In the United States, preemption is a legal doctrine that allows upper levels of government to restrict or even prevent a lower-level government from self-regulating.

  • Ban-the-box
  • Firearms
  • Mandatory inclusionary zoning
  • Municipal broadband
  • Mandatory paid leave
  • Rent control
  • Full disclosure tax requirements
  • General revenue limits
  • General expenditure limits
