FAQ
Which permits and approvals should I plan for with an ADU project in Los Angeles with a contractor?
ADU projects with a contractor in Encino or Los Angeles are about plan check, construction permits, and AHJ inspections sequenced with a GC crew - distinct from early feasibility or design-build-only framing.
Direct answer
Plan for plan check, construction permits, and GC-side inspections.
An ADU project with a contractor in Los Angeles usually needs a complete plan set for City of LA / local AHJ plan check, construction permits, and inspection rounds while a general contractor crew builds.
This is not an early feasibility lot study alone, not a design-build-only conversation, and not a blank fee schedule. City of LA / local AHJ decides. Not legal advice.
121 Design Build maps ADU contractor approvals without inventing fee schedules.
Permit drivers
Plan check, construction permits, then GC inspection sequencing.
Complete plan package for filing
Architectural, structural, and MEP sheets ready for desk review drive what the City can accept before a contractor builds.
City of LA / local AHJ construction permits
Permit issue and queues are owned by the City. We do not invent fees or legal outcomes.
GC crew inspection rounds
Inspections continue through foundation, framing, and finish under the contractor - still AHJ-owned.
Encino context
Encino contractor ADU filings still answer to City desks.
Working from Encino does not skip plan check or inspections. Documents still answer to City of LA / local AHJ when a contractor builds the ADU.
Use ADU builder permit pages when the real question is design-build team approvals - not GC-crew construction permits.
