M. O'Connor Contracting, Inc.

M. O'Connor Contracting is a West Roxbury general contractor and construction manager that has been building in Massachusetts since 1976 — the kind of firm that renovates a town library or a school science wing rather than one that advertises for kitchen jobs. Its Massachusetts home improvement registration, HIC 177282, is registry-verified active, and the Better Business Bureau grades it A+ — though it is not BBB accredited. The BBB record puts the business start at 1 January 1976, incorporation that April, 15 employees, and Michael O'Connor as president; the company's own site says he founded it in 1976, beginning in residential construction before expanding into commercial work. It is still winning public work on the Outer Cape. The Provincetown Independent reported in April 2026 that of five companies bidding on Truro's new $26.2-million public works facility, the lowest bid came from M. O'Connor Contracting — the same firm, the paper noted, that built Provincetown's police station in 2024. Truro's consultant told the select board the low bid was legitimate and not too good to be true. The rest of the public record of its work is a permit trail rather than a review history. BuildZoom's permit-derived profile shows nine projects including a $9.9 million Newton early-childhood program building, a theater addition at a South Easton vocational school, science-lab and library renovations in Newton, re-siding and window repairs in Arlington, work at Chestnut Hill and Cambridge, and a 2023 shed and pergola permit at 14 Pine Rd in Dennis on Cape Cod. It also appears on the Town of Reading's contractor prequalification listing and in the Dover Community Center bid tabulation; its own portfolio names the Sharon Library, Emery Grover and Norton Town Hall. For a homeowner the honest picture is mixed. The BBB describes it as doing remodeling, additions and new construction for residential as well as commercial customers, and Houzz files it under home additions, home remodeling, basement remodeling and accessory dwelling units — so residential work is genuinely on the menu. But the firm's own site leads with historical renovation and municipal buildings, and there is not a single customer review on any platform: BBB, Houzz and BuildZoom all publish none. So ask directly whether your project size is one they take, and for references from recent residential clients rather than municipal ones. Note too that BuildZoom's 'BZ SCORE: 93' is a permit-derived number, not customer sentiment — it says nothing about how the work was received.
