Our Work



Benefits
Smart, future-ready charging
We design EV charging systems that scale with your needs: 40–50A circuits sized per Article 625, smart EVSE with Wi‑Fi/Bluetooth, and load-sharing options that add capacity without upgrading your main service. We can integrate with solar and battery systems for surplus-solar charging, and set time-of-use schedules to align with SCE off-peak rates. For multi-car households, we deploy EV energy management systems, CT-based load monitoring, or dual-port chargers that dynamically balance load to protect your panel while maximizing charge speed.
Permits and code expertise
Shaffer Construction manages your permit application, plan set, and inspection. We build to the 2022 California Electrical Code (based on NEC 2020), CALGreen, and local Santa Monica amendments. Our designs follow NEC Articles 110, 220, and 625, with conductor sizing, OCPD selection, and labeling per code. For garage receptacles, we include required GFCI protection; for hardwired EVSE, we follow dedicated circuit and disconnect rules. We coordinate with the City of Santa Monica inspectors to ensure smooth approvals and a clean final sign-off.
Quality you can trust
We use copper THHN/THWN‑2 conductors, Schedule 80 PVC or galvanized steel conduit in exposed areas, NEMA 3R/4X enclosures outdoors, and stainless steel fasteners for coastal durability. Terminations are torqued to manufacturer specs, penetrations are sealed for moisture control, and labels are printed to last. We install surge protection at the service or subpanel and test every circuit for voltage drop, insulation resistance, and GFCI function where required—delivering a robust, reliable installation that stands up to salt air and daily use.
Customized planning and design
Every home is different. We begin with a detailed load calculation, panel assessment, and cable path survey—from your main service to the parking spot you actually use. We confirm charger brand preferences (Tesla, ChargePoint, Wallbox, Emporia, Enphase) and match them to your driving habits and utility rate plan. If your garage is detached off an alley or part of a shared condo structure, we design the route, specify trenching or overhead options, and create a plan set tailored to the building while minimizing invasiveness and visual impact.
What We Offer
Frequently Asked Questions
How much does it cost to install a residential EV charger at my Santa Monica home?+
Level 2 home chargers cost $500-1,500 for equipment, plus $1,000-3,000 for installation (shorter runs cost less, longer runs cost more). Total installed cost is typically $1,500-4,500. Installation complexity depends on distance from panel to charger location and whether panel upgrade is needed. Permits add $300-700. Many utilities and the state offer rebates offsetting 20-40% of costs. Charging at home costs $0.10-0.20 per kWh, versus $0.30-0.50 at public stations. Most Santa Monica EV owners save $1,000+ annually through home charging.
What size electrical service do I need for EV charging at home?+
Most Level 2 chargers use 30-40 amps, requiring a 40-60A dedicated circuit. If your home has 100A service and heavy loads (air conditioning, electric heating), adding EV charging may require a 200A service upgrade. We assess your actual usage pattern and recommend the most cost-effective solution. For Santa Monica homes planning solar or heat pump water heaters, we design panel upgrades to handle everything. Oversizing slightly during upgrades (e.g., from 100A to 200A) costs $3,000-5,000 more but prevents future bottlenecks and supports your electrification goals.
Can I charge during off-peak hours to save money on my Santa Monica electricity bill?+
Yes. Time-of-use (TOU) rates offer lower electricity prices during off-peak hours (typically 9 PM-6 AM). Programming your EV charger to charge during these hours saves 30-50% compared to peak rates. Smart chargers with TOU compatibility are standard. Some utilities offer special EV rates even cheaper than general TOU. We help you understand your utility's rate structure and program the charger accordingly. For Santa Monica residents on solar, you can charge during daylight (free solar power) or schedule charging for off-peak utility hours. Smart charging is essential to maximizing EV savings.
How do I choose between installing an EV charger in my garage versus outdoors?+
Garage installation is ideal: protected from elements, easy access, and less visible. Outdoor installation requires marine-grade, weatherproof equipment rated for coastal salt air. Outdoor chargers cost 20-30% more due to robust materials. Cable management and conduit routing are easier indoors. For Santa Monica homes without garage space, outdoor installation is a viable option with proper equipment selection. We assess your home layout and recommend the best location. Whichever location you choose, proper installation with sealed connections and corrosion-resistant materials ensures long-term reliability.
What happens if my Santa Monica home doesn't have sufficient electrical service for EV charging?+
A service upgrade is needed. Going from 100A to 200A service costs $3,000-5,000 and takes 1-2 days. SCE (Southern California Edison) may need to coordinate if meter or transformer changes are needed. Permits take 1-2 weeks. We handle permits and coordinate with SCE. While a service upgrade is significant, it future-proofs your home for EV charging, solar, heat pumps, and other electric loads. Many Santa Monica homeowners bundle this with other electrical upgrades to maximize cost efficiency. Proper service upgrade is safer and cheaper than operating near capacity.
How do I ensure my EV charger is safe and code-compliant in Santa Monica?+
All EV charger installations require electrical permits and City of Santa Monica Building and Safety approval. Code requires proper grounding, circuit breaker sizing, and dedicated circuits. We handle all permits, coordinate inspections, and ensure code compliance. After installation, we test the charger thoroughly and verify proper operation. Your charger comes with UL certification confirming safety. Insurance companies may require permits and inspections for coverage. Professional installation ensures safety, compliance, and warranty protection. Never install a charger without proper permitting—it violates code, voids insurance, and creates liability.
