Why it's listed

Port Jefferson Village Historic District occupies the hillside east of Port Jefferson Harbor on Long Island's north shore, along with part of East Main Street. It holds 98 contributing and 58 non-contributing resources, mainly modest wood-frame houses on small lots along narrow, tree-lined streets. Most were built between the 1840s and 1870s in the Greek Revival or Italianate style, with a few earlier Federal houses and later Stick and Queen Anne examples. The neighborhood reflects the decades when shipbuilding drove the local economy. Larger houses of shipbuilders, captains and merchants stand among the plainer homes of ship carpenters, caulkers and mariners, and several shipbuilders' houses were sited to look down on the waterfront yards. East Main Street adds two-story commercial buildings and a small Congregational church. The adjoining Bayles Shipyard is separately listed. Some houses were counted as contributing despite alterations because of their ties to the maritime trades.

What listing means for this property

This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
