A municipality may appoint and commission as many code enforcement officers as may be necessary for the proper security, general welfare, and convenience of the municipality. These officers are vested with all the powers and duties conferred by law upon constables in addition to duties imposed upon them by the governing body of the municipality. However, no code enforcement officer commissioned under this section may perform a custodial arrest. These code enforcement officers shall exercise their powers on all private and public property within the municipality.
