Hello,
I purchased my first flip last Friday. I bought it as a 4 bedroom 1 bath. The garage had been converted to the fourth bedroom. I had plans to add a bathroom to it and make it the master bedroom with master bath. I called the city and they tell me there was not a permit pulled to convert the garage to a living space. Long story short they tell me I must have 2 parking places. I would have to go through the zoning board to get the permit to convert the garage and most likely they will deny it. Do I build it anyway or come up with a different plan?
Any help would be greatly appreciated.
Jason
