Oyster Bay building permits start with the town portal
Oyster Bay property work should start with the town building page and portal before a contractor treats the job as simple.

In Oyster Bay, a fence, deck, interior renovation, generator, dormer, or change of use should begin with the town building route rather than a contractor’s guess. The town posts Building Division information and a building portal for permit activity. Owners should check whether the job needs a permit and which documents, inspections, and certificates close the file. Buyers can use the same portal to ask about an open permit or finished basement before closing.
Use the Oyster Bay Building Division page and building portal for the property and project involved. Save the application or permit number, address, and any portal receipt or notice so the town can reopen the same file.
