Curb Cut Permits

A curb cut is an opening in the curb that allows a vehicle to access private property. Property owners who want to open a new curb cut or modify, expand or move an existing curb cut must apply for a permit from the city before starting construction. 

In order to apply for a curb cut, the property owner must first fill out the Online Permit Application at Application for Driveway Cuts and Openings.

Once the online application is properly filled out and submitted, the application will be:

  1. Reviewed by Inspectional Services. If approved:
  2. Electronically sent on to Traffic, Parking and Transportation, the Historical Commission and the Cambridge DPW. Once approved by these City departments, the application is then:
  3. Placed on the next City Council agenda for final approval. Once the City Council approves the curb cut, the applicant can begin construction.

The Cambridge Traffic, Parking & Transportation curb cut review guidelines include the following: 

  • Curb cuts must have safe sightlines (minimum 20-foot visibility in both directions) for motorists entering the roadway or crossing a public sidewalk.
  • Sidewalks should continue level across the driveway curb cut. 
  • Driveway slopes must not exceed 8% within 15 feet of the public sidewalk or roadway.
  • Curb cuts shall be maximum 20 feet wide in Residential districts and a maximum of 30 feet wide in Open Space, Business and Industrial districts (Zoning Ordinance 6.43.3).
  • Site plans submitted with the application must show driveway and curb cut widths, slopes and distance from nearest intersection.

New or modified curb cuts must be approved prior to the Cambridge Traffic, Parking & Transportation Department’s Building Permit approval.
