How Much Do Building Permits Cost in the Hamptons?

Building in the Hamptons? Here’s What It Might Cost

The cost of obtaining a building permit in the Hamptons can range from a few hundred dollars to tens of thousands, depending on the project size, scope, and location. Every town and village has its own fee structure, and in some cases, multiple permits are needed for one project — such as separate fees for zoning, building, wetlands, and architectural review.

Common Permit Fee Ranges

Here’s a general idea of what you might expect:

• New Home Construction: $2,000 to $10,000+

• Renovations or Additions: $750 to $5,000

• Accessory Structures (pools, garages, decks): $250 to $2,000

• Demolition Permits: $150 to $1,000

• Wetlands or Natural Resources Permits: $500 to $3,500+

• Zoning Variance Applications: $500 to $1,000 (not including legal or survey costs)

Keep in mind: some villages calculate permit fees based on square footage or project value, which means even a small project can get expensive fast.

Additional Costs to Consider

• Certificate of Occupancy (CO) fees

• Inspection and re-inspection charges

• Plan review fees

• Refundable deposits or bonds

• Fees from outside consultants required by the town (e.g., engineering or environmental reviews)

If you’re building in a coastal area or flood zone, expect extra costs related to FEMA compliance, soil testing, or elevation certificates.

What Happens If You Build Without a Permit?

Trying to avoid the fee can cost you even more in the long run. Unpermitted work can lead to:

• Stop Work Orders

• Double permit fees as penalties

• Legal issues when selling your property

• Required demolition of non-compliant work
