Lynnfield is an Essex County suburb of 12,925 residents with 4,846 housing units and a median home age of 60 years. The town developed primarily in the 1950s through 1970s, producing a housing mix of ranches, raised ranches, and split-levels on mid-size lots, with some newer construction in developments near Route 128. Lynnfield borders Wakefield, Reading, and Peabody in a quiet inner-ring suburb position.

At 60 years old on median, a large share of Lynnfield's decks were built before the stricter 780 CMR ledger attachment and guardrail standards that took effect in the 2000s. When owners pull permits for re-decking or repairs, inspectors consistently flag the ledger connection and railing height on these older structures.
