It’s a similar problem in Canada from what I can tell. I visited Vancouver BC for work a few years ago and the place I stayed in was an Airbnb rental in a building that had very clear markings stating that those types of rentals were not allowed. Nobody is checking nor enforcing that stuff, but at least if someone was made aware, something would happen to stop it? In the US it’s just a free-for-all for capitalists and landlords.
A house down the street from me (I live in the US) was torn down and replaced with a main house, and a second separate house on the back of the property. Both are rented out separately at what I’d imagine are exorbitant rates (for reference, a house down the other direction on my street is being partially rented for $5400/m and the other part at $3800/m). The driveway runs alongside the right side of the house and because 2 different tenants rent each house, the front house can’t use the driveway at all because they run the risk of blocking the other tenant. So now all of their cars litter the street (7 of them at one point when they had friends over).
I fucking hate landlords.
I live in Florida too and see this all over my city. Tons of houses have been haphazardly carved up to make into apartments. It’s a double-edged sword because I want everyone to have a roof over their heads, but they are charging ridiculous rates that folks can’t afford anyway.
