Something that, if I'm understanding correctly, is a bit different from the type of grandfathering versus retroactivity that has been discussed--an interesting twist--is found in Florida Statute 718.110(13).
The page I saw this on was a search result, so I'm not sure if the link will hold (and of course, if someone is reading this at a future date, the info may have changed), but I'll try posting the link:
Statutes & Constitution :View Statutes : Online Sunshine
(I selected year 2013, the latest year available in the selection box at the time I'm doing the search.)
718.110(13) is almost at the bottom of this very long page.
This is in the section for condominiums; I didn't look up whether there's any info for HOAs.
As of tonight, when I pulled up the page, it reads:
"An amendment prohibiting unit owners from renting their units or altering the duration of the rental term or specifying or limiting the number of times unit owners are entitled to rent their units during a specified period applies only to unit owners who consent to the amendment and unit owners who acquire title to their units after the effective date of that amendment."
I should say I have no idea whether the page is current or is applicable to anyone's particular situation; I'm not an attorney or real estate professional and so am not giving legal or professional advice or information, and no one should rely on what I'm posting in their decision making. I sometimes misunderstand things, and even if I do correctly read and understand something, I don't have the background and haven't done the research that would be required to know if there's something else somewhere (beyond any particular paragraph I'm looking at) that would trump/change/supersede/reverse it. I'm just someone who's owned a couple of condos in the past and is considering (not without considerable trepidation) doing so again and so tries to be an informed consumer as much as possible. So people should consult an attorney for legal info/interpretation.
In my opinion, since joint ventures (like condos and HOAs) can only work optimally
for everyone over the long term if people put fair-mindedness above expedience, the original documents (absent compelling circumstances) are probably the best anchor, especially in a situation where a change would result in some residents winning and some losing. As much as I personally (as an owner occupant) would have benefitted if my last condo had had stricter rental guidelines (in fact, I'd still own it and wouldn't be posting all the time on City-Data about my search for a home!), I nevertheless wouldn't have wanted to see a rules change as I don't think it's right (I'm speaking golden-rule right) to pull the rug out from under someone who bought under certain existing documents that conferred specific use-of-property rights.
But I thought this was an interesting approach (trying to find a middle ground to achieve some mitigation of damage in situations where this does occur).
