How to Add a Pool to Your Hamptons Home Without Violating Zoning Codes

What Every Homeowner Needs to Know Before Breaking Ground

A backyard pool in the Hamptons? Yes, please. But before you start envisioning summer swims and poolside spritzes, there’s one important step that can’t be skipped: making sure your dream pool doesn’t violate local zoning codes.

In Suffolk County, and especially in municipalities like East Hampton, Southampton, Sag Harbor, and beyond, adding a pool isn’t as simple as digging a hole and filling it with water. Zoning laws, environmental regulations, and building codes can make the process surprisingly complicated.

Here’s how to add a pool the right way, and avoid expensive mistakes along the way.

Step 1: Know Your Property’s Zoning Restrictions

Zoning codes vary by township, and they determine where you can build a pool and how big it can be. Important factors include:

• Setback requirements (how far the pool must be from property lines, buildings, and roads)

• Lot coverage limits (how much of your lot can be covered by structures, including patios and pools)

• Maximum pool area and fence regulations

• Proximity to wetlands or conservation areas

• Height restrictions for features like pool houses or retaining walls

Don’t assume your neighbor’s pool is a model to copy—every property is unique.

Step 2: Get a Current Survey and Site Plan

Before applying for permits, you’ll need an up-to-date property survey showing the layout of your land, existing structures, and proposed pool location. This is critical for showing zoning officials how your pool will comply with local code.

In many cases, you’ll also need:

• Grading and drainage plans

• Landscaping plans

• Elevation drawings if the pool is elevated or features retaining walls

Step 3: Apply for the Proper Permits

To legally build a pool in the Hamptons, you’ll need to obtain one or more of the following:

• Building Permit

• Zoning Board of Appeals (ZBA) Approval, if you need a variance

• Wetlands Permit, if you’re in a designated environmental area

• Board of Health approval (especially if septic systems are involved)

• Fence or Barrier Permit, depending on your township

Don’t forget—timelines for permit approvals can vary, especially in summer. Apply early.

Step 4: Avoid Common Pitfalls

The most common zoning violations we see with pool projects?

• Building too close to a property line

• Overbuilding lot coverage limits

• Failing to account for septic location or setbacks

• Ignoring restrictions near wetlands or dune zones

• Missing or incorrect fencing and safety barriers

Any of these can delay your project, or worse, result in a stop work order or required removal.
