That's quite a parking lot. The law says that for a X square feet of floor space, you have to have Y number of parking spaces. The law makes no distinction between a furniture store (which is what we have here) and a movie theater, even though furniture stores by their nature need a lot of floor space for very few people.
I suppose you could defend this by saying that with the giant parking lot, buildings like this could some day be re-used for some more people-dense purpose; but the special economics of furniture store real-estate makes this highly unlikely. Incidentally, just to the left of the edge of the frame here is the site of the legendary and now demolished Coral Court Motel.
