So why are Multi-generational homes so rare?

To put it simply, there is confusion between the building code, planning scheme and some local councils about the risk and impact of the installation of a second kitchen and/or a separate of living quarters.  Even though there are examples of single leveled multi-generational  homes, (and the numbers are increasing),  these are on typically large lots located in the outer suburbs. Unfortunately there is unexplained resistance to multi storied varieties which will increasingly be relevant in an urbanising city not just here in Melbourne but in many other developing cities.

It couldn't be summed up any better than the owner of a Washington (USA) building company (Quail Homes).    “Quite frankly, the rules are outdated for today’s society.”

So, why does a housing system, which claims to assist in finding affordable and community focused solutions,  struggling with the Multi Generational housing concept?
