This is my office. My county allows this but yours may not. They may require a stamp from an architect and something drawn to more detail. Typically, the more urban an area is the more reqs and the more of a pain. The more costly, red tape, etc.
In my small town, the zoning/planning commissioners are friendly and helpful for the most part and I'm kind of friendly with the head of the building department. I have a real estate/construction company on the side so I'm used to working with these folks. I also have properties in NYC. The city operates 180 degrees from the way my small town does.
Anyway, my office is outlined in yellow. I built out everything, about 2200 sq ft in case my practice grew. My practice grew but I ended up subleasing out the remaining space as I prefer real estate as opposed to practicing medicine for the most part. Remember to review the code before drawing something up otherwise you're going to go back and forth a million times.
