CCS Inc — Licensed ADU Builder and General Contractor in Los Angeles
CCS Inc is a licensed general contractor (CSLB #B1047699) that has been serving Los Angeles homeowners since 1984. With over 40 years of experience, they specialize in accessory dwelling unit construction, garage conversions, room additions, remodeling, and city compliance work. As a full-service ADU contractor, they manage every phase of a project in-house — from design and engineering through permitting and final construction.
Whether a homeowner is looking to build a new detached ADU, convert a garage into a legal dwelling unit, or resolve building code violations, CCS Inc offers a free initial consultation to assess the situation and provide honest, straightforward guidance. Their team has deep familiarity with the Los Angeles Department of Building and Safety (LADBS) and navigates the permitting process on behalf of their clients.
ADU Construction Services Offered

- Detached ADU construction — standalone backyard cottage structures up to 1,200 sq ft, complete with full kitchen, bathroom, and all utilities
- Attached ADU construction — additions connected to the main home with a private entrance, kitchen, and bathroom
- Garage conversion contractor services — converting existing garages into fully permitted, legal dwelling units without the need for a new foundation
- Junior ADU (JADU) construction — up to 500 sq ft within the existing home footprint, with an efficiency kitchen and optional shared bathroom

As an experienced granny flat builder and in-law suite builder, CCS Inc helps families create independent living spaces on the same property — ideal for aging parents, adult children, or long-term rental income. Many ADUs in Los Angeles generate between $1,500 and $3,500+ per month in rental income and can add $150,000 to $450,000+ in property value.
Garage conversions are among the most cost-effective ADU options available, typically ranging from $95,000 to $225,000 depending on scope. New detached ADU construction in Los Angeles generally costs between $200,000 and $400,000+, with construction averaging $300–$400 per square foot. Soft costs such as architectural plans, engineering, and permits typically add another $15,000–$45,000.
Permitting, Compliance, and the Build Process
CCS Inc manages the entire permitting process through LADBS, including plan check submissions, fire department review, and all required agency approvals. Under AB 1332, effective January 1, 2025, California cities must offer pre-approved ADU plan programs, allowing permits to be issued in as little as 3–4 weeks. Custom ADU designs typically require 4–6 months from design to approved permit, with total project timelines from start to move-in running approximately 9–18 months for a new detached ADU.
Their process follows a clear, structured approach:
- Free consultation and site visit — zoning, setbacks, and feasibility are assessed at no cost
- Design and engineering — in-house architectural plans, structural engineering, and Title 24 energy calculations
- Permit expediting — full LADBS submission and plan check management
- Construction — foundation, framing, electrical, plumbing, HVAC, drywall, flooring, and finishes
- Inspections and Certificate of Occupancy — all city inspections coordinated through to final sign-off
CCS Inc also assists homeowners who have received an Order to Comply (OTC) or Notice to Comply from LADBS. Failing to respond to these orders can result in daily fines, re-inspection fees, and referral to the City Attorney. Their compliance specialists assess violations and identify the most efficient path to resolution, including retroactive permitting where applicable.
For Los Angeles homeowners considering a backyard cottage, Casita, garage conversion, or any type of accessory dwelling unit, CCS Inc provides a single point of contact from the first consultation through the final inspection — backed by over four decades of experience in the Los Angeles construction market.
