How to read a home inspection report (and what to do with it after)

What a home inspection report is

A home inspection report is the written result of a visual, non-invasive examination of a house's readily accessible systems and components: structure, roof, exterior, plumbing, electrical, heating and cooling, insulation and ventilation, and interiors. To read one, work backwards from the way it's laid out. Start with the lines saying a system was not inspected, then the sentences recommending further evaluation by a specialist, then the deficiencies with photos in the body, and finish with the summary page.

What the report is not is as important as what it is. It is not a warranty, an appraisal, a code-compliance inspection, or a promise that nothing will break next month. InterNACHI's Standards of Practice (last revised 2022) say the inspection is not technically exhaustive and exclude concealed conditions, code compliance, market value, insurability, and specialist matters. An inspection typically runs two to four hours; Angi's 2026 data puts the national average price at $344, with a typical range of $296 to $424. Most reports arrive within 24 hours, according to the inspection-software company Spectora.

There's one structural fact that explains most of the confusion people have with these documents. The checkbox is standardized. The judgment behind it is not. A state form can require an inspector to mark every item, but nothing requires two inspectors to see the same crack the same way, and, as you'll see below, at least one state form explicitly relieves inspectors of any duty to rank what they find. Read the report as one qualified person's observations, not as a verdict.

A report, walked through

Reports differ in layout, but the same handful of parts show up in all of them. Here's a sample walked through in reading order, from the cover metadata to the lines most people skim. Hover or tap any row to highlight it.

Two of those rows are the ones worth building a habit around. The NI lines tell you what nobody looked at. The “recommend further evaluation” lines tell you where the inspector's scope ran out and a specialist's begins. Everything else on the report is information; those two are open questions with money attached.

Reports also run on a small vocabulary of recurring phrases. Learn these six and most of a report decodes itself.

The checkbox is standardized. The judgment isn't.

If you're buying in Texas, your report is a state form. The Texas Real Estate Commission's REI 7-6 Property Inspection Report has been required for real estate inspections of one-to-four-family residential property in Texas since February 1, 2022, and it uses four boxes: I (Inspected), NI (Not Inspected), NP (Not Present), D (Deficient). The inspector indicates one of the four for each listed item and explains the findings in the corresponding section of the report.

The form defines Deficient as a condition that adversely and materially affects the performance of a system or component, or that constitutes a hazard to life, limb or property, as specified by the Commission's Standards of Practice. Then it says two things the rest of the form depends on.

First: items identified as Deficient “DO NOT obligate any party to make repairs or take other actions.” A D is a finding, not an instruction, and not leverage in itself. Second: the inspector is not required to prioritize or emphasize the importance of one deficiency over another. That single clause is the reason a report can feel apocalyptic. A missing outlet cover and a failing heat exchanger get the same checkbox, and the form is designed that way on purpose, because ranking severity is a judgment the regulator declined to require of inspectors.

A related consequence catches buyers of older homes: the D box is not a code-compliance finding, but the TREC form directs inspectors to report the absence of modern safety items even where the original construction was legal when built. Missing GFCI protection, missing safety glass, missing smoke or carbon monoxide alarms, stair balusters spaced too wide. A 1968 house can be entirely legal and still collect a page of deficiencies. The standard directs it, and a page of those items on an old house is normal.

Outside Texas, most inspectors work to the InterNACHI or ASHI standards and write narrative reports with no checkbox grid at all. And a third system shows up on many reports that people mistake for a standard: the S / R / D / F / AE letter codes generated by report-writing software. Those are a software convention. No association or state defines them, and two vendors can use the same letters differently.

Before you read a single finding, read the definitions page in your report. Whatever system it uses, the codes only mean what that document says they mean.

What “material defect” means on a home inspection report

“Material defect” is the term that decides what makes it into a report, and it's defined more narrowly than most buyers assume. InterNACHI's Standards of Practice require the inspector to report defects observed and deemed material by the inspector. California, which defines a home inspection by statute in Business and Professions Code §§7195–7199 while requiring no license to perform one, defines a material defect as a condition that significantly affects the value, desirability, habitability, or safety of the dwelling.

The two standards disagree here, and both are correct. InterNACHI's standards state plainly that a system or component “near, at, or beyond the end of its normal, useful life is not, in itself, a material defect.” Meanwhile ASHI's standard requires inspectors to report items that are not functioning properly, significantly deficient, unsafe, or near the end of their service lives. Together they explain why so many reports are full of age language on houses where nothing is broken.

Read an end-of-life note as a budgeting fact with a date on it, not as a red flag. A 22-year-old roof that isn't leaking is a scheduled expense; a roof that is leaking is a defect. Both belong in the report and they mean different things. Where the age note becomes a negotiation item is when the remaining life is short enough to land inside the first year or two of your ownership, and when a contractor's number puts a price on it. Where it becomes genuinely valuable is later: a report full of ages and remaining-life estimates is a capital-expense schedule for the house, if you can still find it.

