O'Connor Development is a one-crew outfit in East Falmouth built around the bigger jobs — additions, basement finishes, and start-to-finish bathroom remodels — run by Michael O'Connor, a licensed Construction Supervisor and Home Improvement Contractor who the company says has worked construction for over a decade and also serves as a firefighter. Nine Google reviews since early 2026 average a perfect 5.0, and the same detail keeps showing up: Mike, personally, running the job on site. One family had him build a large office addition and called the process stress-free, finished ahead of schedule. Another used him for a full bathroom remodel and said the timeline was respected start to finish. A third hired him to finish a basement and replace a gas stove — and got a bonus: he built the kids a sandbox that wasn't part of the scope and let them help out. A separate family had him turn a patio into a three-season room and called him one of the hardest-working people they'd worked with. His Massachusetts Home Improvement Contractor registration (#209029) is active and registry-verified, matching the number the company lists on its own site. The company also names several of Michael's personal credentials — a hoisting engineer license, a commercial driver's license, a real estate license — though those are self-reported and haven't been checked against any registry. There isn't much to flag: every review on file is five stars, and nothing in the record points to a complaint, a scheduling miss, or a pricing surprise. The one thing worth noting is scale — the written history is nine reviews deep, all from 2026, so it's a newer public track record even though the license and crew behind it are established. O'Connor Development reads like the right call for a homeowner planning a real project — an addition, a basement, a full bathroom gut — who wants one person running it start to finish rather than a rotating crew. Worth confirming the project timeline and how hands-on Michael will be day to day, since that's what reviewers keep pointing to.
Michael and the team at O'Connor Development did outstanding work. I recommend them without hesitation. We hired them to build a large office addition onto our home, and the experience was excellent from start to finish. Michael has a sharp eye for detail. He takes a lot of pride in his high-end craftsmanship, and the final result shows it. Michael and his crew showed up ready to work every day and stayed focused. He kept us informed at every stage, answered our questions, and gave us clear timelines. The whole process was stress-free. He also finished ahead of schedule. We are thrilled with the result. If you want a builder who does excellent work, communicates honestly, and treats your home and family with care, hire Michael.
We bought a new home from O'Connor Development a little over a year ago, and are so glad that we did. The quality of the build, fit & finish, design choices that were made are all outstanding. Mike and his crews truly care about the the homes they build. And you're not dealing with some developer in another city or state, Mike is local. He takes pride in his homes as well as how they are improving the neighborhood. Highly recommend O'Connor Development!
