South Yarmouth/Bass River Historic District
Also known as: Southside
Why it's listed
South Yarmouth/Bass River is a linear village district of roughly 108 acres in the southeastern corner of Yarmouth, Massachusetts, running along River Street, Old Main Street and North Main Street beside Bass River. It rose to prominence in the late 18th century through coastal and deep sea shipping, whaling, shipbuilding, ropemaking, saltmaking and magnesia production, then shifted toward summer tourism as those trades declined. Its character rests on shingled, 1 1/2-story Cape Cod cottages in half, three-quarter and full forms, dating from the 18th through 20th centuries. Larger Federal and Greek Revival houses, some with Italianate, Gothic Revival, Queen Anne or Stick detail, belonged to wealthy mariners and saltmakers. Churches, a school, a bank and a few shops are interspersed. Because Route 28 bypassed Main Street rather than widening it, the area avoided the commercial strip development common elsewhere on the Cape's south side, and few intrusions disturb its historic appearance.
Significance in brief: The district is an unusually well-preserved village of houses, institutions and shops that grew from late 18th-century maritime industries and later turned to summer tourism. It offers a thorough survey of the Cape Cod cottage house type alongside Federal, Greek Revival, Gothic Revival, Italianate, Second Empire, Stick, Queen Anne and Craftsman buildings. Bypassing of Main Street by Route 28 spared it the strip development that damaged other Cape southside areas.

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).
