Peebles Corp. is revising its plan to convert Center City's former Family Court building into a hotel after an earlier proposal by the developer failed to qualify for support under the Federal Historic Preservation Tax Incentives program.

The National Park Service, which rejected the plan in May, is working with Peebles and the Philadelphia Industrial Development Corp. (PIDC) on changes to the project "in response to our comments for resubmission," agency spokesman Jeffrey G. Olson said in an email Monday. 

The National Park Service ruled in May that the Coral Gables, Fla.-based developer's plan for the 75-year-old city-owned building at at 1801 Vine St. would "severely downgrade" its historic character, disqualifying it for the tax credit.

Peebles has until the end of December to secure approvals for the credit, an extension from the Nov. 30 deadline it previously had as part of its development deal with the city, PIDC president John Grady said in an email. 

Peebles spokeswoman Nicole D. Goldberg did not respond to an email asking about efforts surrounding the tax credit and branding plans for the hotel.
