Kitchen remodel mistakes I see in Greater Boston homes, and how to avoid them

I've walked into a lot of Greater Boston kitchens that were remodeled once already, and the same kitchen remodel mistakes keep showing up. Most of them aren't about taste. They're about planning, code and the quirks of 100-year-old houses in Somerville, Cambridge and Medford. Here's what not to do, and how to tell if a kitchen remodel is worth it for you.

Mistake 1: Designing the look before the layout

People fall in love with a cabinet color before deciding where the sink, range and fridge go. In narrow triple-decker kitchens, with radiators, chimneys and back-stair doors in the way, layout is everything.

• Map how you actually cook and where people walk through.
• Check clearances around doors, the dishwasher and the oven door.
• Remember that moving plumbing or gas costs real money. Moving it for no clear reason is the most expensive regret I see.

Mistake 2: A range hood that doesn't really vent

A recirculating microwave over a gas range doesn't clear much smoke or moisture. The Massachusetts Residential Code is based on the 2021 International Residential Code with state amendments, and the IRC sets clear rules:

• A ducted kitchen exhaust must discharge outdoors, never into an attic or another space inside the building (IRC M1503.3).
• A hood that can exhaust more than 400 cfm needs makeup air when certain fuel-burning appliances sit inside the home's air barrier (IRC M1503.6).

Buying a huge hood without planning the duct route or makeup air is a classic mistake. Size it for your range and your house.

Mistake 3: Assuming old wiring can handle a new kitchen

Many 1900–1930 houses still have original circuits, shared kitchen outlets or a small electrical service. New appliances, an induction range, under-cabinet lights and a microwave add up fast.

• Have a licensed electrician check the panel and service before design is final.
• Work must meet the Massachusetts Electrical Code, which has been based on the 2026 NFPA 70 since April 24, 2026.
• If you plan to go induction, Mass Save offers $500 when an ENERGY STAR induction stove replaces a gas or propane stove, for 2026 purchases. Get the old stove verified before it comes out.

Mistake 4: Ordering cabinets before measuring the opened-up room

Old Somerville walls are rarely plumb and floors are rarely level. Measurements taken over plaster can change once walls are opened or furred out.

Mistake 5: Skipping permits and lead-safe work

Skipping a permit can come back to bite you during a buyer's inspection at resale, and it leaves nobody checking the electrical and plumbing.

• Somerville requires a building permit before work starts; electrical permits must be pulled by a licensed electrician, and plumbing and gas permits by a licensed plumber.
• In a home built before 1978, Massachusetts requires a licensed lead-safe renovation contractor for renovation, repair or painting.
• Demo in an old kitchen can spread lead dust into the rest of the unit and to neighbors in a two-family or triple-decker. Containment and HEPA cleanup aren't optional.

See my Somerville permit guide and lead paint guide for the details.

Mistake 6: An unrealistic schedule and a vague contract

A kitchen is a chain of trades, inspections and deliveries. One late countertop or failed inspection pushes everything after it.

1. Order long-lead items before demo starts.
2. Plan for permit review and inspections in the schedule.
3. Set up a temporary kitchen; you'll be without one for a while.
4. Get it in writing. Under M.G.L. c. 142A, s. 2, home improvement contracts over $1,000 must be written, and the deposit generally can't exceed one-third of the price or the cost of special-order materials, whichever is greater.

My contractor hiring checklist covers what to ask before you sign.

Is a kitchen remodel worth it?

Financially, smaller usually wins. In the 2025 Cost vs. Value report for Boston, a midrange minor kitchen remodel recouped about 119% of its cost at resale, while a midrange major remodel recouped about 41%. A big remodel is worth it when you're staying and the kitchen truly doesn't work for your life. A refresh is often the smarter move if you're selling soon.
