Los Angeles - Detached ADU conversion - 150 sq ft expansion for ingress/egress?
I'm looking into converting a detached garage on my property into an ADU. I see on LA County guidelines and CA HCD guidelines that, when converting a detached accessory structure into an ADU, the structure can be expanded by up to 150 sq ft in order to accommodate ingress/egress.
Does anyone have experience with using the 150 sq feet rule? I'm wondering what am I allowed to do with the 150 square feet besides ingress/egress.
For example: Can I add 150 square feet to the structure, including an exterior door, and then use the extra 150 square feet for a kitchenette? Or is it restricted entirely to ingress/egress, i.e., I add 150 square feet and put in an exterior door, but I can't use the 150 square feet for kitchenette, laundry, etc.?
