This bill proposes the creation of new sections in the North Dakota Century Code that specifically address the treatment of nonconforming structures in residential zoning districts. It allows for the repair, replacement, improvement, maintenance, restoration, or rebuilding of nonconforming residential structures that have been damaged beyond fifty percent of their value, provided certain conditions are met. These conditions include submitting a building permit application within six months of the damage, beginning restoration within one year, and ensuring that the new structure does not exceed the original in size, height, or number of stories, among other stipulations. The bill also emphasizes that expansion of nonconforming structures is generally prohibited unless compliant with zoning ordinances.

Additionally, the bill outlines that local zoning authorities have the power to regulate these nonconforming structures, particularly in floodplain areas, to maintain eligibility for the national flood insurance program. It allows for the issuance of building permits unless the proposed work violates specific zoning regulations. The definition of a "nonconforming structure" is clarified as a structure that was legal prior to a change in law that rendered it nonconforming. Overall, the bill aims to provide a framework for managing nonconforming residential structures while ensuring compliance with local regulations and safety standards.
