How much is a home inspection cost is the first question many buyers ask once they have an accepted offer and a contingency period ticking down. The short answer is that most general home inspections fall between three hundred and five hundred dollars, with smaller and newer homes at the low end and larger or older homes at the high end. The longer answer involves square footage, age, foundation type, regional pricing, and the add-on tests buyers commonly bundle — radon, mold, sewer scope, termite, and water quality each carry their own price. This guide walks through each pricing driver, the per-square-foot logic inspectors use, the regional spread, and what the final invoice typically looks like for a Front Range buyer in 2026.

How much is a home inspection cost — the headline range

National general home inspection pricing in 2026 sits roughly between three hundred and five hundred dollars for a single-family home under three thousand square feet. The American Society of Home Inspectors and InterNACHI both publish member rate surveys that place the median nationally near four hundred dollars. Front Range Colorado homes typically run four hundred to five hundred fifty dollars for the standard scope. The figure is a starting point — add-ons push the total up, and complex or large homes push the standard scope up before add-ons enter the picture.

Per-square-foot pricing logic

Most inspectors price using a base fee for a standard-size home plus a per-square-foot adder for anything above that baseline. A common structure: four hundred dollars for the first two thousand square feet, then fifteen to twenty-five cents per square foot above that. So a three-thousand-square-foot home runs four hundred plus roughly two hundred for the extra thousand feet — six hundred total. A five-thousand-square-foot home runs four hundred plus six hundred — one thousand dollars. The exact rate varies by market, but the linear structure holds across most independent inspectors and franchise operators.

Why home age matters

Older homes take longer to inspect because there are more systems to evaluate (galvanized plumbing, knob-and-tube electrical, asbestos-era insulation, original boilers) and more failure points to document. Inspectors typically add fifty to one hundred fifty dollars for homes over fifty years old. Homes built before 1978 also commonly trigger lead and asbestos disclosure considerations, which the inspector flags but does not test for unless contracted separately. The age premium reflects time on site, not just risk.

Foundation type and crawl-space access

Slab-on-grade homes inspect fastest. Basements add complexity for foundation walls, sump systems, and any finished-versus-unfinished status. Crawl spaces add the most time because the inspector physically enters the space, photographs the perimeter, and documents anything from moisture intrusion to rodent activity. Some inspectors charge a flat add-on for crawl-space entry — typically twenty-five to seventy-five dollars. Sellers who decline crawl-space access usually trigger a disclaimer on the report rather than a discount.

Add-on tests buyers bundle most often

Radon testing runs one hundred fifty to two hundred dollars typically — the inspector deploys a continuous radon monitor for forty-eight hours and returns to retrieve it. Mold inspection with air sampling runs four hundred to one thousand five hundred dollars depending on the number of samples sent to a lab. Sewer scope (camera inspection of the main sewer line from cleanout to street) runs one hundred to three hundred dollars. Termite or WDO inspection runs fifty to one hundred fifty dollars. Water quality testing runs one hundred fifty to four hundred dollars. The Colorado home inspection cost reference breaks down which add-ons are common in Front Range transactions.

What is not included in the general inspection

The standard scope covers the visible and accessible portions of the structural, electrical, plumbing, HVAC, roofing, and major systems. It does not include destructive testing, climbing into inaccessible attics, opening sealed walls, testing for any specific contaminant, evaluating pools or spas as standard, or testing private well or septic systems. Buyers expecting those tasks should add them as contracted scope items before the inspection.

Regional pricing variation

Coastal and high-cost-of-living markets typically charge more. San Francisco Bay Area and Seattle inspections often start at six hundred dollars. Midwest and Plains states run lower, with the median nearer to three hundred fifty dollars. Texas inspections vary by metro — Dallas-Fort Worth tends to be higher than Houston. Mountain West (Denver, Salt Lake City, Boise) runs near the national median. The variation reflects inspector demand, cost of insurance, and local market rates, not differences in scope.

Per-square-foot tiers in practice

A 1,500-square-foot single-story typically inspects in two and a half hours and bills three hundred fifty to four hundred dollars. A 2,500-square-foot two-story typically takes three to four hours and bills four hundred fifty to five hundred fifty. A 4,000-square-foot home commonly takes five to six hours and bills seven hundred to nine hundred. Luxury homes above six thousand square feet often bill one thousand to one thousand five hundred for the base scope before add-ons. These ranges are pulled from ASHI and InterNACHI member survey data and consumer reporting on the home inspection industry.

