133 E. Lime Avenue
Lot 21, Block B in the Town of Monrovia Subdivision lay unimproved until 1908 when Byron Clark built a two-storey house that would be a boarding house that provided furnished rooms for renters. The structure kept its function asa boarding house until it was torn down in the late 1950s.
The Sanborn maps show a two-storey, rectangular structure which is very common for commercial structures of that time. It was wood frame and had enough rooms to rent to ten people.
By 1921, Margaret Clark had died, and her husband moved to Anaheim to live with one of his daughters. They sold the business and the property, and the boarding house became the Ak-Sar-Ben Rooms in 1924. The owners then added a small dwelling at the back of the property by the alley with an address of 133 1/2 E. Lime Avenue.
