We have ten units in our condo building. We want to limit the number of condo units which can be rented to two. Can we write a change to the condo association bylaws that defines this? Two units were purchased initially to be rentals. There is a third condo owner who wants to rent his unit. How can we enforce the 2/10 rule? We all remember that 80% of condo units have to be owner occupied, but cannot find where we got that idea?
