limiting the use of state, county, and municipal funds and property for construction and operation of certain immigrant detention facilities.

HB 1609 prohibits New Hampshire state, county, and municipal governments from using public funds or property to build, operate, or pay for immigrant detention facilities, particularly those managed by private companies. It bans spending on construction, renovation, repurposing public property for detention, selling public property for such use, and making payments to private detention operators. The bill does not affect existing 287(g) agreements between local law enforcement and federal immigration authorities or the provision of health and safety services to detained individuals. Counties may face potential revenue losses if they stop cooperating with federal immigration programs, but municipalities are not expected to have financial impacts.
