Blogger and programmer Eric Fischer has an excellent post up on his site where he looks at: “Employment, construction, and the cost of San Francisco apartments.” It’s worth a good solid read.
What he did was dig deep into whatever data he could find – the data goes back to the beginning of the 20th century in some cases – to try and figure out a solution to San Francisco’s housing affordability problem.
Many (including myself) have argued that, at least part of the solution, is to build more, not less, housing. However, others, such as Tim Redmond of 48 Hills, have argued that building more market-rate housing would simply exacerbate the current situation.

In Eric’s analysis, he looked at everything from median rents and new housing units constructed (above graph) to annual wage growth and income inequality. I particularly liked his summary of the city’s various building booms.
In the end, here’s the conclusion that he came to:
“In the long run, San Francisco’s CPI-adjusted average income is growing by 1.72% per year, and the number of employed people is growing by 0.326% per year, which together (if you believe the first model) will raise CPI-adjusted housing costs by 3.8% per year. Therefore, if price stability is the goal, the city and its citizens should try to increase the housing supply by an average of 1.5% per year (which is about 3.75 times the general rate since 1975, and with the current inventory would mean 5700 units per year). If visual stability is the goal instead, prices will probably continue to rise uncontrollably.”
By visual stability, he is referring to maintaining the current urban fabric of San Francisco just the way it is. In other words, he is making the link between preservation and affordability in a prosperous and growing city.
Intuitively, this makes sense to me. It’s unrealistic to think that you can maintaining some level of housing affordability without allowing supply to increase alongside demand.
At the same time, I do not believe that preservation needs to equate to no changes whatsoever. Urban preservation, to me, should be about dutifully respecting the past while still looking firmly towards the future. And that’s how I believe successful should be approaching this problem.
About a month ago, a reader of ATC and friend of mine suggested that I write a post on some of the common misconceptions that people hold about cities. I immediately thought it was a good idea and so I started a draft post with some of my initial thoughts.
Over the past couple of weeks I’ve been collecting fallacies as they came to me, waiting until I reached a nice round number like 5. Well today, I reached that number. So here are 5 misconceptions that I think people often hold about cities. If you have any others, or if you disagree, please share your thoughts in the comment section below.
1. Adding more lanes will solve traffic congestion
There’s a saying I read somewhere: Adding more lanes to solve traffic congestion is like loosening your belt to deal with obesity. I can’t remember where I read it, but I like it a lot because it gets at the heart of this fallacy: Trying to build our way out of traffic congestion has proven time and time again to be a losing battle. In fact, it has been shown to make traffic even worse as a result of “induced demand.” The more roads you build, the more people drive.
2. A suburban home is always cheaper
While it is true that the direct cost of a suburban home is usually less than one in the center of a city, many people often neglect to factor in the indirect costs of a home purchase – the biggest of which is usually transportation costs.
As you move out from the center of a city and home prices start to fall, I like to think of it as transfer from housing costs to transportation costs. In other words, what you save on the price of your home, simply gets used to pay for a car (or perhaps a second car), as well as the additional time you’re going to spend traveling.
So how much is an hour of your time worth? Have you ever attached a value to it and added it to the price of your home? Because if you factor in transportation costs and your time, you might find that your suburban home is actually more expensive.
3. Opposing new development and advocating for affordable housing is a responsible way to build cities
Community opposition is a big part of the development game. But what a lot of people don't think about is that when you oppose or stop new development (let’s say it’s residential), the demand for that housing doesn’t go away.
In fact, all it does is create more pressure on the housing stock that does exist and foster an environment where the rich will starting outbidding the poor for housing. More simply, you end up creating a supply constrained market and that drives up home prices. Demand > supply. So in reality, opposing new development and, at the same time, advocating for more affordable housing is a contradiction.
As a comparative example, let’s think about another basic human need: water.
