Expert ADU Construction in Newport Beach, California

Expanding your property's footprint in Newport Beach requires more than just a general contractor. From navigating local coastal ordinances to optimizing space on tightly zoned lots, Accessory Dwelling Unit (ADU) development demands a precise, coordinated approach. STG Design Build delivers exactly that. We are a licensed, bonded, and insured Southern California design-build firm specializing in high-quality residential architecture and construction.

A Unified Design-Build Approach

Building an ADU involves multiple moving parts: architectural planning, structural and MEP engineering, rigorous city permitting, and final construction. Managing separate contractors and designers often leads to costly delays and communication breakdowns. STG Design Build eliminates this friction by housing every phase under one roof. Our integrated team moves your Newport Beach project efficiently from initial concept and municipal approvals through to final execution.

Proven Track Record in Southern California

Built for the Discerning Property Owner

Our ADU construction services are designed for homeowners and investors who prioritize structural integrity, superior design, and professional project management. We do not cater to projects focused on corner-cutting or lowest-bidder tactics. Instead, we deliver long-term value through meticulous planning and superior craftsmanship, ensuring your new unit seamlessly integrates with your primary residence and meets all local compliance standards.
