If a property has been declared a public nuisance in the City of Dayton, there is a duty to vacate the premises because the property endangers the life, health, safety, or welfare of the general public or the property's current occupants. Posting a bond allows the occupants to remain on the premises; however, the bond is conditioned on the owner immediately rehabilitating or removing (abating) the nuisance. If the nuisance is not abated, the city may demolish the property and bill the owner for the cost. In addition, there are criminal penalties associated with failure to abate a public nuisance. I strongly suggest that you contact a real estate attorney if you have additional questions. There may be a right to appeal the legal or factual issues relating to the nuisance notice.
