A general home inspection is the comprehensive visual evaluation a buyer commissions during the option period of a real-estate transaction. It covers roughly ten distinct building systems, follows the ASHI or InterNACHI Standards of Practice, and produces a written report identifying material defects, safety concerns, and items requiring further professional evaluation. This 2026 buyer-facing flagship guide walks through what the inspection actually covers, what it does not, what Front Range pricing looks like, and how the general inspection differs from the lender appraisal that often runs the same week.

What a general home inspection covers

A standards-compliant general home inspection covers ten categories. The roof — covering material, flashings, gutters, drainage, visible attic-side framing. The exterior — siding, trim, decks, porches, walkways, grading, exterior drainage. The structure — visible foundation, framing, crawl space, basement walls. The plumbing — supply lines, drain-waste-vent system, fixtures, water heaters. The electrical — service entrance, panel, branch circuits, outlets, GFCI/AFCI protection.

The HVAC — heating equipment, air conditioning, ductwork, ventilation. The interior — walls, ceilings, floors, doors, windows, stairs. The attic — insulation, ventilation, visible framing. The basement — moisture, structure, mechanical equipment. The appliances — typically built-in kitchen appliances tested in normal operating mode. Each category gets a defined assessment per the Standards of Practice, with defects categorized as material, safety, or further-evaluation findings.

How long the inspection takes

A general home inspection on a 1,800 to 2,500-square-foot single-family home typically runs two and a half to four hours on site. Smaller homes finish in two hours; larger homes with multiple HVAC systems, finished basements, and complex roof geometry can run five hours or more. Buyers should plan to be on site for at least the last 30 to 60 minutes to walk through findings with the inspector.

Report turnaround typically runs 24 to 48 hours after the on-site inspection. Most inspectors produce digital PDF reports with annotated photos, often delivered through report-software platforms that organize findings by category and severity. The combination of on-site time plus report writing is what justifies the $400 to $550 Front Range price point.

The ten inspection categories in detail

Each of the ten categories carries specific evaluation requirements. The roof category includes covering material identification (asphalt, tile, metal, membrane), flashing condition around penetrations, gutter and downspout function, and visible attic-side framing for moisture or pest damage. Inspectors evaluate from a ladder when safely accessible, from the roof surface for low-slope roofs, or via drone imagery for steep or icy roofs.

The exterior category covers siding material and condition, trim and fascia, decks and porches with attention to attachment hardware, walkways, exterior grading and drainage away from the foundation, and exterior penetrations including dryer vents and HVAC equipment housings. The structure category evaluates visible foundation walls, basement floor cracks, crawl space conditions including vapor barrier presence, and accessible framing components.

The plumbing category tests supply line pressure at multiple fixtures, drain operation, fixture function, water heater age and condition, and visible main sewer line cleanouts. The electrical category evaluates the service entrance, main panel and subpanels for double-tapped breakers and proper grounding, branch circuits, outlets via GFCI testing, AFCI protection where applicable, and visible wiring methods. The HVAC category tests heating and cooling equipment in normal operating mode, evaluates ductwork for visible damage, and checks filter condition and equipment age.

The ASHI and InterNACHI Standards of Practice framework

The Standards of Practice (SoP) documents from ASHI and InterNACHI define the minimum scope of a compliant general home inspection. Both SoPs are nearly identical in coverage and structure. They specify which systems must be inspected, which components must be evaluated within each system, and which exclusions are explicitly outside scope.

The SoP framework provides predictability — buyers know what they are buying, inspectors know what they are obligated to evaluate, and disputes can reference a published standard rather than vague expectations. An inspector advertising “ASHI ACI” or “InterNACHI CPI” credentials is committing to the relevant SoP. Buyers should expect the inspection report to reference SoP categories directly. For methodology context, see what is involved in a home inspection process guide.

What a general home inspection does not cover

The SoP frameworks explicitly exclude several categories. Mold, radon, asbestos, lead, and other environmental hazards are not part of a general inspection — buyers concerned about those need separate specialty testing. Sewer scope inspections (camera inspection of the main sewer line) are not included. Wood-destroying insect inspections (termite and carpenter ant) are typically separate. Pool and spa equipment beyond surface observation often falls outside scope.

Cosmetic items, code compliance for current versus historical codes, and predictions of future failures sit outside scope as well. The inspection reports the visible current condition — it does not predict when a 14-year-old furnace will fail or whether 1992 wiring meets 2026 code. For a parallel scope-focused piece, see what does a home inspector look for.

How inspectors categorize findings in reports

Most inspection reports organize findings using a three-tier severity system. Safety findings represent immediate hazards — exposed wiring, malfunctioning carbon monoxide detectors, GFCI protection failures in wet areas. Material findings represent significant defects affecting the home’s habitability or repair cost — failed water heaters, active roof leaks, foundation cracks beyond hairline. Monitor findings represent items in degraded but not failed condition — aging HVAC equipment near end of life, minor drainage concerns, surface-level cosmetic issues that may indicate underlying problems.

