Sometimes units are allowed because they are "grandfathered" into the code (built before the law made illegal), but this is going to be a local issue, and probably not something you can get a definative answer about in an online forum like this.If you're worried about insurance disallowing, why don't you call and ask a couple companies for a quote - if you explain the details, they should be able to tell you if it is not insurable.
