ADU in the Hamptons (Long Island, New York): Hamptons (Southampton Town) 87 Old Riverhead Road, Hampton Bays, NY 11946 0.63 acres (~27,400 sq ft). This matters: Southampton Town requires a minimum 30,000 sq ft lot for an accessory apartment, or 20,000 sq ft if the property is in a Census-Designated Place with density under 500/sq mi — Hampton Bays IS a CDP and qualifies for the 20,000 sq ft floor. So this address actually clears the threshold, which is a great Terraformal moment ("we checked the CDP density data so you don't have to"). Owner-occupancy is required, and the ADU is capped at 35% of the principal dwelling's floor area or 1,000 sq ft, whichever is less.
