The short answer
Yes. A new house is built by people, in weather, on a schedule, by trades who are working several houses at once. New does not mean flawless, and warranty coverage is a mechanism for getting things fixed — not a reason to skip looking.
The useful distinction is this: the builder's walkthrough is the builder's process, on the builder's form, with the builder's definition of what counts as a deficiency. An inspector you hire works for you. Both have a place. Only one of them is on your side of the table.
Three moments worth an inspection, not one
- Pre-drywall. This is the one most buyers miss and the one that matters most. Once the boarding goes up, framing, strapping, plumbing runs, electrical, ducting, insulation and vapour barrier all disappear for the life of the house. An hour with an inspector at this stage sees more than a full day at possession.
- Pre-possession. The deficiency walkthrough. This is where finish work, doors and windows, appliances, mechanical commissioning and cosmetic damage get written down. Whatever is not on the list is harder to argue later.
- Before the first year ends. Alberta's new home warranty starts its shortest coverage clock at possession. A walk-through with fresh eyes a month or two before that anniversary catches the settling, the seasonal movement and the things a first winter exposed.
What the warranty actually covers, and for how long
Under Alberta's New Home Buyer Protection Act, every new home carries four minimum coverage periods: one year on labour and materials, two years on the delivery and distribution systems — electrical, plumbing, heating, ventilation and air conditioning, five years on the building envelope, and ten years on major structural components, meaning the frame and the foundation.
Read that list next to the three inspection moments above and the logic becomes obvious. The coverage that runs out first is the coverage for the things an inspection is best at finding.
The warranty is a claims process, not a guarantee of quality. It works far better for a buyer who documented the problem early than for one who noticed it in year three.
The Calgary-specific items
- Lot grading. This is the single most argued-about item on Calgary new builds. The City requires the builder to submit an As-Constructed Grade Certificate, prepared by a professional land surveyor, engineer or architect, within 12 months of occupancy, confirming the lot was built to the City's grading tolerances. The City's own advice is blunt: do not landscape until the grades are confirmed. Buyers who put in a deck, a patio and $30,000 of hardscaping in their first summer sometimes learn this the expensive way.
- A winter build. Concrete poured late in the season, driveways and walks done in the cold, and backfill placed on frozen ground all behave differently. So does attic insulation blown in before the roof has moved through a full freeze-thaw cycle.
- Mechanical commissioning. Ask whether the furnace, HRV and any air conditioning were actually balanced and commissioned or just turned on. A house that heats unevenly on day one usually keeps doing it.
- The house next door. In an active Calgary community your neighbours are still being framed. Construction traffic, mud, nails in tires and a changed drainage picture are all part of year one.
Getting your inspector on site
Check the purchase agreement early. Builder contracts vary on whether an independent inspector may attend, at what stages, whether they must be accompanied by a site supervisor, and how much notice is required. That is a question to settle before you sign, not the week before drywall.
Choose someone who does new construction specifically — it is a different job from inspecting a 1970s bungalow. How we suggest choosing an inspector applies here too, with that one extra filter.
And have a REALTOR® with you from the first showhome visit rather than after you have signed: why that timing matters.
What to actually check at the walkthrough
- Every window and door — operation, locks, screens, seals, scratches in the glass.
- Every tap, drain and toilet run at once, then the basement floor drain and the hot water tank.
- Furnace, HRV and any AC: run them, listen, and check every register moves air.
- Floors for lippage and squeaks, walls for boarding seams and nail pops, ceilings for cracking at corners.
- Cabinet doors and drawers, appliance operation, and whether the model numbers match your selections.
- The electrical panel labelled properly, GFCI protection where it belongs, and every switch mapped to something.
- Garage: door operation, safety reverse, weather seal, and slab drainage.
- Outside: grading away from the foundation, downspout discharge, weeping tile, and whether the driveway and walks are poured and to grade.
Take photographs of everything you list. The resale final walkthrough is a lighter exercise than this one — on a resale you are confirming a known house has not changed; on a new build you are documenting a house for the first time.
How the deficiency list actually gets resolved
Writing the list is the easy part. What determines whether it gets fixed is how it is recorded and what leverage exists at the moment you take possession.
- Get it in writing and get a copy. A verbal acknowledgement from a site supervisor is worth very little in month four when that supervisor has moved to another community.
- Ask for dates, not intentions. "We will look after that" is not a commitment. A date is.
- Understand what can be held back. Whether anything can be retained at possession for outstanding work, and on what terms, comes from the purchase agreement. Read it before you need it.
- Separate seasonal items. Driveways, walks, landscaping and exterior paint are routinely deferred for weather in Calgary. That is normal — but the deferral should be documented with a season attached, not left open.
- Know where the warranty provider fits. If the builder does not resolve something, the warranty provider is the next step, and it has its own process and its own deadlines. Missing a warranty deadline because you were waiting politely is the most avoidable loss in this whole exercise.
This is also why we do not treat the pre-possession walkthrough as a formality. It is the last moment where the incentive to fix things is fully on the builder's side of the table.
