The Cambridge Historical Commission (CHC) is the city's historic preservation agency and seeks to preserve the integrity and diversity of Cambridge's built environment and to disseminate information about its history. The CHC protects designated properties throughout the city and preserves the integrity of Cambridge's many significant buildings. The CHC advises private and commercial owners, institutions, and public agencies on historic preservation issues, and participates in reviews of state and federal projects that impact historic resources.

The CHC maintains a public archive on the city's history. The collection focuses on the city's architectural and social history and contains information on all 13,000+ Cambridge buildings. It also includes thousands of historic photographs and maps as well as information on many individuals and organizations.

Neighborhood Conservation Districts were established by City ordinance in 1983. Conservation district designation recognizes a distinctive physical environment that reflects the architectural, cultural, political, economic, or social history of the city. NCDs foster wider public knowledge and appreciation of such neighborhoods. Designation encourages the conservation and maintenance of these areas so that the city may be a more attractive and desirable place in which to live and work. The deadline for submitting applications is November 30, 2021.
