(A)   Personal liability. The owner of premises on which a nuisance has been abated by the city or a person who has caused a public nuisance on a property not owned by that person shall be personally liable for the cost to the city of the abatement, including administrative costs. As soon as the work has been completed and the cost determined, the City Clerk or other official shall prepare a bill for the cost and mail it to the owner. Thereupon the amount shall be immediately due and payable at the office of the City Clerk.
   (B)   Assessment. After notice and hearing as provided in Minn. Stat. § 429.061, as it may be amended from time to time, if the nuisance is a public health or safety hazard on private property, the City Clerk shall list the total unpaid charges along with all other charges as well as other charges for current services to be assessed under Minn. Stat. § 429.101, as it may be amended from time to time, against each separate lot or parcel to which the charges are attributable.
   (C)   Overhead charge; civil penalties. When the city has abated a public nuisance maintained by any owner of real property, an additional civil penalty of up to 50% of the cost of abatement will be added to the amount of expenses and charged to the owner for each subsequent nuisance that is abated by the city within two consecutive calendar years concerning real property owned by the same person. The civil penalty will be imposed without regard to whether the nuisances abated by the city involved the same real property or are of the same character.
