Title 5 Conditional Pass: What It Means in 2026 and Why Buyers Should Plan for the 24-Month Re-Inspection

TL;DR. MA Title 5 conditional pass under 310 CMR 15.301(7) explained. What carries to the buyer at sale, the 24-month re-inspection trap, and the budget you need.

The seller's agent emailed the Title 5 report Tuesday. The cover page reads "Conditional Pass." Your buyer's agent says "great, we can close." Your inspector — if you have one looking at it — says "wait, what's the condition?"

Conditional pass is the most misunderstood outcome on Title 5 inspection report. It's not a pass. It's a deferred fail with a 24-month clock that the buyer typically inherits. Here's what 310 CMR 15.301(7) actually says, what gets carried forward at closing, and the budget number buyers most often miss.

What 310 CMR 15.301(7) Actually Says

Under 310 CMR 15.301(7), the inspector may issue a conditional pass when the system is currently functioning but has one or more identified deficiencies that, while not constituting current failure under 15.303, will require correction or further evaluation within a specified timeframe — typically 24 months from the inspection date.

The structure: the inspector documents the deficiency on Title 5 inspection report, specifies the corrective action and timeframe, and files the report with the BOH within 30 days under 310 CMR 15.301(5). The clock starts the day the inspector signs the report, not the day of the property closing.

A conditional pass is not:

• A pass with cosmetic notes
• A "good for now" rating
• A failure waiting for paperwork
• An obligation that stays with the seller

It is a documented deficiency that the next owner — i.e., the buyer at sale — typically inherits as a re-inspection or repair obligation. The BOH tracks it. The file gets pulled.

The Deficiencies That Trigger Conditional Pass

Under 310 CMR 15.302(3), inspectors classify findings into categories. The ones that produce conditional pass rather than fail tend to be the wear-and-tear items that aren't yet causing functional failure:

• D-box settled but not bypassed. One outlet 0.5–1 inch low, no surfacing, lateral bias detectable but not severe. Re-leveling required within the conditional period.
• Tank baffle deteriorated, not yet missing. The cast-in concrete baffle has spalled but is still partially intact. Solids are mostly retained. Replacement required, not yet emergent.
• Effluent filter absent on a tank that should have one per as-built. Documented deviation from design, requires installation.
• Liquid level approaching outlet invert, not above. SAS hydraulic load is high, observation pit shows ponding that draws down within 60–90 minutes after flow stops. Re-inspection at 24 months to evaluate progression.
• Tank thinning at corrosion zone, not yet structural. Probe shows wall thickness 1.5–2.5 inches on a 4-inch wall. Replacement deferred but documented.

What does not produce conditional pass: any 310 CMR 15.303(1) failure criterion. Surfacing effluent, well setback violation, SHGW within 4 feet of SAS — those are fails, not conditionals. If your inspector wrote "conditional pass" with a 15.303 finding listed, the report is wrong and the BOH will reject it.

Why It's a Trap at Sale

The closing table dynamic is the core of the problem. The seller's agent presents the Title 5 inspection report cover with "Conditional Pass" highlighted. The buyer's agent confirms the lender accepts it. The lawyer doesn't read past the first page. The buyer signs.

What the buyer didn't read: the deficiency list on page 3 specifying "replace deteriorated tank baffle within 24 months from inspection date" and "verify effluent filter installation within 12 months."

Eighteen months later, the BOH agent sends a certified letter referencing the file and the upcoming deadline. The buyer — who has owned the house for 14 months at this point — discovers they're on the hook for $1,200–$4,500 of corrective work plus a re-inspection fee, with a hard deadline.

If the corrective work isn't completed within the timeframe, the BOH can issue an order to upgrade under 310 CMR 15.305. Non-compliance with that order can result in fines under MGL Chapter 111 §31, and the deficiency converts from conditional to failed status — meaning the next sale requires the upgrade before transfer.

What Buyers Should Do Before Closing

The conditional pass is negotiable. Three concrete moves:

• Read the deficiencies page. Title 5 inspection report lists each deficiency with the 15.302/15.303 subsection cited. Get that page, not just the cover. "Tank baffle deteriorated — replacement required within 24 months" is a $400–$1,200 line item plus a $300–$500 inspector return visit.
• Get a written cost estimate. Most NEIWPCC-certified inspectors will give a phone estimate of corrective cost on a system they just inspected. Get it in email; use it in negotiation.
• Negotiate a credit or pre-closing repair. Cleanest outcome: seller credits the buyer the documented cost. Round up — $4,000 if the inspector says $2,000–$3,000, because BOH-driven re-inspection adds administrative cost. The alternative: seller completes the work pre-closing and files a corrected Title 5 inspection report showing a clean pass. Adds 4–8 weeks but eliminates downstream exposure.

What to avoid: accepting the conditional pass with no concession. The buyer is signing up for a future BOH letter, a future bill, and the same paperwork at their eventual resale.

The 24-Month Re-Inspection: What It Costs

If the buyer inherits the conditional pass without a credit, budget over the 24-month window for:

• Corrective work. $400–$1,200 D-box re-leveling, $600–$1,800 baffle replacement, $80–$200 effluent filter, $1,500–$4,500 SAS jetting, $8,000–$18,000 if a structural upgrade is the real fix.
• Re-inspection. $400–$700 by a NEIWPCC-certified inspector, plus a $50–$200 BOH filing fee.
• Documentation overhead. $200–$400 if the inspector handles updating the as-built and BOH file.

Realistic budget: $1,500–$3,500 for minor deficiencies, $5,000–$9,000 moderate, $10,000+ if the conditional was masking a deferred structural issue that progressed.

What Triggers Conditional → Failed Conversion

Three things turn the conditional into a hard fail before the deadline:

• The deficiency progresses (D-box now fully bypassed, tank baffle now missing entirely, SAS now surfacing).
• The 24-month deadline passes without corrective work.
• A change of use at the property (added bedroom, new tenant, commercial conversion) triggers re-evaluation under 310 CMR 15.301(4).

Once converted, the system is failed and the upgrade obligation under 15.305 attaches. The corrective work is no longer optional.

How Complos helps

Conditional pass deficiencies are scattered across Title 5 inspection report in inspector-specific language; the BOH file abbreviates them further. Run the MA Title 5 compliance checker to parse a Title 5 inspection report conditional pass into the actual cited subsections, surface the corrective-action deadline, and produce the cost-range estimate to use in your closing negotiation. The tool also shows whether the deficiency is at risk of converting to a 15.303 failure within the 24-month window.
