Do I need a Title 5 inspection?
Five questions, one plain answer, read straight from 310 CMR 15.301.
Title 5 calls for an inspection at particular moments, nearly all of them tied to a change of hands or a change of use. It does not call for one because a system is old or a buyer is uneasy, though a buyer can still ask. Answer the questions and the result updates as you go.
Your answer
Answer the questions to see whether the rule applies.
Read the rule, the exempt transfers and the two-year clock in the Title 5 guide, or see how the visit itself works on the Title 5 inspections page.
This is a plain-language reading of 310 CMR 15.301, not legal advice. Your board of health has the final say on your property.
What the rule actually turns on
Under 310 CMR 15.301(1) a septic system must be inspected at or within two years before a transfer of title, and the buyer has to receive the full report. That single sentence accounts for most inspections on Cape Cod and the South Shore. A passing report stays usable for two years from the inspection date, or three years if you can produce records showing the tank was pumped at least once a year in between, and one report covers more than one transfer inside its window.
Several things that feel like transfers are not. Granting a mortgage, refinancing, changing the form of ownership among the same owners, adding or removing a spouse from the deed, and replacing a trustee, guardian or conservator are all outside 15.301(2). Separately, 15.301(4)(d) exempts residential transfers between current spouses, between parents and children, between full siblings, and into a trust where at least one beneficiary is a first-degree relative of the grantor. Those exemptions turn on how the deed is written, so confirm the wording with your closing attorney rather than with this page.
The second trigger has nothing to do with selling. Under 15.301(5) an inspection is required before any change in the type of establishment or any increase in design flow, which is what adding a bedroom does, and a cesspool or failing system has to be upgraded before that change goes ahead. Design flow is counted at 110 gallons a day per bedroom, so the bedroom count on the plan is what matters, not the square footage.
A designated Nitrogen Sensitive Area does not change whether you need an inspection. What it changes is the upgrade: the best available nitrogen reducing technology rules in 15.215 apply there, which is why a replacement in one of those watersheds usually has to be an I/A system. The nitrogen rules guide covers which watersheds were designated and what the towns have done since. Whatever the result here, only a MassDEP-approved System Inspector may sign the official form, and it has to reach the board of health within 30 days. Program terms are set by the agencies and change; confirm with the state or county page linked here.
Questions homeowners ask
How long does a passing Title 5 report last?
Two years from the inspection date for a transfer of title, and up to three years when pumping records show the tank was pumped at least once a year in between. One report covers more than one transfer inside that window, so a house that changes hands twice in 18 months needs a single inspection.
Which transactions are not a transfer of title?
Granting a mortgage or other security interest, refinancing, changing the form of ownership among the same owners, adding or removing a spouse from the deed, and replacing a trustee, guardian or conservator are all outside 310 CMR 15.301(2), so none of them triggers an inspection on its own.
What happens if winter weather stops the inspection before closing?
310 CMR 15.301(1) lets the inspection happen as soon as weather permits and no later than six months after the transfer when frozen ground or snow makes it impossible beforehand. Write the arrangement into the purchase agreement so the buyer, the seller and the lender all hold the same deadline.
Does a nitrogen sensitive area change whether I need an inspection?
No. The inspection triggers in 310 CMR 15.301 are the same everywhere in Massachusetts. What a designation changes is the upgrade: the best available nitrogen reducing technology rules in 310 CMR 15.215 apply inside a designated area, so a replacement there generally has to reduce nitrogen.
The process
From your request to a site visit
-
Your request goes to one local septic company
It goes to a single septic company that works in your town and handles your kind of job. It is not sold to a list, and you will not get calls from five companies.
-
They call to set up a site visit
Expect a call, usually within one business day. The contractor asks about the house, the inspection report if you have one, and your timing, then books a visit.
-
You get a written quote and decide
After the visit you receive a written estimate with the scope and the permit plan. There is no fee and no obligation. If it is not a fit, say so and that is the end of it.
