Taking a look at some randomly selected roads in Google Street View [1], it looks like it's been built at extremely low density, by most standards.
I mean, if you've building a single-storey home, then putting a double garage on the side, then a gap between properties two cars wide, plus a driveway with parking for two cars, then on-road parking for 3 more cars? Of course you're going to run out of land fast.

I've no idea whether it's a zoning issue, though.
