Morton Homestead
Why it's listed
Located at 100 Lincoln Avenue in Prospect Park, Delaware County, the Morton Homestead began as a Swedish-Finnish log cabin built in 1654 by Morton Mortonson, a Swedish settler. A second building of similar design was added in 1698, and both were originally one story. In the late 1790s the two structures were joined by stone walls and roofed over with clapboard, creating a second story. Further alterations to the upstairs room were made in 1835. The house contains late seventeenth-century furniture. The property stayed in the Morton family for generations, most notably John Morton (1725-1777), chairman of Pennsylvania's delegation to the convention that adopted the Declaration of Independence and a signer of that document. The homestead is regarded as a rare surviving example of the dwellings built by Pennsylvania's earliest settlers, and it was recognized for both its building type and its link to a prominent colonial family.
Significance in brief: The nomination argues the homestead is significant for its architecture, as it represents the type of dwelling built by the earliest settlers in Pennsylvania. It is also significant for its association with the Morton family, prominent in colonial Pennsylvania, notably John Morton, a signer of the Declaration of Independence.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
