FAQ
Which permits and approvals should I plan for with an SB9 feasibility review in Los Angeles?
An SB9 feasibility study in Los Angeles is not a permit. It is a written map of which permits you will later need — urban lot split, two-unit, ADU or JADU stack, Bureau of Engineering, LADBS — before anyone applies. 121 Design Build in Encino uses that map so owners do not file the wrong stack first.
Direct answer
An SB9 feasibility review is not a permit. It maps the permits you will later need.
SB9 feasibility permits are a planning list, not a counter ticket. Zoning, lot size, existing house, and whether a second unit or ADU can sit with a split all change which agencies you will face. The review names those paths. It does not submit them.
121 Design Build can then sequence the actual filings: lot split, two-unit, ADU stack, BOE, LADBS. That order is the point of the study.
