Willmar, Minn., Code of Ordinances ch. 6.5, art. II § 6.5-69

(a) No person shall operate a rental unit unless he holds a current, unrevoked operating license issued by the appropriate authority in his name for the specific named rental unit. Failure to comply with this requirement shall result in certain fees being charged to the owner as per the schedule set forth in the housing inspection plan.
(b) Every operating license shall be issued for a period of time in accordance with the plan for the systematic inspection of rental housing units to be developed by the appropriate authority pursuant to section 6.5-67 .
(c) The appropriate authority is hereby authorized upon application therefor to issue new operating licenses, and renewals thereof, in the names of applicant owners or operators of rental housing units. No such licenses shall be issued unless the rental housing unit in connection with which the license is sought is found after inspection to meet all applicable requirements of this article and applicable rules and regulations pursuant thereto.
(d) No operating license shall be issued or renewed unless the applicant owner or operator has first made application therefor on an application form provided by the appropriate authority. The appropriate authority shall develop such forms and make them available to the public.
(e) No operating license shall be issued or renewed unless the applicant owner or operator agrees in his application to such inspection pursuant to sections 6.5-67 (a) and 6.5-68 (a) as the appropriate authority may require to determine whether the rental housing unit in connection with which such license is sought is in compliance with the applicable provisions of this article and with applicable rules and regulations pursuant thereto.
(f) No operating license shall be issued or renewed unless the completed application form is accompanied by payment of a license fee pursuant to the schedule of fees included in the inspection plan developed by the appropriate authority.
(g) No operating license shall be issued or renewed for a nonresident applicant (a property owner living outside the county), unless such applicant designates in writing to the appropriate authority the name of his agent for the receipt of service of notice of violation of the provisions of this article and for service of process pursuant to this article.
(h) No operating license shall be issued or renewed for a resident applicant unless such applicant has first designated an agent for the receipt of service of violations of the provisions of this article, when said applicant is absent from this city for 30 or more days. Such a designation shall be made in writing and shall accompany each application form. The applicant may designate any person resident in the County as his agent for this purpose or may designate the appropriate authority as his agent for this purpose.
(i) No operating license shall be renewed unless an application therefor has been made within 60 days prior to the expiration of the present operating license.
(j) Each license shall be displayed in a conspicuous place within the rental housing units. Any license for a particular property shall be transferable to another person, provided that the person holding the operating license must give notice in writing to the appropriate authority within 15 working days after having transferred or otherwise disposed of the legal control of the licensed rental housing unit. Such notice shall include the name and address of the person or persons succeeding to the ownership or control of such rental housing unit. Failure to provide proper notification of a transfer of property shall be cause for the property to be re-registered and the appropriate fee charged.
(k) Whenever upon inspection of the licensed rental housing unit the appropriate authority finds that conditions or practices exist which are in violation of the provisions of this article or of any applicable rules and regulations pursuant thereto, he shall serve the owner or operator with notice of such violation in the manner hereinafter provided. Such notice shall state that unless the violations cited are corrected within reasonable time, the operating license may be suspended.
(l) At the end of the time he has allowed for correction of any violation cited, the appropriate authority shall reinspect the rental housing unit and if he determines that such conditions have not been corrected, he may issue an order suspending the operating license.
(m) Any person whose license to operate a rental housing unit has been suspended shall be entitled to a reconsideration of the order by an administrative conference or by an appeal in the manner hereinafter provided by this article. If no request for reconsideration or appeal reaches the appropriate authority within 21 days following the issuance of the order of suspensions, the license shall be revoked, except that prior to revocation any person whose license has been suspended may request reinspection, upon a showing that the violation or violations cited in the notice have been corrected.
(n) If, upon reinspection, the appropriate authority finds that the rental housing unit in connection with which the notice was issued is now in compliance with this article and with applicable rules and regulations issued pursuant thereto, he shall reinstate the license. A request for inspection shall not extend the suspension period unless the appropriate authority grants such request.
