This bill introduces new sections to the North Dakota Century Code that establish regulations for nonconforming structures in residential zoning districts across counties, cities, and townships. 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.

Additionally, the bill outlines that expansions of nonconforming structures are generally prohibited unless they comply with existing zoning ordinances. It also emphasizes the need for compliance with floodplain management ordinances to maintain eligibility in the national flood insurance program. The zoning authority is granted the power to create less restrictive regulations if deemed necessary, and it is mandated to issue building permits unless the proposed work violates specific conditions outlined in the bill. The definition of a "nonconforming structure" is also clarified, indicating that it refers to structures that were legal prior to changes in zoning ordinances.
