Frequently Asked Questions About ADU & Commercial Construction

What is the advantage of using an integrated design-build firm for my ADU?
Working with an integrated design-build firm means architecture, structural engineering, MEP engineering, permitting, and construction are handled under one roof. This approach gives you a single point of accountability, reducing delays, conflicts, and costly revisions from the initial concept through final construction.
Do you handle the permitting process for projects in Southern California?
Yes. We manage the entire permitting process across Orange County, Long Beach, and the greater Southern California region. Our internal team coordinates all architectural and engineering plans directly with local municipalities to secure the necessary approvals efficiently.
What types of projects does STG Design Build accept?
We focus on significant developments requiring professional design, engineering, and full-service construction. This includes ADU construction, commercial construction, tenant improvements, ground-up builds, and comprehensive home additions or remodeling. We do not accept small handyman repairs, maintenance-only jobs, or projects selected solely on the lowest price.
What is your team's experience level in the design and construction industry?
Led by Founder and CEO Rober Khalil, who brings over a decade of design-build experience, our firm has successfully completed over 400 projects. Over our seven years in business, we have partnered with more than 100 clients to deliver high-quality results. We are fully licensed, bonded, and insured.
How do I begin planning my ADU or commercial construction project?
The first step is scheduling a discovery call. During this conversation, we evaluate your project scope, discuss your property objectives, and outline how our unified architecture, engineering, and construction services will efficiently execute your build.
