Why buyers worry about the envelope
The building envelope is the outside skin: walls, windows, roof, balconies and the joints between them. When it lets water in, damage happens inside the wall where nobody sees it. Many buildings put up in coastal BC from roughly the late 1980s through the 1990s had envelope failures and were later repaired at owners' expense, which is where the phrase leaky condo comes from.
Newer buildings are built to different standards, but envelope, roof and window problems can occur at any age, so the question to ask is what is known about this building, not just when it was built.
Ask these questions
- Has the envelope been repaired or remediated, when, and who did it? Ask for the engineer's report and completion documents.
- Are there warranty or legal claims connected to construction defects, and what is the status?
- What does the depreciation report say about envelope, windows, roof and balconies over the next ten years?
- Do the minutes mention leaks, moisture testing, staining, mould or repeated repair patches?
- When were the roof, windows and parkade membrane last replaced, and what is the expected life?
What an inspection can and cannot show
A home inspection of your unit checks its visible condition and can flag moisture at windows, balcony doors and exterior walls. It cannot assess the whole building. For that you depend on the strata documents, and for a building where the age or history gives you concern, a conversation with an engineer or a lawyer who knows strata purchases is worth the cost.
Weigh the price
An older building with a completed remediation, a healthy reserve and a current depreciation report can be a good purchase. A building with unresolved envelope issues can still make sense at the right price, but only if you have priced the risk of a levy and can afford it. If you cannot get straight answers from the strata or the seller, treat that as information.
Frequently asked questions
Does a remediated building carry a stigma?
Some buyers and lenders are cautious, but a well documented remediation with a current report can leave a building in better shape than one that has never had its envelope checked.
Should I book an engineer?
For an older building, or one with worrying minutes, it can be worth it. Your agent and lawyer can advise on whether it fits your situation.
Where do I find the repair history?
In the minutes, the depreciation report and any engineering reports in the strata document package.
