The James Cassidy House, located at 33 King Rd. in Park City, Utah, was built . It was listed on the National Register of Historic Places in 1984.
It was deemed significant as an example of the T/L cottage style, and may have been a T/L cottage formed by an addition. The T/L cottage by addition "resulted from the addition of a cross-wing to an existing hall and parlor house"; the style was "the most common and acceptable" way to enlarge Park City homes, and represents an important construction trend in the city.
