Marlon Bray over at Altus recently shared the above chart on LinkedIn. Normally I only go on LinkedIn about once every quarter, if that. But thankfully our team likes to follow nerdy charts and so it got circulated around.

The chart is from Statistics Canada (table 18-10-0135-01 to be exact) and what it shows is the % change per annum of their construction price index, going all the way back to 1989. It is good context for the massive cost increases that we are all currently working through.

Increasingly, I think that most people in the industry feel as if we're now reaching a tipping point. Costs -- both hards and softs -- cannot continue to go up like this. At some point supply will start to taper off or even shut off. The former has likely already started.

Our cost consultant, Finnegan Marshall, gave our team a presentation today on what's happening with construction costs in Toronto and across Canada. I've said this before, but hard costs are no joke right now.

One of the areas that they focused on was the impact that inclusionary zoning is likely to have on development economics here in Toronto. To illustrate the point, a sample high-rise condominium pro forma was used. Think something in the 30-35 storey range.

Assuming a requirement of 10% affordable (the policy details are still TBD), there is going to be a real cost to development pro formas that will need to be somehow paid for.

One school of thought is that land prices will simply adjust downward. In this case, the landowner would be the one paying. I don't think this will be the case (land prices tend to be sticky), but if they were to adjust downward, it would need to drop by $44 per square foot buildable to maintain the project's margins in this example. (That's $13.2 million on a 300,000 sf project.)

If, on the other hand, the price of the remaining market rate condominium suites were to increase to offset the cost of the affordable component, they would need to increase by $91 per square foot. This translates, in the above example, into a sticker price increase of approximately $60,000 per suite.

These numbers are, of course, not exact. That is not the point of this post. Every project is different. But hopefully it gives you an idea of some of the levers that will invariably need to be pulled when inclusionary zoning comes into force.

My sense is that this latter scenario is more likely to happen. I have yet to see land prices adjust downward in the face of rising costs. So all of this is likely to be bad for broad-based affordability, but good if you want to be bullish on market rate home prices.
