I agree with Cindi. When I worked on new condo developments here in the Bay Area, they also had similar requirements--the occupancy requirement is actually due to the bank's and condo insurance guidelines, generally they required at least 70% owner occupied units with a maximum of 30% investments. The reasoning behind this is 1) Investments tend to be less cared for than homes, and 2) If in the future the development is mostly investors, future buyers' abilities to buy will be hindered since lenders do not like to lend to developments mostly occupied by investment units.
In your particular situation, the developer may give you an exception because you have already purchased your condominium, especially during these times when new developments are having difficulty selling their units. Your situation is not intentional and the developer will most likely allow you to rent out the unit, at least temporarily. It is near impossible for the entire complex to be owner occupied for all time--which is what I interpret the condo laws to say according to your post. That would mean that whenever an owner wants to upgrade to a home or a larger condo/townhouse, they would have to sell their current condo no matter what, which I find to be highly improbable rule to apply to everyone. However, the rules and regulations stated by the condominium association are still enact and enforceable whether or not it is under the developer's control or under the property management company's control. So it is essential to speak to the developer to find out what you can do to prevent any future trouble for yourself. Best of luck Gary!
