It's even divided across the city's different climate zones (San Francisco is small, but can have huge differences in weather from one side to the other).
I recall a SoCal city even offering free consultation for native gardens.
The bank doesn't own the house, they just have a significant lien against it. Maybe a potato potato situation (how are you supposed to spell that phrase π€), but it is an important distinction.
Landlords can get pissed if you paint the walls/change appliances/remodel/etc., but so long as the property is properly insured (and you make your loan payments on time) the bank probably isn't going to bother you.
Landlords can
and do
place restrictions on quiet hours, guest policy, who is allowed to live there, etc. Owning is definitely different.
