O'Coyne Electric, Inc. in Alpine holds CSLB license #1009321 (C-10 Electrical) and serves commercial and residential clients throughout San Diego County from its Boulders Lane office. The company's commercial scopeâincluding fire-alarm system installation, security lighting, and energy-efficient fixture packagesâpairs with HVAC electrical tie-ins coordinated through contractors like Maximum Comfort Heating and AC Repair on Alpine Blvd. Residential services cover circuit-breaker installation, knob-and-tube wiring replacement, and exterior lighting upgrades for Alpine properties along the Tavern Road and Willows Road corridors near Viejas Casino & Resort. Commercial lighting design extends to retail and office facilities in the Viejas Outlet Center area, where tenant-improvement build-outs require Title 24 compliance documentation. Plumbing rough-ins on new-construction projects coordinate with firms such as Alpine Plumbing & Backhoe Inc on Alpine Blvd, sequencing underground conduit runs before slab pours. Highest-tier installations include NFPA 72-compliant addressable fire-alarm panels with zone-module programming and annunciator integration for multi-tenant commercial structures.
