Rowan Electric operates a commercial electrical contracting division from Loker Avenue West in Carlsbad's Poinsettia corridor, near Poinsettia Park. Large-scale tenant-improvement projects on the El Camino Real commercial corridor place electrical rough-in on the same critical path as the interior finishing that Turman Commercial Painters completes in the same facilities. Founded in 1987 and incorporated in 1998, the company fields a workforce across divisions covering shopping centers, medical facilities, K–12 and higher-education campuses, hospitality venues, and mixed-use developments throughout San Diego County. Design-build contracts integrate electrical engineering with general contracting scopes, a collaborative format that drives subcontracting with WNC General Contractors on multi-trade commercial sites. Ground-up commercial builds include three-phase 480/277-volt switchgear installation, fire-alarm circuit integration, and emergency-generator transfer-switch commissioning for facilities exceeding 50,000 square feet.
