NEW YORK (CBSNewYork/AP) -- Mayor Michael Bloomberg has previously said the mayor should not live in Gracie Mansion, but candidates Bill de Blasio and Joe Lhota have every intention of doing so.
The mansion has sat vacant for 12 years, as Mayor Bloomberg instead decided to live in his luxurious Upper East Side town house.
Although he has never spent a night there, Bloomberg poured millions into a sweeping renovation of the graceful Federal-style mansion, which sits in a Manhattan park that overlooks the powerful confluence of the East River and the Long Island Sound.
But with Bloomberg leaving office at year's end, Gracie Mansion, which has been open to the public as a museum and used to host city receptions, will again become a private residence, a legacy that is etched right in its glass.
Hidden behind a curtain in one of the mansion's front rooms is a small window that has been the victim of loving graffiti done by children of former mayors. Then-12-year-old Caroline Giuliani, daughter of Rudy, carved ``Caroline 2001'' into the window before moving out, following the example of John Lindsay's daughter Margaret, who etched her name in 1965.
Could "Dante" or "Chiara" (de Blasio) or "Kathryn" (Lhota) be next?
The major mayoral candidates have all indicated they would likely move into the mansion if elected.
Public Advocate Bill de Blasio, the Democratic nominee who has a commanding lead in the polls, will not comment on the mansion these days, saying he does not want to appear overconfident of victory. But at a candidate forum this year, he noted that the Brooklyn home he shares with his wife and two children gets crowded and ``Gracie obviously has a little more space.''
Republican Joe Lhota has said he would live there with his family but has allowed that he might occasionally spend a weekend night back in his Brooklyn home.
Gracie Mansion, which is painted in its original yellow with green shutters and white trim, has changed considerably since the Giuliani family departed in December 2001. (The mayor himself had moved out earlier that year after separating from his wife.) Soon after taking office, Bloomberg, under the guise of being an anonymous donor, gave $7 million to refurbish the home's porches, stairs and bathrooms.
``The place was falling apart,'' said Susan Danilow, executive director of the nonprofit Gracie Mansion Conservancy. ``Mayor Bloomberg may not have lived there, but he really loves the home.''
The kitchen was redone last year at a cost of $1.25 million, money that was raised by the conservancy. The nonprofit organization was established in 1981 by Mayor Ed Koch to preserve the mansion, which sits on the site of another home that was commandeered by George Washington during the Revolutionary War.
That home was destroyed by British cannonballs, one of which was found a century later during construction work. The 12.5-pound ball now sits on a mantle in the home.
The current structure was built in 1799 by a merchant named Archibald Gracie in a location that, at the time, was in the countryside more than 5 miles north of the fledgling New York City. It changed hands several times until it was seized by the city in 1896 after the owner failed to pay taxes.
It briefly housed the Museum of the City of New York, but in 1942, powerful Parks Commissioner Robert Moses designated it the official residence of the mayor, prompting Fiorello LaGuardia to move in. In 1966, the home nearly doubled in size thanks to an expansion.
The four-bedroom home, which Bloomberg uses for weekly meetings, has 12 full-time employees, including kitchen and gardening staff.
The bulk of the mansion's $1.7 million operating budget is picked up by the city, with additional costs paid by the conservancy. Because the mansion will likely become a full-time residence, the conservancy will be able to host fewer events at the home.
The home's downstairs features the kitchen, meeting rooms and a gigantic ballroom for events, while the upstairs is the living quarters. The home is dotted with antiques donated by some of the city's most prominent families, though the incoming mayor would be able to furnish it as he wishes.
That could prove useful since the four-post bed in the master suite appears far too short for de Blasio's 6-foot-5 frame.
``This is not just a historic home from the 18th century,'' Danilow said, ``but a home where history is still made.''
Last year, Bloomberg said he firmly believes mayors should not live at Gracie Mansion.
"Now [late ex-New York City mayor] Ed Koch, who I respect and love, he said 'It's a great house,' Bloomberg said in 2012. "It is a great house. I just disagree with him. It's a great house for everybody, not for one family."
The mayor said in 2012 he appreciates and takes pride in the fact that city agencies and non-profit organizations hold gatherings there.
"It should be used as we use it now," Bloomberg said in 2012. "There are events every day at Gracie Mansion throughout the whole house. If a mayor's family is living there, then most of that house -- a good half of it -- is just not available. If a mayor lives there, then what they're doing is costing this city a lot more money and depriving the rest of the city of one of the great facilities any city has."