Each finding typically includes a description, an annotated photo with arrows or circles highlighting the specific concern, a recommendation specifying immediate repair, professional further evaluation, or monitor over time, and a category-system tag indicating which SoP category the finding falls under. Report length varies — a clean home on a small property may produce a 25-page report, while an older home with multiple system issues may produce 80+ pages.

Buyers should look for specific recommendations rather than vague boilerplate. A finding noting “evidence of past leak at chimney flashing — recommend evaluation by qualified roofer” produces actionable next steps. A finding noting “concerns noted — consult specialist” provides little useful information for negotiation or remediation planning.

Front Range pricing in 2026

A general home inspection on a 1,800 to 2,500-square-foot single-family home runs $400 to $550 across the Denver metro and Front Range corridor in 2026. Boulder county trends slightly higher. Smaller properties under 1,500 square feet run $325 to $400. Larger homes above 3,500 square feet run $550 to $750. Multi-family properties, properties with detached structures, and homes with crawl-space-only access can add $100 to $250.

Add-on services common on the Front Range include sewer-scope inspections ($175 to $275), radon testing ($150 to $200), thermal-imaging scans ($150 to $300), and wood-destroying insect inspections ($75 to $150). Many inspectors offer bundles that reduce total cost by 10 to 15 percent compared to ordering services separately. For a deeper pricing breakdown, see how much home inspection 2026 cost guide.

How the general inspection differs from the lender appraisal

Buyers sometimes assume the appraisal substitutes for the inspection. It does not. The lender appraisal serves the lender’s interest — confirming the property’s market value supports the mortgage amount. Appraisers spend 20 to 45 minutes on site, document basic condition for valuation purposes, and produce a value-focused report.

The general home inspection serves the buyer’s interest — identifying defects and conditions affecting the home’s habitability, safety, and likely repair cost. Inspectors spend two to five hours on site, evaluate ten building-system categories per the SoP, and produce a buyer-focused report. The two reports answer different questions and rarely substitute for each other. Buyers commission both during a typical Front Range transaction.

What buyers do with inspection findings

Inspection findings drive three typical buyer responses during the option period. First, request seller repairs for material defects — failed water heaters, roof leaks, electrical hazards. Second, request a price reduction or seller credit reflecting estimated repair costs the buyer will assume. Third, walk away from the transaction if findings reveal undisclosed problems beyond the buyer’s tolerance.

Inspectors do not typically estimate repair costs in their reports — that work falls to specialty contractors the buyer hires for quotes during the option period. Inspectors do, however, often categorize findings by severity (safety, material, monitor) and by recommendation (immediate repair, professional further evaluation, monitor over time), which helps buyers triage during the negotiation window.

How long the option period gives buyers to act

Front Range purchase contracts typically include an inspection objection deadline 5 to 14 calendar days from contract execution, with most landing at 7 to 10 days. The general home inspection itself happens early in that window — usually within the first 3 to 5 days — to leave time for specialty add-on inspections and contractor quotes for repair estimates before the objection deadline arrives.

Buyers using the option period strategically schedule the general inspection within 48 hours of contract execution, allow 24 to 48 hours for the report, then schedule add-on services and contractor walkthroughs for the next 3 to 5 days. The compressed timeline rewards inspectors who deliver reports within 24 hours and who maintain relationships with specialty inspectors who can schedule quickly.

The objection deadline matters because once it passes, the buyer loses negotiating leverage for any issue discovered later. Findings discovered after the deadline still belong to the buyer to address, but seller credit or repair negotiations typically end at the objection deadline. Buyers should treat the deadline as firm and plan inspections to complete with margin for follow-up.

How to choose a general home inspector

Three quick checks separate qualified inspectors from marginal ones. Confirm ASHI ACI or InterNACHI CPI credential status via the public directories on homeinspector.org or nachi.org. Request a sample report from a recent inspection — format, photo quality, finding clarity, and writing quality reveal a lot about an inspector’s standards. Ask for proof of E&O insurance coverage.

A fourth check matters too. Ask whether the inspector lets buyers attend the inspection and walks through findings at the end. Walk-throughs add diagnostic value buyers cannot get from a written report alone, and any inspector reluctant to host that walk-through is signaling something about their process.

When buyers need add-on inspections beyond the general scope

Three add-ons make sense on most Front Range transactions. Sewer-scope inspections catch buried main-line failures that surface plumbing inspection cannot reveal — particularly important for homes 30+ years old. Radon testing applies broadly across Colorado where roughly half of homes test above the EPA action level. Thermal-imaging scans catch HVAC and insulation issues invisible to visual inspection.

For homes with specific concerns, mold testing, asbestos and lead surveys for pre-1978 construction, and wood-destroying insect inspections may also warrant the additional fees. The broader hiring a home inspector pillar guide covers how the general inspection fits a complete pre-purchase due diligence workflow.

Buyers should treat the general inspection as the foundation of due diligence rather than the entirety of it. The general scope is comprehensive within its defined categories but explicitly excludes environmental hazards, specialty systems, and predictive failure analysis. Add-on inspections fill those gaps and produce a complete picture of the property’s condition before the option-period objection deadline closes.
