Very curious to see a study comparing the average cost of a parking spot (including free parking) to the average rent for living space, both normalized e.g. per square foot. And also an estimate of just the land component of rent, ignoring building/maintenance. I suspect the answer wonāt be pretty.

Strongly agree. From our 2023 Housing Nationalism paper: "[R]eactionary nationalism operates as part of a cultural toolkit for solving problems, where entrepreneurs practiced in the tool can advance their own interests by seeking out and magnifying problems to solve."

Still stunned every time a planning prof looks at the landscape of rising rates of doubling up and concludes thatās entirely due to peopleās preferences. And that the strong correlation of doubling with rents is purely coincidental. And that adding homes wonāt change doubling up rates.

Randomly remembered going to this concert, and was trying to think how this song (originally from 1982!) fits in with current events. Back then it felt like a future to try and prevent, now it feels like a stage we already passed, roughly around the āthey are eating the dogs and catsā phase.

Super interesting article. And yes, high vacancy rates in non-market housing is a sign of poorly designed policy. Also, pretty depressing what some seem think a "solution" to this misalignment is.

Such a confused article. Vacancy rate for āaffordable housingā is not a meaningful metric. That metric is useful for housing allocated by market mechanisms, but non-market housing gets allocated as soon as itās available. We should look at wait lists instead, 8000+ long and ~2 years wait time in NS.

Could not help myself, ran the numbers. Scrapping the Capped Assessment Program (similar to California's Prop 13) so that incumbent homeowners pay the same effective rates as newcomers or renters would yield a substantial tax revenue increase for HRM. The CAP has grown into a large fiscal liability.

Epic thread on budget meeting and potential property tax increases in Halifax, and I wonder how much can be raised simply by killing the CAP that has protected (predominantly rich) incumbent owners from paying the higher effective tax rates newcomers and renters face.

I have way too many thoughts on the FCM advocacy paper on why property taxes aren't enough for municipal revenue:

Extracting value on the front end of development (community benefits) instead of the back end (taxes) is eating the seed corn. It'll never produce as much community benefits as planting a good harvest and sowing it when it ripens.
