ADU Permits in Los Angeles

ADU Permits Services

Navigating the ADU permitting process in Los Angeles can be one of the most frustrating experiences for homeowners. Between LADBS, LA County, and dozens of independent city building departments, each with their own requirements, timelines, and plan check processes, getting your ADU permitted correctly and efficiently requires deep expertise and established relationships with local agencies.

CCS Inc. provides full-service ADU permit processing - from initial plan preparation through final Certificate of Occupancy. Our permit team has processed hundreds of ADU permits across Los Angeles, Orange, and Ventura counties. We know exactly what each building department expects, how to avoid common rejection triggers, and how to expedite corrections when plan check comments are issued.

Our permit services cover the entire pipeline: preparing code-compliant architectural and engineering plans, completing all application forms, submitting to the appropriate department, managing plan check corrections, scheduling and attending inspections, and obtaining your Certificate of Occupancy. We also handle utility coordination with LADWP, SoCalGas, and local sewer districts, as well as school district and fire department clearances when required.
