Pennsylvania Seller Disclosure Form: A Buyer's Guide

Before you sign a purchase agreement in Pennsylvania, you're entitled to see the seller's disclosure statement. This is not optional — Pennsylvania's Real Estate Seller Disclosure Law requires sellers to provide it, and you have the legal right to rescind your offer within a specific window after receiving it.

The form is also not a complete picture of what you're buying. Understanding what it covers, what it legally doesn't have to include, and how to read it in combination with your home inspection is one of the most important skills a first-time Pennsylvania buyer can develop.

The Legal Framework: Pennsylvania's Seller Disclosure Law

Pennsylvania's Real Estate Seller Disclosure Law mandates that sellers of residential property disclose all known material defects affecting the property's value or desirability, or that the buyer would reasonably want to know. This applies to single-family homes, multifamily properties (up to four units), condominiums, and cooperatives.

The seller's disclosure is prepared using a standardized form, often the PAR Standard Form SPD (Seller's Property Disclosure Statement). While the law doesn't mandate a specific form, the Pennsylvania Association of Realtors form is used in the vast majority of transactions handled through licensed agents.

The disclosure must be provided to the buyer before or at the time of signing the Agreement of Sale. If you're making an offer through a buyer's agent, the disclosure is typically provided as part of the listing package — before you ever submit an offer. If it isn't, request it.

You have five business days after receiving the disclosure to rescind your offer, regardless of any contract terms. This rescission right exists under state law and cannot be waived in the contract. After that five-day window, your right to rescind based solely on the disclosure expires (though you retain your inspection contingency rights under Paragraph 13 of the Agreement of Sale for physical defects).

What the Disclosure Covers

The standard Pennsylvania seller disclosure form addresses the following categories:

Structural components: Foundation, basement walls and floors, crawl spaces, attic and roof. Sellers must disclose known water infiltration, structural damage, visible cracks, and previous repairs. Any history of settling, heaving, or movement of structural elements.

Mechanical systems: Heating system (type, age, known problems), central air conditioning, plumbing (supply and waste lines, water heater, any known leaks or corrosion), electrical system (panel type, known defects). Known problems with sump pumps, well pumps, or septic systems.

Environmental concerns: This section is particularly important in Pennsylvania given the state's specific hazards. Sellers must disclose:

• Prior radon testing results (elevated results must be reported; no prior testing is disclosed as "unknown")
• Known presence of lead-based paint on the property
• Known presence of asbestos
• Known presence of underground storage tanks (buried oil tanks)
• Any known environmental contamination of the property or immediate surroundings
• Mine subsidence history or claims against the property

Property boundary and legal status: Known encroachments, easements, rights-of-way, shared driveways, and deed restrictions. Whether the property is in a flood zone. HOA membership, fees, and any known pending assessments.

Neighborhood and neighborhood conditions: Known nuisances, neighborhood disputes, and proximity to registered sex offenders (this category varies by form version).

Defects repaired by the seller: Any repairs made to correct defects are disclosed, along with whether permits were obtained. Unpermitted work is a significant red flag that surfaces here.

What the Disclosure Does Not Cover

The seller's disclosure covers what sellers know — not what exists. This distinction is critical.

Sellers cannot disclose what they don't know. If a seller has never tested for radon, they honestly disclose "no prior testing." That doesn't mean the home has safe radon levels — it means the seller hasn't measured. This is exactly why professional radon testing during the inspection contingency is effectively mandatory in Pennsylvania, regardless of what the disclosure says.

The disclosure covers material defects, not conditions. A home built in 1920 has old pipes, old wiring, and an old roof. None of this requires disclosure under the material defect standard unless there is a known active defect. "Old but functional" is not a disclosure obligation.

Sellers are not required to investigate. Disclosure is based on actual knowledge, not constructive knowledge from an investigation a competent seller should have conducted. Sellers are not required to hire inspectors or test their own property before listing. They disclose what they know; they have no obligation to discover what they don't.

