484 Beacon was designed by Ernest N. Boyden, architect, and built in 1892-1893 by Eugene H. Fay, builder, probably for speculative sale. It was one of five contiguous houses (482-484-486-488-490 Beacon). He is shown as the owner on the original building permit applications for 484-490 Beacon, all dated June 11, 1892 (the application for 482 Beacon has not been located).
By the 1893-1894 winter season, 484 Beacon was the home of Mrs. Mary (Hasbrouck) Sutton, widow of General Eben Sutton, owner of textile mills in North Andover, and their daughter, Eliza (Lila) (Sutton) Young, the widow of Harvard professor Ernest Young. They previously had lived at 501 Beacon. Lila S. Young is shown as the owner of 484 Beacon on the 1895 and 1898 Bromley maps.
They continued to live there during the 1897-1898 winter season, but moved soon thereafter. In June of 1899, Eliza Young remarried, to John Hasbrouck Scoville, a banker and broker, and by 1900, the Scovilles were living in New York City and Mary Sutton was living in Cambridge.
The Sutton family continued to own 484 Beacon and Lila S. Young continued to be shown as the owner on the 1908 and 1912 Bromley maps.
During 1898-1899 winter season, it was the home of William Jones Ladd and his wife, Anna Russell (Watson) Ladd. William Ladd was a civil and mining engineer. Their primary residence was in Milton.

By 1900-1901 winter season, it was the home of Miss Ellen Maria Chandler. She previously had lived at 346 Beacon. She continued to live at 484 Beacon until her death in April of 1908.
By 1909, 484 Beacon was the home of Dr. Francis P. Emerson and his wife, Rena P. (Colby) Emerson. They previously had lived at 1075 Boylston.
Francis Emerson was an ear, nose, and throat specialist. He also maintained his medical office at the house, along with Dr. Charles R. C. Borden, who lived in Brookline. Francis and Rena Emerson continued to live there during the 1912-1913 season, after which they moved to Brookline.
In early 1914, 484 Beacon was purchased from Lila (Sutton) Young Scoville by William J. Stober, a real estate agent and conveyancer. The transaction was reported in the Boston Globe on February 26, 1914. He is shown as the owner on the 1917 Bromley map.

By the 1917-1918 winter season, 484 Beacon was the fraternity house of the Iota Tau Chapter (MIT) of Sigma Alpha Epsilon. In July of 1921, the Massachusetts Iota-Tau Association acquired 484 Beacon from William Stober. The Iota-Tau Association is shown as the owner on the 1928 and 1938 Bromley maps.
In March of 1960, the Iota-Tau Association acquired 480 Beacon and converted it into another Sigma Alpha Epsilon fraternity house.
The fraternity remained there until 1999. In October of 1999, the Boston Licensing Board revoked the fraternity’s dormitory license because of illegal consumption of alcohol by minors and repeated complaints by neighbors.
In October of 2001, 484 Beacon was purchased by the 484 Beacon St. LLC from the 484 Phi Alpha Foundation.
In January of 2003, it converted the house into four condominium units, The 484 Beacon Street Condominium.
