Huntington Beach - ADU Construction

Adding an Accessory Dwelling Unit (ADU) to your property requires meticulous planning, precise engineering, and flawless execution. STG Design Build provides comprehensive ADU construction services for homeowners, property owners, and real estate developers in Huntington Beach. By integrating architecture, structural and MEP engineering, permitting, and construction under one roof, we deliver a seamless design-build experience that eliminates costly delays and miscommunications.

Complete Design-Build Accountability

Traditional construction often fractures responsibility across multiple contractors and designers, leading to budget overruns and timeline conflicts. Our integrated approach ensures you have one accountable team from initial concept through final construction. Led by Founder and CEO Rober Khalil, who brings over a decade of design-build expertise, our firm has successfully completed over 400 projects for more than 100 clients over 7 years in business. We manage every phase of your Huntington Beach ADU project, ensuring strict adherence to quality and safety standards.

Our ADU Construction Process

Architectural Design & Space Planning: We design custom ADUs optimized for your property footprint and investment goals. Structural & MEP Engineering: Our engineering capabilities ensure your ADU is structurally sound and equipped with robust mechanical, electrical, and plumbing systems. Permitting Coordination: We handle the complexities of securing all necessary approvals before ground is broken. Full-Service Construction: Our licensed, bonded, and insured construction team builds your ADU to the highest professional standards.

Who We Serve

Our ADU construction services are built for clients planning significant property investments that require professional architecture, engineering, and full-service construction. We do not take on minor handyman repairs, maintenance-only jobs, or projects selected solely on the lowest price where full design-build coordination is not required. If you need a high-level, coordinated approach to building an ADU in Huntington Beach, our team is equipped to deliver.
