[quote=Anonymous][quote=Anonymous]Lol no. Just build more housing. This isn't complicated to anyone but NIMBY trash.[/quote]

Another adorable argument from the cutest developer pets, the YIMBY.

Do you have any proof that upzoning will do anything that you think it will?

Something academic and researched with citations, not from the some YIMBY yokel blog.

This was a few minutes of search, but it’s all out there if you look.  I think that the conclusion you will find that more housing is good, trying to shoehorn in into existing neighborhoods is stupid and a waste of energy.

We can start here, with an interview with a UCLA and London School of Economics Professor.

Here is analysis how how upzoning worked elsewhere (links/citations within):

[i]But it appears that the end of single-family zoning wasn’t the real driver behind Minneapolis’ flat rent prices. The production of duplexes, triplexes and fourplexes has been very modest — just 53 units in 2021, for example — since the 2040 plan went into effect.

“The change hasn’t been that big,” said Alex Schieferdecker, a Twin Cities transit planner who’s analyzed city development data.

Rather, it appears that earlier parking reforms were responsible for a boom in new apartment buildings, and the subsequent rent moderation. Minneapolis has eliminated minimum parking requirements for new developments — first for areas near frequent transit lines in 2015 and later for the entire city. [/i]

Another article pointing out that trying to force housing into established neighborhoods is a waste of time and energy when better solutions exist.

[i]Because redevelopments tend to be costlier, the effect of upzoning would be much stronger when it is applied to vacant parcels or underutilized parcels. When citywide blanket upzoning is politically difficult, localized upzoning should target vacant and underutilized parcels. The effect of upzoning in built-up areas tends to be weak. I anticipate a moderate impact of upzoning on housing developments in a built-up city such as Portland where less than 10% of land is vacant. Geographically, I expect to see a more prominent effect of citywide upzoning in suburban and fringe areas where developers can find more vacant and underutilized land… Simply permitting residential buildings in commercial zones or rezoning commercial zones into mixed-use zones can create a huge potential for multifamily housing development. Another advantage of rezoning commercial zones into mixed-use zones is that rezoning in commercial districts usually faces a lot less neighborhood resistance compared to upzoning in single-family neighborhoods. Therefore, modifying commercial zones to allow mixed-use developments could be another policy option to increase housing supply when large-scale upzoning in single-family neighborhoods is politically difficult. [/i]

Of course, neighborhoods and areas and demographics  are different.  In poorer neighborhoods the upzoning very well might cause a lot of gentrification…

[i]We find that upzonings that occurred between 2000 and 2007 are associated with a five to nine percentage point increase in the share of White people in that area. This influx is particularly notable [/i]

We could do this all day.  Do you have…anything besides “more is gooder!”  Anything that takes into account efficiency or possible unintended consequences?[/quote]
