Technically, yes. The McKinney Historic Preservation Ordinance does not regulate paint colors in the residential area of the Historic Overlay District. However, it is recommended that you don’t paint unpainted stucco or masonry (brick or stone). Should you want to remove paint from masonry, the Historic Preservation Office recommends that you not use abrasives, such as sandblasting or any other blasting method, but instead, consider a chemical paint remover.
Paint colors in the commercial area of the Historic Overlay District do require approval when changing colors. A Certificate of Appropriateness must be obtained for this prior to completing the work.
