Around 1790, Jacob Mabee built the inn as the last significant addition to the home. Originally a freestanding structure, it took advantage of increased traffic on the Mohawk River by accommodating travelers passing the farm's shores. Guests received home cooked food and ale, warmed themselves by the fireplace, and slept in a warm, dry garret for the night. The inn operated successfully for several decades and provided additional revenue for the family. After the Erie Canal opened in 1825 and diverted traffic away from the river, the inn ceased to be profitable, and the Mabee family converted it into living space. The building reflects prevailing Dutch building styles, while its enclosed fireplace shows English influence. Built during a time of cultural and historical transition, it underwent many transformations and came to represent change and adaptation at Mabee Farm and throughout the region.
