Pennsylvania Seller Disclosure Law: What Sellers Must Reveal
Pennsylvania requires home sellers to complete a detailed property disclosure form before closing. The form — officially called the Seller’s Property Disclosure Statement — runs 14 pages and covers everything from roof condition to known environmental hazards. It’s one of the most thorough seller disclosure requirements in the country, and it exists to protect buyers from hidden defects that could cost thousands to repair after settlement.
Sellers who skip disclosures or lie on the form face real legal consequences, including rescission of the sale and liability for repair costs. Buyers who understand what the form covers — and what it doesn’t — are better equipped to evaluate a property and negotiate effectively. This guide explains every section of the Pennsylvania seller disclosure form, what sellers must reveal, and what buyers should watch for.
What Pennsylvania Law Requires
The Real Estate Seller Disclosure Law (68 Pa.C.S. 7301-7315) mandates that sellers of residential real property provide a written disclosure statement to the buyer before the signing of an agreement of sale. The law applies to most residential sales of one to four dwelling units, including single-family homes, duplexes, townhomes, and condominiums.
| Requirement | Details |
|---|---|
| Form | Standardized Seller’s Property Disclosure Statement |
| When delivered | Before signing the agreement of sale |
| Who completes it | The seller (not the agent) |
| Scope | Known material defects and conditions |
| Legal standard | Disclose what you know — not required to investigate |
| Applies to | 1-4 unit residential properties |
| Penalty for fraud | Buyer can rescind sale, recover repair costs, and pursue damages |
The critical word is “known.” Pennsylvania does not require sellers to hire inspectors or conduct investigations. Sellers must disclose defects and conditions they are aware of — but they cannot claim ignorance of obvious problems. A seller who has lived in a home with a leaking basement for five years cannot check “no known water problems” on the disclosure form and expect legal protection.
Exemptions: Who Doesn’t Have to Disclose
Several categories of sellers are exempt from the disclosure requirement:
- Estate sales: Transfers by a personal representative, executor, or administrator of an estate where the deceased was the owner
- Foreclosures and sheriff’s sales: Transfers pursuant to a court order, including bankruptcy sales
- First sales of new construction: Newly built homes sold by the builder (covered by implied warranty instead)
- Transfers between co-owners: Sales between spouses, between co-tenants, or pursuant to a divorce decree
- Transfers to or from government entities: Including eminent domain
- Transfers between family members: Parent to child, grandparent to grandchild
Estate sales are the most common exemption buyers encounter. When a homeowner dies and the estate sells the property, the executor typically hasn’t lived in the home and may not know its condition. In these cases, the disclosure form either isn’t provided or is marked with “unknown” for most items. Buyers should budget for a particularly thorough inspection when purchasing an estate property.

What the Disclosure Form Covers
The Pennsylvania seller disclosure form is organized into sections covering every major system and condition of the property. Here’s what each section addresses and what buyers should pay attention to:
Section 1: Seller Information and Property Details
Basic information about the property — address, type (single-family, duplex, etc.), year built, how long the seller has owned and occupied the property. The occupancy duration matters: a seller who has lived in the home for 20 years has far more knowledge of its quirks than someone who bought it as an investment two years ago and never lived there.
Section 2: Roof and Attic
| Disclosure Item | What Sellers Must Reveal | Why It Matters |
|---|---|---|
| Roof age | Year installed or last replaced | Asphalt shingle life in PA: 20-30 years depending on quality |
| Roof leaks | Any current or past leaks, even if repaired | Repaired leaks can recur; past water damage may be hidden |
| Roof material | Asphalt, slate, metal, tile | Affects maintenance costs and insurance rates |
| Ice dam history | Known ice dam damage or remediation | Common in PA winters; indicates insulation/ventilation issues |
| Attic insulation | Type and condition if known | Affects heating costs — significant in PA’s cold climate |
Pennsylvania’s freeze-thaw cycles and heavy snowfall make roof condition especially important. A roof nearing end of life on a home you’re buying means a $8,000-$15,000 replacement within a few years. See our PA roofing cost guide for current pricing by material.
