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.","narrative":"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.","period_of_significance":"1900- (probably circa 1906)","architect_builder":null,"architectural_style":"Vernacular single-wall construction California bungalow with slight Craftsman details","criteria":[],"status_note":"Vacant and deteriorated at the time of nomination, with windows and doors boarded after vandalism.
