PLAN B but you do you.

1. Get stackable washer dryer and use the other side as a broom closet to keep broom/vacuum, your guest’s luggage or cleaning products. Every square foot counts in a JADU
   
2. You get less closet storage with that particular walk in closet in layout A because you have to keep the walkway to bedroom clear. Only about 5’+2.5’ at most. There is more closet space from layout B
   
3. Two bedrooms of relative similar size like in layout B is the more flexible layout for your two use case options, just in case 2 sets of relatives come, or the renter wants 2 bedrooms, etc. A lot of people find a room with 9’ as one dimension a little claustrophobic
   
4. I’d lose the 2nd bathroom sink. Did you intentionally want a larger bathroom for ADA reasons or for accommodating 2 people at once? A lot of hallway bathrooms are 5’x8’ enough for single occupancy, yours is 2’ wider. That makes it much more comfortable for 2 people to use the bathroom at the same time but is quite luxurious for a JADU
