ADU Contractors in Los Angeles
& the San Fernando Valley
Green Tech Remodeling & Design INC builds detached ADUs, garage conversions, attached ADUs, and JADUs throughout Los Angeles County. We handle design, LADBS permitting, and construction under one contract.
Types of ADUs We Build in Los Angeles County
Every property is different. We build all four ADU types recognized under California law and the LA County ADU ordinance.
Detached ADUs
Standalone backyard structures from 400–1,200 sq ft. Maximum rental income potential and the most flexible design options.
Typical range: $200,000–$500,000+
Garage Conversions
Convert an attached or detached garage into a fully permitted living unit. Most cost-effective option — foundation and shell already exist.
Typical range: $80,000–$150,000
Attached ADUs
An addition to the primary residence with its own entrance, kitchen, and bathroom. Ideal when backyard space is limited.
Typical range: $150,000–$250,000
Junior ADUs (JADUs)
Up to 500 sq ft within the existing home footprint. Fastest permitting path and lowest cost entry point.
Typical range: $60,000–$120,000
Cost ranges are planning estimates for Los Angeles County in 2026. Final pricing depends on site conditions, design scope, permit fees, and finish selections.
Why Local LADBS Experience Matters
ADU permitting in Los Angeles County is more complex than anywhere else in California. Working with a contractor who knows the LADBS plan check process — and has pulled permits in your specific city — saves months of delays.
Our ADU Construction Process
Site Evaluation
We visit your property, assess setbacks, utility locations, soil conditions, and access constraints.
Design & Engineering
Our team produces permit-ready drawings that meet LADBS requirements and your design goals.
Permit Submission
We submit directly to LADBS and manage the plan check process — no third-party expediter.
Construction
Our licensed crews handle all trades: foundation, framing, electrical, plumbing, HVAC, and finish work.
Final Inspection & CO
We coordinate all inspections and deliver a fully permitted, move-in-ready unit.