Section 3: Basement and Foundation
| Disclosure Item | What Sellers Must Reveal | Red Flags for Buyers |
|---|---|---|
| Water infiltration | Any history of water in basement, seepage, or flooding | “Repaired” waterproofing may indicate chronic issues |
| Foundation cracks | Visible cracks, structural repairs, or professional assessments | Horizontal cracks are more serious than vertical settling cracks |
| Sump pump | Presence, age, and operation of sump pump | A sump pump means the home has a water management issue |
| Drainage systems | Interior or exterior drain tile, French drains | These systems were installed because water was a problem |
| Basement finishing | Whether basement was professionally finished with permits | Unpermitted finished basements can hide water/mold issues |
Basements are Pennsylvania’s most litigated disclosure issue. The state’s clay soils, high water tables, and older housing stock create persistent water infiltration problems. A seller who checks “no water problems” when there’s clearly a sump pump running is making a disclosure that doesn’t hold up to scrutiny. Buyers should always get a detailed inspection. Our PA home buying guide walks through the full inspection process.
Section 4: Termites and Wood-Destroying Insects
Sellers must disclose known termite damage, past treatments, and whether the property is under an active termite warranty or treatment contract. Pennsylvania is in a moderate-to-high termite risk zone — subterranean termites are present statewide, with the highest activity in the southeastern counties. A WDI (wood-destroying insect) inspection typically costs $75-$150 and is required by most mortgage lenders.
Section 5: Plumbing, Electrical, and HVAC
| System | What Must Be Disclosed | PA-Specific Concerns |
|---|---|---|
| Plumbing | Material (copper, galvanized, PEX, lead), known leaks, water pressure issues | Pre-1950 homes may have lead supply lines; some municipalities require lead testing |
| Sewer/septic | Connection type, septic tank location and last pumping, known sewer line issues | Older sewer laterals in PA cities are prone to root intrusion and clay pipe collapse |
| Water source | Municipal, well, or spring; water quality issues | ~20% of PA homes use private wells; well water requires testing for bacteria, nitrates, and radon |
| Electrical | Service size (100/150/200 amp), known issues, panel brand | Federal Pacific and Zinsco panels (common in 1960s-80s PA homes) are fire hazards |
| Heating | Type, fuel, age, last service date | Oil heat common in eastern PA; conversion to gas/heat pump is $5,000-$12,000 |
| Cooling | Central AC, window units, age of system | Older PA homes often lack central air — adding it costs $4,000-$8,000 |
Heating system disclosure is particularly important in Pennsylvania because of the state’s cold winters and the prevalence of older, less efficient systems. A home with a 25-year-old oil furnace and an underground oil tank presents potential costs of $8,000-$15,000 for system replacement and tank removal. Budget for heating costs with our PA heating cost guide.
Section 6: Water and Sewage
This section covers the water supply source and sewage disposal method. For homes on public water and sewer, disclosures focus on known issues like water quality complaints or sewer backups. For homes with private wells and septic systems — roughly 20% of Pennsylvania homes, concentrated in rural areas — the disclosures are more detailed:
- Wells: Depth, flow rate, water quality test results, known contamination (bacteria, nitrates, radon in water, heavy metals)
- Septic systems: Type, size, age, last pumping date, any history of failure or repair, location of drain field
- Springs: Some rural PA homes use natural springs — sellers must disclose reliability and any seasonal flow issues
Section 7: Radon
Given Pennsylvania’s severe radon problem — approximately 40% of homes exceed the EPA’s 4 pCi/L action level — the disclosure form specifically addresses radon:
- Whether radon testing has ever been conducted
- Results of any radon tests (sellers must disclose all known results, not just the most recent)
- Whether a radon mitigation system has been installed
- The type and condition of any mitigation system
Sellers are not required to test for radon before selling. But if they have test results, they must disclose them — even if the results are unfavorable. Hiding known radon test results is a violation of the disclosure law. For a complete understanding of radon risk by county, see our PA radon guide.
