CT HB06683

Expands the definition of public nuisance to include properties where enumerated offenses have occurred, not just properties used for certain purposes.

Adds four new offense categories that trigger public nuisance actions: firearm offenses, illegal drug manufacture/sale/possession, and three specific municipal ordinance violations (excessive noise, overcrowded dwellings, unlicensed massage operations).

Changes the evidentiary standard for establishing public nuisance from "clear and convincing evidence" to "a preponderance of the evidence" at both the show cause hearing and evidentiary hearing stages.

Permits citations for municipal ordinance violations (in addition to arrests and arrest warrants) to satisfy the three-incident threshold required to commence a public nuisance action.

Allows financial institution defendants to assert an affirmative defense that they took reasonable steps to abate the nuisance but were unable to do so, with burden of proof on the defendant.
