Chula Vista combines the master-plan east (Otay Ranch, EastLake, Rancho del Rey) with the older west around Old Town and Third Avenue.

A straightforward 100A → 200A upgrade in a single-family home runs $2,800 to $4,200 installed, including the permit, new meter socket, main breaker, grounding, and SDG&E coordination.
