Puentes Electric in Chula Vista focuses on high-end residential electrical work, including panel upgrades, full-home rewiring, and custom lighting design, from its Montcalm Street base in the 91911 zip code. New ADU and garage-conversion projects — a growing segment that involves design firms such as ADUs & Garage Conversions | Sprawl Design — require dedicated sub-panels and load calculations under California's updated ADU building codes. The company also installs Level 2 EV charger circuits rated for 240 volts and up to 60 amps, meeting the demand created by Chula Vista's rising electric-vehicle adoption. Outdoor landscape-lighting projects in Eastlake and Otay Ranch developments frequently coordinate with hardscape contractors at Alpha Turf Inc, where low-voltage LED path lights and uplights are trenched alongside synthetic turf borders. The firm's most complex residential installations include whole-home Lutron or Leviton smart-lighting systems wired through a centralized dimming panel with scene-programmable keypads across multiple zones.
