Check the Township First
Because Act 537 devolves authority to municipalities, point-of-sale requirements vary. Some townships have adopted sewage management programs requiring inspection at transfer; many have not.
Call the local agency for the specific municipality — not the county, and not DEP — and ask two things: whether any inspection is required at transfer, and what records exist for the property.
Pull the Records
Ask the local agency for the permit file and any record drawings. That tells you when the system was installed, what type it is, where the components are, and what standards it was built to.
On older rural properties, sometimes no records exist at all. That is not automatically a dealbreaker, but it is worth knowing before closing rather than after — it means nobody can tell you what is buried or when it was last touched.

The Buyer’s Real Question
The question worth asking the local agency: does this property have a viable replacement area? A lot with nowhere to put a new absorption area is a lot where a failed system becomes a genuinely difficult problem.
For an older system on a constrained lot, that answer is worth more than the inspection report.
What Lenders Require
FHA and VA loans typically require evidence of a functioning system. Conventional lenders usually require a general home inspection, escalating to a septic-specific evaluation if concerns surface. Cash purchases carry no lender requirement, which is why failing systems often end up in cash-only sales.
For Sellers
Getting ahead of the inspection is almost always cheaper than reacting to it. A pre-listing inspection and pump-out is a modest, predictable cost. A deal collapsing at week six over a failed absorption area costs months of market time and a renegotiated price.
Practical preparation: pump the tank and keep the receipt, locate and mark the components, gather permits and record drawings, and disclose honestly. Pennsylvania requires disclosure of known material defects, and a documented, recently serviced system is a selling point rather than a question mark.
One Pennsylvania-specific advantage worth mentioning to a hesitant buyer: PENNVEST financing transfers the problem into manageable territory. A buyer worried about an aging system may feel differently knowing that a future replacement can be financed at 1.75 percent with no income limits.
Pennsylvania Septic Guide — Free Tool
Do You Qualify for a 1.75% Septic Loan?
Pennsylvania runs what may be the most generous septic financing program in the country, and hardly anyone knows it exists. The PENNVEST Homeowner Sewage Program lends up to $25,000 at 1.75% fixed for up to 20 years — with no household income limits at all.
Directional guidance only — PHFA and its participating lenders make the actual determination. Loans are secured and sized around your contractor’s estimate, so it helps to apply while collecting proposals. Debt-to-income generally needs to be at or under 45%. There is no minimum credit score, though payment history is reviewed. Minimum loan $2,500; no prepayment penalty.

Frequently Asked Questions
Does Pennsylvania require a septic inspection before selling?
There is no statewide requirement, but individual municipalities can impose their own under Act 537. Check with the local agency for the specific township.
What should I ask before buying a Pennsylvania home with septic?
Whether the property has a viable replacement area. An inspection tells you the system works today; it does not tell you what a replacement would cost if the site now requires a sand mound.
How do I get septic records for a property?
Ask the local agency for the permit file and any record drawings. On older rural properties no records may exist, which is worth knowing before closing.
What does a pre-listing septic inspection cost?
There is no published Pennsylvania figure for this. Whatever it comes to, it is considerably cheaper than a deal collapsing at week six over a failed absorption area.
