Our Work
Benefits
Future-ready ventilation
We design ventilation wiring that’s ready for today’s needs and tomorrow’s growth. From networked BACnet/Modbus interfaces to demand-controlled ventilation using CO2, humidity, or VOC sensors, we implement scalable control architectures. We deploy VFD-ready power, smart relays, and low-voltage control cabling to integrate with BAS platforms used across Torrance commercial buildings. Where appropriate, we specify ECM fan motors, adaptive timers, and cloud-enabled monitoring to reduce energy costs and simplify maintenance.
Permits and compliance
Shaffer Construction navigates Torrance permitting from start to finish. We build to the California Electrical Code (based on the NEC), California Mechanical Code, and Title 24 Part 6 Energy Code, with CalGreen and NFPA 96 compliance for commercial kitchens. Our packages include single-line diagrams, load calculations, fault current and OCPD coordination as needed, and cut sheets for fans and controls. We coordinate inspections with the City of Torrance Building and Safety Division and, when applicable, Fire Prevention.
Proven quality materials
Our installations use THHN/THWN-2 copper conductors in EMT for interiors, with RMC or rain-tight EMT and compression fittings on rooftops. We specify NEMA 3R or 4X stainless disconnects near fans, plenum-rated MC for ceiling spaces, and gasketed weatherproof enclosures to resist South Bay salt air. We include motor-rated controllers, properly sized OCPDs, and labeled circuits for quick serviceability. Every termination is torque-verified, and we test for insulation resistance and correct rotation before handoff.
Customized design plans
Each project starts with a ventilation needs assessment: occupancy,process, source of contaminants, run time, and noise targets. We right-size fans and circuits, plan routes that avoid sensitive areas, and coordinate with mechanical drawings for duct runs and penetrations. Our design covers controls—timers, humidity/CO2 sensors, interlocks with make-up air—and the exact location of disconnects and penetrations. The result is a clear plan set aligned to your operations, timeline, and budget.
Frequently Asked Questions
Do I need a permit in Torrance for exhaust fan wiring in my restaurant or retail suite?+
Yes. The City of Torrance Building and Safety Division requires an electrical permit for new or modified fan circuits. Kitchen hood systems typically involve coordination with mechanical permits and may require Fire Prevention review for NFPA 96. We prepare and submit all documents, track plan check comments, and schedule inspections to keep your project moving.
How long does the process take from approval to final inspection?+
Permit approval in Torrance typically takes 1–3 weeks depending on scope and plan check volume. Once permitted, most single-fan installations are completed in a half day to one day, with inspection the next available business day. Multi-fan or complex control projects may be phased, and we offer after-hours work to minimize disruption.
Can you work after hours at Del Amo Fashion Center or similar centers to avoid downtime?+
Absolutely. We routinely coordinate with property managers at shopping centers and business parks for off-hours work. We’ll align with building rules, arrange rooftop access, and stage materials so wiring and tie-ins are completed overnight or early morning, keeping your storefront or suite operating during business hours.
Do you coordinate with my mechanical contractor and hood supplier?+
Yes. We review mechanical submittals, confirm fan motor data, establish interlocks for make-up air, and set control points for timers, sensors, or BAS tie-ins. For kitchen hoods, we wire the required interlocks and coordinate with the hood/fire suppression vendor to ensure NFPA 96 compliance and a smooth combined inspection.
