I too am curious to see how many landlords actually allow inspectors inside. As stated in the article, the landlord can refuse entry into their property. Chances are the courts aren't going to force entry into each rental, primarily because they're likely occupied, secondarily there isn't enough manpower for that. Landlords will be given 3-4 week notice prior to the inspection, seems reasonable enough. The dozen or so items that were listed off all seem pretty fair in my opinion. Certainly issues are going to arise from these changes, but it also has great potential to weed out slumlords. I get that you're thinking on a much larger scale, but if landlords/investors are doing what they're supposed to be doing, and keeping their units in a habitable condition, they shouldn't be running for the hills, leaving their properties behind.
Here's another link, to complement yours (the last 10 paragraphs or so are interesting) :
