Yes indeed it is. The feds would have to find some financial incentive which could strongarm the states into passing laws overriding local zoning ordinances, in the same way that they used the threat of withholding highway funding to coerce states into establishing speed limits and the 21-year minimum drinking age.
But most of the building restrictions are coming conservative older homeowners at the local level. There's only so much Harris can do at the Federal level to reduce state and county bureaucracy.
The supremacy clause exists as does the interstate commerce clause. The existence of HUD is proof the the federal government has the ability and constitutional authority to cut through this red tape when so motivated. That said, I would suspect protracted legal battles, with uncertain outcomes given SCOTUS, around any attempt for the federal government to cut through local zoning regulations.
So, we're just going to ignore the very real lumber shortage that's affecting homebuilding? We're also going to ignore the fact that our immigration laws have reduced the labor available to build houses? After all, it's pretty hard to build houses without material and labor.
Lumber prices are cheaper than they were during their pandemic highs, sure, but they're still roughly double the price of what they were on average pre-pandemic.
While immigration has increased, it hasn't increased at a rate to replace Americans leaving the labor market. Overall, the amount of labor in the United States has decreased. That dramatically impacts labor-intensive industries, such as construction.
So, we're still faced with a high cost of materials and a shortage of labor.
streamline permitting
knock down ridiculous fees and paperwork
don't try to tax the builder out of business
don't put stupid mandates about forcing builders to sell to demographics the current administration prefers
basically, get out of the way and homes will be built
