Title 24 in Climate Zone 10
- Windows: U-factor 0.30 or lower and solar heat gain coefficient (SHGC) 0.23 or lower, with total window area up to 20% of floor area (west-facing up to 5%).
- Whole-house fan required (at least 1.5 cfm per square foot of floor area); units of 500 sq ft or less are exempt.
- Cool roof required: steep-sloped roofs need aged solar reflectance 0.2 or higher and thermal emittance 0.75 or higher.
- Solar PV sized by the CEC formula kW = (floor area x 0.627) / 1000 + 1.41; no PV is required if that is under 1.8 kWdc, which for a single ADU works out to about 622 sq ft or smaller.

HVAC design for Mira Loma
The California Energy Commission's design-day data for Mira Loma gives the outdoor conditions a Manual J load calculation uses: a summer design temperature of 99°F and a winter design temperature of 25°F.
| Summer design (1%) | 99°F dry bulb / 68°F wet bulb |
|---|---|
| Winter design (median of extremes) | 25°F |
| Daily temperature range | 34°F |
| Elevation | 700 ft |
| Heating degree days | 600 |
Both seasons matter here. The heat pump is usually sized for the 99°F cooling condition and then checked to confirm it still covers the heating load at 25°F.
Electrical service from Southern California Edison (SCE)
If the load calculation shows you need a service upgrade, a second meter or a relocated service, Southern California Edison (SCE) handles that through its Building, Renovation, and Project Planning Portal, separately from the building permit.
