Summary
Operating as a framing contractor in Boston requires both state and local compliance. At the state level, you need a Massachusetts Construction Supervisor License (CSL) - Unrestricted, which requires experience, passing an exam, and ongoing education. For residential work in Boston, you must also register as a Home Improvement Contractor with the city, including a $5,000 bond. All framing projects require building permits through Boston's Inspectional Services Department, with mandatory inspections at key milestones. Insurance requirements include general liability and workers' compensation, with many clients requiring higher coverage limits than state minimums. Boston's strong construction market supports higher rates than many areas, but contractors must factor in elevated material costs and strict code enforcement when bidding projects.