The summary is not the report

Almost every modern report opens with a summary page, and almost every buyer negotiates off it. That page is the inspector's editorial selection from the body, not a standardized extract. Nothing defines what earns a place on it, and the TREC form goes further by stating that the inspector is not required to prioritize or emphasize one deficiency over another. Two inspectors looking at the same house can produce identical bodies and very different summaries.

The cost of stopping there is asymmetric. You negotiate off the summary, and then you own the body: the monitor notes, the age observations, the photo captions, the outbuilding nobody mentioned, and the NI lines. One 2019 analysis of inspection data by Porch found that 86% of inspections turn up at least one issue, with roofing the most common category at 19.7%. On a typical report there is far more in the body than on the summary. Spectora, whose software many inspectors use, puts the average at roughly 31 defects per report, though that figure is undated and vendor-published, so treat it as a rough sense of scale rather than a benchmark.

Read the body once, top to bottom, with a highlighter, before you read the summary. Then use the summary for what it's good at, which is a starting list for the repair conversation.

What wasn't inspected (the most expensive lines in the report)

The general inspection is visual and non-invasive. The inspector doesn't open walls, dig up yards, or dismantle equipment. Two categories of absence appear in every report as a result, and both are easy to read as reassurance when they are the opposite.

The first is the Not Inspected line: a crawl space blocked by storage, a panel that couldn't be opened safely, a roof too steep to walk, a unit that couldn't be tested because the outside temperature was too low. Nobody has told you that system is fine. They've told you nobody looked. If an NI lands on a foundation, a roof, an electrical panel, or a sewer line, getting it looked at is worth more than anything on the summary page.

The second is what the standard itself excludes. InterNACHI's Standards of Practice exclude concealed conditions, code compliance, market value, insurability, life-expectancy predictions, and specialist evaluation. In practice that means each of these is a separate inspection you have to order and pay for:

• Radon. EPA's A Citizen's Guide to Radon (2016 edition) estimates roughly 1 in 15 U.S. homes are at or above its 4 pCi/L action level, an estimate based on its national residential survey. A general inspection would not detect a single one of them.
• Wood-destroying insects (the NPMA-33 termite report), commonly required for VA loans.
• Sewer scope, the camera run from the house to the main. On an older home this is the inspection with the worst downside if skipped.
• Mold, asbestos, and lead paint, the last of which matters for any home built before 1978.
• Septic systems, wells, chimneys (a level 2 scan), and pools, each with its own specialist.
• Four-point and wind-mitigation inspections. In Florida it is often your insurer, not your lender, that asks. Your homeowners insurance policy can hinge on them.

The inspector isn't hiding any of this. The scope statement on the cover says it plainly. It's just that the exclusions are written as a paragraph of standards language and the deficiencies are written as a numbered list with photos, and people read the list.

Using the report to negotiate

The report itself gives you nothing. What gives you something is the contract clause the report is attached to: an inspection contingency, a due-diligence period, or, in Texas, a termination option under TREC's standard contract, where you pay an option fee for an unrestricted right to terminate. The length is a blank the parties fill in, the deadline is 5 p.m. local time on the stated day, and the option fee is not refundable. Whatever your state calls it, the same rule applies: the clock, not the findings, is what gives you leverage.

Work in that order. Read the report the day it arrives. Turn every “recommend further evaluation” line and every NI line into a phone call. Get written bids for the items you care about, because a contractor's number moves a seller and an inspector's adjective does not. Then choose your ask.

You generally have three currencies, and they aren't equivalent. A seller repair gets the work done before you own it, but you don't control who does it or how well. A closing credit or a price reduction puts the money in your hands and lets you hire your own contractor after closing, which is usually the better trade when the work is significant. Credits are often simpler for lenders than seller repairs, within limits your lender sets. Whatever you agree to, it becomes an amendment to the contract; a promise in a text message is not a repair agreement, and the credit needs to show up on your Closing Disclosure before you sign.

Once repairs are agreed, verify them. A re-inspection sends your inspector back to check the specific items, and the final walk-through before closing is your own last look. Ask for receipts and permits for anything a licensed trade was supposed to do. An agreement to repair is not evidence of a repair.

Two words worth separating. “As-is” in a listing signals that the seller does not intend to repair anything. It does not void your inspection contingency: you can still inspect, and you can still walk within your deadline. What changes is the likely answer, not your right to ask.

A pre-listing inspection is a different document. It is the seller's inspector, hired by the seller, on the seller's schedule, and it is a useful starting point rather than a substitute for your own. A pre-offer inspectionis yours, run before you write the offer, and it has grown rare. One regional brokerage's inspection partner reported that buyer pre-offer inspections fell from more than 10% of buyers in 2024 to under 4% in 2025, while pre-listing inspections more than doubled (Long & Foster newsroom, December 2025). That is one firm's book of business, not a national statistic, but it points at sellers doing the inspecting.

