What Does a Home Inspection Include?
Buying a home is one of the biggest financial decisions you’ll ever make. A thorough home inspection is your best tool for making sure you know exactly what you’re getting — before you sign on the dotted line.
A home inspection is a comprehensive, visual evaluation of a property’s condition performed by a licensed home inspector. It typically takes place after your offer is accepted but before closing — giving you critical information about the home’s systems and structure while you still have time to negotiate or walk away.
So, what does a home inspection include, exactly? Here’s a complete breakdown of every area inspectors examine, what they’re looking for, and why each one matters to you as a buyer.
What Inspectors Check — And Why It Matters
A standard home inspection covers all of the major components and systems of a home. Below is a detailed look at each area — what the inspector evaluates and why it’s important to your purchase decision.
- Structure & Foundation
The foundation is the most critical component of any home — it supports everything above it. Inspectors examine the foundation walls, floor joists, beams, and load-bearing walls for cracks, bowing, water staining, or signs of movement and settling. They’ll also look at the basement or crawl space if the home has one, checking for standing water, moisture intrusion, and wood rot.
Not all cracks are cause for alarm — hairline cracks are common in older homes — but horizontal cracks, stair-step cracks in masonry, or cracks wider than a quarter inch can signal serious structural movement that’s expensive to repair.
Why it matters to you: Foundation issues are among the most costly repairs a homeowner can face, often running $5,000–$30,000 or more. Catching them before closing gives you the opportunity to negotiate repairs or a price reduction — or to walk away from a money pit entirely.
- Roof
The roof inspection covers shingles or other roofing materials, the flashing around chimneys and vents (which prevents water from seeping in at joints), the soffit and fascia boards along the roofline, and the gutter system. Inspectors look for missing or curling shingles, exposed nail heads, worn flashing, sagging sections, and signs of past or active leaks on the underside of the roof deck.
They’ll also evaluate the overall age of the roof and estimate its remaining useful life. A standard asphalt shingle roof lasts 20–30 years; if the home has a roof nearing the end of that range, you’ll want to know upfront.
Why it matters to you: A new roof can cost $8,000–$20,000 depending on the home’s size and materials. Even minor roof damage can allow water into the attic and walls, leading to mold, rot, and damage to insulation and ceilings. Knowing the roof’s condition helps you budget accurately and negotiate confidently.
- Exterior
The home’s exterior is its first line of defense against the elements. Inspectors examine siding and trim for damage, rot, or gaps where moisture or pests could enter. Windows and doors are checked for proper sealing, operation, and any broken seals in double-pane glass (which shows up as fogging between panes).
Decks and patios receive attention for structural integrity, wood rot, and proper fastening. One often-overlooked area is the grading — the slope of the soil around the home’s perimeter. Ideally, the ground should slope away from the foundation to direct rainwater away from the home. Negative grading (soil sloping toward the foundation) is a leading cause of water intrusion in basements and crawl spaces.
Why it matters to you: Exterior issues can seem cosmetic but often mask deeper water damage or structural problems. A deck with rotted posts is a safety hazard. Improper grading can mean water in the basement every rainstorm. These are negotiating points — and safety considerations — worth knowing before you close.
- Plumbing System
Inspectors test every accessible faucet, toilet, and shower in the home, checking for leaks, proper drainage, and adequate water pressure. They examine the visible supply and drain pipes for corrosion, outdated materials (such as galvanized steel or polybutylene, both known to fail), and signs of past leaks or amateur repairs. The water heater is evaluated for age, condition, proper venting, and whether it’s up to current safety codes.
While inspectors can’t see inside walls, they look for telltale signs of hidden leaks — water stains on ceilings below bathrooms, soft spots in flooring near fixtures, and discoloration on walls near pipes. They’ll also note the main water shut-off location, which every homeowner needs to know.
Why it matters to you: Plumbing issues range from minor (a dripping faucet) to major (a whole-house re-pipe, which can cost $5,000–$15,000). Low water pressure, slow drains, or signs of past leaks can hint at bigger problems in the pipes you can’t see. Knowing the water heater’s age also helps you anticipate near-term replacement costs.
