Before the inspection deadline starts running, confirm whether the house uses public sewer or septic and which township holds the permit. Pennsylvania does not require a septic test for every sale, but the contract, lender, buyer, or municipality may require one. Agree on the scope in writing.
Put the inspection scope in the sales contract
The agreement of sale should identify who selects the inspector, the intended standard, access responsibility, whether pumping or hydraulic loading is included, report deadline, and response rights. “Septic inspection” alone leaves room for a lid check when one party expected a full PSMA/NOF protocol.
PSMA says Pennsylvania has no law regulating on-lot inspection methods. Its standards fill an industry gap, but they are not DEP rules. If the contract requests a PSMA inspection, verify that the individual’s certification is current and that the provider will apply the complete current standard.
Get the township permit and pumping history
Ask the township for the permit, design basis, recorded repairs, pumping status, and open notices. West Lampeter, Pequea, Salisbury, Strasburg, Drumore, Warwick, and Martic each administer their on-lot programs differently. An overdue municipal report can remain an owner obligation even when the tank appears functional.
Compare the permit with current bedrooms and site improvements. A garage, pool, addition, or widened drive may occupy the reserved field or cross components. That conflict deserves SEO review rather than a private promise that paperwork can be fixed after closing.
What the buyer should receive
The report should identify system type, accessible tanks and chambers, distribution components, pumps and alarms where present, absorption-area observations, maintenance records, deficiencies, and limitations. Conclusions need plain explanations. A buyer should understand which finding calls for maintenance, further investigation, municipal repair approval, or a negotiated contingency response.
- Obtain the report before the contingency expires, not on settlement morning.
- Keep water-use instructions consistent with the chosen inspection method.
- Separate the inspector from any seller pressure to minimize access.
- Send proposed major repairs to the municipal SEO for permit direction.
What sellers can prepare without gaming the test
Collect permits, pumping reports, repair invoices, and alarm service records. Mark access covers and remove physical obstructions with permission. Disclose known defects through the transaction professionals. Do not pump immediately before the inspection unless the agreed protocol calls for it; an empty tank changes what the inspector can observe.
A seller should not promise that an old system meets today’s design code merely because it has no visible discharge. Existing permitted systems and new approvals are different questions. Let the report describe condition and the SEO address regulatory work.
When not to order a septic inspection
If utility records establish that the dwelling connects to public sewer, order the inspections relevant to the private lateral instead. Lancaster city’s wastewater bureau serves the city and parts of nearby townships. Confirm the account and physical connection rather than paying for a search for a tank that was never part of the property.
Local rules and service references
Rules and contacts can change. Check the current township record before relying on a deadline or form.
