I'm aware of very limited cases in which there is minimum density zoning on lots. It is just that given a vacant lot within a demand area developers are going to naturally build the highest density legally allowed. I'm fairly certain you could buy an apartment building in Manhattan, demolish it, and build a picket-fence house there. It was just lose you tens or hundreds of millions of dollars so no one has done it. From what I can tell the way that interactive was constructed it would also highlight a lot if it fell into the category you mentioned but I can't find any where this is the case. It is a one-side problem and to pretend like it is two-sided is a bit detached from reality.
