San Clemente - ADU Construction

Maximize your property's value and utility with a custom Accessory Dwelling Unit (ADU). STG Design Build provides full-service ADU design and construction in San Clemente, guiding property owners from initial concept through final build. Whether you are a homeowner adding living space for family or a real estate developer executing a new project, our integrated design-build approach ensures a seamless project execution.

The Design-Build Advantage for Your ADU

Building an ADU involves navigating complex zoning laws, securing permits, and coordinating multiple disciplines. Traditional construction models often force property owners to manage separate architects, structural and MEP engineers, and general contractors. STG Design Build brings all these critical functions under one roof. By integrating architecture, engineering, permitting, and construction, we provide one accountable team. This unified workflow significantly reduces delays, prevents design conflicts, and eliminates costly revisions.

Comprehensive ADU Services

Led by Founder & CEO Rober Khalil, our integrated team brings over a decade of design-build experience to your San Clemente property. With over 400 completed projects and 100+ satisfied clients over our 7 years in business, STG Design Build possesses the proven expertise to deliver high-quality ground-up construction. We handle the heavy lifting across every phase:

• Architectural Design: Creating functional, aesthetically pleasing spaces tailored to your property.
• Structural & MEP Engineering: Ensuring rigorous structural integrity and efficient mechanical, electrical, and plumbing systems.
• Permitting: Navigating local municipal codes to secure all necessary approvals without unnecessary delays.
• Construction: Delivering professional, full-service building execution from foundation to final finish.

Who We Serve

We partner with homeowners, property owners, and commercial businesses across San Clemente who require professional, full-service design, engineering, and construction. Our comprehensive methodology is built for significant additions and ground-up ADU projects. Please note that our firm specializes in full lifecycle design-build services; we are not structured for minor repair jobs, maintenance-only requests, or projects selected solely on the lowest price where professional coordination is not required.
