The city is currently developing a bid to purchase the 380 Hamilton Avenue structure that was built in 1932 and is listed on the National Registry of Historic Places.
The anticipated deadline to submit an offer is October 17.
The city notes building specification innacuracies in letter sent to CBRE, the brokerage company for the property sale, and the United States Postal Service.
Palo Alto officials say building specifications listed by the seller are inconsistent with research commissioned by the city.
City officials say the property, which is listed on http://www.uspspropertiesforsale.com/ , misrepresents the structure's square footage by about 30 percent and the land size by more than 1,000 square feet.
“The property summary listed on the USPS site indicates the 'rentable' square footage as 33,848 square feet,” a statement on the city's website said.
“In fact, the existing square footage as calculated by the historic architect and used in the city’s appraisal is 22,182 square feet. In addition, the listing shows the land size as 33,750 square feet, but the City’s parcel map shows the lot size to be 32,700 square feet.”
