Sec. 26. (a) The legislative body of the county or municipality may declare:
(1) a building erected, raised, or converted; or
(2) land or premises used;
in violation of an ordinance or a regulation adopted under this chapter or under IC 13-2-22.6 (before its repeal) to be a common nuisance. The owner of the building, land, or premises is liable for maintaining a common nuisance.
(b) If penalties have been provided for violation of an ordinance, the attorney of the county or municipality shall, upon receipt of information of a violation of an ordinance or a regulation adopted under the county's or municipality's authority, make an investigation of the alleged violation. If the facts are sufficient to establish a reasonable belief that a violation has occurred, the attorney may file a complaint against the violator and prosecute the alleged violation.
