Cornerstone Communities is a La Jolla, California‑based homebuilder focused on creating new‑home neighborhoods in Southern California, with active offerings across San Diego County. Its leadership team aggregates more than 150 years of combined development and construction experience and has been responsible for more than 15,000 homes across more than 60 California and Nevada communities. The firm has earned industry recognition, including a designation as a Building Giants by Professional Builder and repeated rankings among San Diego’s top privately held residential builders.

The company serves entry‑level homebuyers seeking new residences in the San Diego region, with plans for Candlelight to comprise 450 all‑electric townhomes. In March 2023, Cornerstone expanded its land holdings with a 44‑acre acquisition in Otay Mesa to support that project. The business has a history of pursuing additional Otay Ranch‑area parcels for master‑planned developments, reflecting a focus on growth within San Diego County.
