It reflects the early twentieth-century residential subdivision of North Quincy farmland. It is considered significant at the local level under Criteria A and C.","narrative":"Built in 1911 for Henry J. Grass at a cost of $4,500, this two-family house at 20 Sterling Street sits on a corner lot in Quincy's Montclair neighborhood. Grass was an active carpenter and developer who built several houses in the area and helped subdivide Montclair. The house is a Colonial Revival interpretation of the American Four-Square form, a popular choice for two-family dwellings in North Quincy during the 1910s. It has a granite foundation, clapboard walls, a hip roof with wide overhang and hip dormers, and two-story angular bay windows on the front and side. A balustraded porch with four columns over a latticed base fronts the house, and the door has sidelights. Windows are one-over-one sash. A 1920s two-car garage at the rear does not contribute. The property is regarded as one of the best preserved examples of its type and reflects the suburban growth that followed railway expansion in the area.","period_of_significance":null,"architect_builder":"Architect unknown; built for Henry J.
