Wellesley's Inspections Department requires a building permit for kitchen and bath remodels involving structure, walls, or fixture relocations, with separate plumbing, electrical, and gas permits from licensed trades. Electrical permits route through Wellesley MLP for service-side coordination. Reviews tend to be more rigorous than average because of the high-value housing stock and the frequency of structural alterations in remodels here. Pre-1978 RRP rules apply to most of Wellesley's older stock — roughly 70%+ of homes predate 1978 — and add $1,500–$5,000 in lead-safe overhead. Conservation Commission review applies for work near Rosemary Brook and other wetland areas.

Wellesley pricing runs roughly 20–30% above the state median, the highest tier short of Brookline and parts of Cambridge. Mid-range bath remodels run $30,000–$55,000, with primary baths $50,000–$90,000 and high-end primary suites $80,000–$150,000. Mid-range kitchens land at $60,000–$110,000, and high-end custom work routinely runs $130,000–$300,000. Open-concept first-floor remodels with structural work and custom millwork commonly hit $200,000–$400,000, and a primary-suite addition tied to a bath rebuild adds another $100,000–$250,000 in most cases. Cosmetic-only refreshes are rare in this market — most projects involve cabinetry replacement, fixture relocation, and material specs above the state median.

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.
