The purchase inspection and the document checklist

A general home inspection in Massachusetts has edges written into regulation, and most of what matters in this housing stock sits outside them: the septic system, the private well, a buried oil tank, the inside of a chimney flue, radon. Knowing where the boundary runs is what lets you hire the right specialists and use a short window well.

What a general inspection actually is

Home inspectors here are licensed by the Board of Registration of Home Inspectors, and the job is defined by the standards of practice at 266 CMR 6.00. The inspector observes the listed systems, from structure and roof through plumbing, electrical and heating, and reports their physical condition, including observable safety hazards, as observed at the time of the inspection.

Three phrases do the work. Readily accessible: reachable without moving stored items or cutting into finishes. Observable: visible rather than inferred. At the time of the inspection: a basement dry in August tells you about August. The regulation states plainly that an inspection is visual and not technically exhaustive.

What it explicitly leaves out

The exclusions at 266 CMR 6.05 are the point, not the fine print. An inspector need not report the remaining life of anything, why a repair is needed, what would fix it, or whether the house complies with any code unless you contract for that separately. Anything cosmetic, inaccessible, underground or not permanently installed is out of scope, and so is moving stored belongings, operating a system that is shut down, predicting a failure or an operating cost, and measuring how far damage extends. No warranty comes with the report.

These are not inspected at all unless bought separately: radon, wood-destroying insects, energy efficiency, soil conditions, and environmental testing of any kind, including mold, asbestos, lead paint and PCBs. So on a typical property here, where the septic and well are underground, the oil tank may be, the flue is inside the chimney and radon is invisible, a full-standard inspection answers none of it.

The specialists, and the trigger that adds each one

Do not order every test on every house. Add a specialist when three things are true: the item is outside the general scope, being wrong is expensive, and the answer changes what you will pay.

Add this	Trigger	What it answers
Title 5 septic inspection	Not on town sewer	Pass, fail or conditional, and the bedroom count the system was approved for, which caps what counts as a bedroom
Well quality and yield test	No municipal water	What is in the water, how much the well produces, and what any treatment equipment treats
Radon in air, and in water on a well	Every house, every time	Whether mitigation is needed. Untested is not the same as clear
Chimney and flue camera scan	Any appliance venting into masonry	The liner's condition, which nobody sees from the roof or the firebox
Wood-destroying insect inspection	Wood meeting soil, older sills	Active infestation, past damage, conducive conditions
Structural engineer	A bowed foundation wall, a sagging ridge, a cut joist	Whether it is moving and what a repair involves; inspectors may not collect engineering data
Oil tank evaluation	Oil heat now, or evidence of it before: an orphan fill pipe	Whether a tank is buried, and whether a removed one was closed out. Chapter 21E liability runs with the land

On a pre-1978 house, lead paint is its own inspection with its own statutory window. Order a Title 5 inspection early rather than last: what a Title 5 inspection covers and what a failure actually means explains why the result can move a closing date.

What the Massachusetts waiver rules say now

Massachusetts regulated inspection waivers through 760 CMR 74.00, adopted by the Executive Office of Housing and Livable Communities under the 2024 Affordable Homes Act and effective 6 June 2025. The regulation exempts a sale where the offer to purchase or the purchase and sale agreement, whichever came first, was executed on or before 15 October 2025, so it bites on anything executed after that date. Those are two different dates doing two different jobs, and they are often conflated. Read the current text yourself.

• A seller or the seller's agent may not condition acceptance of an offer on your waiving, limiting or forgoing a home inspection, nor accept an offer that requires it. Auction sales are carved out.
• Terms that render a home inspection meaningless break the same rule: unreasonably limiting your ability to schedule, receive and review one, or barring you from walking away on an unsatisfactory result.
• Reasonable limits remain negotiable. The parties may still agree on a repair-cost threshold, or on when a deposit comes back.
• Before the first written contract, the seller's agent, or an unrepresented seller, must give you the state's mandatory disclosure form stating that the purchase is not contingent on waiver and that you may have the premises inspected by a licensed inspector.
• After that disclosure and an accepted offer, you may still choose to waive, provided the decision is not influenced or required by the seller.

The exemptions are narrow: an offer to purchase or purchase and sale agreement executed on or before 15 October 2025, a sale to a relative, a transfer to a former spouse under a Chapter 208 judgment, foreclosure, a deed in lieu, a reconveyance releasing a debt or lien, estate-planning transfers to a relative including through trusts, and new construction where the first contract predates substantial completion and the seller gives an express written warranty of at least one year covering construction and the functioning of the systems. That last exemption is why, if the house is not built yet, you should read what a new-construction buyer checks that a resale buyer never has to before signing anything.

Reading the report without treating every line as a defect

The report is written to a standard that requires disclosure of conditions, not to a standard of what matters. Forty pages on a 1955 cape is normal, not a verdict.

Sort every finding into four piles. Hazards and active water, such as an ungrounded bathroom circuit or a failing flue. End-of-life systems with a known age and replacement cost. Deferred maintenance you would do anyway. And description, the lines that simply record how the house was built.

"Recommend further evaluation by a qualified contractor" is the regulatory exit: the item falls outside what an inspector may determine. It means get a quote, not that something failed. A number changes a negotiation and an adjective does not, so negotiate two or three items with figures attached, rather than the list.

The documents to collect alongside

• Permits and sign-offs. Ask the building department by address for the permit history and whether anything is open or expired. A finished basement or deck that never got its final inspection becomes your problem at your closing. Compare it against the assessor's record.
• The Title 5 report and the system's paperwork. For a newer system, ask the board of health for the as-built plan and the Certificate of Compliance, which confirms it was built to the approved design.
• Well records. The completion report or driller's log, depth, yield, pump age and prior test results.
• The plot plan or recorded subdivision plan. Where boundaries, easements and rights of way actually run. Upton, Westborough, Northbridge, Grafton, Mendon and Millville record at the Worcester District Registry of Deeds; Hopkinton, in Middlesex County, records at Middlesex South.
• Utility records. Twelve months of electricity, plus the oil, propane or gas history. That is the operating cost of the house, and no inspection report carries it.
• The conservation commission file. Whether a wetlands resource area touches the parcel, and whether an order of conditions was closed out.
• Insurability. Ask for the prior claims history and get a quote before the contingency expires. Roof age, knob-and-tube wiring and a buried tank are underwriting questions too.

Putting the window to work

Order the general inspection the day the offer is accepted, book specialists the same afternoon, and send document requests in parallel. Everything here has a lead time.

The wider sequence is laid out on the buyer's guide to this market and its public records. The lender runs its own review of the same house and can reach a different conclusion than your inspector did; how underwriting and the appraisal judge the property itself covers what that does to your dates.
