On May 15, 2007, the Board of St. Mary's County Commissioners adopted the Environmental and Solid Waste Fee (Ordinance No. 2007-04) payable by persons who own improved residential property in St. Mary's County. “Residential property” is all improved property that is residentially zoned and contains one or more dwelling units. This includes, but is not limited to: a single-family home, a duplex, a triplex, a four-plex, an apartment building, a mobile home and/or trailer, a condominium, a town house, a cooperative housing unit, or a residential building on a perma-lease. The established annual rate for this fee is $94.68 per dwelling unit. Written requests for appeal of this fee shall be made to the Office of the County Treasurer and must be received by December 31 of the year in which it is due. An appeal may only be granted under the following circumstances: administrative or clerical errors, number of units inaccurate or a dwelling unit was (1) uninhabitable, or (2) was demolished as of January 2 of the year in which the fee is due. The burden is on the property owner to provide convincing evidence to the County in order to have the appeal considered.