Imagine that you could only buy water from stores (it didn’t come out of taps). But that every time the delivery people were trying to bring more water to these stores, that there was a group of people who fought and opposed them. These opposers already had enough water for themselves and they didn’t want additional water being sold as it would bring new customers into their local grocery store and disrupt their way of life.
This, of course, caused the price of water to rise as the rich people started offering more for the water. This in turn made it difficult for the poorer folk to afford any water at all. But instead of allowing the delivery people to simply deliver more water, it was decided that out of the water that they have, that some of it should be earmarked as “affordable water” and priced accordingly. That would guarantee that the poorer folk could still have some.
Does that sound like a sensible solution to you?
4. Developers don’t want to build big apartments
Here in Toronto there’s a somewhat pervasive belief that developers don’t want to build big condo and apartment units. The thought is that small units are more profitable and so developers are doing everything they can to squeeze people into small units. But I’ve argued before that this isn’t the case. It’s far more nuanced than that.
To illustrate this point, imagine you’re a developer debating between building two 500 square foot condo units or one 1,000 square foot condo unit. If you build the two 500 square foot condo units you’ll need 2 x kitchens, 2 x entry doors, 2 x separate color selection appointments, 2 x separate PDI appointments, and you’ll have to pay development charges on two 1 bedroom units (to name only a few things).
On the other hand, if you build one 1,000 square foot condo unit you’re only going to need 1 of each of the items listed above and you’ll be paying development charges on only one 2 bedroom condo unit (which currently works out to be less than what you’d be paying for the two 1 bedroom units – it’s not quite double).
Which one do you think would be cheaper to build?
5. Technology is going to make cities irrelevant
Lastly, during the dot com era there was a growing belief that technology and the internet were going to make cities and real estate irrelevant. Capital was flowing out of real estate and into tech companies, because that was seen as the future. Bricks and mortar were passé.
But since then we’ve learned that it’s actually the opposite. Paradoxically, technology has made cities even more important. The returns to being smart and talented are huge in the right place. So much so that our biggest concern shouldn’t be whether cities are going to become irrelevant, but whether we’re concentrating too much wealth and talent in only a select few.
So there you have it, 5 misconceptions about cities. I’m sure there are many others, so I’d love to hear from you in the comment section below.
Regular readers of this blog will know that I’m a big supporter of road pricing. I think it’s an incredibly efficient way of reducing congestion, improving regional productivity, making us more sustainable, and funding other infrastructure, like transit.
But one of the arguments I often hear against road pricing is that it’s unfair to force a segment of the market out of their car if there’s no good alternative (ie. proper transit). And even if the revenue produced from road pricing goes towards transit, we all know that new infrastructure takes a very, long, time.
So we end up with a chicken and egg problem: Road pricing is a great way to fund transit, but it’s difficult to implement without the proper transit in place. So what should we do? What comes next?
I have two thoughts.
First, road pricing doesn’t necessarily mean that you can no longer drive without paying. Effective road pricing matches price with demand. Therefore if there’s nobody else on the road, you wouldn’t be paying (or at least wouldn’t be paying much). This is what makes it efficient—it adjusts. So for somebody without the willingness to pay for peak congestion pricing, they could still have the option of driving at another time. Go in early or go in later.
But what it does mean is that no matter what time you’re driving, the road could be priced so that it actually functions again. In Toronto today, many of our roads are completely failing. Demand greatly exceeds available supply (the amount of road we have) and so you can’t use them to get anywhere in an efficient way. So what we have is equal access to terrible non-functioning roads.
Second, there’s no such thing as a free lunch and nobody said it was going to be easy to build phenomenal infrastructure. We all complain and say we want it, but when push comes to shove, are you willing to open up your wallet and pay for it?
So I say forget pontificating about chickens and eggs and just do it. If we priced roads and setup other appropriate revenue tools, I’m sure there are some financial wizards in this city that could use tax increment financing or other mechanisms to ensure that we get shovels in the ground today for the new infrastructure that we so desperately need.
These are important discussions to be having no matter what city you live in. I would love to hear your thoughts in the comment section below or on twitter.
