Rule of Thumb for Multi Family Unit Square Footage?

[Lucian Guadagnoli]

Good Afternoon BP forum!  

Is there a rule of thumb for how much square footage is 'typical' for a Xbr/Yba unit in a residential multi-family?  I realize this is highly subjective with a lot of variance, but there must be some average square footage per living unit that one could baseline 'cramped' units against 'spacious' units in an area.

Local building code? 600sqft/unit minimum?  Let me know your thoughts!

It will vary greatly by city and by submarket in that city. I'm most familiar with Texas markets and Houston and DFW generally have larger units than Austin and San Antonio. And  suburban properties generally have larger units than urban ones. Unit mix also varies between those scenarios too.
