N.D. Cent. Code § 57-02.2-03
Improvements to commercial and residential buildings and structures as defined in this chapter may be exempt from assessment and taxation for up to five years from the date of commencement of making the improvements, if the exemption is approved by the governing body of the city, for property within city limits, or the governing body of the county, for property outside city limits. The governing body of the city or county may limit or impose conditions upon exemptions under this section, including limitations on the time during which an exemption is allowed. A resolution adopted by the governing body of the city or county under this section may be rescinded or amended at any time. The exemption provided by this chapter shall apply only to that part of the valuation resulting from the improvements which is over and above the assessed valuation, exclusive of the land, placed upon the building or structure for the last assessment period immediately preceding the date of commencement of the improvements. Any person, corporation, limited liability company, association, or organization owning real property and seeking an exemption under this chapter shall file with the assessor a certificate setting out the facts upon which the claim for exemption is based. The assessor shall determine whether the improvements qualify for the exemption based on the resolution of the governing body of the city or county, and if the assessor determines that the exemption should apply, upon approval of the governing body, the exemption is valid for the prescribed period and shall not terminate upon the sale or exchange of the property but shall be transferable to subsequent owners. If the certificate is not filed as herein provided, the assessor shall regard the improvements as nonexempt and shall assess them as such.
