Electric vehicle charger installations require specialized electrical expertise and strict code compliance. When contractors cut corners, use undersized wiring, skip permits, or fail to follow NEC Article 625, they create fire and shock hazards. This guide helps you document defects and demand proper remediation.

Why EV Charger Defects Are Common
High demand for EV chargers brings unqualified installers
Level 2 chargers draw 30-50 amps requiring heavy wiring
Many homes have older panels with insufficient capacity
Installers skip permits to avoid inspection scrutiny
Rebate programs create rush to complete installations
Demand Letter Objectives
Document specific code violations and safety hazards
Demand complete remediation by licensed contractor
Recover costs of inspections and engineering reports
Seek reimbursement for any vehicle damage
Obtain permit compliance and final inspection approval
Safety First: If you suspect your EV charger was improperly installed, do not use it until a licensed electrician inspects it. Defective installations can cause fires, electrical shock, or damage to your vehicle's charging system.
Legal Framework for EV Charger Defect Claims
California CSLB Licensing Requirements
EV charger installation requires a C-10 Electrical Contractor license in California. The C-10 license authorizes work involving electrical systems over 100 volt-amperes.
Under Business and Professions Code Section 7031, an unlicensed contractor cannot recover payment for work performed and must return all compensation received.
The CSLB can impose administrative penalties, license suspension, and criminal charges for unlicensed contracting.
All electrical work requires permits from the local building department under California Building Code Section 105.1.
National Electrical Code (NEC) Article 625
625.40 Branch Circuit: EV charging equipment must be supplied by a dedicated branch circuit with proper ampacity.
625.41 Overcurrent Protection: Branch circuit overcurrent protection must not exceed the maximum rating marked on the EVSE.
625.42 Rating: Continuous load calculations require wiring and breakers rated at 125% of the charger's maximum current.
625.44 Installation: Equipment must be installed per manufacturer instructions and secured properly.
625.54 GFCI Protection: Outdoor installations and certain indoor locations require ground fault protection.
California Consumer Protection Laws
Statute
Protection
Remedies
Consumer Legal Remedies Act (CLRA)
Prohibits deceptive practices in consumer transactions
Actual damages, punitive damages, attorney fees
Unfair Competition Law (UCL)
Prohibits unlawful, unfair, or fraudulent business practices
Restitution, injunctive relief
Business and Professions Code 7031
Unlicensed contractor cannot enforce contract
Disgorgement of all payments
Civil Code 896 (SB 800)
Construction defect standards for residential work
Repair or damages for code violations
Permit Violations: If the contractor failed to obtain required permits, you may be entitled to rescind the contract entirely and recover all payments. The building department can require removal of unpermitted work.
Documentation Checklist
Contract & Payment Records
Signed installation contract or proposal
Payment receipts, invoices, and credit card statements
Warranty documents for charger and installation
Email and text communications with contractor
Contractor's license number and business information
Permit & Inspection Records
Electrical permit (or evidence none was pulled)
Inspection reports from building department
Failed inspection notices with cited violations
Correction notices and re-inspection results
Certificate of completion (if any)
Technical Documentation
Independent inspection: Hire a licensed electrician or electrical engineer to inspect and document all defects with specific code citations.
Photos and videos: Document the installation including wiring connections, breaker panel, mounting, and any visible defects.
Equipment specifications: Obtain the EV charger's installation manual showing required wire gauge, breaker size, and grounding requirements.
Panel documentation: Photo of electrical panel showing breaker configuration, available capacity, and any modifications made.
Damage Evidence
Vehicle charging records showing errors or failures
Vehicle diagnostic reports indicating charging system damage
Photos of any burn marks, melted components, or scorch damage
Repair estimates from licensed electricians
CSLB License Check: Verify the contractor's license at the California Contractors State License Board website (www.cslb.ca.gov). Document the license status, classification, bond information, and any disciplinary history.
Letter Strategy
Core Legal Arguments
Breach of contract: The contractor failed to perform work in a workmanlike manner and in compliance with applicable codes, which are implied terms in all construction contracts.
Negligence: The contractor owed a duty of care to perform electrical work safely and breached that duty by violating the NEC and local codes.
Licensing violations: If unlicensed or working outside license scope, the contract is voidable and all payments must be returned under B&P Code 7031.
Consumer protection violations: Representing that work would be code-compliant when it was not violates the CLRA and UCL.
Failure to obtain permits: Performing electrical work without required permits violates building codes and contractor licensing laws.
Specific Demands
Immediate remediation: Complete repair of all defects by a properly licensed contractor, at the original contractor's expense.
Permit compliance: Obtain all required permits and pass final inspection from the building department.
Damage compensation: Reimburse for any vehicle damage, property damage, or consequential losses.
Inspection costs: Repay the cost of independent electrical inspections and engineering reports.
Alternative: Full refund: If remediation is not feasible, return all payments and remove the defective installation.
Leverage Points
Threat of CSLB complaint can result in license suspension or revocation
Building department can issue stop work orders and require removal of unpermitted work
Consumer protection claims allow recovery of attorney fees, making litigation viable
Public safety concerns may warrant report to local fire marshal
Documentation of systemic issues can support class action if pattern of defects exists
Statute of Limitations: In California, breach of written contract claims have a 4-year limitation period, while negligence claims must be filed within 2 years. Construction defect claims under SB 800 have specific notice requirements before litigation.

If unlicensed, you may recover all payments under B&P Code 7031. If the contractor is out of business, check if they had a contractor's bond (required for licensed contractors) that may still be valid for claims. You may also have claims against the charger manufacturer if they authorized or recommended the installer.
Yes, you can apply for a permit as the homeowner and request inspection. However, unpermitted work that fails inspection may need to be removed entirely. Some jurisdictions allow "as-built" permits for existing work, but the installation must meet current code requirements. Consult your local building department about their process.
Attorney Services & Contact
EV Charger Defect Representation
I represent homeowners dealing with defective EV charger installations, electrical code violations, and unlicensed contractor work. Cases involving clear code violations and documented safety hazards are strong candidates for full remediation or refund.
Email owner@terms.law or use Calendly for a paid strategy session.
Before filing a demand, verify whether your EV charger installer was properly licensed. Unlicensed contractors face additional penalties and cannot enforce contracts.
California CSLB Lookup
Search the Contractors State License Board database to verify C-10 (Electrical) license status.
EV charger installation requires a C-10 (Electrical) contractor license in California. A general contractor (B license) alone is NOT sufficient for electrical work over $500.
Unlicensed Contractor?
If your installer was unlicensed: (1) They cannot collect payment (B&P 7031), (2) You can recover ALL money paid (B&P 7031(b)), (3) Criminal penalties apply (B&P 7028). This dramatically strengthens your demand.
File a CSLB Complaint
If the contractor was licensed but did defective work, file a complaint with CSLB. They investigate and can revoke or suspend the license, which creates leverage for your demand.
