I recognize this is enormously frustrating for people with families, but the reason this is happening is because there's a shortage of housing for single people, and so while there is demand from families, it makes more sense for builders to meet the unsatisfied demand for single people first.

We have more demand for single apartments than ever before because of changing household size dynamics. People are staying single longer and also living longer and thus more likely to become widowed.

The only way out of this problem is to enable more building of housing to more balance the demand of single unit apts with larger unit apartments.

It's also worth pointing out in crowded cities like San Francisco that large numbers of single people band together as roommates and rent family sized units in order to afford rent, and due to a general shortage overall.

When those single individuals are able to move out into a smaller apartment, it starts freeing up the shared family size units.

Banning single units is extremely counterproductive and overall raises prices for families in situations like these.
