A historic mixed-use building in downtown San Diego’s Gaslamp Quarter has been sold to an undisclosed buyer for nearly $6.3 million.

The George Hill Building, 527-545 F St, was sold by Hill SD LLC, a subsidiary of Viewpoint Equities Inc. with Gregg Seaman as the managing partner.

The 15,639 square-foot building was built in 1897 on a 5,000 square foot corner lot at Sixth Avenue and F Street.

It replaced the landmark Horton’s Hall, which was partially destroyed by fire.

The building was originally designed for five storerooms on the first floor, and thirty offices on the upper floors.

The San Diego Normal School, now San Diego State University, once leased space on the upper floors.

The new owner plans to renovate the top two floors of the three-story building into creative office space.

The bottom is leased long-term to a restaurant.

Representing the seller from Marcus & Millichap was Nick Totah, first vice president of investments at The Totah Group of the firm’s San Diego office.
