I had lunch with our realtor friend yesterday, we usually chat about housing, as he's in the biz. There is plenty of housing here, and plenty of new construction. There really isn't some zoning inhibition here about said new construction as the developers usually own the zoning boards. I've noted before, near me is a TON of new construction, nearly all apartments because for some reason they are easier to build, and younger folks don't have down payments/credit. This area is also "hyper=zoned".
At least near me, zoning is NOT some inhibition to development. Any time I'm in the 'burbs I see new developments going up everywhere. Traffic of course is a mess.
