Licensed General Contractor · CSLB #1142540
Your Home.
Built A–Z.
ADUs, remodels, and additions — managed from first plan to final inspection. We handle design, permits, and construction so you don't have to chase anyone.
Serving Southern California homeowners and small commercial projects.
What We Build
Residential Services
Every project is planned, permitted, and built by our own crew. No subcontractor lottery. No finger-pointing. One team, one standard.
Turn Unused Space Into Income
Detached garage conversions, new-build ADUs, and junior ADU units. We handle design coordination, city permitting, utility relocation, construction, and final inspection.
Spaces That Work for You
Full gut-and-rebuild or targeted upgrades. Plumbing, electrical, tile, cabinetry, and finish work. Designed for how you actually live, built to last.
More Space Without Moving
Ground-floor additions and second-story extensions. Structural engineering, foundation work, framing, and full finish. We manage the complexity so you don't have to.
Rebuild What You Have
Complete renovations for outdated homes. New layout, systems, finishes. One contract, one schedule, one crew from demo to move-in.
How It Works
From First Call to Final Inspection
No surprises. No disappearing acts. Every project follows the same clear path.
Why Reystone
Not Your Average Contractor
We built Reystone to be the opposite of every contractor horror story. Here's how the "new school" approach works compared to what most homeowners are used to.
| "Old School" Contractor | Reystone "New School" | |
|---|---|---|
| Response Time | Bids take 3+ weeks. Slow follow-up. | Fast quoting. Defined multi-touch follow-up sequence. |
| Reliability | Jobs abandoned. No-shows. | Built by a Marine. Strict adherence to schedule. |
| Professionalism | Poor site assessment. Hidden fees. | Proper assessment. Technology-based project management. |
| Job Site | Messy, unsafe work areas. | Clean, organized, Marine-standard sites. |
| Project Control | You manage the permits and city. | A–Z management: plans, permits, and construction. |

About Reystone
Built by a Marine. Run Like One.
Reystone Construction was founded by Jose Reyes, a Marine Corps Sergeant with a background in federal compliance and supply chain management. That same zero-defect standard applies to every residential project: verify before you build, document before you move on, close out before you leave.
The result is a contractor who doesn't disappear, doesn't cut corners, and doesn't leave you managing the process. One team, one standard, from first plan to final inspection.