Section 8: Environmental Hazards
| Hazard | Disclosure Requirement | PA Context |
|---|---|---|
| Lead paint | Federal law (not just PA): disclose known lead paint in pre-1978 homes | ~60% of PA housing stock built before 1978 |
| Asbestos | Known asbestos in insulation, floor tiles, pipe wrap, siding | Common in 1940s-1970s PA homes; removal costs $5,000-$20,000 |
| Mold | Known mold growth or past remediation | Basement moisture issues make mold common in PA |
| Underground storage tanks | Known presence, status (active/abandoned), any contamination | Abandoned oil tanks are common in eastern PA; removal costs $1,500-$3,500 |
| Contaminated soil/water | Known soil or groundwater contamination from any source | PA’s mining and industrial history creates localized contamination |
| Nearby hazards | Knowledge of landfills, industrial sites, or environmental cleanup sites | EPA Superfund sites exist in multiple PA counties |
Lead paint disclosure deserves special attention because it’s governed by federal law (the Lead-Based Paint Disclosure Rule) in addition to Pennsylvania’s disclosure requirements. For any home built before 1978, the seller must provide a specific lead paint disclosure form, give the buyer a copy of the EPA pamphlet “Protect Your Family From Lead in Your Home,” and allow 10 days for a lead inspection if the buyer requests one.
Section 9: Structural Issues
Sellers must disclose known problems with the home’s structural integrity:
- Settling, heaving, or movement of the foundation
- Wall, floor, or ceiling cracks (beyond normal settling)
- Additions or structural modifications and whether permits were obtained
- Fire damage and subsequent repairs
- Flood damage (whether or not insurance covered it)
- Any history of structural engineering assessments or repairs
In Pennsylvania, unpermitted additions are a significant issue, particularly in older communities where homeowners added rooms, decks, or finished basements without pulling permits. Unpermitted work can create problems with insurance coverage, future sales, and code compliance.
Section 10: Land and Property Issues
| Issue | What Must Be Disclosed | Why It Matters in PA |
|---|---|---|
| Boundary disputes | Any known disputes with neighbors over property lines | PA’s older subdivisions often have imprecise boundaries |
| Easements | Known utility, access, or conservation easements | Pipeline easements are common in western PA (Marcellus Shale) |
| Drainage | Surface water problems, grading issues, standing water | PA’s clay soils create persistent drainage challenges |
| Zoning violations | Known non-conforming uses or zoning violations | Many PA properties are “legal non-conforming” — grandfathered uses |
| HOA/deed restrictions | Existence of HOA, fees, rules, pending assessments | Planned communities in suburban PA often have HOA fees of $100-$400/month |
| Mining rights | Whether mineral/gas rights have been severed from surface rights | Critical in Marcellus Shale region; severed rights affect property value |
Mineral rights are a uniquely important Pennsylvania disclosure item. In western and northern PA, natural gas drilling rights (Marcellus Shale) have been separated from surface rights on many properties. A home where the mineral rights were sold or leased can be subject to drilling activity on or near the property — even against the surface owner’s wishes. Always verify mineral rights status through a title search.
Section 11: Legal Issues
Sellers must disclose pending litigation, code violations, and any notices from government agencies related to the property. This includes:
- Outstanding building code violations
- Notices from the municipality about property maintenance
- Pending or threatened lawsuits involving the property
- Tax liens or assessments (these would also appear in the title search)
- Homeowners association violations or pending special assessments
What Sellers Do Not Have to Disclose
Pennsylvania’s disclosure law has notable gaps. Sellers are not required to disclose:
- Deaths on the property: PA law explicitly states that deaths (including suicides and homicides) are not material defects that require disclosure
- Sex offender proximity: Sellers don’t need to disclose whether registered sex offenders live nearby (buyers can check Megan’s Law registry independently)
- Neighborhood nuisances: Noisy neighbors, barking dogs, and similar quality-of-life issues generally aren’t covered
- Future development: Sellers don’t need to disclose planned construction or development in the area unless they have specific knowledge of projects that would directly impact the property
- Defects they genuinely don’t know about: The standard is “known” defects — sellers aren’t expected to discover problems they haven’t experienced
This is why a professional home inspection is essential regardless of what the disclosure form says. The inspection reveals conditions the seller may not know about — or conditions they chose to interpret generously on the form.
