EV Charger Installation Guide | Shaffer Construction, Inc.

Introduction

Electric vehicle adoption continues to accelerate across the United States, and Los Angeles stands at the forefront of this green energy revolution. Whether you're a residential homeowner looking to install a personal EV charging station or a business owner planning commercial charging infrastructure, understanding the complete landscape of EV charger installation is essential. Shaffer Construction, Inc. brings over two decades of electrical expertise to guide Los Angeles property owners through every step of the EV charger installation process, from initial assessment to final activation.

Understanding EV Charger Types and Technologies

The EV charging ecosystem consists of three primary charging levels, each serving different needs and timelines. Shaffer Construction specializes in all three types, ensuring you select the right solution for your specific application.

Level 1 chargers are the most basic option, using a standard household outlet and delivering approximately 2-3 miles of range per hour. While this option requires no special installation, it suits only residential situations where charging overnight is acceptable. Level 2 chargers are the most common choice for both residential and commercial applications, delivering 25-30 miles of range per hour and requiring 240-volt electrical service. These chargers are ideal for homes, apartments, and workplaces where vehicles can charge for several hours.

DC fast chargers represent the cutting edge of charging technology, delivering 150-350 miles of range in just 20-30 minutes. These systems require specialized three-phase electrical infrastructure and significant electrical capacity, making them the domain of commercial corridors and public charging networks. Los Angeles property owners increasingly recognize that having adequate charging infrastructure boosts property values and attracts tenants or customers. Shaffer Construction has installed hundreds of Level 2 and DC fast charging systems across Los Angeles, understanding the unique electrical demands of each type.

Key Benefits of Installing EV Charging Infrastructure

Installing EV chargers offers tangible benefits that extend far beyond convenience. For residential property owners, home charging eliminates daily trips to gas stations while providing the most affordable charging option—roughly one-quarter the cost per mile compared to gasoline. This translates to significant annual savings for households committing to electric vehicles.

Commercial property owners and developers gain competitive advantages by installing EV charging. Forward-thinking businesses in Los Angeles recognize that employees, customers, and residents increasingly expect charging availability. As detailed in our comprehensive article on preparing Los Angeles buildings for the EV charging boom, properties with charging infrastructure attract higher quality tenants and command premium rental rates.

From an environmental perspective, every mile traveled in an electric vehicle powered by California's increasingly renewable grid eliminates emissions that would otherwise contribute to Los Angeles's air quality challenges. The city's history with smog and ongoing air quality concerns make this environmental benefit particularly relevant to local property owners. Additionally, federal and state tax credits and incentives can offset a significant portion of installation costs, particularly for commercial installations and multi-unit residential properties.

Shaffer Construction helps Los Angeles property owners navigate these incentive programs, ensuring you maximize available rebates and tax credits as part of your installation project.

Critical Electrical Requirements and Load Studies

Understanding your property's electrical capacity is fundamental to successful EV charger installation. This is where many property owners make costly mistakes—attempting to install charging systems without proper assessment. Shaffer Construction always begins with a thorough electrical load study, a critical process that evaluates your existing electrical panel capacity, overall power consumption patterns, and the feasibility of adding EV charging loads.

A Level 2 charger typically requires a dedicated 40-50 amp circuit and 240-volt service. For residential installations, this often means upgrading from a 100-amp to a 200-amp service panel—a substantial but necessary investment. Commercial properties installing multiple Level 2 chargers or a single DC fast charger face even more complex calculations, potentially requiring three-phase power upgrades or even transformer replacements.

As discussed in our article on how to decide, pay for, and plan your EV charger project, electrical load studies are non-negotiable. They protect your investment and ensure safe, compliant installation. Shaffer Construction's electrical engineers conduct detailed load analyses, identifying whether your existing infrastructure can support charging or if upgrades are necessary. These studies often reveal opportunities to optimize your entire electrical system while installing charging, potentially saving money on overall electrical upgrades.

Installation Considerations and Permit Requirements

EV charger installation in Los Angeles involves navigating a complex permit and compliance landscape. The California Title 24 energy code, Los Angeles City electrical codes, and various permitting requirements create a regulatory framework that experienced contractors understand intimately. Shaffer Construction manages the entire permitting process, ensuring your installation meets all applicable codes and regulations.

Site selection is equally critical. For residential installations, chargers should be positioned for convenient access while minimizing cable runs across walkways and high-traffic areas. Commercial properties require more sophisticated planning—strategically placing multiple chargers to serve the highest-traffic areas while managing electrical distribution efficiently. Weather protection, ground conditions, and future expansion potential all factor into site selection decisions.

The installation itself involves coordinating electrical work, concrete work for pad-mounted systems, conduit routing, and final inspections. Our team at Shaffer Construction oversees every detail, coordinating with inspectors and managing project timelines to minimize disruption to your operations. For residential properties, installations typically complete within 2-5 days. Commercial projects are more variable depending on scope, but Shaffer Construction's experience ensures efficient, professional execution that minimizes business interruption.

Cost Analysis and Financial Planning

EV charger installation costs vary significantly based on charger type, electrical infrastructure upgrades, and site-specific conditions. Residential Level 2 charger installations typically range from $1,000-$2,500 for the equipment itself, with installation costs adding $1,500-$4,000 depending on electrical panel upgrades. Los Angeles properties requiring significant electrical upgrades may face higher costs, but these investments increase property value and qualify for substantial tax credits.

The federal Inflation Reduction Act offers a 30% tax credit (up to $1,000) for residential Level 2 charger installation. California provides additional rebates through various programs, and some Los Angeles municipalities offer local incentives. Shaffer Construction helps you identify and apply for these programs, effectively reducing your net installation cost significantly.

Commercial installation costs are more complex, ranging from $3,000-$15,000+ per charging spot depending on electrical infrastructure needs. However, commercial properties enjoy substantial benefits—workplace charging drives employee satisfaction, attracts EV-owning customers, and positions your business as environmentally progressive. Our article on EV charging infrastructure in 2025 provides deeper financial analysis for different property types.
