Southampton, NY Home Business: Customer Traffic Restrictions (2026)

Section 330-5 defines HOME PROFESSIONAL OFFICE narrowly: the office or studio of a resident physician, surgeon, dentist or other licensed healer, lawyer, architect, artist, real estate or insurance broker or agent, or teacher, restricted so that no more than two persons who are not family members may be employed by or associated with the office. If a third non-family person joins, the use is no longer permitted as a home professional office at all and can continue only if the Zoning Board of Appeals grants a use variance treating it as a commercial office.

Each lot is limited to one such office; a second one on the same lot faces the same prohibition and variance requirement. The office may occupy no more than half of one floor of the main dwelling, or half the minimum first-floor area if placed in an accessory structure, and it must produce no external evidence of business use beyond an announcement sign. Because client visits are not capped by a headcount, § 330-95's Schedule of Off-Street Parking Space Requirements does the practical work of limiting how much customer and client traffic a home occupation or home professional office can handle: it requires, on top of the parking already required for the dwelling itself, two spaces for the first 400 square feet devoted to the business use, one additional space for every extra 150 square feet or fraction of it, and one more space for every employee who is not a family member.
