Temporary signage serves a legitimate practical purpose and has little or no lasting impact on the character of historic property. HPO shall apply the criteria in this section when reviewing temporary signs under the authority delegated in § 320 of this subtitle.
HPO shall routinely approve temporary signage to be installed for less than ninety (90) days or that is less than twenty square feet (20 sq. ft.) in size, provided it is installed in a manner that does not cause permanent damage to historic property.
HPO shall review a temporary sign to be installed for more than ninety (90) days or that is more than twenty square feet (20 sq. ft.) in size according to the standards and criteria for permanent signs. HPO may grant greater flexibility in terms of size, placement, type, shape, material, and copy, provided that the sign is installed in a manner that does not cause permanent damage to historic property.
A temporary sign may be denied if it is plainly and unnecessarily incompatible with the architecture and characteristics of the building, site, or district, or if its installation is likely to cause permanent damage to historic property.
The permit application for a temporary sign shall indicate the period of time during which the sign is to be displayed. The permit for a temporary sign is not valid beyond its stated duration.
