WHAT IS THE DEMOLITION ORDINANCE FOR THE CITY OF CAMBRIDGE?
The Demolition Delay Ordinance (Chapter 2.78, Article II of the Cambridge Municipal Code) was adopted by the City Council in 1979 to afford public review of demolition permit applications for potentially significant buildings. When the Historical Commission determines that a building is significant and should be preserved, demolition will be delayed for up to six months so that solutions can be sought to preserve the building indefinitely. The Ordinance covers all buildings over 50 years old, city-wide. The Historical Commission archives provide dates of construction for all properties in the City.

Demolition is defined in the ordinance as "the act of pulling down, destroying, removing or razing a building or commencing the work of total or substantial destruction with the intent of completing the same." The Inspectional Services Commissioner provided guidelines to outline what actions may require a demolition permit. In addition to complete demolition of a building, the following actions may require a demolition permit,

  • removal of more than 25% of a structure
  • removal of a roof (for example, raising the overall height of a roof, rebuilding the roof to a different pitch, or adding another story to a building)
  • removal of one side of a building
  • gutting of a building's interior to the point where exterior features (windows, etc.) are impacted

Please contact the building inspector at the Inspectional Services Department if you have questions about whether a demolition permit is required for a particular project.

Demolition permit applications can be obtained from the Inspectional Services Department. See Demolition Application Requirements for more information on making an application.  The completed application should be submitted to the Historical Commission, where the staff will review the application. If the Executive Director of the Historical Commission makes an initial determination that the building is significant, a public hearing will be scheduled with Historical Commission.  Posting of a notification placard on the site is required. If the staff makes an initial determination that the building is not significant, the application is released for further review by the Building Commissioner. Applications to demolish utilitarian structures, such as some residential garages, do not generally require a public hearing, however, they do require a review and sign-off from the Historical Commission staff.

When a demolition application is reviewed at a public hearing, the Historical Commission votes on two issues: first, whether the building is in fact significant, and second, whether it is in the public interest that it should be preserved. During this discussion, the Commission will examine the proposed replacement structure. If the Commission finds that a building is significant and preferably preserved, it cannot be demolished for six months from the date of the hearing. In some cases, further action may be taken to permanently protect a significant and "preferably preserved" building or structure through landmark designation or donation of a preservation easement.

WHAT ARE THE CRITERIA FOR DETERMINING A BUILDING'S SIGNIFICANCE?
A "significant building" is one that, according to the City Code, is at least 50 years old and is listed on the National Register of Historic Places, or is a designated landmark, or is in a historic district, or is determined to be "importantly associated with one or more historic persons or events, or with the broad architectural, cultural, political, economic or social history of the City or the Commonwealth, or . . . historically or architecturally significant (in terms of period, style, method of building construction or association with a famous architect or builder) either by itself or in the context of a group of buildings."

A determination that a significant building is "preferably preserved" (relative to the proposed replacement structure) is made if the Commission finds that it is in the public interest that the building should be preserved.

WHAT HAPPENS TO A PREFERABLY PRESERVED SIGNIFICANT BUILDING AFTER THE SIX-MONTH DELAY EXPIRES?
The Commission can initiate a landmark designation study and has passed a policy to consider this action on the fifth month of a demolition delay for all preferably preserved significant buildings. See policy for details. If no action has been taken to designate the building as a landmark and no one is willing to preserve it, then the building can be demolished and the proposed development can proceed, provided that all plans for the use of the site after demolition have been found to comply with applicable laws and all permits and approvals for the development have been obtained. The intent of the delay period is not to prevent demolition but to provide an opportunity for the development of preservation solutions.

All of the Commission's regulatory approvals have a life of six months. This means that once the above conditions have been satisfied, the owner of the property has six months to demolish the building. If the building is not taken down in that period, the Chair of the Commission may issue a six-month extension. If an extension is not issued, the owner must resubmit the demolition permit application for Commission review.
