What a Seller's Disclosure Is
The seller's disclosure is a standardized form, usually mandated by state law, in which the property owner answers questions about the home. The exact form varies by state, but most cover the same broad topics: structural history, water issues, environmental hazards, system ages, neighborhood factors, and any past insurance claims.
The seller signs the form, often under penalty of perjury, attesting that the information is true to the best of their knowledge. The phrase 'to the best of their knowledge' is doing a lot of work in that sentence. It limits the disclosure to what the seller actually knows. A seller who never went into the crawlspace genuinely does not know if there is moisture down there. A seller who bought the house six months ago has limited history to disclose. A seller who has lived there for forty years may know about issues that were repaired decades ago and forgotten.
What Disclosures Typically Cover
Most state forms ask about: roof leaks or repairs, basement or crawlspace water, structural movement or repairs, electrical or plumbing problems, HVAC issues, well or septic concerns, prior pest or rodent infestations, environmental hazards (lead paint, asbestos, radon), insurance claims, deaths on the property in some states, and pending lawsuits or assessments.
Federal law requires a separate lead-based paint disclosure for any home built before 1978, regardless of state requirements.
What Disclosures Do Not Cover
Disclosures do not cover anything the seller does not know. They typically do not require investigation. A seller is not obligated to test the air for radon, run a sewer scope, or open the electrical panel before completing the form. They write down what they remember and observe in normal daily life.
Some states allow sellers to opt out of completing a disclosure entirely by signing a waiver. Some states exempt certain sellers, such as estate sales or foreclosures, from disclosure requirements at all. Always check whether you actually have a usable disclosure for the property you are buying.
What an Inspection Report Is
An inspection report is a document produced by a licensed or certified home inspector after a multi-hour walk-through of the property. The inspector evaluates accessible systems, structures, and components against industry standards such as the ASHI Standards of Practice or InterNACHI Standards of Practice.
The report is based on direct observation. The inspector did not consult the seller's memory; they climbed into the attic, opened the panel, ran the water, fired the furnace, and looked at the foundation. Findings are limited to what the inspector could see and access. Things behind walls, beneath flooring, inside sealed components, or under heavy storage do not get inspected.
What Inspections Typically Cover
Standard inspections cover the roof, exterior, structure, electrical, plumbing, HVAC, attic, insulation, basement or crawlspace, interior surfaces, fireplaces, and built-in appliances. Many include specialty add-ons such as sewer scopes, radon tests, mold sampling, and termite inspections for additional fees.
What Inspections Do Not Cover
Standard inspections are non-invasive. The inspector does not cut into walls, dig up the yard, drain the water heater, or move heavy furniture. They cannot diagnose defects that are concealed or that only manifest under specific conditions. A roof that leaks only during driving rain may pass a dry-day inspection. A sump pump that fails only during a power outage will not be caught when the house has power.
Where the Two Documents Conflict
The most useful exercise during the contingency period is to read both documents side by side and look for inconsistencies. Discrepancies are not always evidence of dishonesty. They can mean the seller forgot, did not know, or interpreted the question differently. But every inconsistency is worth a follow-up question.
Disclosure Says No, Inspection Says Yes
The disclosure marks 'no known basement water issues' but the inspection notes efflorescence, staining, and moisture meter readings on the basement walls. This could mean the seller honestly did not notice. It could mean the issues developed after the seller bought the home and they did not consider them worth disclosing. It could also mean the seller is hoping you will not ask. The right move is to ask, in writing, with the photos attached.
Disclosure Says Yes, Inspection Misses It
The disclosure mentions a previous roof leak that was repaired in 2019, but the inspection report does not flag any roof concerns. This usually means the repair held and there is nothing currently visible. Worth confirming with your inspector, but not always a problem.
Both Silent on Something Significant
The most concerning gap is when something neither document addresses. If the property is on a septic system and the disclosure says the system was last pumped four years ago and the inspection report does not include a septic evaluation, you are buying a major system completely unevaluated. This is when you order a separate specialty inspection.
Legal Weight and Recourse
The two documents have different legal implications if problems surface after closing. A seller who knowingly misrepresents a known defect on a disclosure may be liable for fraud or breach of contract in many jurisdictions. The standard is generally that they knew about it and concealed it. Proving that knowledge after the fact is difficult but not impossible.
An inspection report has more limited recourse. If the inspector missed something they should have caught, your remedy is generally against the inspector, not the seller. Most inspection contracts limit liability to the cost of the inspection itself. State licensing boards can hear complaints, and some states have additional consumer protections, but recovering significant damages from an inspector is rare.
How to Use Them Together
Before your inspection, read the disclosure carefully and highlight items the seller mentioned: past repairs, system ages, ongoing issues, environmental tests. Bring those highlights to the inspector and ask them to pay particular attention to those areas. A disclosure that mentions a 2018 roof repair gives the inspector a specific area to evaluate more closely.
After the inspection, compare findings against the disclosure. Items in both are confirmed. Items in only the inspection are conditions the seller may not have known about. Items in only the disclosure are history that the inspection cannot evaluate but you should ask about. The combined picture is more accurate than either document alone.
The Bottom Line
Treat the disclosure as a starting point. Treat the inspection as the verification. Neither document is complete on its own. The seller cannot tell you what they do not know. The inspector cannot tell you what they cannot see. Together they give you a reasonable picture, and reasonable is the best you can hope for when buying a building someone else has lived in for years.