- Electrical System
The electrical inspection starts at the main service panel, where inspectors look for proper breaker sizing, signs of overheating or burning, double-tapped breakers (two wires connected to a single breaker — a fire risk), and whether the panel brand has known defect histories. They’ll test outlets throughout the home for proper grounding and polarity, and verify that GFCI (ground fault circuit interrupter) outlets are in place wherever code requires them — kitchens, bathrooms, garages, and outdoor areas.
Older homes may still have aluminum wiring (common in the 1960s and 70s) or knob-and-tube wiring, both of which present fire risks and often require remediation. Inspectors also check that the home’s electrical capacity is adequate for modern usage, and that all visible wiring is properly protected.
Why it matters to you: Electrical problems are a leading cause of house fires. Beyond safety, outdated electrical systems may be difficult or expensive to insure. Rewiring an older home can cost $8,000–$20,000. Identifying these issues before closing could save you significantly — both financially and in peace of mind.
- Heating & Cooling (HVAC)
The HVAC inspection evaluates the furnace and air conditioning unit, checking their age, condition, and whether they’re operating correctly. Inspectors run the system through heating and cooling cycles, listen for unusual noises, check the heat exchanger for cracks (a cracked heat exchanger can allow carbon monoxide to enter living spaces), and assess the condition of ductwork for leaks or obstructions. Filters, vents, and the thermostat are also checked.
The inspector will note the approximate age of both units. Most furnaces last 15–25 years; central air conditioners typically 10–20 years. Knowing where a system falls in that range is important for anticipating replacement costs.
Why it matters to you: A failing HVAC system is both uncomfortable and expensive to replace. A new central A/C unit runs $3,000–$7,000; a furnace replacement $2,500–$7,500. In St. George’s desert climate, a well-functioning cooling system isn’t a luxury — it’s a necessity. An aging or poorly maintained system is a strong negotiating point.
- Interior Areas
Inside the home, inspectors work room by room — examining walls and ceilings for cracks, staining, and signs of water damage; floors for soft spots, uneven surfaces, or damaged material; and doors and windows for proper operation, damaged hardware, and signs of moisture or drafts. Stairways and railings are checked for stability and compliance with safety standards.
Interior cracks often tell a story. A single crack above a door frame is common as homes settle, but multiple cracks in the same area, or diagonal cracks running from corners of windows and doors, can signal structural movement worth investigating further. Water stains on ceilings are always noted — even old stains, because they indicate a leak that may have been repaired or may still be active.
Why it matters to you: Interior issues can range from cosmetic (paint touch-ups) to significant (water damage requiring drywall replacement and mold remediation). What you see on the surface isn’t always the full picture. A trained inspector knows what’s normal and what warrants a closer look — giving you information a casual walkthrough simply won’t reveal.
- Attic & Insulation
The attic is one of the most telling spaces in any home. Inspectors look at the insulation type and depth — inadequate insulation drives up heating and cooling costs significantly. They check for proper ventilation (ridge vents, soffit vents, or attic fans), because a poorly ventilated attic traps heat in summer and moisture in winter, both of which shorten roof life and can cause mold growth.
The roof structure is visible from the attic — rafters and sheathing are inspected for signs of sagging, water damage, staining, or evidence of past leaks. Inspectors also look for signs of pest activity, especially wood-boring insects like carpenter ants or termites, whose damage is often most visible in the attic framing.
Why it matters to you: Attic problems are hidden from view during a standard showing, yet they can have a major impact on your comfort, energy bills, and the long-term health of the roof. Discovering inadequate insulation or ventilation before closing lets you factor those costs into your offer and budget.
- Appliances
If appliances are included in the sale — which is common and should be spelled out in the purchase agreement — inspectors will test them for basic functionality. This typically includes the range and oven (burners, bake/broil functions), the dishwasher (a full cycle is often run), the garbage disposal, and built-in microwave. Refrigerators are sometimes checked as well, particularly the ice maker and water dispenser if present.
