Home Inspection Red Flags for Calgary Buyers

By Evans Dobey, REALTOR® | What a Calgary home inspection covers, and how the risks change with the age of the home

Why the inspection matters

In most Calgary purchase contracts, the home inspection is your last chance to walk away or renegotiate before your conditions come off. So it’s worth knowing what to look for.

It matters more here than in many cities because Calgary’s homes vary so much. Pre-war character homes sit a few kilometres from subdivisions that are still being built, and each era has its own typical problems. A 25-year-old roof, a certain electrical panel or a crack in the foundation means something different depending on when the house was built. Once you know what’s normal for a home that age, you can tell which findings to worry about.

This page is only about the inspection: what the inspector checks, which findings are worth stopping on, and how that changes from older communities to newer ones. For the whole buying process, see my guide to buying a home in Calgary.

What a home inspector checks

A standard inspection is a visual check. The inspector doesn’t open up walls. It usually takes two to three hours and covers these systems:

Foundation and structure: visible cracking, settling, and any evidence of past water intrusion.
Roof and exterior envelope: shingle condition, flashing, siding, and grading against the foundation.
Electrical: panel type and age, wiring type throughout the home, and whether past work was permitted.
Plumbing: supply lines, drain lines, water heater age and condition, and visible leaks.
Heating and cooling: furnace age and condition, venting, and any safety concerns.
Insulation and ventilation: attic and basement insulation levels, and signs of past moisture.

Findings worth stopping on

Most of what an inspector finds is minor and normal for the age of the home. A good report is usually a long list of small maintenance items. These are the findings that can mean big repair bills or safety problems, and they’re worth a closer look before you remove conditions.

Active water intrusion or efflorescence: a damp basement or white mineral staining on foundation walls usually means water is finding its way in, not just condensation. Get a clear explanation before you waive conditions.
Non-hairline foundation cracks: cracks wider than a coin, horizontal cracks, or cracks paired with sticking doors and uneven floors can point to ongoing settlement rather than normal curing.
Double-tapped breakers or unpermitted electrical work: two wires under one breaker terminal, or a panel that does not match city permit records, is both a safety flag and an insurance flag.
A roof near or past end of life: most Calgary asphalt shingles are rated 20 to 25 years. A roof at that age with visible granule loss is a near-term expense to negotiate on now, not just note for later. See my hail and home insurance guide for how roof age affects your coverage.
Original clay or unidentified sewer lateral material: older clay pipe is prone to root intrusion and cracking. A camera scope inspection is inexpensive compared with a collapsed line the month after possession.

Older homes: what to look for

Communities like Inglewood and Mount Royal have some of Calgary’s best character homes, built from the 1910s to the 1950s. They come with their own list of things to check.

Wiring. Original knob-and-tube or early aluminum wiring is common, and insurers often want it replaced or certified by an electrician before they’ll cover the home.
Sewer lines. Original clay sewer lines are now 70 to 100-plus years old and a common cause of surprise plumbing bills. Get a camera scope before you close.
Foundations. Settling shows up more often on older lots.
Asbestos. It can still turn up in vermiculite attic insulation, old floor tiles or pipe wrap.

None of this has to rule out a great character home. Get a specialist’s opinion and a price for each item before you remove conditions.

Newer homes: what to look for

Buyers in newer communities like Auburn Bay, Mahogany and Tuscany sometimes skip the inspection or don’t take it seriously. Newer homes have different problems, not fewer.

Builder-grade finishes. Fixtures and finishes are chosen to hit a price, and some won’t last as long as you’d expect.
Grading and drainage. Landscaping is often rushed at the end of construction, or added later by an owner without proper grading, so water can drain toward the house.
Basements finished without a permit. This is one of the most common findings. It can mean unapproved egress windows, undersized framing or wiring no city inspector has seen, and it becomes your problem the day you take possession.

Common questions

Have a question that isn’t here? Check the real estate glossary or ask me and I’ll get back to you, usually the same day.

Should I still get an inspection on a brand-new build?

Yes. An inspection on a new build catches grading problems, items the builder hasn’t finished from their own deficiency list, and poor workmanship before your warranty clock starts. It doesn’t cost much compared to what it can catch.

What if the inspection finds a problem, can I renegotiate?

In most cases, yes, as long as your offer had a home inspection condition. You can ask the seller to fix the problem, ask for a credit at closing, or sometimes walk away from the deal completely. It depends on exactly how the condition was written.

How much does a home inspection cost in Calgary?

Most standard inspections cost about $400 to $700, more for a bigger home or extras like a sewer scope. It’s one of the smaller costs of buying, and one of the most useful.

Do I need a separate sewer scope inspection?

It isn’t part of a standard inspection, but I recommend one on any home with original clay sewer lines or where nobody knows what the line is made of, especially in Calgary’s older communities. A scope doesn’t cost much compared to a collapsed sewer line after you own the home.
