Several Suffolk County towns have adopted floor area ratio, lot coverage, and bulk limits to curb mansionization, especially in the Hamptons. Limits are set at the town and village level, not by Suffolk County.
Suffolk County itself does not regulate residential bulk; mansionization controls are set by each of the ten towns and incorporated villages. East Hampton, Southampton, North Haven, Sag Harbor, and other East End jurisdictions have adopted floor area ratio caps, gross floor area limits, pyramid setback or sky-plane rules, and lot coverage maximums. Some towns require special review for new homes above set square footage thresholds. Builders must consult town zoning before design. Village rules often layer on top of town rules. Architectural review boards may have additional design standards in historic districts.
Zoning violations: town fines from two hundred fifty to ten thousand dollars per day, demolition orders, and stop-work pending compliance.
