The Mayor and City Council of Baltimore City may amend or repeal zoning regulations and boundaries. If the purpose and effect of a proposed map amendment is to change the zoning classification of particular property, the City Council shall make findings of fact that address: population change; the availability of public facilities; present and future transportation patterns; compatibility with existing and proposed development for the area; the recommendations of the Baltimore City Planning Commission and the Board; and the relationship of the proposed amendment to Baltimore City’s plan. The City Council may grant the amendment to change the zoning classification based on a finding that there was: a substantial change in the character of the neighborhood where the property is located; or a mistake in the existing zoning classification. The City Council may not allow the filing of an application for a reclassification of a tract or parcel of land for which a reclassification has been denied by the City Council on the merits in the 12 months before the date of the application.
