A surprising amount of LA's economy is just warehouses. This could have an interesting effect on the cost of housing in LA, which would have an effect on Phoenix, which has seen massive growth in warehouses as LA has gotten expensive
The vast amount of warehousing in SoCal is in the Inland Empire, the logistics capital of the country, not LA proper. There's very little warehousing being done in LA and there's still ample land in the IE and high desert areas. It should have zero effect on housing prices in the area, they already moved further inland since ecommerce took off 20 years ago and only accelerated since the pandemic.
Housing won't be affected in LA because the issue is zoning + cost to get started. There are too many reviews blocking housing; it isn't blocked by warehouses being "more valuable" than housing in those lots
