Harrison House
Why it's listed
Harrison House is a modest single-story wood frame farmhouse at 27832 Ortega Highway in San Juan Capistrano, built around 1906. It sits on a low rise north of San Juan Creek, on a lot reduced to 0.18 acre, and was one of the ranch houses up the valley from the mission settlement. The house has a hipped roof, a dormer over the front door, a porch along the front and west sides, and a central hall plan. Its single-wall clapboard construction was a method common on the Southern California coast, here adapted to a California bungalow. Old photographs show several similar buildings in town, but this is the only one left. The ranch passed through several owners, including Andrew McNally and later John J. Harrison, who lived there 36 years and grew oranges. The house was listed as a rare survivor of its type, a reminder of the area's farming past, and a companion to the adjacent Parra Adobe. The city owns it and planned its restoration.
Significance in brief: The nomination argues the house represents a once-common architectural style that is now rare, with single-wall construction typical of coastal Southern California. It is also a reminder of the community's agricultural heritage, which lasted from 1776 to about 1970. It adds to the setting of the neighboring Parra Adobe, which is already listed.

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.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
