Overview:
Many cities have taken steps to prevent federal immigration enforcement from using local government property for operations such as staging, processing, or detaining individuals.
These policies help clarify boundaries, protect public spaces, and ensure that local resources are not used to support civil immigration enforcement.
Key cities are taking action:
- Prohibiting the use of city property
Cities can issue executive orders or pass ordinances that restrict the use of publicly owned buildings, parking lots, and other facilities for immigration enforcement activities. - Requiring warrants for non-public access
Federal agents may be denied access to non-public areas of government buildings unless they present a valid judicial warrant. - Identifying and securing vulnerable locations
Cities can inventory publicly owned properties and determine which spaces could be used for enforcement operations, then apply restrictions accordingly. - Posting clear signage
Signage can be used to designate restricted areas and communicate access rules to both staff and federal agents. - Training staff on enforcement protocols
Employees should be trained on how to respond if federal agents arrive, including whom to contact and how to handle access requests.
Examples from other cities:
- Chicago, IL
Issued an “ICE Free Zone” executive order prohibiting the use of city property for civil immigration enforcement activities. - Minneapolis, MN
Restricted use of city-owned parking lots, garages, and public spaces for enforcement operations and required departments to post signage reinforcing the policy. - Boston, MA
Barred federal agents from using city buildings, parks, and other public property for enforcement staging or operations. - San Jose, CA / Santa Clara County
Coordinated efforts to identify public properties and develop policies restricting how federal agencies can use those spaces.

Why this Matters:
Restricting the use of local property helps cities maintain control over public resources, reduce the visibility and impact of enforcement activity, and provide clear guidance to staff and residents.
