listings at the start of August from real estate research site NeighborhoodX. The analysis found that the units, ranging from 273 square feet to 435 square feet, run in price from $780 to $1,446 per square foot.

”In other words, smaller spaces can often command more per square foot than do larger ones in the same building or neighborhood,” NeighborhoodX research director Constantine Valhouli said over email. See below for a sharper breakdown.
