Our Structured ADU Build Process
We follow a proven four-step process to keep your project running smoothly—from vision to move-in.
1. Consultation & Site Review
We begin by evaluating your property, identifying zoning opportunities and challenges, and discussing what kind of ADU is feasible based on Long Beach regulations and your goals.
2. Design & Permitting
We work with architects and engineers to design a space that fits seamlessly with your existing home—or intentionally stands out. We handle plan submissions, revisions, and all necessary permits to ensure code compliance.
3. Construction
Our veteran-led team oversees the entire construction phase, coordinating trades, managing timelines, and keeping the jobsite safe and clean. You’ll receive regular updates and have direct access to your project manager throughout the build.
4. Final Walkthrough & Completion
Once your ADU is complete, we walk through the space with you to ensure every detail meets our quality standards—and your expectations. We address any final adjustments quickly and professionally.