For a sense of how buyers behave: in NAR's July 2026 Realtors Confidence Index, 16% of buyers waived the inspection contingency, down from 20% a month earlier and 23% a year earlier (it was 18% in December 2025). Waivers are becoming less common, not more. If you have seen the “20% of winning offers waived the inspection” figure, that is Redfin's June 2020 read of four metros, and it still circulates; the national number to use is NAR's 16%. And a Clever survey of 986 buyers in June 2025 found 44% discovered problems after moving in that had not been disclosed, which is the quiet argument for reading the body of the report rather than the summary.

Four things worth knowing before you book

1. The inspector's liability is usually capped at the fee. Inspection agreements commonly contain a limitation-of-liability clause capping damages at the price of the inspection, and courts have upheld them, including the South Carolina Supreme Court. If a $400 inspection misses a $20,000 problem, the contract you signed generally limits your recovery to $400. Read the agreement before the inspection, not after, and check whether the inspector carries errors and omissions coverage.

2. A “walk-and-talk” is not an inspection report. Verbal-only walkthroughs have spread in competitive markets as a way to move fast. The mechanism is what matters: no written report means nothing to hand a contractor for a bid, nothing to attach to a repair amendment, nothing to reference at a warranty claim, and nothing to hold anyone to later. Whatever it's worth as reconnaissance, it produces no document, and this entire guide is about the document.

3. Your agent's recommended inspector is usually fine, and you should still get your own opinion. The referral relationship isn't sinister, but it does run through someone whose payday depends on the deal closing. Ask the inspector directly what they'll do if they find something serious, and read a sample of their reports before you book. A sample report tells you more about an inspector than any review does.

4. The “report is only good for 90 days” thing is folklore. No lender or agency rule sets an expiration on an inspection report the way FHA sets a 180-day validity window for appraisals (HUD Mortgagee Letter 2022-11). What actually expires is your contract deadline: the option or inspection period. Separately, the TREC form notes that repairs made after the inspection may render information in the report obsolete or invalid, which is the honest version of the idea: the report ages because the house changes, not because a clock ran out.

The report's second life, after closing

Granite reads 110 document types with 1,064 extraction fields (recounted September 1, 2026), and eight of them are property documents. Every one is anchored to a date the world assigned it. A deed has a recording date. A settlement statement has a settlement date. A survey has a survey date. A mortgage release has a release date. Those dates exist because somebody official wrote them down.

The inspection report has none of that. It is never recorded, never renewed, never refiled. It is also the one major home-purchase document missing from that list of 110, with no schema anywhere in our library. Nothing in a property file expires either, since deeds and surveys just accumulate; the inspection report is the one that gets thrown away. Buying a home touches nine document types across four separate filing categories, according to our analysis of how much paperwork a life generates, and the whole purchase runs 300 to 600 pages by one analysis from Leonard Baron, reported by Fox Business. The inspection report is the piece of that stack with the shortest official life and one of the longest useful ones.

The report keeps working long after the negotiation ends. Four ways, concretely:

• It's your baseline condition record. When you file an insurance claim for storm damage and the adjuster asks whether that roof damage predates the storm, the inspection report is dated third-party evidence of what the house looked like the week you bought it. Nothing else you own does that job.
• It's a maintenance and capital-expense schedule. Every remaining-life note is a line item with an approximate year attached. A report read once as a list of complaints reads later as a ten-year budget.
• It's a systems inventory. Ages, models, and serial numbers for the furnace, water heater, and appliances live in the body of the report. That's what a warranty claim, a rebate application, or a parts order needs, and it's usually easier to find there than on the equipment itself. Pair it with our home inventory checklist for the contents side.
• It may become a disclosure obligation when you sell. Texas REALTORS wrote in April 2023 that a broker or seller who receives an inspection report is charged with knowledge of the information in it, even if they never open it, and that material defects then have to be disclosed to later buyers. The Texas REALTORS seller's disclosure form (TXR 1406) asks sellers to attach inspection reports received in the past four years, though the statutory notice under Property Code §5.008 doesn't require it. Rules differ by state, and this isn't legal advice. But the report you filed away is a document you may be asked about years later.

Granite does that job, and it's worth being precise about the limits. Granite reads and files the documents you already have and makes them findable: drop in the inspection report with the closing packet and later ask what the inspector said about the water heater, or what year the roof was installed, and get the answer with a citation to the page it came from. It does not inspect houses, evaluate whether a deficiency is serious, negotiate with a seller, or give legal advice.

Put the report where you'll find it. Not in the closing folder, which nobody opens twice, but with the deed, the survey, the insurance policy, and the property tax bills, in whatever system you keep. The inspector looked at the structure; the surveyor looked at the boundary, and the survey is worth decoding while the closing folder is still open, so how to read a property survey walks that drawing element by element. Our guide to setting up a home filing system covers where property documents go, and how long to keep important documents has the retention table. Keep the inspection report for as long as you own the house, and then hand a copy along when you sell.
