Home Inspection Guide for Massachusetts Buyers

The inspection is not a pass/fail exam. It is a survey of an imperfect object, and every house — new construction included — produces a report full of findings. The skill is not in getting a clean report. It is in knowing which three items on a forty-page list matter.

When does the inspection happen in Massachusetts?

Between the accepted Offer to Purchase and the Purchase and Sale Agreement, in a window typically five to ten days long. That timing is deliberate: it is your last clean opportunity to renegotiate or withdraw before the long contract is signed. Book the inspector the day your offer is accepted, because good ones are busy and the clock is running.

What a general inspection covers

A licensed Massachusetts home inspector examines what is visible and accessible:

Roof, flashing, gutters and drainage.
Foundation, framing where visible, and signs of movement or water.
Electrical service, panel, and a sample of outlets and fixtures.
Heating and cooling equipment, its age and its condition.
Plumbing supply and waste, water pressure, and the water heater.
Attic insulation and ventilation.
Windows, doors, grading, walkways and exterior surfaces.
Appliances that stay with the house.

Go with them. The report is a document; the walkthrough is where you learn which findings the inspector is genuinely concerned about and which are boilerplate. Ask directly: "if this were your house, what would you deal with first?"

What a general inspection does not cover

This is the part that costs people money. A standard inspection is visual and non-invasive. It excludes:

Anything behind a wall. No opening up, no moving stored belongings.
Sewer laterals. A camera scope of the line to the street is a separate specialist and, on an older house with mature trees, is one of the best few hundred dollars you can spend.
Chimneys beyond a visual look. A Level 2 chimney inspection with a camera is separate.
Septic systems. Governed by Title 5 and inspected by a separate approved inspector.
Private wells. Water quality and flow testing are separate and are not automatic.
Buried oil tanks. Common in older Massachusetts homes and a serious environmental liability. Ask.
Pools, docks, and outbuildings, usually.

The findings that matter in this housing stock

Massachusetts has some of the oldest housing in the country, which means the recurring issues are specific and predictable:

Knob-and-tube wiring. Still present in plenty of pre-war homes. Insurers increasingly decline to write a policy over it, which makes it a financing problem as well as a safety one. Call your insurance agent before the contingency expires, not after.
Lead paint. Presumed in housing built before 1978, which is most of it. Massachusetts law requires deleading of accessible surfaces where a child under six will live. Sellers must provide the state's lead disclosure package. The obligation is real and the remediation is not trivial.
Asbestos. In pipe insulation, duct wrap, floor tile and siding. Intact and undisturbed it is usually managed rather than removed; disturbed is a different conversation.
Water in the basement. Look for efflorescence on the walls, a tide line on stored boxes, a sump pump with a well-worn float. Grading and gutters solve most of it cheaply; a structural water problem does not.
Ice dam damage. Stained ceilings along exterior walls on the top floor. It points to insulation and ventilation, not to the roof.
The heating system's age. A 25-year-old boiler is not broken, but it is a foreseeable capital expense and it is fair to price it as one.
Radon. Eastern Massachusetts has elevated radon in places. Testing is inexpensive and mitigation is a known, bounded cost.

How to use the report in a negotiation

Sellers are not obliged to deliver you a perfect house, and asking for a list of forty items is the fastest way to lose their goodwill and, in a competitive market, the deal.

The framing that works: separate the findings into three piles.

1.Safety and systems — the failed heating system, the compromised structure, the electrical hazard, the active leak. These are legitimate to raise.
2.Deferred maintenance you knew about — the tired kitchen, the old windows, the roof at the end of its life if it was disclosed and priced in. These you already bought.
3.Everything else — the loose railing, the missing GFCI, the caulk. Fix them yourself after closing and do not spend leverage on them.

Ask for a credit rather than a repair wherever you can. A seller repairing on their way out the door has every incentive to do it cheaply; a credit lets you choose the contractor and control the quality.

You cannot be asked to waive it any more

This is the largest change to Massachusetts practice in years. Since October 15, 2025, 760 CMR 74.00 — adopted under the Affordable Homes Act, Chapter 150 of the Acts of 2024 — provides that a seller of residential property, or their agent, shall not condition the acceptance of an offer on the prospective purchaser agreeing to waive, limit or restrict a home inspection, and shall not accept an offer that would require them to.

That takes waiver off the table as a competitive tactic. You cannot offer it and no listing agent may ask for it. The regulation also reaches terms that leave the right on paper while removing it in practice: a window too short to schedule and read an inspection in, restricted access, or a clause preventing you from walking away over what is found.

Three things it does not do:

It does not force you to inspect. Once you are under agreement, and once the parties have signed the Massachusetts Mandatory Residential Home Inspection Disclosure, you may still decide not to. The decision has to be genuinely yours rather than something the seller or their agent asked for.
It does not end negotiation over inspection terms. The parties may still agree to a reasonable repair-cost threshold below which you will not walk, and may reasonably limit the deposit refund if you do.
It does not cover every sale. Auctions and foreclosures, transfers between relatives or former spouses, certain estate-planning transfers, and certain new construction sold with a one-year written warranty sit outside it.

Failing to deliver the required disclosure is treated as an unfair or deceptive act under M.G.L. c. 93A, which is what gives the rule its teeth.

What still helps you compete, legitimately: inspect for information only, where you keep the right to walk but agree not to come back for repairs or credits, or a pre-offer inspection done before offers are due. Both give a seller the certainty they actually want — no renegotiation, no delay — without asking you to buy a 1920s house with an unknown basement blind. the 2025 inspection law goes through the regulation in full.

What to do with the report afterwards

Keep it. It is the best maintenance plan you will ever be handed — a list, written by a professional, of what needs attention and roughly when. Work through it over the first two years and you will be ahead of the house rather than behind it.
