476 Beacon is located on the north side of Beacon, between Hereford and Massachusetts Avenue, with 474 Beacon to the east and 478 Beacon to the west.

476 Beacon was designed by Fehmer and Page, architects, and built in 1891-1892 by Thomas J. Lyons, mason, as the home of retired merchant Edward Frothingham and his wife, Eugenia (Mifflin) Frothingham. He is shown as the owner on the original building permit application, dated November 2, 1891, and on the final building inspection report, dated December 3, 1892.

Eugenia Frothingham purchased the land for 476 Beacon on October 16, 1891, from building contractor George Wheatland, Jr., who had purchased it on that same day from the Boston and Roxbury Mill Corporation.

The deeds from the Boston and Roxbury Mill Corporation for the land between Hereford and Massachusetts Avenue included language specifying that only dwellings and associated outbuildings (including stables) could be built on the land and that the buildings were to be set back 20 feet from Beacon. The deeds for the land between 460 Beacon and Massachusetts Avenue were entered into in the early 1890s and also included restrictions limiting to one story any building in the rear north of a line 90 feet from Beacon. The deeds for the land between Hereford and 458 Beacon, which were from 1886, did not include language limiting buildings in the rear. As a result, the owners of the land at 448-458 Beacon entered into individual agreements to limit the depth of the houses that were built on their land and restrict the height of outbuildings in the rear to one story. On August 2, 1909, all of the owners of the property on the north side of Beacon between Hereford and Massachusetts Avenue (other than the Mt. Vernon Church) entered into an agreement to “continue for twenty years longer [to December 31, 1929] the existing freedom from irregular building and obstruction of view which they now enjoy from the rear portion of their houses.” On December 30, 1929, the owners of 448-480 Beacon extended this agreement to expire on December 31, 1939.
