Some Of Our Completed Projects

Our ADU Building Process

1. Initial Contact

We like to begin with a short call to learn about your ADU project and see if we can help. If it’s a match, we’ll set up an on-site visit to explore your ideas and discuss your goals in more detail.

2. On-Site Consultation + Rough Project Estimate

During the consultation, we’ll go in detail what your goals are and what ADU options are available with your property size. Afterward, you’ll receive a rough project estimate to give you a clear sense of the potential budget range.

3. Designing & Final Estimate

If you decide to move forward with the design phase, our team will create a detailed plan for your ADU — including layout options, finishes, and materials. Once finalized, we’ll provide a comprehensive proposal and final estimate so you know exactly what to expect.

4. Contract & Permitting

When you’re ready to move forward, we’ll sign the contract and make everything official. We’ll then handle all permits and required paperwork so your ADU is cleared and ready for construction.

5. Scheduling & Planning

Once permits are approved, we finalize your project schedule and order all materials. You’ll receive a clear timeline outlining each phase of your ADU so you always know what to expect.

6. Construction Phase

With all plans and permits in place, our construction team gets to work. We’ll keep you regularly updated so you’re always in the loop and know exactly how your ADU is progressing.

7. Inspections & Quality Checks

Throughout construction, we coordinate all required city or county inspections, ensuring every phase meets code and quality standards. Before completion, our team performs a final quality check review to make sure your ADU is picture-perfect.

8. Project Completion & Final Walkthrough

Once your project is complete, we’ll schedule a final walkthrough to review every detail together. We’ll address any final touch-ups and make sure you’re completely satisfied before closing out permits and officially completing your ADU.
