Renting sucks. There's no stability, the expectation that you'll be priced out of a place, and none of the money or time you invest in anything there is truly yours.
'Single family' dwellings tend to have a small bit of yard space (not directly a plus for me), an air-gap with other units that helps with some noise abatement, and sometimes a choice of utilities (like Internet). There's room to park the nomad-mobile (the car that's required for efficient traversal of the many suburban wastelands and the gaps between cities).
If you own, rather than rent, you're able to change and modify many things.
There are still issues of BBQs, intense dryer scent bombs, and smokers. Parties, loud vehicles, and other annoyances too.
+++ my own ideal solution criteria +++
* Able to own
* Able to modify inside the walls
* Privacy of noise isolation
* Privacy of fresh air
* Internet choice (#1)
* Parking included (#2)
The privacy issues I see most easily resolved by requiring mechanical isolation spaces, similar to the old wetwalls, between units, above and beneath as well. My ceiling should not be directly hanging off of someone else's floor. The extra mechanical space also allows room for proper ducting of intakes and exhausts to allow a building intake of fresh air through a common filtration unit, and exhaust through a similar scrubber unit to remove particulate matter and minimize ecological pollution.
#1 Internet choice would happen after the last mile. The last mile being municipal fiber to ethernet links, and transit at high speed for base taxpayer cost to 2-3 peering points out of the local set. Real choice would be offered by competition at those locations. Peering points might be likely at government command and control centers (city hall, police hq, fire stations), or temples of information worship (libraries, schools, post offices?).
#2 Parking is the terminus of the inter-city and inter-state interlink that currently exists. This doesn't have to be per building. A 'cave of steel' like city could have interfaces (parking garages) at the edges, ideally with monitored space, even small storage boxes (garages) for cars. Naturally these would also be cargo terminals and there'd be a good transit system between them and everyplace within the city. This would require urban planning, mass transit and/or people-mover belts, and maybe an electric cargo drone delivery system. BTW, wouldn't an electric cargo drone delivery system be a lovely civic infrastructure aid? Completely eliminates the most annoying aspects of all current delivery services.