The Disclosure Form in Practice
Understanding how the disclosure form actually works in a Pennsylvania real estate transaction:
Timing
The seller’s agent should provide the completed disclosure form to the buyer before the agreement of sale is signed. In practice, buyers sometimes receive it during the offer negotiation period. If the buyer receives the disclosure after signing the agreement of sale, they have five days to terminate the agreement without penalty after receiving the disclosure. This five-day right cannot be waived.
How to Read the Form
The form uses a three-option format for most items: Yes, No, or Unknown. Pay attention to these patterns:
| Pattern on Form | What It Likely Means | Buyer Action |
|---|---|---|
| Mostly “No” answers | Either a well-maintained home or a seller who isn’t being thorough | Verify with inspection; ask agent for clarification on suspiciously clean forms |
| Several “Unknown” answers | Seller may not have lived in home long, or is hedging | Inspect those areas carefully; “unknown” is legally safer for sellers than “no” |
| “Yes” with explanations | Seller is being transparent about known issues | Evaluate whether the disclosed issues are deal-breakers or manageable |
| Brief or vague answers | Seller may be minimizing issues | Ask for specifics in writing before signing the agreement |
Amendments
If the seller discovers a new defect between completing the disclosure and closing, they must amend the disclosure form. The buyer then has the same five-day review period to decide whether to proceed. Common amendments include issues discovered during the buyer’s inspection that the seller was genuinely unaware of — such as a failing septic system or elevated radon levels.
Common Disclosure Disputes in Pennsylvania
These are the most frequently litigated disclosure issues in Pennsylvania real estate transactions:
| Issue | Common Dispute | How Courts Typically Rule |
|---|---|---|
| Basement water | Seller says “no water problems” but evidence of past waterproofing exists | Waterproofing products are evidence of water history; non-disclosure likely fraudulent |
| Foundation cracks | Seller claims cracks are “cosmetic” when they’re structural | If seller had a structural assessment done, they must disclose it regardless of their opinion |
| Roof age | Seller claims roof is “10 years old” but it’s 20+ | Affirmative misstatement on disclosure form is fraud |
| Mold | Seller painted over mold without disclosing or remediating | Concealment of known defect; buyer entitled to remediation costs |
| Sewer lateral | Seller knew about sewer line problems but didn’t disclose | If seller had plumbing work done on the lateral, they had knowledge |
| Septic system | Seller claims system is “functioning” when it’s failing | Seller’s pumping records and maintenance history are relevant evidence |
Buyer Remedies When Sellers Don’t Disclose
If you discover that a seller failed to disclose a known defect, Pennsylvania law provides several remedies:
- Before closing: Terminate the agreement of sale during the five-day review period after receiving (or amending) the disclosure. Full deposit refund.
- After closing — repair costs: Sue the seller for the cost of repairing the undisclosed defect. You must prove the seller knew about the defect and failed to disclose it.
- After closing — rescission: In extreme cases (intentional fraud, major structural defects), courts may allow rescission — unwinding the entire transaction. This is rare and requires proof of intentional concealment.
- Statute of limitations: You generally have two years from the date you discover (or should have discovered) the defect to file a claim.
The burden of proof is on the buyer. You must show that the seller knew about the defect and intentionally failed to disclose it. This is easier when there’s documentation — repair invoices, contractor estimates, insurance claims, or previous inspection reports that show the seller had knowledge. Plan your budget for potential repair costs with our PA renovation cost guide.
Tips for Buyers Reviewing Disclosures
- Read the form before your inspection. Give the disclosure to your inspector and ask them to pay special attention to any “yes” or “unknown” items. Your inspector can verify or investigate the seller’s claims.
- Cross-reference with the listing. If the listing says “new roof in 2020” but the disclosure says the roof is from 2015, ask for clarification in writing.
