Cosmetic Damage vs. Warranty Defect: Why Documentation at Possession Matters
The short answer
Cosmetic deficiencies noted at possession are generally the builder's responsibility to fix. The same mark noticed weeks or months later is much harder to attribute to construction rather than everyday living, which is why thorough documentation at your walkthrough matters so much.
Key takeaways
- Cosmetic issues documented at possession are the builder's responsibility; the same issue found later usually isn't.
- Warranty coverage generally distinguishes construction defects from ordinary wear or accidental damage after move-in.
- The pre-possession walkthrough record is what establishes a mark existed before you moved in, not after.
- Some builders set a short window after possession for reporting missed cosmetic items — ask what yours allows.
- When in doubt about whether something is cosmetic or a genuine defect, document it anyway and ask.
The core distinction between the two
Cosmetic damage is surface-level — a scuff, a small paint touch-up, a minor scratch — while a warranty defect is a genuine construction or materials issue covered under Alberta's 1-2-5-10 warranty framework. Both matter, but they're treated very differently depending on when they're identified.
Why timing decides who's responsible
A mark noted and photographed at your pre-possession walkthrough is clearly documented as existing before you moved in, which makes it the builder's responsibility to address. The identical mark noticed weeks later is much harder to attribute to construction rather than everyday living — from the builder's perspective, and often from a warranty provider's, it's reasonably treated as having happened after possession.
What typically counts as cosmetic
Small paint imperfections, minor drywall marks, small scratches on surfaces, or slightly uneven caulking are generally cosmetic. These are usually addressed if caught at possession, but often aren't covered once meaningful time has passed and the home has been lived in.
Ask about the builder's post-possession reporting window. Some builders allow a short period — often a couple of weeks — to report cosmetic items missed at the walkthrough itself. Confirm this window and use it if you need it.
What typically counts as a warranty defect
Issues with materials or workmanship — a failing seal, a structural concern, a system that doesn't function as it should — are generally treated as warranty defects rather than cosmetic issues, and remain the builder's or warranty provider's responsibility within the applicable coverage period regardless of when they're discovered.
When you're not sure, document it anyway
If you're not sure whether something is cosmetic or a genuine defect, document and report it regardless. It costs you nothing to raise it, and it's much harder to make the case later if you didn't. See our guide on submitting a clear warranty request for how to document it well.

Frequently asked questions
How long do I have to report cosmetic issues after possession?
This varies by builder — some allow a short window, often around two weeks. Ask your specific builder for their policy.
Does the 1-2-5-10 warranty cover cosmetic damage?
Generally no, cosmetic items are typically outside the scope of the formal warranty framework, which is why possession-day documentation matters so much.
What if the builder disagrees an item was there at possession?
This is exactly why photographing and getting items signed off at your walkthrough matters — it's your evidence of the home's original condition.
Can I still raise an item months later if I genuinely believe it's a defect?
Yes, particularly for anything that looks like a materials or workmanship issue rather than cosmetic wear. See our warranty framework guide for applicable timelines.
What if I have a home to sell?
That is common, and it is worth planning early. The timing question is how a builder's possession date lines up with the sale of your current home — completion dates can move, and carrying two homes or bridging the gap has a real cost.
