Sidewalk Obstruction Permit Application


A Sidewalk Obstruction permit is required for any type of sidewalk obstruction in the right-of-way in the City of Cambridge. 

The first step to applying for any permit is to register with a user name and password (top left hand corner of screen).  Once in the system, make sure you understand and meet all of the permit requirements before starting the application process as permits will not be issued until all requirements are met. 

NOTICE  Methods of payment include:  Visa, MasterCard or Discover credit cards, Visa & MasterCard debit cards or Electronic check (E-checks).  A convenience fee will be charged for each purchase:  2.5% of the purchase for Visa, MasterCard or Discover and a $2.00 flat fee for payments made by E-check.  Learn more about online payments and convenience fees.  You will be taken to a secure, third party, payment processor, Velocity Payment Systems to submit payment online.

If you have any questions, please call the Permit Desk at 617.349.4833 or email
