Charlie Allen Renovations

Cambridge Inspectional Services requires a building permit for any fixture relocation, plus separate plumbing, electrical, and gas permits as appropriate. The online portal moves standard residential permits through in roughly one to two weeks. Pre-1978 housing — the overwhelming majority of Cambridge — triggers EPA RRP rules on any painted surface disturbance. Cambridge also has multiple local historic districts (Old Cambridge, Half Crown-Marsh, Mid-Cambridge Conservation) that regulate exteriors only; interior remodels aren't restricted, but condo-board approval is the bigger gate in most buildings.

Cambridge runs at the top of the state's cost band, on par with Boston and Brookline. A mid-range bath remodel typically lands $24,000–$42,000, with high-end primary baths in Avon Hill or Harvard Square crossing $60,000. Kitchens usually fall in the $50,000–$90,000 range for a full mid-range remodel, with custom-cabinet jobs in single-family Victorians pushing $140,000+. The biggest cost drivers are condo-association requirements, contractor liability insurance minimums (often $2M+), parking and dumpster permits, and the prevalence of knob-and-tube wiring and cast-iron drain stacks in pre-WWII buildings.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential kitchen & bath remodel work; ask for the registration number and check it before paying a deposit.
