It is accessible to children or others who may not be aware of its existence, or who may not realize the extent of the danger or take proper precautions to avoid injury to themselves or others, or
Its proximity to a public street or way, or to a private street or way used with more than occasional frequency by persons other than the owner or occupant of the land, unreasonably increases the hazard to pedestrian or vehicular traffic;
D. Any building or structure that has been constructed, erected, set up, altered, enlarged, converted, moved or maintained or that is permitted or suffered to remain in existence, in violation of any provision of this code or any provision of any ordinance of the city or of any statute of the state or any lawful order or regulation of competent authority thereunder;

F. Any use of land or of any building or structure which is in violation of any provision of this code or of any other ordinance of the city;
G. Any use of land or of any building or structure which is in violation of any term or condition of any permit granted by the council or the planning commission pursuant to the authority of any provision of this code or any other ordinance of the city, which permit authorizes a conditional or nonconforming use of the land, building or structure, or which imposes conditions or restrictions upon the conduct of any business, activity, pursuit or calling upon the land or within the building;

All laws applicable to the levy, collection and enforcement of municipal taxes shall be applicable to the special assessment provided for in this chapter.
E. If the costs specified in subsection (A) of this section are not paid within fifteen days of the notice provided under subsection (B) of this section and no appeal is timely made on the city council, the unpaid costs shall become a personal obligation of the responsible party(ies), and each of them, jointly and severally, and the city attorney is authorized to pursue collection of these costs by all appropriate legal means.
