Title 5 septic inspections at property transfer, explained
Reviewed by Title 5 Roster staff
Title 5 of the Massachusetts State Environmental Code (310 CMR 15.000) governs septic systems. Most sales of a property with a septic system or cesspool need a system inspection by a MassDEP-approved System Inspector.
What does Title 5 require when a home is sold?
Most sales need a Title 5 inspection by a MassDEP-approved System Inspector within 2 years before the sale (valid 3 years with annual pumping records), reported on the MassDEP form within 30 days.
- An inspection within 2 years before the sale. It stays valid 3 years if the system was pumped every year and the report includes the records.
- If weather prevents inspection, it can happen up to 6 months after the transfer, if the seller notifies the buyer in writing.
- The inspector must use the MassDEP form and submit the report within 30 days, usually to the local Board of Health. The buyer gets a copy.
- One inspection covers multiple sales within its 2-year window.
Which property transfers are exempt from a Title 5 inspection?
Common exemptions include transfers between spouses, parents and children or full siblings (and certain trusts), refinancing, a recorded Board of Health upgrade or sewer agreement, and systems with a recent Certificate of Compliance.
- Transfers between spouses, parents and children, or full siblings, and certain trusts.
- Refinancing, taking a mortgage, or changes where no new parties are introduced.
- A signed, recorded agreement with the Board of Health to upgrade or connect to sewer within 2 years.
- A new or upgraded system with a Certificate of Compliance in the past 2 years (up to 3 with pumping).
What do pass, conditional pass and fail mean in a Title 5 inspection?
A pass means the system protects health and the environment on the inspection date; a conditional pass means specific components need repair; a fail means the system must be upgraded within 2 years.
- Pass: the system can protect public health and the environment as of the inspection date. That is not a guarantee it will keep working.
- Conditional pass: specific components need repair or replacement, such as a metal or cracked tank, a broken pipe, an uneven distribution box, or a faulty pump chamber. Once repaired with Board of Health approval, the system passes. Soil absorption systems and cesspools cannot get a conditional pass.
- Fail: the system must be upgraded within 2 years unless the Board of Health or MassDEP sets another schedule. The obligation remains even if the owner cancels the sale.
How does Title 5 apply to condos, shared and large systems?
Condominiums with 5 or more units and shared systems are inspected every 3 years; smaller condos inspect every 3 years or within 2 years before a unit's sale.
Condominiums with 5 or more units inspect all systems every 3 years. Smaller condos either inspect every 3 years or inspect the unit's system within 2 years before its sale. Shared systems are inspected every 3 years.

Frequently asked questions
How long is a Title 5 inspection good for?
Generally 2 years for a sale. It stays valid for 3 years if the system was pumped at least once a year and the report includes the pumping records.
Who pays for the Title 5 inspection?
The property owner (seller) is responsible for arranging it. Buyer and seller can shift that responsibility in writing before the transfer, as long as the inspection still happens on time.
Can a town health agent do my inspection?
Only a MassDEP-approved System Inspector can do it, and an inspector may not act as an agent of the Board of Health while also representing the owner.
What if it's winter and the ground is frozen?
If weather prevents the inspection before the sale, it can be done up to 6 months after, provided the seller tells the buyer in writing.
