Northfield, Minn., Code of Ordinances ch. 14, art. III § 14-93

(a) Initial issuance. The building official shall issue a license for the building after an application has been completed pursuant to section 14-91 (a) and an inspection of each unit pursuant to section 14-96 , the building official finds that the units meet or exceed the minimum requirements set forth by this article.
(b) Determining license category. License categories are based on property and nuisance code violations found during the initial, renewal, owner-requested, or complaint-based inspections, as listed in table 14.92. Each inspection shall serve as a verification of the category of license issued to the property. Based on the outcome of any inspection, a property may move from a lower-numbered category of license to a higher numbered category.
(c) Contents of license. A rental license shall show the date of license issuance, the maximum occupancy for which the unit is approved, the category of license issued, the type of improvement plan if one is required as part of the license category, the term of the license, and the expiration date of the license.
(d) Nontransferable. Licenses issued pursuant to this article are nontransferable.
(e) Sale of property. When a licensed rental property is sold, the new owner shall apply for a new rental license in the name of the new owner within 30 days of closing on the sale. The property may be required to be re-inspected prior to issuance of the license, in the discretion of the building official. If the property is not re-inspected, the new property owner shall be issued a Type II license unless the unit was subject to an improvement plan or is a short-term rental. If the property was subject to an improvement plan, the new owner shall be issued a Type III or Type IV license, respectively, until such time as the new owner can show compliance with the improvement plan. If a new license is not issued within 60 days of closing on the sale of the property, or a longer period as allowed in writing by the building official, the property shall cease being rented and shall not be rented again until a new rental license is issued.
(f) Renewal. A rental housing license shall expire at the end of the respective license period listed in table 14.92. A renewal license shall be applied for at least 30 days prior to expiration of the existing license. A late fee in an amount established by resolution of the city council from time to time will be charged for renewal license applications that are not applied for at least 30 days prior to expiration of the existing license. The property shall not be occupied by a tenant after expiration of a license, provided that the building official may issue a temporary renewal license not to exceed two months in duration if the building official deems it appropriate to allow continued occupancy pending issuance of a renewal license. A temporary renewal license shall expire on the stated date and the property shall not continue to be occupied by a tenant unless a full renewal license has been issued by that date.
