Prior to 1972, City Hall was not wheelchair accessible. The only way in was through Councilman Tom Bradley’s office.
It was not until Activist Norma Jean Vescovo asked Councilman Bradley that if he became Mayor, to make City Hall more accessible. In 1973, Mayor Bradley created City of Los Angeles Department on Disability and added ramps.
