2020 Home Renovation Costs Per Square Foot in the Hamptons

by Carol Wang

A cost breakdown on materials, labor, and permits for your home remodel

The Hamptons…the mere mention conjures up poolside luxury and endless summer. But what’s it really like to live—and renovate—there? If you’re considering buying a home in the East End to renovate, there are a few things you should know. We’ve done the homework, so read on to get a sense of what is involved in a Hamptons renovation. Keep in mind that all renovations are unique and that many variables factor into the equation.

Sweeten, a free service matching renovators with vetted general contractors, has compiled a general guide to costs across the Hamptons, focusing on four renovation categories—cost per square foot, kitchen, bathroom, and permits. It’s worth noting that every professional contractor will want to have a detailed chat and inspection of your home before developing an estimate specific to your needs and wants.

Here’s a breakdown of typical starting costs compiled from Sweeten renovations and Remodeling’s Cost vs. Value report.

  • Full home renovation: Starting at $100 per square foot (psf) with stock materials; high-end properties start at $250+ psf
  • Low-end kitchen remodel: $25,000 for under 100 square feet
  • Mid-range kitchen remodel: $40,000—$75,000
  • High-end kitchen remodel: $75,000+
  • Low-end bath remodel: $20,000
  • Mid-range bath remodel: $25,000—$40,000
  • High-end bath remodel: $40,000—$100,000
  • Basement remodel: $25,000—$100,000

A quick clarification: when referring to the Hamptons, we are talking about the Town of Southampton and the Town of East Hampton, which together comprise many hamlets and villages. Hamlets such as Westhampton, East Quogue, or Hampton Bays lie within the boundaries of the town of Southampton, while the villages of Amagansett and East Hampton are within the administrative boundaries of the town of East Hampton. This means that any building permits you file (discussed below) will be with the offices of the towns of Southampton or East Hampton.

There is a season for everything, but especially so in the Hamptons. Sweeten architect Andrew has a word of wisdom for would-be renovators: “The time of year is really significant. There is a big push before summer, and everyone is very busy. If you are planning a renovation, don’t plan it in the spring; it’ll be more expensive and you’ll be competing against everyone else for the best contractors and subcontractors. If possible, get the design process started in the fall and do the work in the winter, when it’s the low season.”

What a home remodel costs per square foot

In speaking with experts who work in both New York City and the Hamptons, the general consensus is that costs per square foot are essentially the same in both locales. As we point out in our cost guide to Westchester County, proximity to Manhattan dictates both the buyer demographic as well as real estate values. This, in turn, is reflected in the cost of renovations. As Sweeten contractor Eric points out, however, there are subtle differences between the villages and hamlets, with East Hampton being the priciest. At Sweeten, we’ve seen projects starting at $100 per square foot with stock materials, while high-end properties start at $250+ psf.

While renovation costs per square foot will vary depending on whether it is a gut or non-gut, and the level of finishes and customization you require, Eric tells us that there is a starting point of $150 psf for renovations with stock materials. Luxury waterfront properties, however, start at $500 psf for high-end renovations and can exceed $1,000 depending on the level of complexity and finishes. (See Budget Basics: Renovation Costs Per Square Foot, where we outline three levels of renovation.)

Additionally, cost increases over the past year have also pushed baseline budgets upwards: the price of fuel has gone up, as has general liability insurance, said Sweeten contractor Eric. “Building materials are also up from last year because of supply and demand; everyone is renovating! And when homeowners are renovating, the cost for electricians and plumbers and other subs increase, because they can pick and choose between most profitable jobs. They will charge more now for smaller jobs like a single kitchen or bath.”

Costs for a kitchen renovation

  • Low-end kitchen: Most Sweeten kitchen remodels in the budget range average $25,000 for under 100 square feet with budget-friendly finishes from retailers such as Home Depot. 
  • Mid-range kitchen: Most Sweeten projects in the mid-range can fall between $40,000—$75,000. In Sweeten contractor John‘s experience, he cites a mid-range kitchen could average in the $75,000 range. Ariel Okin, an interior designer who works in the Hamptons, tells us: “Kitchen gut renovations can range from $40,000—$150,000 depending on the level of work the client wants, and the same goes for baths. Square footage, scope of work, and estimated amount of time it will take to complete the job are all major considerations that go into pricing out the project.”
  • High-end kitchen: At Sweeten, we’ve seen projects cost start at $75,000 for high-end finishes. According to Remodeling’s Cost vs. Value 2019 Report, a major upscale kitchen remodel averages $155,309 in New York or $777 per square foot. This is based on a 200-square-foot kitchen with top-of-the-line custom cabinets, stone countertops, imported tile backsplash, built-in refrigerator, microwave, commercial-grade cooktop, and vent hood, as well as all new lighting and wood floors.

