Garage as second rental on property

[Matthew Paul]

I have a small building on a property thats already a rental . It has a full bath, and seperate meter  . It is small 22 by 22 ft . I want to do something different . I am going to renovate it as a studio for artists.  Basically it will have the full bath room , a refrigerator , a counter with a sink and cabinets ,and outlet for a kiln ( that outlet could also be used for an oven)  The rest of the building would be open.  Here is the problem , if I put in a closet and oven , it is considered a house , with those it is studio , a place to do things .  Now I wont be able to stop anyone from staying the night . But I will have in my lease it is not a residence .  How do you think this will fly ?
