How to get a building permit in the Town of Oyster Bay

1. Check whether the work needs a permit

Pools, fences over four feet, raised decks, sheds over 100 square feet, retaining walls and sewers, drywells and cesspools are on the Town’s list.

2. Zoning relief first

If the Zoning Board of Appeals must approve the project, send notice to surrounding property owners and post a sign on the property, then go to the Building Division after an approval.

3. Quick jobs: portal or same day

Common “Fast Order” or “Instant” permits go through the Building Division Online Portal. Property owners and expeditors register an account first; contractors send the Contractor Activation Form to planninganddevelopment@oysterbay-ny.gov.

4. Other work: apply at the Building Division

Get the application at 74 Audrey Ave or Town Hall South. New construction generally needs a copy of the survey and two copies of the construction plans.

5. Highway permits

Sidewalk, curb, apron and roadway work needs its own Highway Operations permit.

Every permit carries an expiration date set by the Town of Oyster Bay, which may void a permit if work does not start in time; confirm the expiry on phased or delayed work. Permit validity in New York
