Full Breakdown
Section 15.04.110 of the Columbus Municipal Code, titled Application--Review, applies before the department, its chief code enforcement officer or any assistant code enforcement officer issues any permit. Three reviews are required. The first confirms that the application complies with the building code. The second, for new construction or extensions to existing structures, determines whether the proposed building site will be reasonably safe from flooding and in conformance with the pertinent laws, rules, regulations and codes of the state of Indiana and the city.
The third review targets construction within a flood prone area. Reviewers must determine that construction materials and utility equipment are resistant to flood damage, that construction methods and practices will minimize flood damage, and that prefabricated, manufactured and mobile homes have adequate protection against flood damage and are designed or modified and anchored to prevent flotation, collapse or lateral movement. The section prints no map reference, elevation figure or freeboard number; it directs the review itself.
The review sits inside the regular permit process. Section 15.04.080 requires a permit before construction, alteration or repair of any building or structure costing more than $300, and Section 15.04.090 requires plans and specifications and, for new structures, a plot plan showing the location of the new structure and all other existing improvements and lot boundaries. Section 15.04.060 incorporates the Indiana building rules in Title 675 of the Indiana Administrative Code, which the building code applies alongside the city's own review. Section 15.04.190 bars a certificate of occupancy unless the construction complies with the chapter.
Flood damage also matters after construction. Section 15.20.040 lists a building or premises damaged by fire, wind, earthquake or flood that becomes an attractive nuisance to children or freely accessible for unlawful acts among the conditions that can mark it as an unsafe building.
Violations & Fines
Construction contrary to the building code is unlawful under Section 15.04.250, and Section 15.04.260 fines each violation not less than $100 nor more than $500, with each day a separate offense and each offense a Class C infraction. The department can serve a written stop order under Section 15.04.180, and starting work before the permit issues doubles the permit fee under Section 15.04.130.