- Ask about repairs. Any “yes” answer should include documentation. If the seller says “past water issue — repaired,” ask for the contractor’s name, date of repair, and warranty information.
- Check for permits. Disclosed renovations should have corresponding permits on file with the municipality. Your agent can help verify this.
- Don’t rely solely on the disclosure. It covers only what the seller knows (or admits to knowing). A professional inspection is essential — it reveals issues the seller may not be aware of. Factor inspection costs into your closing cost budget.
- Get a radon test. Even if the seller discloses no known radon issues, test anyway. Radon levels can change over time, and Pennsylvania’s geology makes testing essential in every transaction.
- Consider a sewer lateral inspection. For homes built before 1970, a camera inspection of the sewer lateral ($250-$400) can reveal clay pipe deterioration or root intrusion that the seller may not know about.
Tips for Sellers Completing Disclosures
- Be honest. Disclosure fraud is the number one source of post-closing real estate lawsuits in Pennsylvania. The cost of honesty is almost always less than the cost of litigation.
- When in doubt, disclose. If you’re unsure whether something is a “defect,” disclose it anyway. Over-disclosure protects you legally. Under-disclosure creates liability.
- “Unknown” is acceptable. If you genuinely don’t know the answer to a question, mark “unknown.” This is legally safer than guessing “no.”
- Keep records. Save all contractor invoices, inspection reports, and repair documentation. These records support your disclosures and protect you if a dispute arises.
- Complete the form yourself. Don’t let your agent fill out the disclosure form for you. The seller — the person with actual knowledge of the property — must complete it.
- Disclose repairs, not just problems. A repair is evidence that a problem existed. Disclosing both the problem and the repair is more transparent and legally protective than disclosing neither.

Pennsylvania-Specific Disclosure Considerations
Oil Tanks
Underground oil storage tanks are common in eastern Pennsylvania homes built before natural gas service was widely available. These tanks — typically 275 to 1,000 gallons — were buried in yards and connected to oil-fired heating systems. Many have been abandoned in place when homes converted to gas or electric heat. Sellers must disclose known underground tanks, whether active or abandoned. Abandoned tanks can leak, contaminating soil and groundwater. Tank removal costs $1,500-$3,500; if contamination is found, remediation can cost $10,000-$50,000 or more.
Mining Subsidence
In western Pennsylvania’s coal country — particularly Allegheny, Washington, Greene, Fayette, and Westmoreland counties — underground mine voids can cause surface subsidence. Sellers must disclose known mine subsidence damage or proximity to known mine workings. Pennsylvania has a Mine Subsidence Insurance program (offered through the PA Department of Environmental Protection) that provides up to $75,000 in coverage for mine subsidence damage. This insurance is available in mine-prone areas for approximately $100-$300 per year.
Marcellus Shale Gas Leases
In northern and western Pennsylvania, many properties have active or expired natural gas leases on the mineral rights. Sellers must disclose known gas leases, royalty agreements, and whether mineral rights are included with the surface rights. A property with severed mineral rights may be subject to drilling activity, pipeline easements, or compressor station proximity — all of which affect property value and quality of life.
Historic District Restrictions
Properties in Pennsylvania’s historic districts (common in Philadelphia, Pittsburgh, Lancaster, Bethlehem, and many smaller boroughs) are subject to design review requirements that restrict exterior modifications. Sellers should disclose historic district status, though technically it’s public information. Buyers in historic districts may face higher renovation costs due to material requirements and approval processes.
The Role of Real Estate Agents in Disclosure
Pennsylvania real estate agents have their own disclosure obligations, separate from the seller’s. Under the Real Estate Licensing and Registration Act, agents must disclose material defects they personally know about — even if the seller hasn’t disclosed them. If a listing agent notices a crack in the foundation during a walkthrough, the agent must disclose it to potential buyers regardless of what the seller put on the disclosure form.
Buyer’s agents should review the disclosure form with their clients, flag any concerning items, and recommend appropriate inspections. A good buyer’s agent will also notice inconsistencies between the disclosure and the property’s actual condition during showings.
