CO Marano Builders Inc is a Canton design-build outfit run by Christopher O Marano, holding an active Massachusetts home improvement contractor registration (#152642) for the company and an active construction supervisor license (CS-077387) in Marano's own name. Permit records show 34 projects, mostly residential remodels and additions: a $210,000 addition with a golf simulator in Milton (2023), a $220,000 kitchen-and-bath renovation in Chestnut Hill (2021), a $100,000 gut renovation in South Boston (2021), and a project in Wellesley Hills. The company also takes on commercial work — a warehouse demolition and loading dock in Hyde Park, a $300,000 conversion of a doctor's office into a dental office in Braintree, and a renovation in Brockton. This is a contractor built for bigger residential projects — additions, whole-home remodels, kitchen-and-bath renovations — with commercial work on its résumé too. Confirm the project scope and timeline in writing, and ask which license covers the specific job.
