Champlin, Minn., Code of Ordinances ch. 30, art. II § 30-28

(a) First instance. The enforcement officer shall, upon the first instance of conduct described in section 30-27 notify in writing by first class mail the licensee and tenant of the violation and direct the licensee to take steps to prevent further violations.
(b) Second instance. If, within 12 months of the notification described in section 30-28 (a) of such behavior at the same dwelling unit or at a dwelling unit covered by the same license, another instance of disorderly behavior occurs, the enforcement officer shall notify the licensee and tenant in writing by first class mail of the violation and shall direct the licensee to submit to the enforcement officer, within ten days of the date of the notice, a written report of all actions taken since the first violation notice and actions the licensee intends to take to prevent further disorderly behavior.
(c) Third instance. If, within 12 months after the date of the notice described in section 30-28 (b), another instance of disorderly behavior occurs at a dwelling unit covered by the same license, the rental license may, following an opportunity for the licensee to be heard by the city council, be revoked, suspended or not renewed by the city council upon the recommendation of the enforcement officer. The enforcement officer shall submit a written description of the disorderly conduct and recommendations for action to the city council and licensee within 20 days of the service of third notice on licensee of disorderly behavior. Licensee's opportunity to be heard by city council under this paragraph is subject to written request for hearing to the city within ten days of the date of submission of the enforcement officer's description of conduct and recommendations for action.
(d) Nuisance property. If the occupants or visitors to a particular dwelling unit cause multiple police calls to the unit for disorderly or disruptive behavior, the city council may deem the dwelling unit a public nuisance and take action pursuant to sections 30-28 and 30-29 .
(e) Postponing license action. No action to suspend or revoke a license if the licensee is actively, diligently, in good faith and without delay pursuing an unlawful detainer action against tenants of the licensed dwelling if the removal of those tenants, in the opinion of the enforcement officer, will cure the violations for which action to revoke or suspend have been recommended to the council. In such cases the licensee shall be allowed a reasonable time to complete the eviction process, but not more than 60 days from the date of the third instance of disorderly behavior.
(f) Determining disorderly behavior. A determination that the licensed dwelling unit has been the location of disorderly behavior shall be made upon substantial evidence. It shall not be necessary that criminal charges be brought to support a determination of disorderly behavior, nor shall the fact of dismissal or acquittals of such criminal charges operate as a bar to adverse license action under this article.
(g) Remedies not exclusive. The criminal and civil remedies provided in this article are not exclusive, and the city council may take any action with respect to a licensee, a tenant, occupant or the licensed premises as is authorized by other ordinances or the laws of the state.