Disclosure and Your Purchase Budget
The disclosure form isn’t just a legal document — it’s a budgeting tool. Every “yes” answer represents a known condition that may affect your ownership costs. Use the disclosure to estimate potential repair or maintenance costs and factor them into your purchase decision:
| Disclosed Issue | Potential Cost to Address | Urgency |
|---|---|---|
| Roof over 20 years old | $8,000-$15,000 replacement | Within 5 years |
| Past basement water issues | $3,000-$10,000 waterproofing | Before finishing basement |
| Radon above 4 pCi/L | $800-$1,500 mitigation | Before occupancy |
| Oil heat system 20+ years | $5,000-$12,000 replacement/conversion | Within 3-5 years |
| Septic system needing work | $3,000-$25,000 repair/replacement | Immediate if failing |
| Underground oil tank | $1,500-$3,500 removal; $10,000+ if contaminated | Before closing if possible |
| Electrical panel replacement needed | $2,000-$4,000 | Immediate for safety |
| Known termite damage | $500-$5,000 repair + $200-$400/year treatment | Immediate |
Factor these costs into your total purchase budget. Use our affordability calculator to determine how repair costs affect what you can comfortably spend, and the mortgage calculator to see your monthly payment.

Frequently Asked Questions
What must a seller disclose in Pennsylvania?
Pennsylvania sellers must disclose all known material defects on the standardized Seller’s Property Disclosure Statement. This covers roof condition, foundation issues, water infiltration, plumbing and electrical systems, heating and cooling, radon test results, environmental hazards (lead paint, asbestos, mold), structural problems, boundary disputes, easements, and legal issues. The standard is “known” defects — sellers must share what they know but aren’t required to investigate or test for problems they haven’t experienced.
Can a seller refuse to fill out the disclosure form in PA?
Most residential sellers cannot refuse — the Seller Disclosure Law requires completion of the form for sales of 1-4 unit residential properties. Exempt sellers (estates, foreclosures, new construction, family transfers) don’t have to complete it. If a non-exempt seller refuses to provide the disclosure, the buyer can terminate the agreement of sale. In practice, refusal is extremely rare and raises serious red flags about the property’s condition.
What happens if a seller lies on the disclosure form?
If a seller intentionally misrepresents or conceals a known defect, the buyer can pursue legal remedies after closing. These include suing for the cost of repairs, consequential damages, and in extreme cases, rescission of the sale. The buyer must prove the seller had actual knowledge of the defect and intentionally failed to disclose it. The statute of limitations is generally two years from discovery of the defect. Courts may also award attorney’s fees in cases of intentional fraud.
Does the seller have to disclose a death in the home?
No. Pennsylvania law (68 Pa.C.S. 7308) explicitly states that a death on the property — including from natural causes, suicide, or homicide — is not a material defect that requires disclosure. The same statute provides that the property being the site of a suspected haunting is not a disclosable condition. However, if you’re concerned, you can ask the seller directly — they’re not prohibited from answering, they’re just not required to volunteer the information.
Is radon disclosure required when selling a home in Pennsylvania?
Sellers are not required to test for radon before selling. However, if radon testing has been conducted, the seller must disclose all known test results and the existence of any mitigation system on the disclosure form. Hiding known radon test results is a violation of the disclosure law. Given that approximately 40% of Pennsylvania homes exceed the EPA action level, buyers should always conduct their own radon test during the inspection period regardless of the seller’s disclosures. Read our PA radon guide for testing details.
Do I need a home inspection if the seller disclosure looks clean?
Absolutely. The disclosure form only covers what the seller knows about. Hidden problems — failing sewer laterals, early-stage termite damage, electrical hazards behind walls, roof underlayment deterioration — won’t appear on any disclosure form because the seller doesn’t know about them. A professional home inspection ($350-$600) is the single most important step in any Pennsylvania home purchase. Add radon testing ($150-$300) and a sewer camera inspection ($250-$400) for older homes.
