Irrigation Requirements

Irrigation systems are required to have rain and freeze sensors in compliance with state design and installation regulations. The effective date for this requirement depends upon the installation date and type of system.
  • Any commercial or industrial irrigation system installed on or after June 1, 2007, must be equipped with rain and freeze-sensing devices. Any commercial or industrial irrigation system installed before June 1, 2007, must be retrofitted with similar rain and freeze sensors.
  • Any residential irrigation system installed on or after September 1, 2007, is required to have rain and freeze sensors.
