Title 24 Projects in Rancho Cucamonga
Rancho Cucamonga rises from the valley floor toward the mountains, and its housing changes with the slope. Lower areas are dominated by master-planned neighborhoods of tract homes and apartments built over the last few decades, while the northern foothill areas such as Alta Loma and Etiwanda include older homes on larger lots, custom houses and equestrian-style properties.
Many tract homes have reached the age where the original air conditioner, furnace and water heater need replacing, so equipment changeouts — frequently to a heat pump — are a common reason for a report. Larger foothill lots lend themselves to detached ADUs, casitas and sizeable additions, and custom homes on the upper slopes bring more glass, more complex roofs and views facing south over the valley. In Climate Zone 10, south- and west-facing glass and attic ducts are the items the energy model is most sensitive to.
Foothill properties may also be subject to wildfire-area construction rules under Chapter 7A of the California Building Code; that is a separate requirement from the Title 24 energy report. For backyard units, see ADU Title 24 reports; for how compliance is calculated, see Title 24 calculations.
