It doesn't take a rocket scientist to understand that if you rezone a property to be more valuable to redevelop that it will be more expensive. It takes an expert in doublespeak to present the idea as an affordability path.... The highest density cities are not the most affordable.
one action towards affordability is to stop sending people letters that their house is now worth a million dollars. Change evalue BC to an index value. It's supposed to be for tax purposes right? Next examine the building code. We need to allow for people to build less expensive homes. Net zero is very expensive to build to. Plus it's not necessarily better since it doesn't look at things like embodied energy or waist etc. For xample: A quadruple pane window is not repairable. it's also more to produce and ship and install because of it's weight. My old house had single pane windows that were 90 years old. A rock went through one pane in the front from a car passing. Cost $100 to fix....
Upzoning appreciates the land underneath homes because... you can build exponentially more square footage, hence more homes for the same lot.
Land value =/= home prices fundamentally speaking, but the two will approach each other in cities where residential landmass is dominated by SFHs.
