Irwin Brothers Store
Why it's listed
Built in stages between 1823 and about 1850 from locally quarried blue limestone, this nine-bay, two-story building sits at the corner of Route 180 and Woodward Road in Stone Mills. The original three-bay core has a north-south gable roof, flanked by a west wing of about 1837 and an east wing of about 1850. A wooden carriage barn from the 1880s sits to the southwest. The building began as a store and tavern, served as a stagecoach halfway house, and later housed a Masonic lodge on the second floor from 1851 to 1867 and the community post office. William B. Irwin bought it in 1875, and the Irwin family ran the general store until 1954. Over time it also served as a telegraph office, telephone office and gas station. Original moldings, doors, hardware and three fireplaces survive inside, though the porches were removed after 1948. A local historical society bought it in 1978 to convert it into a rural museum.
Significance in brief: The nomination argues the store is an early and distinctive example of limestone masonry construction in the Stone Mills area and one of the earliest surviving stone buildings there. It also played a prominent role in the nineteenth- and twentieth-century development of the hamlet as a store, tavern, meeting place, post office and information center. It retains integrity of design, materials and craftsmanship.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
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.
