A home inspection report is a written record of the physical condition of a house at a single point in time, produced after a licensed or certified inspector walks the property, tests accessible systems, and documents what they find. It typically runs 30 to 60 pages, includes photographs, and lands in your inbox within 24 to 72 hours of the walkthrough. For most buyers it arrives during the inspection contingency period and becomes the factual basis for deciding whether to proceed, renegotiate, or cancel the contract.
What the Report Covers
A standard inspection is a visual, non-invasive examination of a home’s major systems and structural components. Under the American Society of Home Inspectors (ASHI) Standard of Practice, the inspector evaluates readily accessible, visually observable, installed systems and flags items that are not functioning properly, significantly deficient, unsafe, or near the end of their useful life.
The core systems examined typically include:
- Structure: foundation walls, floors, ceilings, and roof framing for settlement, cracking, or water damage.
- Roofing: shingle condition, flashing, gutters, and signs of leaking.
- Electrical: panel capacity, wiring type, grounding, and outlet function.
- Plumbing: supply lines, drain function, water heater, and visible leaks.
- HVAC: heating and cooling operation, age, and condition of ductwork.
- Exterior: siding, grading around the foundation, driveways, and walkways.
- Interior: windows, doors, floors, walls, and ceilings in accessible rooms.
The inspector runs faucets, tests outlets, cycles the furnace and air conditioning, flushes toilets, and opens accessible panels. Each deficiency is photographed and located so you can find it yourself or hand it off to a contractor. The on-site portion usually takes two to four hours for a typical single-family home. Most inspectors encourage buyers to attend, which lets you see issues firsthand and ask questions on the spot.
What the Report Doesn’t Cover
The report is not a guarantee that nothing is wrong with the house. A standard inspection is explicitly not technically exhaustive. Inspectors cannot see behind walls, under floors, or inside sealed systems. They don’t move furniture, pull up carpet, or disassemble components. If a defect isn’t visible or accessible during a normal walkthrough, it won’t appear in the report.
Hidden problems that existed at the time of inspection but weren’t visible are called latent defects. A corroded pipe inside a wall, mold behind drywall, or a cracked sewer line underground all fall into this category. These are not inspector failures. The report is a snapshot of what could be seen and tested on that particular day, and the pre-inspection agreement spells that out.
Several categories sit outside a standard inspection entirely and require separate services:
- Environmental hazards such as radon, mold, asbestos, and lead paint.
- Pest and termite damage, usually handled by a licensed pest control company.
- Underground sewer lateral lines, which require a camera scope.
- Pool and spa equipment, which many inspectors treat as an add-on if they offer it at all.
- Code compliance. Inspectors report on condition and function, not whether the home meets current building codes. Unpermitted work may be noted if visible, but a code audit is a different service.
These boundaries tell you where risk still sits after a clean report. If the house was built before 1978, has a basement, or sits on clay soil with mature trees near the sewer line, those exclusions should prompt specialized testing before you close.
How to Read the Report
At 30 to 60 pages, the report can feel overwhelming if you try to weigh every line equally. The key is sorting findings by severity. Labels vary by inspector, but the tiers are consistent:
- Safety concerns: immediate risks to occupants, like exposed wiring, a gas leak, missing handrails on elevated stairs, or a water heater lacking proper venting. Address these before you move in, regardless of how negotiations go.
- Major defects: expensive problems affecting structural integrity or core systems. A failing roof, foundation cracks with active movement, or a furnace at the end of its life with a cracked heat exchanger. These are the findings that drive repair negotiations.
- Repair items: functional problems that need attention but aren’t emergencies. A leaking faucet, a sticking window, a bathroom fan vented into the attic instead of outside. Worth noting, sometimes worth negotiating, rarely deal-breakers.
- Maintenance and cosmetic items: peeling paint, failing caulk, minor grading issues. Every lived-in house has these, and they rarely factor into negotiations.
Read the summary page first if the report has one. Then focus on the safety and major defect sections, because those shape your purchase decision and your negotiating leverage. The photographs attached to each finding make it easy to pull contractor estimates for anything you want priced out before responding to the seller.
Specialized Inspections to Order Alongside the Standard Report
Radon Testing
Radon is a naturally occurring radioactive gas that seeps into homes through foundation cracks. It can’t be seen or smelled, so it requires a separate test. The EPA recommends action to reduce radon at or above 4 picocuries per liter (pCi/L) and suggests considering mitigation between 2 and 4 pCi/L.1National Center for Biotechnology Information. Indoor-Radon Guidelines and Recommendations During a transaction, short-term tests of two to seven days are most common. The device sits in the lowest livable area under closed-house conditions, meaning windows and exterior doors stay shut except for normal entry and exit. If results come back at 4 pCi/L or higher, a mitigation system can usually bring levels down.
Wood-Destroying Organism Reports
A wood-destroying organism (WDO) report looks for termites, carpenter ants, wood-boring beetles, and fungal rot that can compromise structural timber. These are usually performed by licensed pest control professionals rather than general home inspectors. Many lenders require a WDO report as a financing condition, particularly on VA and FHA loans. Standalone WDO reports typically cost $75 to $325.
Sewer Scope Inspections
A sewer scope sends a video camera through the lateral line connecting the house to the municipal sewer. Because that pipe is buried, a standard inspection can’t evaluate it. The camera reveals root intrusion, cracks, separations, deterioration, and slope problems that could lead to backups or excavation. Clay tile pipes installed before the 1970s are particularly vulnerable to joint separation and root penetration. A sewer scope generally runs $300 to $700 and can prevent inheriting a five-figure repair.
