Before You Break Ground
Every town in Nassau County requires permits before a single shovel hits the ground on a pool project. The requirements, setbacks, fees, and processing times vary significantly from town to town — and failing to understand them before you start can cause costly delays or force expensive changes mid-project.
Here's what every Nassau County homeowner needs to know.
Important: Permit requirements change periodically. Always verify current requirements directly with your town's Building Department before starting a project. The information below reflects general requirements as of 2025 and should be used as a starting point, not a definitive guide.
Connecticut State Requirements — Apply Everywhere
Regardless of which town you're in, New York state law sets baseline requirements for all residential pools:
- Fencing: All residential pools must be enclosed by a fence at least 48 inches high with self-latching, self-closing gates. This is non-negotiable and is inspected before the pool can be used.
- Electrical: All pool electrical work must be performed by a licensed electrician and inspected separately from the pool permit.
- Setbacks: Most towns require pools to be set back at least 10–15 feet from property lines, though this varies by municipality.
- Health Department: In towns with older septic systems, Health Department approval may be required if the pool is within a certain distance of the system.
Key Towns at a Glance
Great Neck
Great Neck has some of the most thorough permitting requirements in the county. In addition to a standard building permit, most pool projects require zoning approval. Setback requirements are strict — typically 15–25 feet from property lines — and the town pays close attention to drainage and environmental impact.
Coastal and waterfront properties face additional review. The Inland Wetlands & Watercourses Agency review may be required for properties near water bodies.
Typical processing time: 4–8 weeks
Rye
Rye requires a building permit from the Building Department. A detailed plot plan showing the pool's location relative to all structures, property lines, and easements is required at submission. The town also requires a survey in most cases.
Inland Wetlands Commission review may be required depending on proximity to water features on or near the property.
Typical processing time: 3–6 weeks
Harrison
Building permit required from Harrison's Building Department. If the pool is within a certain distance of a septic system, Health Department approval is required before the building permit will be issued. Setbacks from property lines are standard at 10–15 feet.
Typical processing time: 3–5 weeks
Larchmont
Larchmont requires both a zoning permit and a building permit for most pool projects. The town is particularly attentive to setbacks from wetlands and watercourses — important if your property is near a stream, pond, or marsh. The Inland Wetlands Commission review can add significant time to the process.
Typical processing time: 4–6 weeks
Chappaqua
Building permit required. Inland Wetlands Commission review may be triggered depending on the property's proximity to water. Chappaqua has a relatively straightforward process compared to some neighboring towns, but the wetlands review can add 3–4 weeks if it applies to your property.
Typical processing time: 3–5 weeks
Bedford
Building permit required. Bedford's rocky terrain — common throughout the town — may require additional structural engineering documentation depending on site conditions. This is worth discussing with your builder early, as rocky excavation can affect both timeline and cost significantly.
Typical processing time: 3–5 weeks
White Plains
Building permit required. White Plains's process is generally straightforward. Properties near Long Island Sound or the Ash Creek area may face additional review. Standard setbacks and fencing requirements apply.
Typical processing time: 3–5 weeks
Yonkers & New Rochelle
Both cities require building permits. The more urban nature of these municipalities means smaller lots and tighter setback challenges are common. Processing times can be longer during busy seasons due to higher permit volume. Budget extra time if your project is in either city.
Typical processing time: 4–8 weeks
Tarrytown, Ardsley & Dobbs Ferry
These smaller, more rural towns have their own Building Departments with individual requirements. Inland Wetlands review is common given the prevalence of wetlands and water features throughout these towns. Processing times are generally reasonable but can vary based on seasonal volume.
Typical processing time: 3–6 weeks
What a Good Builder Handles for You
One of the most important reasons to work with an experienced local pool builder is permit expertise. A builder who has worked extensively in Nassau County knows the local inspectors, understands the common sticking points in each town, and knows how to prepare a permit application that moves through the process efficiently.
A reputable builder will:
- Pull all required permits on your behalf
- Prepare and submit all required documentation
- Coordinate any required agency reviews (Inland Wetlands, Health Department, Zoning)
- Schedule and manage all required inspections
- Handle any permit amendments if the project scope changes
If a builder asks you to pull permits yourself, consider that a significant red flag.
Timeline Planning: Start Earlier Than You Think
If you want to swim in your new pool next summer, you need to be thinking about this now — not in spring. Here's a realistic timeline working backward from a July 4th swim date:
- Now–February: Select your builder, finalize design, submit permit application
- March–April: Permit approval received, break ground
- April–June: Construction (3–6 months for gunite, 4–8 weeks for fiberglass)
- Late June–July: Final inspections, pool fill, ready to swim
Miss the February window and you're likely looking at a fall opening at best, or next summer at worst. The best builders in Nassau County book up fast — often 6–12 months in advance.
