Dallas BBQ will be opening a 15,500-square-foot spread at “The Junction” by Brooklyn College.

The three-story building at 2145 Nostrand Ave. anchors the major intersection with Flatbush Avenue and Hillel Place. The current Flatbush Federal Savings Bank will relocate by the end of the year.

The asking rent was $700,000 per year for the triple net deal — which means building owner A&H Acquisitions, headed by Alex Adjmi, just collects the dough and lets the tenant take care of everything else, including taxes of about $110,000 per year, over the 20-year term.

Robert Greenstone of Greenstone Realty was the sole broker on the transaction. “Dallas BBQ has the menu, price point, service and decor package sorely missing in the boroughs — and we are very proud to have represented them in this important transaction,” said Greenstone.

Beanie Baby daddy Ty Warner has purchased one of the Four Seasons’ retail units for $12.05 million from Baccarat. In 1994, Baccarat owned a piece of land that became part of the Four Seasons Hotel. The condo declaration gave Baccarat the retail unit but included the right of first refusal by the hotel owner — now Warner — should there ever be a bona fide offer to buy it.

Apparently, Jeff Sutton and Jared Kushner teamed up and made a bona fide offer for the condo, which is occupied by the Brioni store — and Warner invoked his clause.

Documents show Baccarat first transferred the unit for $5 million from an internal entity to itself and then over to the Ty Warner entity for $12.05 million.

The agency responsible for settling taxpayer gripes about city property tax assessment is going to start charging $175 for a hearing. New rules state the Tax Commission will charge the fee for properties assessed at $2 million or more, and for single condo units if the building’s total tax assessment is over that number.

Owners can still file a free application to maintain their rights and those that waive the hearing won’t pay the fee.

In 2009, the agency reviewed 19,122 out of the 46,239 applications that were submitted with another 16,433 taking a pass at the hearing — meaning the understaffed hearing officers still had to prepare the cases.

Sources said the Office of Management and Budget calculated the fee will bring in $700,000 per year. The agency says the money will be used to help cover the costs of the hearing and “to improve the process by enhancing the technology and modernizing the hearing process.”

“The number won’t have a chilling effect but is an unnecessary burden,” said Joseph Strasburg, president of the Rent Stabilization Association, who added this is obviously a way to raise revenue.
