Remodeling in Lexington
Historic Colonials and mid-century modern landmarks.
Lexington’s housing tells the town’s history. Colonial-era and nineteenth century homes cluster near Lexington Center and along historic roads, while post-war Colonials, capes and split-levels fill many neighborhoods.
Lexington is also home to some of the best-known mid-century modern neighborhoods in New England, including Five Fields and Peacock Farm, which are listed on the National Register of Historic Places.
Each kind of house calls for a different approach. A mid-century home with post and beam framing and walls of glass needs a very different kitchen plan than a center-chimney Colonial.

Local planning
What to know before remodeling in Lexington.
Lexington has active historic preservation and its own permitting process.
Permits
Building, electrical and plumbing permits are issued by the Town of Lexington. Additions and structural work need plans.
Historic districts
Exterior changes to properties in Lexington’s local historic districts are reviewed by the Historic Districts Commission before work begins.
Demolition delay
Lexington’s demolition delay bylaw can apply to projects that demolish all or part of a significant older building.
Mid-century homes
Post and beam framing, flat or low-slope roofs, radiant heat and large glass walls require careful planning when kitchens, baths or additions change.
ADUs in Lexington
Under the 2025 state law, one ADU of up to 900 square feet, or half the size of the main home if smaller, is allowed by right in single-family zoning districts. Lexington can still apply local rules such as setbacks and site plan review, so we check them for your lot.
