FAQ
Which permits and approvals should I plan for with a JADU project in Los Angeles?
A JADU project in Encino or Los Angeles is about creating a junior accessory dwelling inside the primary residence—with City of LA / local AHJ filings—distinct from a detached backyard ADU or legalizing an already-built unpermitted unit.
Direct answer
Plan interior junior-unit drawings, then AHJ desks.
JADU permits in Los Angeles usually cover floor plans for a junior unit within the primary dwelling, life-safety and utility coordination, and City of LA / local AHJ plan check—not a detached ADU building permit path alone.
This is not a detached ADU FAQ, not legalizing an unpermitted ADU, and not a full second dwelling outside the primary structure. City of LA / local AHJ decides. Not legal advice.
121 Design Build scopes JADU approvals without inventing fee schedules.
JADU permit stack
Interior layout, utilities, then City desks.
Junior unit within the primary dwelling
JADU scope stays inside the main house envelope—not a separate backyard cottage.
Life-safety and utility coordination
Egress, smoke/CO, and shared-system rules often shape the JADU package before filing.
City of LA / local AHJ plan check
JADU work does not skip AHJ review. Queues and comments are owned by the City; we do not invent fees.
Encino context
Encino JADUs still follow City desks inside the primary home.
Working from Encino does not shortcut junior-unit rules. Documents support clearance; the AHJ owns decisions.
Use detached ADU or legalize-unpermitted-adu pages when the question is a separate structure or existing unpermitted unit—not an interior JADU.
