How Much Is It for a Home Inspection: By Property Type
How much is it for a home inspection comes down to the property type as much as the home’s size or age. A single-family detached home, a condo, a townhouse, a duplex, a luxury custom home, and a new-construction phased inspection each carry different price ranges because the scope and time differ. This guide walks through the 2026 price range by property type, the add-on tests buyers typically bundle, and realistic total examples drawn from common transaction scenarios. The pricing reflects ASHI and InterNACHI member rate survey data and consumer reporting on inspection fees in mid-cost U.S. markets.
How much is it for a home inspection — the price range by property type
Single-family detached homes run three hundred fifty to seven hundred dollars depending on size. Condominiums run three hundred to four hundred. Townhouses run three hundred fifty to five hundred. Duplexes run five hundred fifty to seven hundred fifty. Triplexes and small multi-family run seven hundred to twelve hundred. Luxury custom homes run one thousand to two thousand five hundred. New construction phased inspections run two hundred to three hundred per phase. Add-ons (radon, mold, sewer scope, WDO, water) add one hundred to fifteen hundred depending on the test mix.
Single-family detached — the most common scenario
A 1,500-square-foot single-family detached typically inspects at three hundred fifty to four hundred dollars. A 2,500-square-foot two-story typically runs four hundred fifty to five hundred. A 3,500-square-foot home typically runs six hundred to seven hundred. A 4,500-square-foot home typically runs seven hundred fifty to nine hundred. The base fee plus per-square-foot adder structure explains the linear scaling. Front Range Colorado homes typically run modestly above the national median for equivalent size. The Colorado home inspection cost guide covers the regional context.
Condominium — the small-scope segment
Condominium inspections run three hundred to four hundred dollars because the unit-owner’s responsibility is limited. The inspector evaluates the interior of the unit, in-unit systems, appliances, and any exclusively-owned exterior elements. Common elements (roof, foundation, exterior walls, hallways, parking) are HOA responsibility and not in the unit inspection’s scope. Condo buyers should also request the HOA’s reserve study and recent meeting minutes — those represent property risks the inspector cannot evaluate.
Townhouse — between condo and single-family
Townhouse inspections run three hundred fifty to five hundred dollars. The unit is typically a multi-story attached dwelling with the owner responsible for the interior, in-unit systems, and often the unit’s own roof and a small private yard or patio. Shared exterior walls and common elements remain HOA responsibility. The inspector should clarify which exterior elements are unit-owner versus HOA before the visit to match scope to actual ownership boundaries.
Duplex and small multi-family inspections
Duplex inspections run five hundred fifty to seven hundred fifty dollars because the inspector evaluates two distinct unit interiors plus shared mechanical and structural systems. Triplex and four-unit buildings run seven hundred to twelve hundred. Larger multi-family above five units typically moves into commercial inspection territory. Investor buyers should confirm whether the inspector evaluates each unit fully or only a representative sample plus the shared systems.
Luxury and custom home inspections
Luxury homes over five thousand square feet run one thousand to two thousand dollars for the general inspection. Custom homes with complex mechanical systems (geothermal HVAC, integrated home automation, indoor pools, elevators, dedicated wine cellars) push two thousand to two thousand five hundred. Premium-tier inspectors for this segment hold additional credentials and spend six to ten hours on site. The premium reflects time and expertise, not just branding.
New construction phased inspections
New construction inspections at foundation, framing, pre-drywall, and final stages each run two hundred to three hundred fifty dollars. The combined cost across all four phases runs eight hundred to fourteen hundred dollars. Each phase evaluates work that gets covered up by subsequent construction — foundation before backfill, framing before insulation, pre-drywall before sheetrock — making phased inspection materially more useful than a single final visit. Many builders resist inspection access; write the rights into the construction contract explicitly.
Manufactured and modular home inspections
Manufactured home inspections run three hundred to four hundred dollars depending on setup, year, and modifications. Modular and prefab homes installed on permanent foundations inspect like equivalent-size site-built homes at single-family detached pricing. The inspector documents the connection between modules, the foundation, the roof and wall seams, and any post-installation modifications.
Add-on radon testing
Radon testing runs one hundred fifty to two hundred fifty dollars and uses a continuous radon monitor for forty-eight hours. EPA recommends radon testing during every home purchase regardless of regional zone. Buyers in Zone 1 (much of the Mountain West, Northeast, and Midwest) should treat the test as effectively mandatory. The Front Range falls in Zone 1. The radon testing pillar guide covers the regional context.
