Historic Districts are groups of buildings, structures, and their surroundings that are architecturally and historically distinctive. Exterior changes to buildings within Historic Districts are subject to review by the Historical Commission made up of residents appointed by the City Manager.

Conservation districts are groups of buildings and their surroundings that are architecturally and historically distinctive. Exterior changes to buildings within NCDs are subject to review by NCD commissions made up of residents appointed by the City Manager. The GIS data layer was created in 2000 from paper documents. Cambridge designated its first NCD in 1984, following City Council legislation the year before allowing NCD establishment.

List of sign permit applications for displaying outdoor signs in Cambridge.

This data set combines information from eight sustainable building certification programs, including two City regulatory programs, to show the extent and location of sustainable buildings in Cambridge.

For inclusion in this data set, a building must meet at least one of the following criteria: receive approval from the City’s Article 22 regulatory process; receive certification from the Passive House program; receive certification from Enterprise Green Communities; or receive LEED certification under a LEED system that requires the whole building to meet sustainability standards.

Some buildings meet two or more of these criteria. Information provided about the applicable sustainable building programs for qualifying buildings includes certification levels, certification types, ratings, or scores. Additionally, this data set contains information about other certifications (ENERGY STAR, Fitwel, and WELL) that may apply to covered buildings. If a covered building participates in the City’s BEUDO regulatory process, this data set provides two key emissions figures for the building.

In this dataset, we use Cambridge GIS Building IDs as unique identifiers for certified sustainable buildings. Building IDs refer to one physical structure, even if there are multiple street addresses associated with that structure.