As-is sales: In some transactions, particularly estate sales and bank-owned REO foreclosures, sellers explicitly disclaim any knowledge of property conditions. These disclosures are often entirely "unknown" across all categories. Buyers in as-is transactions bear greater responsibility for their own due diligence because there is no reliable disclosure to cross-reference.

Pennsylvania-Specific Items to Focus On

Given the state's unique environmental profile, these sections of the seller disclosure deserve particular attention:

Radon: If the seller discloses prior elevated radon results, you have documentation for your remediation negotiation during the inspection period. If the seller discloses no prior testing, plan for your own test — the disclosure absence tells you nothing about actual levels.

Underground storage tanks: Older Pennsylvania homes, particularly those built before municipal gas line expansion in the 1950s through 1970s, frequently have buried heating oil tanks that were abandoned in place when natural gas service arrived. If the seller discloses a buried tank, investigate it thoroughly before closing. The remediation of a leaking buried oil tank can cost $15,000 to $60,000 or more in soil excavation and environmental cleanup.

Mine subsidence: For properties in the 43 Pennsylvania counties with documented mining history, any prior subsidence damage or claims must be disclosed. Prior subsidence claims don't necessarily disqualify a property — the PA DEP's Mine Subsidence Insurance program is designed specifically to cover ongoing risk. But undisclosed subsidence damage is a different matter.

Flooding history: Sellers must disclose known flooding of the basement or living areas. In suburban counties along creek corridors (Bucks County's Neshaminy Creek area, portions of Delaware County along Cobbs Creek), flooding history is material and affects both your homeowners insurance costs and your long-term property value.

Using the Disclosure Alongside the Inspection

The seller's disclosure is not a substitute for a professional home inspection. It's a complement. The inspection finds physical conditions; the disclosure provides the seller's explanation and history of those conditions.

When your inspector identifies something — say, fresh paint over a basement wall where water infiltration might have occurred — the disclosure becomes a cross-reference. Did the seller disclose prior water infiltration? If yes, the inspection and disclosure align. If no, and the evidence suggests prior water damage, you have a potential material misrepresentation issue.

During the inspection contingency negotiation, a seller's prior disclosure of a repaired defect often provides useful context. If the seller disclosed a replaced roof in 2019, and your inspector confirms recent high-quality roof work, that alignment is reassuring. If the seller didn't disclose the roof work but your inspector finds recent repairs and questions about quality, that discrepancy warrants further investigation.

Seller Misrepresentation and Remedies

If a seller knowingly misrepresents or conceals a material defect, they face liability under Pennsylvania law. Buyers who discover post-closing defects that should have been disclosed can pursue claims under the Real Estate Seller Disclosure Law and may also have claims under common law fraud or negligent misrepresentation theories.

In practice, proving that a seller had actual knowledge of a defect they failed to disclose is difficult. Sellers routinely claim they were unaware. Documentation helps — prior inspection reports discovered during due diligence, permits pulled for repairs, neighbor testimony — but legal action is expensive and outcomes uncertain.

The practical protection is thorough due diligence before closing: radon testing, full structural inspection, oil tank sweep in appropriate properties, title search for permits and liens, and a careful reading of the disclosure itself. Address concerns before closing through your inspection contingency, not after closing through litigation.

How to Read the Disclosure

Work through each section methodically with your buyer's agent. For every "yes" answer — seller is disclosing a known issue — ask:

• What specifically happened?
• Was it repaired? When? By whom?
• Were permits obtained?
• Is there documentation (receipts, inspection reports, contractor invoices)?

For every "unknown" answer on high-stakes items (radon, underground tanks, structural damage), treat it as a reason to investigate, not as a reason to feel reassured.

For every "no" answer, cross-reference against your inspection findings. Significant discrepancies between physical evidence and seller disclosure are negotiating leverage and potential legal flags.

The Pennsylvania First-Time Home Buyer Guide includes a full due diligence checklist that maps the seller disclosure categories against the inspection findings you should verify for each Pennsylvania-specific risk — radon, coal mine subsidence, underground storage tanks, and the municipal compliance certificate requirements.
