The form states it is not architecturally significant, but its present appearance dates to the Holt family's residency and reflects their growing affluence. A reviewer noted it meets criterion B.","narrative":"This two-story house at 548 Park Street in Stockton has a basic structure dating to 1869. Later additions gave it a highly irregular plan, including a Colonial Revival entry commissioned by Mrs. Benjamin Holt in 1929, a sleeping porch added around 1917, a large east porch with Doric columns, and a two-story rear addition. A hipped-roof garage built around 1904 stands to the south, and old palms from the Holt period remain on the grounds. The house is important mainly because Benjamin Holt (1849-1920) lived here from 1899 to 1920. Holt held more than one hundred patents and developed the track-type Caterpillar tractor, testing it in 1904 and bringing it to mass production at a plant a few blocks away. Tractors of this type hauled artillery and supplies in World War I. The house is not considered architecturally distinguished, but its appearance reflects the tastes and rising wealth of the Holt family.","period_of_significance":"1800-1899 and 1900- (specific dates given as 1869, with numerous alterations); Holt residency 1899-1920","architect_builder":null,"architectural_style":"Colonial Revival entry on an altered, irregular-plan house; not stated as a single style","criteria":["B"],"status_note":"Listed as occupied, in good condition, on its original site and altered; the form notes the rear doorway is severely damaged and must be replaced.
