Septic companies in Massachusetts

Massachusetts is a Title 5 state, which means a septic inspection is required before a home is sold or enlarged, and it has to be done by a DEP approved System Inspector. Your local board of health is the approving authority for most systems and can set rules beyond the state minimum. This guide covers the inspection and how old it may be, the family transfer exemption, the two year clock a failed system starts, and the tax credit and betterment loans that help pay for the fix.

Who Regulates Septic Systems in Massachusetts

Sources: Massachusetts General Court; Massachusetts Department of Environmental Protection. Checked 2026-09-18.

Massachusetts writes the septic rules at the state level and hands the decisions to your town. The rule is Title 5, part of the state environmental code. The office that grants or refuses your permit is the local board of health.

The commissioner of the Department of Environmental Protection adopts and amends the regulations known as the state environmental code opens in a new tab, and that code deals with matters affecting the environment and the wellbeing of the public, including standards for the disposal of sewage opens in a new tab. Title 5 is the part of that code covering your system.

Boards of health are the approving authorities for most systems, and DEP is the approving authority for state and federal facilities opens in a new tab. Any health officer or board of health whose authority includes issuing permits for the construction, maintenance or alteration of individual sewage disposal systems opens in a new tab is the office you are dealing with.

A town can go beyond Title 5, and it has to say so out loud when it does. Boards of health may make reasonable health regulations, with a summary published in a newspaper opens in a new tab, and before adopting a regulation that exceeds the minimum requirements for subsurface disposal of sanitary sewage in the state environmental code, a board shall state that at the hearing opens in a new tab.

There is a reason no county office appears in this guide's table. Massachusetts abolished the government of a list of counties outright, each on its own transfer date opens in a new tab, Middlesex first in 1997 and Berkshire last in 2000. Where a county government does survive it runs deeds, engineering and facilities rather than health, so the board of health in your town or city is the office you want.

Licenses and What to Check Before You Hire

The credential Massachusetts is strictest about is the one that matters when you sell. It is called a System Inspector, it is approved by DEP, and it is a separate approval from installing.

Inspectors who take the course and pass the exam receive a certificate from DEP identifying them as approved system inspectors opens in a new tab, and DEP publishes a list of these system inspectors at least annually opens in a new tab. Your local board of health holds the list of DEP approved soil evaluators and system inspectors, and only those approved under the regulations can perform the required inspections and soil tests opens in a new tab.

Some professionals qualify through the credential they already hold. Massachusetts Registered Professional Engineers with a concentration in civil, sanitary or environmental engineering, Massachusetts Registered Sanitarians and Certified Health Officers may perform inspections opens in a new tab.

Others qualify by trade, which is why your installer may also be an inspector. Board of health members and agents, professional home inspectors, licensed septage haulers, system installers and Engineers in Training are also eligible opens in a new tab. Being eligible is not the same as being approved, so ask which list they are on.

Two more points are worth knowing before you hire. Septage collected for hire goes to facilities provided by cities, towns and sewerage districts subject to DEP approval opens in a new tab, and the law addresses the case of a septic system installer who sits on the board of health, and when they may work within that board's jurisdiction opens in a new tab.

We hold no Massachusetts register of our own, so no listing here carries a verified credential for this state. DEP's published inspector list and your board of health's copy of it are the two places a claim gets checked.

Permits, Inspections and Selling a Home

Sources: Office of the Attorney General, Commonwealth of Massachusetts; Massachusetts Department of Environmental Protection; Massachusetts General Court. Checked 2026-09-18.

In Massachusetts, selling a house does require a septic inspection, so plan for it early. Title 5 requires inspections of septic systems and cesspools before a home is sold or enlarged opens in a new tab. The inspection must be conducted by an approved System Inspector, who records the results on a DEP approved form and submits it within 30 days opens in a new tab.

The age of the inspection is what catches sellers out. For most properties the inspection must have occurred within two years prior to the transfer, or three years when the system has been pumped on an annual basis opens in a new tab. If the system has been pumped annually, the inspection is valid for three years opens in a new tab, so annual pumping receipts are worth keeping.

Two situations get their own timing. If weather conditions prevent inspection at the time of transfer, it must occur as soon as weather permits and no later than six months after the transfer opens in a new tab, and in a foreclosure, inspections must occur within two years before or six months after the execution of the memorandum of sale opens in a new tab.

There is an exemption, and it is about who you are selling to. The department shall not require an inspection if the transfer is of residential real property between certain relationships opens in a new tab, namely current spouses, parents and their children, full siblings, and a transfer into a revocable or irrevocable trust opens in a new tab. A system that fails must be repaired or upgraded within two years following inspection, regardless of whether the property is sold opens in a new tab.

Keeping a System Working

In Massachusetts pumping is not only maintenance, it is paperwork that buys you time: a system pumped on an annual basis carries an inspection valid for three years rather than two opens in a new tab, against the EPA's guidance of an inspection at least every three years opens in a new tab. Innovative and alternative systems are much more complex than standard ones and require their mechanical components to be maintained on a regular schedule opens in a new tab.

Help Paying for Repairs

Massachusetts has a tax credit for this work, and the numbers are in the statute. A credit equal to 60 per cent of the design and construction expenses is allowed for repairing, replacing or upgrading a cesspool or septic system, or connecting to a sewer opens in a new tab, and the credit shall not exceed $4,000 in any tax year, with excess applied over the following five tax years up to an aggregate maximum of $18,000 opens in a new tab.

There is also a loan route that runs through your town rather than the state. Using State Revolving Fund loans from the Trust, communities can provide betterment loans to assist homeowners who must address septic system failures opens in a new tab, and that betterment loan programme is administered by the board or department of health and provides direct financial assistance to homeowners opens in a new tab.

You can ask for it yourself. Where the state environmental code requires the repair, replacement or upgrade of a septic system, the owner of a structure used for human habitation may petition the board of health opens in a new tab. On Cape Cod, Barnstable County offers low interest betterment loans to homeowners facing the costs of repairing or replacing failed systems or upgrading to innovative and alternative technology opens in a new tab.

Find Your Town Board of Health

Massachusetts septic permits and Title 5 inspections go through the board of health of your town or city, not through a county. Six of the counties below no longer have a county government at all, and of the rest only Barnstable County runs a health department, which does not issue permits either. Each county is listed with what we could confirm. Checked 2026-09-18.

Questions People Ask

Do I need a septic inspection to sell my house in Massachusetts?

Yes. Title 5 requires inspections of septic systems and cesspools before a home is sold or enlarged, and the inspection must be done by a DEP approved System Inspector who files the results on a DEP form within 30 days.

How old can the inspection be?

For most properties it must have occurred within two years before the transfer. That stretches to three years if the system has been pumped annually, so keep the pumping receipts. Weather delays allow it up to six months after the transfer.

I am transferring the house to family. Is an inspection still needed?

There is an exemption for residential transfers between current spouses, parents and their children, full siblings, and transfers into a revocable or irrevocable trust. Outside those relationships, the requirement applies.

My system failed the inspection. What now?

It must be repaired or upgraded within two years following the inspection, whether or not the property is sold. The tax credit and your town's betterment loan programme are the two routes to help with the cost.

How much is the Title 5 tax credit worth?

Sixty per cent of design and construction expenses, capped at $4,000 in any tax year, with the excess carried over the following five tax years up to an aggregate maximum of $18,000.
