The House at 29 Mt. Vernon Street in Somerville, Massachusetts is a well-preserved Greek Revival cottage. The 1+1⁄2-story wood-frame house was built in the late 1840s, when Mt. Vernon Street was a site of significant development activity. The house is distinctive on the street, as most of the other houses are larger. This house features wide eaves, and a full pedimented gable end above a porch with Ionic columns. It has an elaborate front door surrounded, with framed paneling and pilasters.

The house was listed on the National Register of Historic Places in 1989.