Mold and Air Quality Testing
A standard report may note visible mold or moisture conditions that invite it, but inspectors don’t test for mold. A dedicated mold inspection uses air sampling, surface tape lifts or swabs, and sometimes bulk material sampling, all analyzed in a lab. Results identify the type and concentration of mold present. This is worth considering if you see water staining, smell musty odors, or if anyone in the household has respiratory sensitivities.
What to Do After the Report Arrives
Most purchase contracts include an inspection contingency, commonly 7 to 10 days, during which you can complete the inspection, review the findings, and respond. You generally have three paths: ask the seller to make repairs, request a credit toward closing costs so you can handle the work yourself, or cancel the contract. A cancellation within a valid contingency period typically returns your earnest money, because the contingency is a contractual exit rather than a breach.
When negotiating, focus on safety hazards, major structural issues, and anything that may affect your financing. Those are the findings sellers are most likely to address and the ones with the most weight. Cosmetic complaints and normal wear rarely move the needle and can make you look unreasonable. A seller credit is often more practical than pre-closing repairs for mid-range issues, because it lets you choose the contractor and the timeline.
Market conditions shape strategy. In a seller’s market, asking for too much can kill the deal. In a buyer’s market, you have more room. The report gives you the factual foundation either way.
FHA and VA loans change the calculation. If the property doesn’t meet minimum property requirements, the seller may have to complete certain repairs before the loan can close, with the appraiser re-inspecting after the work. HUD publishes minimum property standards addressing durability and safety that go beyond a standard appraisal.2U.S. Department of Housing and Urban Development. Minimum Property Standards Resources Those aren’t optional negotiating items; they’re lender mandates.
How the Report Interacts With Seller Disclosures
Federal law requires specific disclosures when selling a home built before 1978. Under 42 U.S.C. ยง 4852d, sellers must tell buyers about any known lead-based paint or lead hazards, hand over any available lead inspection reports, provide the EPA’s lead hazard information pamphlet, and give buyers at least 10 days to arrange their own lead testing before the contract becomes binding.3Office of the Law Revision Counsel. 42 USC 4852d – Disclosure of Information Concerning Lead Upon Transfer of Residential Property The implementing regulation at 24 CFR 35.88 requires the seller to complete all disclosure activities before the buyer is contractually obligated.4eCFR. 24 CFR 35.88 – Disclosure Requirements for Sellers and Lessors The rule doesn’t force sellers to go looking for lead. It stops them from hiding what they already know.
Beyond lead, most states impose a broader duty on sellers to disclose known material defects. A material defect is generally one that significantly reduces property value or poses an unreasonable risk to occupants. Foundation problems, chronic water intrusion, environmental contamination, and major system failures qualify. A system being old or near the end of its expected life, on its own, does not. State approaches vary widely: some require detailed disclosure forms, others follow a “buyer beware” framework. The inspection report feeds directly into this. Once a defect appears in a report the seller has seen, it becomes a known condition for disclosure purposes going forward.
Limits on What the Report Can Do for You Later
Before the inspection, you’ll sign a pre-inspection agreement. Almost all of them contain a limitation of liability clause. The most common version caps the inspector’s total financial exposure at the cost of the inspection fee. Some set the cap at a higher fixed figure or a multiple of the fee. The practical effect: if the inspector misses a $30,000 foundation problem and the inspection cost $400, the contractual recovery may be $400.
Courts have upheld these clauses in many jurisdictions, though enforceability varies. Some states have invalidated caps set at the fee itself or imposed minimum thresholds. The clause also has to be conspicuous. If it’s buried in fine print without any formatting to flag it, a court is more likely to strike it down.
Latent defects give inspectors a natural defense regardless of the cap. Hidden defects by definition can’t be discovered through reasonable visual observation, so an inspector isn’t negligent for missing something no one could have seen. The strongest claim against an inspector arises when a defect was visible and accessible on the day of the inspection, should have been identified under the applicable standard of practice, and was missed or incorrectly reported.
The window for filing a claim depends on your state’s statute of limitations for negligence or breach of contract. The clock often starts when the defect is discovered rather than when the inspection happened, but some states and some contracts shorten that period. If you think your inspector missed something significant, talk to an attorney before the window closes.
Delivery, Cost, and Keeping the Report
Most inspectors deliver the final report within 24 to 72 hours of the on-site visit, usually as a digital document through a secure portal or encrypted PDF. The report becomes an official record once you acknowledge receipt, and you should keep it for as long as you own the home. It’s useful well past closing for tracking the age of systems, planning maintenance, and providing documentation when you sell.
For a standard single-family home, inspection fees generally fall between $300 and $600, averaging around $450. Price scales with square footage, age, and complexity. Add-ons stack on top: radon testing typically $125 to $300, a sewer scope $300 to $700, a standalone WDO report $75 to $325. Mold testing involves lab analysis and tends to cost more than radon. For a thorough look at an older home with a basement and mature landscaping, $700 to $1,200 for the inspection plus add-ons is realistic.
The fee is paid by the buyer at the time of service, not at closing. It’s a sunk cost whether or not the deal closes, which is why some buyers in competitive markets waive inspections to strengthen their offers. That’s a calculated gamble. For most buyers, a few hundred dollars for a thorough inspection is the cheapest insurance available in a six-figure transaction.
