Hiring a general contractor is one of the biggest decisions in any Boston-area remodel. The right contractor keeps your project on budget, on schedule and up to code; the wrong one can cost you months and thousands of dollars. Massachusetts has strong homeowner protections, and knowing them makes hiring much safer.
Step 1: Check credentials
Table of Contents
- Home Improvement Contractor (HIC) registration is required for most residential contractors working on existing owner-occupied homes with one to four units. Registration can also give homeowners access to the state’s guaranty fund in some cases of loss.
- Construction Supervisor License (CSL) is required for whoever supervises structural work.
- Trade licenses: electricians, plumbers and gas fitters must hold their own state licenses.
You can look up registrations and licenses on Mass.gov. Confirm the contractor’s insurance too.
Step 2: Compare at least three written estimates
Ask each contractor to price the same scope, and compare what’s included: permits, demolition, disposal, materials, allowances for finishes, cleanup and timeline. The lowest bid often leaves things out.
Step 3: Get a written contract
Massachusetts requires written contracts for most home improvement work. Make sure yours includes the scope, total price, payment schedule, start and completion dates, the contractor’s registration number, and how changes will be handled.
Step 4: Keep deposits within the rules
Massachusetts generally limits deposits on home improvement contracts to one-third of the contract price, or the cost of special-order materials if higher. Tie later payments to completed milestones.
Step 5: Confirm permits and inspections
Most significant remodels need permits from Boston’s Inspectional Services Department or your town’s building department. Permitted work protects your safety, insurance and resale value. Your contractor should pull the permits.
Step 6: Ask about old-house experience and lead-safe work
Boston-area homes often hide older wiring, plumbing and framing. Ask how the contractor handles surprises, how allowances work, and whether they’re certified for lead-safe work in homes built before 1978.
Red flags
- No registration or license numbers.
- Large cash deposits or pressure to sign immediately.
- Asking you to pull permits in your own name.
- No written contract, or vague scope and timelines.
- No references or recent reviews.
Questions to ask every contractor
- What are your HIC and CSL numbers?
- Who will supervise the job day to day?
- Which subcontractors will you use, and are they licensed?
- How do you handle change orders and unexpected issues?
- What warranty do you provide?
