Cocktail parties in Water Mill: what's different here
Estates on Mecox Bay and the ocean in the most expensive ZIP code on the South Fork, the Parrish Art Museum on Montauk Highway for a party of 300, farm fields and the two working mills, and the Halsey House of 1683 for the history.
Water Mill hosts cocktail parties on estate lawns with a tent for the bar and on village porches for thirty; the difference is whether the caterer brings a kitchen trailer or a hot box, and we choose the company by which house it is.
Parties here follow the Town of Southampton, as its code is summarised: 48 hours’ notice to the Fire Marshal above 50 guests, a tent permit from the Fire Prevention Office for anything over 200 square feet, no tents in the driveway, and the Town named on the liability policy with liquor cover if the bar is open. Water Mill is a hamlet of the Town of Southampton with 2,506 people at the 2020 Census and a median home price of $5,885,000 in 2024, the third most expensive ZIP code in the country; the Town’s housing plan counts more than 60% of its houses as seasonal.
Event and tent permits in Water Mill run through the Town of Southampton Fire Prevention Office in Hampton Bays (special events and tents); the caterer we put you in touch with has worked with them before, and this page says when a permit is likely to apply.

FAQ
Cocktail parties questions
How many servers and bartenders do I need for 100 guests?
For a plated dinner, 8–10 servers (one per 10–12 guests, one per 8 for a complex menu) and two bartenders (one per 50); for a buffet, 4–5 servers (one per 20–25) and the same two bartenders; for a standing cocktail party, one server per 20–25 and one bartender per 50, one per 40 on a hot night. In the kitchen, one chef per 40 covers plated, one per 50 buffet, one per 60 for cocktail service, with a head chef above 75 guests. One East Hampton caterer publishes its own version: one staff member per 10–12 guests, a four-person minimum and five-hour minimum shifts. A New York staffing agency lists waitstaff at $27 an hour, bartenders at $30, a captain at $35 and a chef at $50, with five-hour minimums.
What is the service charge on a Hamptons catering proposal, and is it a tip?
Usually not. The administrative or service fee, 15–25% across the market and 20% at two named Hamptons caterers, covers coordination, insurance, kitchen staff and vehicles; one Bridgehampton caterer says in writing that it is not a gratuity for the service staff. Gratuity is a separate line: one East Hampton caterer adds 15%, another leaves it discretionary. New York taxes the whole catering charge, and a mandatory gratuity escapes the 8.75% Suffolk sales tax only if it is separately stated, called a gratuity, and paid entirely to the staff; a service charge by any other name is taxed. If your proposal has a service charge and no gratuity line, ask what the staff receive.
How does Sagaponack Catering Co. work?
You tell us about the event once: what it is, when, roughly how many, where in the Hamptons, and the style if you have a preference. We put you in touch with one caterer who does that kind of event at that size in that town, insured and cooking from a permitted kitchen, and they call you within one business day. From there it is their tasting, their proposal, their contract and their staff. It is free for hosts; participating caterers pay us a referral fee for the introduction. We are not a caterer and we do not sell your details; the one company we send you to is the only one that gets your number. We cover 9 South Fork towns and 6 kinds of events.
