They did this in Japan. You're require to have an emergency sprinkler system for fires as just one example. If you don't have one, getting one installed is apparently around $20k so that prohibits lots of people from getting started renting out. Then as well they have to registered. If it's an apartment/condo building you have to get permission from the building management/home owners association. And I think it's max 90 days a year.