Sweeten contractor John estimates that a high-end kitchen in the Hamptons will start at $150,000 and up.

Costs for a bathroom renovation

  • Low-end bathroom remodel: At Sweeten, we’ve seen projects begin at $20,000. John quotes a three-piece (shower, sink, and toilet) project to average out to about $35,000 for a 5’ x 8’ space with budget-friendly finishes.
  • Mid-range bathroom remodel: Sweeten has completed bathroom renovations between $25,000—$40,000 in the mid-range that covers about 100 square feet.
  • High-end bathroom remodel: At the high-end range, Sweeten renovations that consist of three-pieces can cost between $40,000—$60,000. A high-end master suite remodel consisting of 4-5 pieces including a shower, double sink, bathtub, and toilet costs between $60,000—$100,000. According to Remodeling’s Cost vs. Value 2019 Report, an upscale bathroom remodel averages $84,704 in New York or $847 psf. This is based on expanding an existing 35-square-foot bathroom to 100 square feet, relocating all fixtures, and installing a new shower with a frameless glass enclosure, freestanding soaker tub with high-end faucets, stone counters with dual sinks, one-piece toilet, and a humidistat-controlled exhaust fan.

Sweeten contractor John estimates that a high-end master bath renovation would run about $100,000 on average.

Costs for a basement renovation

At Sweeten, we’ve seen basement remodels budgeted at $100—$150 psf or $25,000 for a simple coat of paint. A gut renovation would cost $50,000—$100,000 which could include plumbing, electrical, an entertainment center, appliances, closets, and with possible walls going up or down. An average basement conversion in the New York area is $75,000, according to the Cost vs. Value report. The project for this size budget includes a 20′ × 30′  foot room and a 5′ × 8′ foot bathroom with a shower and bar area as well as insulation and laminate flooring. This sample project works out to $117 psf.

What to know about permits in the Hamptons

Permits are a big part of the renovation process in Hamptons towns. While expediters are not regularly used there, the process can involve two types of experts not usually called upon in renovation projects elsewhere.

  • Environmental consultants can assist homeowners and architects in parsing land use regulations, coastal environmental planning, and acquisition of related permits. Given the delicate ecosystems and the proliferation of wetlands and sand dunes along the coasts, these consultants are crucial to navigating this aspect of the permit process. They are also able to answer questions about whether you can expand the footprint of a house or add a dock, etc. They typically charge by the hour (ranging from $250-350/hour, with a minimum project fee). For an initial site inspection and report, some offer a flat rate fee around $1,500 to inspect the property and produce a report.
  • Local attorneys who are well-versed in the zoning codes of the particular town in question can help navigate the process. Sweeten architect Andrew tells us that East Hampton recently changed some of its codes and a local attorney assisted him and his client in liaising with the town office on a debated matter of allowable square footage. Attorneys’ fees vary; a local real estate agent can provide recommendations.

Keeping up with local regulations and requirements

While the town offices may be small and provide a more personal interaction, as Sweeten architect Andrew relates, don’t mistake that casual air for a casual approach to enforcing regulations. For example, certain neighborhoods in the Hamptons won’t allow work on weekends, or after a certain time in the high season. Recently, there have also been more attempts to limit the square footage on properties, as well as accessory structures that may be used as rental properties. There are also stringent regulations at the town, state, and federal levels that will affect your renovation, depending on how large it is.

Andrew also notes that while it’s important to understand what the current code is, you should also try to find out what is “in the works in terms of changes to the code. You can start a project, and spend over a year in the design process, and the code can change. You should try to find out via word-of-mouth or at town hall about what big changes are on the horizon.”

One relatively recent development has been a change in the energy conservation requirements in East Hampton, for example. Andrew notes that he is dealing with this on a current project, where they will now need to hire someone who is certified to complete the HERS rating, which will cost between $1,000—$2,000. They may also need to use different building components to achieve better insulation and R-value required today.

The Town of Southampton provides this handy Building Permit Application Checklist for residential interior renovations (note that different fees and applications are required for other types of construction).
