Why EV Charging Permitting Expertise Matters

Successfully installing EV charging infrastructure requires navigating:

National Electrical Code (NEC) requirements
- Article 625 EVSE-specific installation requirements
- Load calculation methodologies and service sizing
- Branch circuit and feeder requirements
- GFCI protection and disconnect requirements
Local building & fire codes
- Municipal building code amendments and local ordinances
- Fire marshal requirements for clearances and access
- Structural requirements for mounting and anchoring
- Weather protection and outdoor installation standards
Utility interconnection standards
- Utility-specific application procedures and forms
- Service upgrade requirements and meter configurations
- Load management and demand response capabilities
- Time-of-use metering and billing configurations
Accessibility & zoning requirements
- ADA compliance for parking and charger access
- Van-accessible space requirements
- Signage and marking requirements
- Zoning ordinance compliance for commercial properties
Safety & listing requirements
- Equipment listing and labeling (UL, ETL certified)
- Proper equipment ratings and environmental suitability
- Emergency disconnect and shut-off requirements
- Electrical safety and arc flash protection

Even a minor technical oversight—incorrect breaker sizing, missing equipment labels, improper load diversity calculation—can delay your project by weeks or require expensive field modifications. Our permit-ready designs eliminate these risks completely.

Fast Approvals, Zero Headaches

The difference between smooth permit approval and costly rejection often comes down to critical details—accurate wire sizing, correct equipment labeling, precise load calculations, and jurisdiction-specific technical requirements.

Our team has successfully navigated hundreds of different AHJs across all 50 states. We understand which jurisdictions require structural calculations for wall-mounted chargers, which utilities need specific interconnection application forms, and which building departments expect conduit schedules formatted in particular ways.

This deep jurisdictional experience translates directly into:
- Fewer plan revisions and dramatically faster approval timelines
- Reduced project holding costs and installation delays
- Eliminated re-design fees from plan corrections and code issues
- Confident installations backed by clear, accurate construction documents