Add-on mold inspection
Mold inspection with air sampling runs four hundred to fifteen hundred dollars depending on sample count and lab fees. The variation reflects sample volume, not inspector quality. Mold inspection is worth the cost when there are visible water-damage marks, persistent musty odors, or specific health concerns. Routine mold testing on a dry home without visible signs is generally unnecessary.
Add-on sewer scope
Sewer scope runs one hundred to three hundred dollars and is one of the highest-value add-ons for homes over twenty years old. The camera inspection identifies root intrusion, pipe damage, bellies, and material composition. Main-line replacement runs five to fifteen thousand dollars and almost never appears on the general inspection report. The asymmetry between add-on cost and potential discovery makes sewer scope a near-mandatory inclusion on older-home purchases.
Add-on WDO and water testing
WDO (Wood-Destroying Organism) inspection runs fifty to one hundred fifty dollars and is required by some loan programs. Water quality testing runs one hundred fifty to four hundred depending on the panel (basic versus comprehensive). Public water rarely requires testing because the utility tests at source. Private well water benefits significantly from comprehensive testing.
Putting together a typical total — three scenarios
Scenario one: 2,000-square-foot single-family detached, 1990 build, Front Range. Base inspection four hundred fifty, radon one hundred seventy-five, sewer scope one hundred seventy-five. Total eight hundred dollars. Scenario two: 1,200-square-foot condo, 2010 build, mid-cost metro. Base inspection three hundred fifty. Total three hundred fifty. Scenario three: 4,500-square-foot luxury custom, 2005 build, Front Range. Base inspection nine hundred, radon two hundred, sewer scope two hundred, mold inspection six hundred. Total one thousand nine hundred dollars.
Travel surcharges and rush booking
Inspectors based outside the property’s metro may add fifty to one hundred dollars as a travel fee. Same-day or next-day urgent inspections often run twenty-five to fifty percent above standard. Weekend inspections sometimes carry a fifty-dollar surcharge. Buyers in tight contingency-period transactions should book the inspector at the same time as the offer to avoid rush pricing.
Re-inspection after seller repairs
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 completed a comprehensive package or who finish the original inspection within thirty days. Confirm re-inspection policy before booking.
How to compare three quotes
Pull three itemized quotes from local inspectors with active ASHI or InterNACHI certification and full insurance documentation. Confirm each quote breaks out the property-specific base fee, adders, and add-ons consistently. Quotes that vary by more than thirty percent within the same property type are usually scoping different work. Choose the inspector with the most detailed quote at a price near the local median for that property type. The hiring a home inspector pillar guide covers the comparison framework.
Franchise versus independent across property types
Franchise operators (HomeTeam, Pillar To Post, AmeriSpec, Win Home Inspection) typically match or slightly exceed the local independent median across most property types. The franchise premium covers brand training and consistent reporting. For unusual property types — historic, luxury custom, complex commercial multi-family — independent inspectors with relevant specialty experience often outperform franchises on both price and depth. For standard single-family detached, condo, and townhouse, both models work well.
Booking timing and the lead-time premium
Standard-week booking two to seven days in advance secures the standard property-type rate. Same-day or next-day urgent inspections run twenty-five to fifty percent above standard. Weekend inspections sometimes carry a fifty-dollar surcharge. Buyers in tight contingency-period transactions should book immediately upon offer acceptance. The lead-time premium structure is consistent across all property types.
Pre-listing inspection — the seller’s variant
Some sellers commission a pre-listing inspection to surface issues before listing. The pre-listing inspection follows the same property-type scope and pricing as a buyer’s inspection but is paid for by the seller. Buyers who receive a recent pre-listing report should still book their own inspection — the findings may be reliable, but the inspector worked for the seller and the buyer benefits from an independent advocate working under the buyer’s contingency rights.
When to add a specialist inspection
For homes with known foundation issues, suspected moisture damage, complex mechanical systems, or recent additions of questionable quality, add a targeted specialist visit alongside the general inspection. Foundation engineers, licensed roofers, HVAC contractors, and structural engineers charge similar rates and produce deeper technical detail in their domain. Combining one general inspection with one specialist visit typically stays under two thousand dollars in most markets and produces meaningfully better intelligence than two general inspections at any property-type price point.
