From research I did on New Zealand: 14 days isn’t long enough if people are isolating together- live infections get passed to housemates partway through, who are still contagious when the 14 days are up. So either you have to truly isolate everyone, or extend it by some number of days for each additional person.
Also, I assume you mean “14 days, unless they test positive or show symptoms”, but then you have to figure out how to test and verify symptoms for everyone.
