Residential Backup Generator Installation in Santa Monica
Shaffer Construction, Inc. delivers safe, quiet, and code-compliant backup power you can trust—integrated with solar, EV chargers, and smart home systems. Whether you live near Palisades Park or the Third Street Promenade, we make the process smooth, from load calculations to final inspection.
Future-ready power
We design for the way you live today—and tomorrow. Our systems leverage smart automatic transfer switches, load-shedding modules for EV chargers and pool equipment, and Wi‑Fi monitoring for health and exercise schedules. For solar-equipped homes, we integrate with Enphase, SolarEdge, and Tesla Gateway equipment to ensure safe anti-islanding and coordinated operation. Scalable designs let you start with critical circuits and expand toward whole-home coverage as needs evolve.
Permits and compliance
We handle the entire permitting process and build to the 2022 California Electrical Code (based on NEC 2020), California Plumbing Code (for gas piping), manufacturer specs, and UL 1008 transfer switch standards. We also address Santa Monica Municipal Code noise requirements and manufacturer-mandated clearances. Documentation includes load calculations (NEC 220), site plans, gas sizing, and anchorage details. Our team coordinates inspections to keep your project on schedule and fully compliant.
Quality you can trust
We specify aluminum or composite enclosures, stainless fasteners, epoxy-coated anchors, Schedule 80 PVC or PVC‑coated rigid steel in exposed coastal areas, and liquidtight fittings for durability. We install whole-home surge protection, perform torque verification, and test insulation integrity. Gas lines are sized for pressure and demand with proper regulators and seismic strapping where required. The result is a quiet, reliable system that stands up to salt air and years of service.
What We Offer
Frequently Asked Questions
Will a complete electrical rewiring shut down my Santa Monica business, or can the work be done in phases?+
We understand minimizing disruption is critical for Santa Monica businesses. Complete electrical rewiring can often be scheduled in phases, working during off-hours, weekends, or section by section to keep your operations running. During our initial assessment, we'll develop a customized timeline that balances thoroughness with your business continuity needs. Our team is experienced in coordinating complex projects around your schedule.
What size backup generator do I need for my Santa Monica home?+
Generator sizing depends on which circuits you want to power. Critical-only systems (refrigerator, HVAC, lights, water heater) typically need 7-15 kW. Whole-home backup (all circuits) requires 20-40 kW depending on home size and loads. A 2,000 sq ft home near Palisades Park might need 15-20 kW; a larger home near Montana Avenue might need 25-35 kW. We conduct a load analysis identifying your essential loads, then recommend appropriate size. Oversizing wastes fuel and money; undersizing leaves you underpowered during emergencies. The right size balances your needs, budget, and space constraints.
My Santa Monica commercial building is older, does that affect the rewiring process or cost?+
Older commercial buildings in Santa Monica often require extra attention due to outdated wiring standards, asbestos-wrapped wiring, or structural considerations. Our electricians are experienced with both historic and modern properties. We'll conduct a thorough inspection to identify any age-related challenges, ensure compliance with current codes, and provide an accurate estimate that accounts for your building's unique characteristics.
Can I integrate my backup generator with solar panels and EV charging?+
Yes. Smart integration is ideal for Santa Monica homes with solar. Your generator backs up critical loads when grid is down. If you have a Tesla Powerwall or other battery storage, the system coordinates charging from solar, battery, or generator depending on time of day and availability. EV chargers can be load-shed (deprioritized) when running on generator to conserve fuel. We design automatic transfer switches and load management systems that handle these priorities seamlessly. For homes with solar near the coast, a backup generator with smart battery integration provides energy independence and resilience.
How do I know if my Santa Monica commercial property needs complete rewiring versus a simple upgrade?+
Complete rewiring is typically necessary when your building has outdated wiring systems, frequently trips breakers, shows signs of electrical wear, or can't support modern business equipment and technology demands. During our free assessment in Santa Monica, we'll evaluate your current system's capacity, age, and condition, then recommend whether a full rewire or targeted upgrades best serve your needs and budget.
How does Santa Monica's electrical code affect residential generator installation?+
California Electrical Code and Santa Monica Building and Safety requirements apply. The main challenge is permit coordination: you need electrical permits, gas permits (if natural gas), and sometimes fire department approval. Your generator must be properly grounded, bonded, and sized per code. Automatic transfer switches must prevent back-feed (generator power flowing to the utility grid). We handle all permits, coordinate inspections, and ensure code compliance. Typical permit timeline is 2-3 weeks. Once permitted, installation takes 1-3 days depending on fuel source and placement.
Will complete electrical rewiring affect my business insurance or help with code violations in Santa Monica?+
Yes, professional rewiring can positively impact both areas. Updated, code-compliant electrical systems may qualify you for better insurance rates and eliminate potential liability issues. If you've received code violation notices in Santa Monica, complete rewiring ensures full compliance with current electrical codes. We handle all permit coordination and inspections, providing documentation that satisfies both city requirements and insurance providers.
Should I choose a natural gas, propane, or diesel generator for my Santa Monica home?+
Natural gas is most common for Santa Monica homes with utility gas service (convenient, continuous fuel supply). Propane is flexible, works without utility gas, and stores indefinitely. Diesel is fuel-efficient but noisier and requires more maintenance. For homes on the coast near Palisades Park, propane avoids gas line installation. For properties with large fuel needs, diesel is economical. We help evaluate your utility services, space, and preferences. Natural gas is usually cheapest operationally; propane offers independence; diesel is for high-load or remote situations. Noise and emissions matter in residential areas.
Can rewiring my Santa Monica commercial space accommodate future technology needs and expansion?+
Absolutely. When we rewire your Santa Monica commercial property, we design the electrical system with future growth in mind. This includes installing adequate circuit capacity, strategically placed outlets, and infrastructure that supports emerging technologies like EV charging, advanced HVAC systems, and increased data needs. Proper planning now prevents costly modifications later as your business evolves.
How much does a backup generator installation cost in Santa Monica?+
Costs vary widely: a 10-15 kW natural gas generator with transfer switch and installation typically costs $5,000-10,000. Larger 20-25 kW systems cost $10,000-18,000. Propane systems cost 10-20% more due to tank installation. Smart monitoring, load-shedding modules, and solar integration add $2,000-5,000. Permits add $500-1,500. Santa Monica coastal properties may require corrosion-resistant hardware, adding 10%. Transparent pricing upfront, with no surprises. Many homeowners find peace of mind during outages justifies the investment. With energy independence and backup power, value often exceeds cost.
What if my Santa Monica business has an electrical emergency requiring immediate rewiring?+
If you're facing urgent electrical hazards, code violations with tight deadlines, or system failures affecting your Santa Monica business, contact us immediately at 323-642-8509. We prioritize emergency situations and can mobilize quickly to assess the problem, implement temporary safety measures if needed, and fast-track your complete rewiring project. Safety always comes first, and we'll work diligently to restore safe, reliable power to your business.
How long does backup power installation take, and will it disrupt my Santa Monica home?+
Installation typically takes 1-3 days depending on fuel source and distance to electrical panel. Natural gas line routing might take additional days if gas service needs extension. We coordinate carefully to minimize disruption: setting the generator outside away from neighbors, running conduit neatly, testing thoroughly before handoff. Once installed and permitted, your generator operates silently until needed. Modern units are quiet (65-75 dB) so neighbors are barely disturbed. For Santa Monica homes, we respect landscaping and view considerations during placement. Your backup power system is ready for the next outage, providing comfort and security.
