Construction is a big part in some locations but it doesn't make housing unaffordable, merely expensive.
From memory:
Tearing a $2 million single family house and putting 6 apartments there would allow you to charge $3k rent. Build taller and rent drops even lower. This is assuming construction costs of $500 per sqft.
