Extract of Cambridge Assessing Department on-line property database file for FY17. Contains residential, condo, commercial and exempt data. Please see attached Cambridge Property Data Metadata for field description.

This dataset contains compliance status and energy and water use data gathered under the Building Energy Use Disclosure Ordinance (BEUDO) program. Property details, energy use and water use data are submitted by property owners or managers whose properties are subject to BEUDO through an online tool called ENERGY STAR Portfolio Manager. Parcel level property information is obtained from the City of Cambridge Property Database.

Energy and water use information submitted by property owners and managers is shown for properties that first began reporting data on energy used in 2015. Energy use for the listed Data Year is required to be reported by May of the next year. Properties subject to BEUDO reporting include: - nonresidential properties 25,000 square feet or more, - residential properties with 50 or more units and - municipal properties 10,000 square feet or more.

Reports may include data on one or more buildings. The specific building IDs included (from the Cambridge GIS Building Footprints layer) are listed in the Buildings Included column. The report level is the most detailed level of energy use available - if multiple buildings are included in a report, we do not have energy use on the individual buildings, only the group. Building IDs and what they refer to have changed over time, even for buildings that did not change. To ensure you are using only comparable data when comparing reports over time, you should only make direct comparisons for reports with the same Reporting ID.

Properties with no energy data included are those that were identified as being subject to BEUDO for the given Data Year, but which did not submit a report.

Note that the City of Cambridge makes all efforts to acquire accurate data from BEUDO properties. The data may still contain errors or omissions. Under the 2023 amendments to the BEUDO ordinance, reporters will be required to get third-party verification of their reporting data.

View records about wells in Massachusetts, including location, well depth, and condition. Data spans 1962 to present day.

This polygon layer contains all of the property parcels in Cambridge. Each parcel has a unique Map and Lot ID number that links it to a record in the Assessing Department's Vision database system. Created for internal use by the Assessing Department to provide a visual reference associated with each parcel in the CAMA database. Created for interdepartmental and external use as part of the web viewers on the City's website. Also created for addressing/geocoding needs, although the Buildings and Master Address List are currently more accurate than Parcels. NOTE: The Parcels GIS data layer is NOT used by Assessing to calculate land area or taxes. Assessors refer to actual deeds or plans accepted by the Massachusetts Land Court. The figures stored in the GIS data layer are for general reference purposes only.
