Trailer parks have prefabricated housing rather than true trailers. These prefabs can technically be moved, but not easily or cheaply, essentially tying them to the lot. RVs can be moved easily and cheaply.

So no, this is not exactly a trailer park because it separates housing from the real estate.

I'm not pitching the RV Parking Garage concept as an ideal or even plausible solution, but as an example of a way to disrupt the housing market in developed metros.

My goal is to hear some other ideas to decrease average rents while requiring little to no government/regulatory involvement.

> requiring little to no government/regulatory involvement

I think you lose this battle as soon as you start providing residences to people. I’m not a lawyer, but I’m pretty sure that once people are living and sleeping somewhere you’re subject to zoning laws and fire codes and stuff.

With that said, the current housing situation in the US is a mess, so I’m all for reform. I’d like to hear ideas too. I personally can’t think of a solution that sidesteps regulation without becoming a slum full of desperate people, though.

Those desperate people are who most need help. Maybe improving the quality of life in "slums" is where the hacking should take place. But those improvements typically leads to gentrification and higher average rents.

Is there a way to hack governmental reform? Maybe an organization that hires lawyers to find weak zoning laws in jurisdictions where a challenge is likely to succeed, and then tests those laws in court? (Now I've reinvented a thinktank.)