Inspectors aren’t appliance repair technicians, so their evaluation is functional rather than diagnostic. They’ll note if something doesn’t turn on or run a cycle — but a full appliance inspection goes beyond the scope of a standard home inspection.
Why it matters to you: Appliances you expect to inherit with the home should actually work. A non-functioning oven or dishwasher discovered after closing is an unwelcome and avoidable surprise. If appliances are older or near end of life, that’s worth factoring into your negotiation.
- Garage
The garage inspection covers the structural condition of the space, the operation of the garage door (including auto-reverse safety sensors, which are required by code on all automatic openers), and the condition of the door between the garage and living space. That interior door is actually a fire-safety element — it’s required to be fire-rated and self-closing to slow the spread of flames or fumes from the garage into the home.
Inspectors also look for signs of moisture, improper storage of flammable materials, and adequate ventilation. In attached garages, they verify that the attic above the garage is properly fire-separated from the rest of the home’s attic space.
Why it matters to you: A garage door that doesn’t auto-reverse is a safety hazard — especially in homes with children. Missing fire separation between the garage and living space can create serious liability and insurance concerns. These details are easy to overlook but important to have on record before closing.
What’s Usually Not Included
A standard inspection is a visual assessment — thorough, but not exhaustive. Inspectors won’t open walls, move belongings, or perform specialized tests unless you arrange for them separately. Items typically excluded include:
- Mold testing
- Radon detection
- Pest and termite inspections
- Sewer line scopes
- Chimney inspections
- Pool and spa evaluations
- Well and septic system testing
- Underground storage tank assessments
If your inspector sees anything concerning in any of these areas, they’ll recommend the appropriate specialist for follow-up. Ask your real estate agent ahead of time which add-ons are worth considering for the specific home and neighborhood. In some areas or with older homes, a sewer scope or radon test can be well worth the extra cost.
Why the Home Inspection Matters for Buyers
A home inspection gives you two things: information and leverage. If the inspector finds significant issues — a failing roof, an aging HVAC system, or faulty wiring — you have options. You can negotiate with the seller for repairs or a price reduction, request credits at closing, or, in some cases, walk away from the deal entirely while keeping your earnest money.
Even a clean inspection is valuable. It confirms the home is in the condition you believed it to be, and it gives you a detailed maintenance roadmap for the years ahead — a picture of what systems are aging and what you should plan to budget for down the road.
A Note for Buyers in St. George, Utah
Southern Utah’s desert climate creates some specific inspection considerations that buyers should be aware of. Intense UV exposure and dramatic temperature swings can accelerate wear on roofing materials and exterior caulking. Air conditioning systems work much harder here than in milder climates — a thorough HVAC evaluation is especially critical. Stucco exteriors common in the region should be closely checked for cracking that allows moisture intrusion. And while the area is generally dry, flash flooding events mean grading and drainage around the foundation deserve careful attention. Working with a local inspector who understands St. George’s unique conditions is a real advantage.
Frequently Asked Questions
How long does a home inspection take?
Most inspections take 2–4 hours depending on the size and age of the home. Larger or older homes may take longer. Plan to attend the full inspection if you can — it’s the best chance to ask questions and understand findings in real time.
Should I be present during the inspection?
Yes — attending is strongly recommended. Walking through the home with the inspector lets you see issues firsthand, ask questions in the moment, and leave with a much clearer understanding of the property than any written report can convey on its own.
What if the inspection reveals major issues?
That’s exactly what the inspection is for. Your real estate agent can help you navigate next steps — whether that’s negotiating repairs, requesting a credit at closing, asking for a price reduction, or in serious cases, exercising your inspection contingency to exit the contract.
Who pays for the home inspection?
In most transactions, the buyer pays for the inspection. Costs typically range from $300–$500, though this varies by location and home size. It’s one of the best investments you’ll make in the home-buying process.
Can a home fail a home inspection?
Not technically — inspections don’t pass or fail. They produce a report documenting the home’s condition. What you do with that information is up to you and your agent. Even a report with a long list of issues isn’t necessarily a dealbreaker; it’s information that helps you negotiate.
