Title 24 in Climate Zone 3

• Windows: U-factor 0.27 or lower (no SHGC limit in this zone), with total window area up to 20% of floor area.
• Solar PV sized by the CEC formula kW = (floor area x 0.628) / 1000 + 1.12; no PV is required if that is under 1.8 kWdc, which for a single ADU works out to about 1,083 sq ft or smaller.

HVAC design for Albany

The California Energy Commission's design-day data for Albany gives the outdoor conditions a Manual J load calculation uses: a summer design temperature of 81°F and a winter design temperature of 30°F.

Summer design (1%)	81°F dry bulb / 64°F wet bulb
Winter design (median of extremes)	30°F
Daily temperature range	16°F
Elevation	40 ft

Loads are small in this mild climate, so the common mistake is oversizing. A right-sized heat pump runs longer, quieter cycles and controls humidity better than a rule-of-thumb unit.

Electrical service from Pacific Gas and Electric (PG&E)

If the load calculation shows you need a service upgrade, a second meter or a relocated service, Pacific Gas and Electric (PG&E) handles that through its Your Projects portal, separately from the building permit.

Plumbing and sewer

The plumbing plan shows the route, slope and cleanouts of the connection to the existing sewer lateral. Some Bay Area cities also have private sewer lateral inspection rules, so ask whether your project triggers one.
