Zoning has been the biggest roadblock to creating more affordable options for middle class and families. You get better-priced options with cheaper construction options for townhomes, flats, walk-ups, detached, and duplexes and triplexes. You build quality modest homes in areas where land values are not that expensive and this is how you get affordable family and workforce housing. The issue is as many have pointed out is nearly impossible to build much of this stuff in cities today as Zoning has outlawed much of it.

^^^ In Canada, this used to be the standard for market created modest family housing. These non-detached townhome courts and duplex courts were the preferred methods of building in the 50s 60s and 70s in many Canadian cities. For many young families, or immigrants and newcomers into Canada after this was the next step in housing after the apartment got too small for the growing family. I grew up in this type of housing and I remember having all my friends to play on the playground in the centre of the court.
In the USA in many places such as Houston, Dallas, etc you still get this type of housing being built. The USA has kept this going as many developers will build these apartments to spec in well-positioned areas with good access knowing that families and young people will scoop them up.

In Canada though and older USA cities, this style of housing is now far too complicated to build these days which is a shame. This family style of density is banned in many family-oriented neighbourhoods.
There just isn't enough housing being built. Housing only becomes "affordable" if put up with a discount on land and materials or if it is older housing stock. Places that have cheap housing either build lots of it, having lots of old housing still around or in a perfect world both.

Of course, like clock-work the predictable Canadian arguments of mystical shadow Chinese money that is the sole reason of housing unaffordability when simply Canadian large cities are just not building enough housing. Vancouver and Toronto are not doing anything just bringing a few units to market each year.
You won't find examples of the type of housing I just posted in Vancouver or Toronto. Point towers condos and SFH won't ever make a city affordable.
