📍Vancouver, BC
Yes, at least for the ownership segment. Vancouver Open Data has all properties by assessed value. There is some difficulty in separating out residential properties, but a mixture of zoning codes and effective property tax rates can do this.

And another look at the housing success in Edmonton, and the troubling possibility they might walk some of this back.

100% The main guy behind this lives kitty-corner to the school site on something like the 4th floor of his 12 storey condo building. It is petty NIMBYism at its worst.

I have so many thoughts on the “I don’t think the city cares” part. I think you are 100% right that the city only cares about this in new buildings and not once people have lived in it for a while. For a myriad of reasons that are mostly stupid. One could write a book about that.

And a good follow-up post by Deny to zoom into the financing side of Edmonton’s housing boom.

Yeah, I am surprised how often I use this from the phone now.

Not to worry, I have it on high authority that the fees just “come out of the land”…

Just keep the labels in non-transformed units, only transform the scale?

Fun opportunity to play with my new toy... canviz.mountainmath.ca/plot?v=74657...

The French part probably needs some refinement, I just told Claude Code to make French translations. Except for the data part, there it takes the official French labels and names from StatCan.

For City of Vancouver that’s in the open data catalogue. And you can also view it if you click into individual properties on my assessment viewer. For other parts it’s unfortunately not open data, the province should open that up…

Forgot, data selection and graphs can be shared, here is the live version of the data from the demo video.
(The image and title/description in the link preview unfortunately does not adapt, that would require having a backend server instead of just a static webpage for the app.)

Yes, this is bad and I would like to “Report a problem”!!!

Sigh. Not clear to me why this has to be done on 48h notice instead of, say, 2 week. Just because they can I guess, a good dose of harassment mixed in there….

What is that? Never heard of unit inspection for the entire building.

Although the process of integrating through this might be more cumbersome. With Claude writing code to get the data and explore it at different dimensions and read the output, then making changes and/or adding text and graphs, and maybe going back to exploring dimensions and tweaking things?
January 13, 2026 at 2:53 AM
Process question, I am guessing this could have been implemented by asking Claude to write a quarto document that integrates data ingestion, manipulation, visualization, and accompanying text. With all numbers in text quoted from R variables? Which would enforce the “no making up data” rule.

It’s all your fault!
