The Oliver Hutchins House is an historic house at 79 Elm Street in Chelmsford, Massachusetts. The 2+1⁄2 story house was built in the 1820s, probably by Oliver Hutchins and his brother. The house's foundations and other stone elements indicate that the Hutchinses were probably associated with the local granite quarries in some way. The house is one of a few local houses that is transitional between Georgian and Federal styling: the basic plan of the house is Georgian, despite the lack of central chimney, and the exterior and interior woodwork are heavily influenced by the publications of Asher Benjamin.The house was listed on the National Register of Historic Places in 1985.

The Hildreth-Robbins House (also known as Red Wing Farm) is a historic house at 19 Maple Road in Chelmsford, Massachusetts. The main block of the 2+1⁄2-story wood-frame house was built in three stages, most likely over the course of the second half of the 18th century. That block is connected to a 19th-century barn (post-1860) via a long single-story ell. The property is significant as one of the major farmsteads of south Chelmsford of the 18th and 19th centuries. It is also distinctive as a rare 18th-century farm that was owned by a woman, Sarah Hildreth.The house was listed on the National Register of Historic Places in 2006.

The Barrett–Byam Homestead is a historic house, now headquarters of the Chelmsford Historical Society, located at 40 Byam Road, Chelmsford, Massachusetts, United States.

The homestead was established in 1663 by Thomas Barrett, who bought a house and 52 acres (21 ha) of land from a James Parker. It was originally built as south-facing "saltbox" with a central chimney and fireplace in every room. The heating system appears to have been rebuilt circa 1800 with Rumford fireplaces in each room.

The "Old Chelmsford" Garrison House (also known as the Old Chelmsford Garrison House Complex) is a historic house in Chelmsford, Massachusetts. It is the oldest house in Chelmsford, and has been preserved by the Garrison House Society as a museum. It was listed on the National Register of Historic Places in 1973. The exact date the building was erected is not known; it is claimed by the Society to have been built before 1691, when it is claimed to be one of the houses listed as a garrison house in Chelmsford, but a 1702 deed transferring land on which it stands does not mention it. Thomas Adams deeded the land to his son, Peletiah Adams, in 1683, and Peletiah deeded the land to his two sons in 1702, who probably built the house. Stylistic analysis of its construction also supports a post-1700 construction date. The same stylistic analysis casts doubt on the belief that the house actually served as a fortified garrison.Before the title passed to the Garrison House Society in 1952, only three families had previously owned it. Very few modifications had been made to it in all that time, making it a relatively accurate historic showpiece. The house now shares its lot with a barn, summer kitchen, a working blacksmith shop, an herb garden, a craft house and the "Hill Jock House," which was saved from destruction and moved in 2004 to the lot shared by the Old Chelmsford Garrison House.
