@David Edwards I read three sections in combination and drew the conclusion that a detached structure in lot less than 20,000sf can only be used for storage, greenhouse purpose, and in lot larger than 20,000sf they can only be used as Guest Cottage for non-paying occupants.

I had a tenant who moved out and she was burning oily candles all day everyday and all of the walls had a dark waxy coating on them, the carpet was in terrible shape, and her kids drew on the wall everywhere.

Thanks Drew, I agree!
