The Development Log provides an record of large-scale development projects occurring in the City of Cambridge. The Log, updated on a quarterly basis, is distributed to City departments and the public to keep them posted about development progress, from permitting through construction to completion. The Historical Projects table include information about projects completed prior to 2023. The table includes general project information, such as development status and statistics related to the entire project. Limited information is available projects completed prior to 2011.

Since a project may include more than one use, data on each specific use found within a project is found in the associated Project Use table found here: https://data.cambridgema.gov/Planning/Development-Log-Historical-Projects-Use-Data/r5mv-isth.

Short-term rentals in Cambridge. Short-term rental (STR) refers to the rental of any dwelling unit of bedroom as residential accommodation for a duration of less than 30 consecutive days.

This table includes residential building permits issued from 1996 through June 30, 2023. Each listing includes the permitted address, map-lot parcel identification number, Cambridge neighborhood, prior use, permitted use, number of permitted units, and number of units lost or gained,

The date reflects the year during which a building permit was first issued for a development project. This is not an indication of the date of completion. This list only includes projects that removed an existing building, constructed a new building or combined or split units within an existing structure. Major rehabilitation projects that did not change a structures unit count are not included here. All data is subject to revision.

Data sources include the Cambridge Assessing Department, the Cambridge Development Log, and the Cambridge Inspection Services Department.

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.

Commercial parcel data for fiscal year 2015, including sales, land and building data

List of permits related to the construction or the alteration of existing buildings in Cambridge. These permits cover construction that changes the structure, the footprint, or the volume of the building. This includes decks, porches, and additions, as well any reconstruction, renovation or repair to an existing structure. This dataset derives from Cambridge's ViewPoint permitting system.

Variances and Special Permits with status of under review, approved, denied or withdrawn. Cambridge's Board of Zoning Appeal hears and decides appeals, applications for special permits, and appeals and petitions for variances from the terms of the Cambridge Zoning Ordinance. This dataset includes available records from October 1, 2013 through current. This dataset does not currently include data from a relatively small number of cases with the type "appeal," because these cases are structured differently from the more common variance and special permit type cases.
