The Commission for Historical and Architectural Preservation (CHAP) was established in 1964, and is currently governed by Article Six of the Baltimore City Code.  Today CHAP oversees 33 local historic districts, over 200 landmarks, and manages a local historic preservation tax credit program.  CHAP helps preserve and revitalize neighborhoods, celebrates City history, and promotes historic preservation as a proven economic driver for Baltimore City.  The mayoral appointed Commission and its staff are located within the Department of Planning.
