Dover's Building Department requires a building permit for any kitchen or bath remodel that touches structure, walls, or fixture relocations, with separate plumbing, electrical, and gas permits from licensed trades. Additions add zoning review under Dover's large-lot zoning, and work near the Charles River, Trout Brook, or the town's extensive wetlands often triggers Conservation Commission sign-off. Because Dover has no public sewer and essentially every property is on private septic, adding a bathroom or bedroom routinely triggers a Title 5 review — a defining wrinkle here. Homes built before 1978 fall under federal RRP lead-safe rules, adding roughly $1,500–$5,000 to qualifying projects.

Dover pricing runs well above the Massachusetts median — among the highest in the state — reflecting the estate market and the scale of typical projects. Mid-range bath remodels run $24,000–$42,000, with primary baths $40,000–$72,000 and high-end suites $65,000–$130,000. Mid-range kitchens land at $48,000–$85,000, and high-end custom work — the norm here — runs $90,000–$200,000. Full reconfigurations and additions push totals to $120,000–$280,000. Septic capacity is the most common cost driver, since every property is on a private system and high-end additions often outstrip the existing system.

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.
