High-Efficiency Homes,
Built for Southern California.
We engineer custom homes to a measurable performance standard — tighter, healthier, and more durable than anything you’ll find on a tract lot. Every home we build gets blower-door tested, balanced mechanically ventilated, and detailed like we’re going to live in it.

Three things every Jacinto Built home gets right.
Built To Measure
Every home blower-door tested before drywall and at final. ACH50 1.5–2.0 — three to ten times tighter than a typical custom build.
Built To Breathe
Balanced HRV/ERV with MERV 13+ filtration delivers continuously clean air to every bedroom. Wildfire-smoke-ready.
Built To Last
Continuous exterior insulation, smart vapor management, and detailed flashing. Effective R-values that match the spec sheet.
Our standard, side-by-side with the rest.
We publish the targets we build to. No marketing fog — just numbers you can compare to any other builder in the county.
| Metric | Tract Home | Title 24 Code | Jacinto Built | Passive House |
|---|---|---|---|---|
| Airtightness (ACH50) | 5 – 15 | 3.0 – 5.0 | 1.5 – 2.0 | 0.6 |
| Effective Wall R-Value | R-10 – R-13 | R-19 cavity | R-28 – R-35 effective | R-40+ |
| Window U-Factor | 0.30 – 0.40 | 0.30 | 0.20 – 0.25 | ≤ 0.14 |
| Mechanical Ventilation | Bath fans only | Bath fans + exhaust | Balanced HRV/ERV, MERV 13+ | Balanced HRV/ERV, MERV 13+ |
Four phases. Every project. No shortcuts.
Design
Manual J load calc, envelope spec, and full mechanical layout.
Envelope
Continuous insulation and air barrier built before mechanicals.
Test
Pre-drywall blower door verifies the build. Leaks fixed now.
Deliver
Final commissioning and a documented handoff package.
Your whole project. In your pocket.
Every home we build comes with the ProjectFlew dashboard — daily photos, the live schedule, selections, change orders, and invoices, all on your phone. Included with every Jacinto Built project.
The people who build your home.
