Irvine - ADU Construction

Integrated ADU Construction in Irvine

Property owners and real estate developers in Irvine face strict requirements and complex coordination when building Accessory Dwelling Units. STG Design Build delivers a full-service, design-build solution to navigate these challenges. We integrate architectural design, structural and MEP engineering, permitting, and construction under one roof. The result is a streamlined process that minimizes delays, prevents design conflicts, and limits costly revisions.

One Accountable Team from Concept to Final Construction

Managing separate architects, engineers, and general contractors often leads to communication breakdowns and budget overruns. We operate differently. As a unified design-build firm, we give our clients a single point of accountability. Led by Founder and CEO Rober Khalil, our integrated team handles every phase of your Irvine ADU project, ensuring the initial design translates flawlessly into the final build.

Our ADU Design-Build Process

With over seven years in business and more than 400 projects completed for over 100 clients across Southern California, we have refined a proven approach to complex residential and multifamily additions. Our comprehensive ADU construction services include:

• Architectural Design: Custom ADU layouts tailored to your property footprint, functional needs, and design aesthetic.
• Structural & MEP Engineering: Fully coordinated mechanical, electrical, plumbing, and structural plans executed alongside the architectural team.
• Permitting Coordination: Efficient navigation of local building codes and municipal approvals to keep your project on schedule.
• Full-Service Construction: Professional site management and ground-up execution by licensed, bonded, and insured builders.

Project Qualification

STG Design Build partners with clients who require professional design, rigorous engineering, and full-service construction management. We serve homeowners, multifamily owners, and commercial developers planning significant structural additions. Please note that we do not take on minor handyman repairs, maintenance-only tasks, or projects driven solely by the lowest bid where professional design and engineering are not required.
