A group of Jewelers Row property owners and merchants have teamed with preservationists to appeal the Philadelphia Department of Licenses and Inspections' approval of plans for a 16-story condo tower on the venerable Sansom Street shopping district.

L&I inspectors should not have issued demolition permits for the project because relevant notices had not been posted to all the properties that developer Toll Bros. is seeking to clear, Paul Steinke, executive director of the Preservation Alliance for Greater Philadelphia, said this week.

The developer also failed  to identify the buildings' owners in its zoning permit paperwork as required, said Steinke, whose group is among those who filed appeal applications on Aug. 26.

The Zoning Board of Adjustment will likely hear the appeals within 45 days, Steinke said. L&I spokeswoman Karen Guss said the department would abide by the board's decision. 

Tim Spreitzer, a spokesman for the Toll unit planning the development, Toll Bros. City Living, said the company is aware of the appeal and remains "confident in our ability to proceed under the by-right zoning status of this project."
