The Cambridge City Council’s Ordinance Committee voted to move to the full Council Councillor Zondervan’s proposed amendment to BEUDO. The amendment was revised, pursuant to a suggestion from CDD, to accelerate the net zero deadline to 2030 for nonresidential buildings of 25,000 sf or more that apply for a building permit on or after January 1, 2025.

CDD’s suggested language was made after meetings with various stakeholders, not including the KSA and other business associations involved in the comprehensive BEUDO amendments approved in June 2023. CDD suggested two changes: that “new” buildings be defined based on the date of building permit application, rather than certificate of occupancy, and that it apply to buildings which apply for a building permit as of January 1, 2025 rather than 2024.

Vice Mayor Mallon moved to send the amendment to the Council with a negative recommendation; that motion failed on a 5-4 vote (voting no: Councillors Azeem, Mallon, Simmons, and Toner). The Council then voted to move the amendment to the full Council. The amendment may be considered at the final session of this City Council on December 18th, or may be moved into the next term, according to the City Clerk.

The Cambridge City Council Ordinance Committee addressed two sustainability-related topics this month. First, the City Council voted to apply to be a part of the Commonwealth’s Fossil Fuel Free demonstration program (also known as the “gas ban”), with an exception for restaurants that passed on a 5-4 vote. Second, the City’s Ordinance Committee continues to have under consideration another proposed BEUDO amendment, aimed at accelerating the net-zero deadline to 2030 for non-residential buildings of 100,000 sq. ft. or more.

On June 26, the Cambridge City Council approved the June 22 version of the BEUDO amendments, with a clarifying amendment on cogeneration, and additional clarifying amendments on the definitions of “campus” to make clear that a campus can include buildings smaller than 25,000 sf (which would not otherwise be covered by BEUDO) and “owner” to include affiliates and subsidiaries. The amendments passed with a vote of 8 Councilors in favor, and Councilor Denise Simmons voting “present”.

The Council declined to adopt Councilor Zondervan’s proposed amendment to require new buildings to be net zero by 2030, that amendment was referred to the Ordinance Committee. 

The Council also focused on what it needed to do to timely submit its application to participate in the Commonwealth’s fossil free demonstration program. The application is due by September 1, and CDD plans to host public sessions in July to provide information and gather input.

June 6, 2023

On June 5, the City Council reviewed the BEUDO amendments drafted by the City’s Community Development Department, but deferred a vote for two weeks.

The Council will consider the amendments again at its June 26 meeting (there is no meeting in two weeks due to the Juneteenth holiday). Councillors agreed to defer consideration because the amendments were only made publicly available last Thursday, June 1, the amendments are technical and complex, and they want to give people ample time to review the amendments and make any needed minor changes or “tweaks.”

The City of Cambridge’s Ordinance Committee held a meeting on Wednesday, April 12th, to hear the Community Development Department’s (CDD) proposed changes to the BEUDO amendment. The changes include introducing:

  • Two net zero deadlines based on the size of the building–non-residential buildings of 100,000 or more sf must achieve net zero by 2035, while buildings of less than 100,000 sf have until 2050 to achieve net zero; 
  • Offsets to ensure feasibility with 2035 target; 
  • A Review Board for case-by-case deferrals and exemptions; and 
  • A Policy Review to be completed in 2031 to assess BEUDO’s effectiveness. 

The hearing featured robust public commentary from MIT, Harvard, business associations including the Kendall Square Association, condo associations, and sustainability advocates.
