San Clemente ADU Construction

Adding an Accessory Dwelling Unit to your San Clemente property requires more than just a builder; it demands a unified approach to design, engineering, and execution. STG Design Build is a licensed, bonded, and insured Southern California design-build firm that integrates architecture, structural and MEP engineering, permitting, and construction into a single, coordinated process.

Navigating Coastal Regulations and Topography

Developing property in San Clemente presents distinct regulatory and structural challenges. From strict coastal zone overlays and hillside grading requirements to maintaining the architectural integrity expected in the "Spanish Village by the Sea," successful ADU development requires deep technical expertise. We manage these local municipal requirements directly, moving your project efficiently from initial concept and city approvals through to final construction.

A Single, Coordinated Team

Fragmented project delivery causes delays, budget overruns, and miscommunication. We eliminate the friction of managing separate architects, engineers, and contractors. Our integrated team ensures that the design approved by the city is the exact structure we build. With 7 years in business, over 520 clients served, and more than 400 completed projects, we rely on technical precision and transparent project management to execute flawlessly.

Built for Quality and Compliance

We serve property owners who demand high-quality execution and comprehensive oversight. Our services are tailored for clients who value responsive communication and professional accountability over cut-rate compromises. Whether you are building an ADU for rental income, extended family, or property value optimization, we deliver structures that meet rigorous engineering standards.
