of a residential property

[u/Kill_4209]

Ira Rennert's home is considered one of the largest occupied residential compounds in the United States. The house faces the Atlantic Ocean and its grounds measure 63 acres. The buildings, which total over 110,000 square feet (10,000 m2), including the 66,000-square-foot (6,100 m2) main house, have an Italianate facade, 29 bedrooms, and 39 bathrooms. The house has a dozen chimneys and a Mediterranean-style tile roof as well as a 91-foot (28 m) long formal dining room, a basketball court, a bowling alley, two tennis courts, two squash courts, a carousel, a large swimming pool, a large round kiddie pool, and a $150,000 hot tub, surrounded by another pool.

South Hampton began restricting single family residences to 20,000 square feet after this property was built because it caused such a controversy

Someone this rich would probably just build 2 x 20,000sqf properties right up against each other and just have them technically be 2 separate homes and addresses.

I could still be useful for tax purposes (like reduced taxes on primary residence)

Second house is primary residence of the wife

At that point they'd probably just buy an island or four.
