"How long will the inspection take?" is one of the first questions every Calgary buyer asks — and the honest answer is that it depends on the property. A 900 sq ft condo can be done in about 90 minutes, while a 4,000 sq ft acreage with a well, septic, and two outbuildings can eat up half a day. Here's a detailed breakdown of how long a home inspection takes by property type, size, age, and the variables that add time on site.

Quick answer: how long is a typical Calgary home inspection?

For a standard detached Calgary home between 1,500 and 2,500 sq ft, expect the inspection to take 2.5 to 3.5 hours on site. That includes the full walk-through, thermal imaging, drone roof scan, and time to document findings. Add-ons like a sewer scope or radon test add 30–60 minutes each. The written digital report is then delivered the same day, usually within a few hours of leaving the property.

Home inspection time by property type

Condo / apartment: 1.5 – 2 hours (no roof or exterior envelope to inspect)
Townhouse: 2 – 2.5 hours
Detached home under 2,000 sq ft: 2 – 2.5 hours
Detached home 2,000 – 3,000 sq ft: 2.5 – 3.5 hours
Detached home 3,000 – 4,500 sq ft: 3.5 – 4.5 hours
Estate / acreage (4,500+ sq ft): 4.5 – 6+ hours
Mobile / manufactured home: 1.5 – 2.5 hours
Pre-drywall / new construction: 2 – 3 hours
11th-month warranty inspection: 2.5 – 3.5 hours
Pre-listing (seller) inspection: same as the matching buyer inspection

These are on-site times only. Add another 1–2 hours off-site for the inspector to finalize the written report with photos and thermal images.

What actually happens during those hours

A thorough inspection isn't a quick walk-through — it's a systematic evaluation of every major system. Here's roughly how the time breaks down for a standard 2,200 sq ft detached home:

Exterior & roof (45–60 min): Drone roof scan, flashings, chimney, eavestroughs, siding, grading, deck, garage.
Interior structure & envelope (30–45 min): Foundation walls, windows, doors, visible framing, moisture metering.
Electrical (30 min): Panel, wiring type, GFCI/AFCI testing, representative outlets throughout.
Plumbing (30 min): Supply lines, drain type (Poly-B, cast iron, ABS), water heater, shut-offs, fixtures.
HVAC (20–30 min): Furnace, AC, humidifier, ductwork, filters, venting.
Attic & insulation (20–30 min): Vapour barrier, ventilation, depth and type of insulation, signs of leaks.
Appliances & built-ins (15–20 min): Functional test of stove, dishwasher, garbage disposal, etc.
Thermal imaging scan (15–30 min): Every exterior wall, ceiling, and around windows/plumbing for moisture and insulation gaps.
Documentation & wrap-up (15–20 min): Photo organization, summary notes, final walkthrough with the client.

Variables that add (or subtract) time

1. Square footage

This is the biggest single driver. Every additional 1,000 sq ft adds roughly 45–60 minutes because there are more rooms, more outlets, more fixtures, and more exterior wall to scan thermally.

2. Age of the home

A 2022 build in Mahogany goes faster than a 1912 Inglewood character home. Older Calgary homes require closer scrutiny of knob-and-tube or aluminum wiring, Poly-B or cast iron plumbing, foundation type, and legacy heating systems. Budget an extra 30–60 minutes for anything built before 1960.

3. Property type and complexity

Condos skip the roof, exterior envelope, and often the attic — that's why they're the fastest. Acreages add wells, septic fields, cisterns, outbuildings, and propane systems. Homes with legal or illegal suites essentially double the plumbing and electrical documentation. Anything with a detached garage, shop, or secondary structure adds 15–45 minutes each.

4. Add-on services

Sewer scope: +30–45 minutes (setup, camera run, cleanup)
Radon short-term test: +15 minutes to place the monitor (pick-up happens days later)
WETT / wood stove inspection: +20–30 minutes
Pool / hot tub: +30–45 minutes
Mold or air quality sampling: +20–30 minutes

5. Condition and accessibility

A home with a finished basement, covered attic hatch, or storage-packed garage slows the inspector down because access has to be cleared. Snow cover hides grading, decks, and AC units — winter inspections often require a return visit or a documented limitation. Conversely, a vacant, empty home with clear access moves quickly.

6. Whether the client attends

You're welcome to follow along — and most buyers do for at least part of it. A client asking thoughtful questions doesn't slow a good inspector much, but a full walk-through with multiple decision-makers can add 30+ minutes. Some inspectors prefer to inspect first and walk the client through findings at the end; either approach is fine.

How long should you block off your calendar?

As a buyer, plan to be on site for 2.5 to 4 hours for a typical detached home. You don't have to stay the entire time, but being there for the final walkthrough is where you'll learn the most. Bring questions, a notepad, and comfortable shoes — you may be climbing into the attic or around the exterior.

For sellers doing a pre-listing inspection, you can usually leave the inspector to work and receive the report digitally the same day.

Why a faster inspection isn't a better inspection

A 90-minute inspection on a 2,400 sq ft detached home is a red flag. To finish that fast, something is being skipped — usually the attic, the thermal scan, or a meaningful portion of the electrical and plumbing. The math is simple: a home has hundreds of outlets, dozens of fixtures, multiple roof planes, and every exterior wall worth imaging. Rushing means missing things. The cheapest inspection is usually the most expensive for the same reason.

How long until you get the report?

At HomeWise, the interactive digital report is delivered the same day — typically within a few hours of the inspection, and always within 24. The report includes annotated photos, thermal images, severity ratings, and a clear summary of what to fix, monitor, or negotiate. You can read a sample report to see exactly what lands in your inbox.
