Andover, MAInc. 1646
Andover is one of the Massachusetts towns where the contrast between old and new is most visible. The town center retains its colonial New England character with pre-Revolutionary homes along Main Street, while Phillips Academy — one of the oldest boarding schools in the country, founded in 1778 — occupies a significant portion of the town's land area. The surrounding neighborhoods range from dense, modest housing near the Shawsheen River to large-lot estates in the western hills.
Route 93 and Interstate 495 cross in Andover, making it a major commuter node and bringing commercial and office development alongside the residential base. The town's housing stock reflects waves of development: colonial-era homes near the center, early suburban expansion in the 1950s-60s, and newer construction in subdivisions carved from former farmland. Fire protection, assessed values, and building condition vary significantly across these different eras and neighborhoods.
