The Board of Standards and Appeals (BSA, or Board) was first created in 1916 along with NYC's historic first Zoning Resolution.
Initially, the Board was comprised of 9 members, 6 of whom were appointed commissioners, 2 FDNY members, and 1 DOB superintendent. Separately, a Board of Appeals was created with 6 appointed members and 1 FDNY chief.
In 1925, the BSA absorbed the Board of Appeals and was restructured to 4 appointed commissioners and 1 FDNY chief.
In subsequent years, the BSA would grow and shrink between 3 to 6 appointed commissioners. Since 1991, the Board has been comprised of 5 appointed commissioners.
