Lafayette's housing includes custom hillside estates, established upscale neighborhoods, and luxury properties throughout the city.

Lafayette's hillside location creates warm, dry summers-temperatures routinely reach 85-95°F from June through September-while winters are mild and comfortable. The area's elevation and terrain create microclimates with some hillside areas experiencing cooler temperatures than valley locations. This makes versatile heat pumps ideal-delivering efficient cooling during warm weather while providing year-round heating. Many Lafayette homeowners appreciate multi-zone ductless systems for independent temperature control in different areas of their hillside or multi-level homes.
