Every Calgary buyer who looks at homes built in certain decades eventually hears the same three words: Poly-B, aluminum wiring, unpermitted work. Most of them go and get a repair quote, decide the number is manageable, and carry on. The repair quote is almost never the part that hurts. What hurts is the insurer, the lender and the appraiser, each making their own decision on their own timeline, none of which is your timeline.
What this article is not
It is not an explanation of what these items are or how risky they are. We have written that up properly elsewhere and there is no sense in doing it twice. Read those first if the terms are new to you, then come back, because what follows assumes you already know what you are looking at.
This is about the consequences that arrive later — the ones buyers do not price in because they are not property problems at all. They are transaction problems, and they show up in the three weeks between writing an offer and getting the keys.

Insurance is a condition you did not write
Your offer has a financing condition and probably an inspection condition. It almost certainly does not have an insurance condition, and yet you cannot complete the purchase without insurance in place. Your lender will require proof of coverage before funding. So there is a requirement sitting in the middle of your transaction that nothing in your contract protects.
For most homes this is invisible, because coverage is routine and the call takes ten minutes. For a home with Poly-B, aluminum wiring, an older electrical panel, an aging roof or a basement somebody finished without a permit, it is not routine. Insurers take their own positions on each of these. Some will not write the policy. Some will write it with conditions attached, such as remediation within a set period, or an inspection by a qualified trade, or a specific deductible arrangement. Some will write it and price it differently. Which insurer does which varies, and it varies over time.
I have never once seen this go badly for a buyer who called an insurer during the condition period. I have seen it go badly several times for buyers who called in the last week before possession, because at that point every option is expensive and the only remaining lever is panic.
Call an insurer about the specific address while your conditions are still in place. Ask them directly about the items your inspector flagged. It is a short call and it is the highest-value fifteen minutes in the whole transaction.
Get the quote before you waive, not after
The sequence that works, in order, and the order is the point.
- Inspection first, so you know what is actually there rather than what the listing implies. An inspector identifies; they do not usually quote.
- Trade quotes second, from people who would do the work. A plumber for the supply lines, an electrician for the panel and the wiring. Real numbers on this specific house, not a range from the internet.
- Insurer third, with the inspection findings in hand so you can describe the house accurately and get an answer you can rely on.
- Lender fourth, because if the insurer has attached conditions or the appraisal is affected, your lender needs to know before it funds and not after.
- Then decide, with every number in front of you, whether the price still works.
This takes about a week of calendar time and almost no effort. Which is exactly why the condition period has to be long enough to contain it. A ten-day condition period in a competitive situation can be genuinely too short for this sequence on an older home, and shortening conditions to win a house you then cannot insure is a poor trade.

What the lender and the appraiser do separately
Buyers tend to think of financing as one decision. It is at least two, made by different parties who do not talk to each other much.
The lender makes a credit decision about you and a security decision about the property. Lender policies on properties with known deficiencies vary, and so does what they will require — a holdback, a completion of work before funding, an updated appraisal, a specific document. There is no universal rule here and anyone who quotes you one is guessing. Your broker or lender is the only source for what your lender will do on this property.
The appraiser is doing something different again: forming an opinion of value. Significant deferred maintenance, obvious deficiencies or work done without permits can all bear on that opinion. If the appraisal comes in below the purchase price, the shortfall lands on you in cash, and it lands late — appraisals are typically ordered after conditions are being worked through, not before.
The practical consequence: a home with these items is not only a home that needs repairs. It is a home where two more parties get a vote, and both of them vote after you have committed emotionally.

Permits: the one that reaches furthest
Of the three, unpermitted work has the longest reach, because it is the only one that does not fix itself with a cheque.
Poly-B can be replaced. Aluminum wiring can be remediated by a qualified electrician. Both are finite problems with a beginning and an end. Work done without a permit is a record problem, and records outlive plumbing. It follows the house through every future sale, every insurance renewal and every conversation with the City.
It reaches into insurance, because a loss originating in unpermitted work is exactly the situation where an insurer starts asking questions. It reaches into financing, because an appraiser may decline to give value to a basement that was never approved, which can mean the finished square footage you are paying for does not count toward the value your lender is lending against. And it reaches into your own eventual sale, because you will have to answer the same question the seller is answering now, and you will be answering it to a buyer who has read this sort of article.
What the City requires, what it will do about existing work, and whether a permit can be obtained after the fact all depend on the specific work and the specific property. That is a City question and worth asking during conditions rather than assuming either the best or the worst.

What it means for the number you offer
All of this belongs in the price, and it belongs there when you write rather than in a renegotiation later. Once conditions are being removed, your leverage is largely spent and the conversation gets adversarial fast.
The way I put it to buyers: you are not paying for the repair, you are paying for the repair plus the friction. The plumber's quote is the smallest line. Add the coverage you had to arrange on less favourable terms, the work an insurer required on a timeline you did not choose, the value an appraiser did not give you, and the discount the next buyer will ask for. That total is the real cost, and it is the one that belongs in the offer.
This cuts both ways, and I say so to sellers too. A home priced as though these items are not there will sit while buyers discover them one at a time. A home priced honestly against them often sells quite normally, because the buyer is not being asked to absorb a surprise.

Where to start
None of these three items should stop you buying an older Calgary home, and some of the best-built houses in this city are exactly the vintage where you find them. Established communities with mature trees and full-size lots did not appear in the last decade, and the trade for that is a house with a history.
What should stop you is going in without the sequence. Inspection, trades, insurer, lender, then decide. If the seller will not give you a condition period long enough to run it, that is information about the seller worth weighing on its own.
If you have an address in front of you and want to know what to expect before you write, that is a short conversation, and we have had it a great many times. Bring the inspection report if you already have one.
