Medford has 61,748 residents and about 26,761 housing units in Middlesex County, with a median construction age of 83 years. The housing is a mix of attached two-families and triple-deckers in the Wellington and Medford Square neighborhoods, alongside more detached housing in the Tufts University area and along the Medford/Winchester border.

The Mystic River runs along Medford's southern edge and creates real wetland-buffer permitting requirements for a meaningful share of properties. Farther from the river, the city's 83-year housing stock produces frequent structural repair work on existing porches, where failed ledger connections and non-code railings are common findings once an old structure is opened up.
