The original Carbo House, constructed in 1914, was destroyed by fire in 1931. The present building, erected on a larger lot that incorporates the original lot to the south, is one of a few boarding houses remaining from the resort era and the only example that has not been significantly altered. The two-story frame building employs a low-pitched hipped roof with exposed rafter tails and wraparound porches across both stories. Exterior stairways are located within the porches along the sides of the building.