How buyers compare three quotes apples to apples

Quotes that differ by more than thirty percent are usually scoping different work. Ask each inspector to itemize: standard scope, square-footage adder, age adder, crawl-space adder, add-on tests, sample-report fee, and report delivery time. Confirm in writing that the inspector carries general liability and errors-and-omissions insurance — both are standard for ASHI and InterNACHI members. Confirm that the inspector follows a published Standard of Practice (typically ASHI SOP or InterNACHI SOP). Cheapest is rarely best in this transaction because a missed defect can cost ten to fifty times the inspection fee at closing.

When the inspector quotes a flat fee

Some inspectors quote one flat fee regardless of home size up to a defined ceiling (often three thousand square feet). The flat-fee model is simpler for buyers but typically prices above the per-square-foot average for small homes and below it for large homes. Both pricing models are legitimate. The buyer should ask explicitly which model the inspector uses and where the home falls on the curve.

Discounts and bundle pricing

Inspectors commonly discount add-ons that are bundled with the general inspection — radon plus general often runs five hundred fifty rather than five hundred fifty plus one seventy-five as separate visits. Re-inspection fees (the inspector returns after seller repairs to verify completion) typically run one hundred to two hundred dollars or a percentage of the original fee. Some inspectors waive re-inspection fees if the original work was bundled with multiple add-ons.

Cash, credit card, and invoicing

Most independent inspectors accept credit card payments and provide an invoice that can be submitted to a lender if the inspection cost is being financed into closing. A few smaller operators still prefer cash or check. Franchise operators always accept cards. Ask about payment timing — most inspectors collect at the time of the inspection or before the report is released, not at closing.

Special add-on — pool, spa, and outbuilding inspection

Standard scope does not include pools, spas, or detached structures over a defined size. Pool and spa inspection commonly adds one hundred fifty to three hundred dollars. Detached garage or workshop inspection adds fifty to one hundred fifty depending on size. Sheds and very small outbuildings are typically inspected free as part of the general scope. Confirm scope with the inspector before the visit if the property has multiple structures. See the hiring a home inspector pillar guide for the full scope reference.

Sample reports and delivery time

Most inspectors deliver the written report within twenty-four hours of the inspection. Some send a same-day summary with the full report following within forty-eight hours. The report length runs thirty to one hundred pages depending on home age and number of findings. Sample reports should be available on the inspector’s website — review one before booking to confirm the format matches what the buyer’s agent and attorney expect.

What a buyer should ask before booking

Ask about base fee, square-footage and age adders, add-on prices, insurance coverage, certifications (ASHI or InterNACHI), Standard of Practice followed, sample report availability, report delivery time, re-inspection policy, and whether the inspector permits the buyer to attend. Attending is strongly recommended — the inspector can walk the buyer through findings live, which often reveals context that the written report cannot.

Booking lead time and the rush premium

Standard-week booking two to seven days in advance secures the standard per-square-foot rate. Same-day or next-day urgent inspections typically run twenty-five to fifty percent above standard. Weekend inspections sometimes carry a fifty-dollar surcharge. Buyers in tight contingency-period transactions should call the inspector immediately upon offer acceptance to lock in the standard rate. The premium structure is consistent across most metro markets.

Re-inspection fees after seller repairs

If the original inspection identifies repairs and the seller agrees to address them, a re-inspection visit verifies the work was completed properly. Re-inspection fees typically run one hundred to two hundred dollars or twenty-five to fifty percent of the original fee. Some inspectors waive the charge for clients who used a comprehensive package or who complete the re-inspection within thirty days. Confirm the re-inspection policy at initial booking rather than after the seller-repair phase begins.

When to call a specialist instead

If the property has known issues — visible foundation cracks, recurring moisture damage, suspected illegal additions, or specific system failures — a specialist inspection often adds more value than a general one. Foundation engineers, licensed roofers, and HVAC contractors charge similar rates and produce deeper technical detail in their domain. Buyers can combine a general inspection with one specialist inspection for under a thousand dollars total in most markets, which is typically a better investment than adding multiple generalist visits.
