Charity began at home for this foundation — literally.

A small family nonprofit formed to benefit underprivileged kids used its funds to buy a $1.1 million home in Southampton — where its director lived, authorities said Tuesday.

Under the terms of a settlement with state Attorney General Eric Schneiderman, trustees for the Victor Perley Fund agreed to resign and reserve the group’s remaining assets of nearly $1 million solely for charitable purposes.

Former fund Chairman Richard Basini had paid just $1,000 a month to live in the 4-bedroom house even though the decadent digs rented out during peak beach season for 25 times as much.

The nonprofit launched a choir whose kids were supposed to benefit from the retreat, but they visited fewer than three times a year on day trips, officials said.

“My office has zero tolerance for trustees who use charitable assets for their own personal gain,” said Schneiderman.
