How to apply for a parking freeze permit

Last updated:

Whether you apply for a new or modified parking freeze permit, it’s the same process.


Is your project in a parking freeze zone?

Projects that fall within a parking freeze zone may require approval by the Air Pollution Control Commission (the Commission). You can enter your address on our online map to check if you are in a parking freeze zone.

If you have any additional questions about the need for a parking freeze application, contact the Commission.


Do you need to apply in Downtown (Boston Proper)?

Projects that include residential parking only do NOT need to apply for a Downtown parking freeze permit or exemption certification. A residential project that includes any employee or staff parking must apply for an exemption certification.

For all other projects you MUST apply for a Downtown parking freeze permit or exemption certification. This includes permit modifications.

All projects located within the Downtown Parking Freeze Zone are encouraged to contact the Commission. For any project with residential parking only, you may request that the Commission grant you a letter of exclusion, certifying that the project is excluded from the Commission's jurisdiction.


Do you need to apply in South Boston?

There are three zones covered by the South Boston Parking Freeze area:

  • the Piers zone
  • the Commercial and Industrial zone, and
  • the Residential zone.

You do NOT need to apply for a South Boston parking freeze permit if:

  • you want to create a parking facility that is reserved for building residents and the ratio of parking spaces to housing units is one-to-one (1:1) or less,
  • you want to create new residential parking spaces in the residential zone and the spaces are for a residence in that zone, or
  • you want to create new commercial parking spaces in the residential zone, and the spaces are for a business in that zone.

For all other projects, you MUST apply for a South Boston parking freeze permit. This includes permit modifications.


Do you need to apply in East Boston?

There are no spaces available in the East Boston parking freeze bank. The Commission is not accepting applications for new parking freeze permits in East Boston.



For a parking freeze permit modification, please contact A modification constitutes any of the following:

  • changes to the overall number of parking spaces,
  • changes in the use of the parking spaces,
  • changes in the layout of the facility,
  • changes in the ingress or egress of the facility, or
  • changes in the ownership of the facility.
