young person living in 55+ mobile home co-op

My elderly parents inherited a mobile home in a co-op resident owned park in CA. They have allowed me to stay in the home until I get back on my feet job-wise (I'm obviously under the age limit). Both the park manager and residents association leader have seen me leaving the park on several occasions and have said nothing about it, but I'm suspecting they will eventually.

I've read about unauthorized tenant loopholes where if I've been living there in plain-view of the managers for 3 months they have inadvertently accepted my residency in the park and we can't be evicted, is this true for senior co-ops?

For the record I haven't been a nuisance or rowdy, and don't even use the park facilities. I wonder if they put 2 and 2 together that I live here.

I do provide some care and errands for my parents but they're not so bad off that they need a live-in aide.

Any help is much appreciated.
