From about 1879 Bell's earliest physics research in Washington.
D.C. was conducted at his first laboratory, a rented house, at 1325 L Street NW, and then from the autumn of 1880 at 1221 Connecticut Avenue NW.
The laboratory was later relocated to 2020 F Street NW sometime after January 1886.
With most of the laboratory's project work being conducted by his two associates, Bell was able to engage in extensive research into the causes of deafness as well as ways of improving the lives of the deaf, leading him to create the Volta Bureau in 1887.
In 1889, Bell and his family moved from their Brodhead-Bell mansion to a new home close to his father, Alexander Melville Bell.
Between 1889 and 1893, the Volta Bureau was located in the carriage house to the rear of the home of Bell's father, at 1527 35th Street NW in Washington, D.C. The work of the Bureau increased to such an extent that in 1893 Bell, with the assistance of his father, constructed a neoclassical yellow brick and sandstone building specifically to house the institution.

The new bureau building was constructed across the street from his father's home, where its carriage house had been its original headquarters.
On May 8, 1893, Bell's 13-year-old prodigy, Helen Keller, performed the sod-breaking ceremony for the construction of the new Volta Bureau building.

The 'Volta Bureau' was so named in 1887 at the suggestion of John Hitz, its first superintendent, and Bell's prior researcher.
Hitz remained its first superintendent until his death in 1908.
Bell's former trust, the Volta Fund, was also renamed the Volta Bureau Fund when the Bureau was established, except for US$25,000 that Bell diverted to the AAPTSD, one of several organizations for the deaf that Bell ultimately donated some $450,000 (approximately $13,000,000 in current dollars) to starting in the 1880s.

The building, a neoclassical Corinthian templum in antis structure of closely matching golden yellow sandstone and Roman brick with architectural terracotta details, was built in 1893 to a design by Peabody and Stearns of Boston.
Its design is unique in the Georgetown area of Washington, due to its Academic Revival style.
It was declared a National Historic Landmark in 1972.

While the Volta Bureau's assigned mission was to conduct research into deafness as well as its related pedagogical strategies, Bell would continue with his other scientific, engineering and inventive works for the remainder of his life, conducted mainly at the newer and larger laboratory he built on his Nova Scotia estate, Beinn Breagh.
Although Bell self-described his occupation as a "teacher of the deaf" throughout his life, his foremost activities revolved around those of general scientific discovery and invention.

By 1887 the Volta Laboratory Association's assets had been distributed among its partners and its collective works had ceased.
In 1895 Bell's father, noted philologist and elocutionist Alexander Melville Bell, who had authored over 45 publications on elocution, the use of visible speech for the deaf and similar related subjects, assigned all his publication copyrights to the Volta Bureau for its financial benefit.
The Volta Bureau later evolved into the Alexander Graham Bell Association for the Deaf and Hard of Hearing (also known as the AG Bell), and its works have actively continued to the present day under its own charter.
