I live in Soviet-style housing in Poland. The antisocial behavior of some tenants (it seems that there's always at least one) is something you learn to live with. Over the years, you start ignoring the occasional puke in the hallway or automatically put on headphones when someone next to you starts blaring loud music again. All in all, given how much people pay for such flats in Poland, my guess is that it would be totally acceptable for most people to deal with the inconveniences, if the flat was free as a part of the UBI.
Many countries do this by putting legal limits against gentrification.
As does creation of market rate housing[0], even in the short term.
What does that even mean? I'm not aware of any country that restricts the change in the income mix of housing, or the renovation of dilapidated housing by new residents.
Here are few examples among some EU countries: setting a minimum density and number of floors in urban areas to prevent "mcmansions".
Mandated commercial areas (aka shops) on the ground floor on new buildings.
Requirements on walkability applied to new road design to prevent sprawls e.g. limit cul-de-sacs.
Minimum and maximum percentage of buildings for industrial / office / shop / domestic use.
Minimum and maximum apartment size.
Tons of limitations on renovation of historical buildings.
A lot of this stuff makes it very difficult to quickly transform an already urbanized area into a bunch of super-luxury villas or similar.
It would provide housing for people on UBI, but because it’s operating on a thin budget, over time it becomes less desirable.
Now, it’s not always the case _if_ you can get the tenants to coöperate and pitch in on basic maintenance and keep anti social behavior at bay ala Singapore, but my feeling is we’re not of the same mindset as Singaporeans.
