If you are a neolib then it is up to the building owners and residents. If you are an ancap the free market will solve it (kek) with the residents moving away from the crumbling building, forcing the owners to invest in maintenance.
No matter what your ideology is, one simple fact is that it is easier and cheaper to do maintenance on a high rise residential building than an entire town. It is also more energy efficient (from heating/cooling to transportation).
