I recall you mentioning that previously.
Did the builder do the changes or were these after the fact?
After the fact.
1. Did you have to get city approval/permits for this change?
Yes, we had to get city approval before the project began, an inspection after new plumbing was installed, another after drywall was installed, and a final inspection/sign off when complete.
2. Was it costly? It seems like it would be expensive to pull a gas line to the front powder (on top of the plumbing/drain work for the rear bath).
I believe I got a great deal actually. For the entire conversion, minus the shower and vanity, was $20K.
3. What did you mean "could not do additions"? I presume you mean by your choice and not something that was disallowed by the HOA and city (although I wouldn't flinch at that notion... some neighbor contending that you are blocking their "view" by adding a structure above your garage).
Yes, it was my choice, especially when factoring in the price it would cost. Plus nothing can be added on the second floor without drastically changing the floorplan like you did above, which would make it too costly. Oh, and what view?
