NABB's purpose is to combat community deterioration, to preserve and protect the architectural beauty of the Back Bay, and to further Back Bay's residential character.
NABB is a non-profit, charitable organization with a current membership of approximately 2,000. A 50-member Board of Directors, and a 13-member Executive Committee govern NABB.
The bulk of NABB's work is performed by 15 standing committees, covering virtually every neighborhood issue from architectural preservation to zoning enforcement.
NABB's Friends and Neighbors activities join neighbors who share common interests. Currently there are over 20 active Friends and Neighbors groups.
NABB’ office is located in the lower level of the Vendôme Building, 160 Commonwealth Avenue, Boston, Massachusetts 02116. The office is staffed by NABB’s Office Administrator, Emily Fayen, who generally is there during regular business hours on Mondays through Thursdays.
About half of NABB's annual income is derived from membership dues, and most of the remaining income is from special events and fundraising efforts held throughout the year.

- Arlington Street to Park Square on the East
- Columbus Avenue to the New York New Haven and Hartford right-of-way (South of Stuart Street and Copley Place), Huntington Avenue, Dalton Street, and the Mass. Turnpike on the South
