PERMIT REQUIREMENTS GUIDE
What Do You Need for an EV Charging Station Permit?
A practical checklist of drawings and documents most AHJs require — and how to prepare them.
VIEW CHECKLIST
Securing a permit for electric vehicle supply equipment (EVSE) is a critical step in any commercial or residential installation. The process is governed by the Authority Having Jurisdiction (AHJ) — typically your local building or electrical department — which ensures that the installation meets safety standards and local zoning codes.
Failure to provide a complete and accurate plan set is the leading cause of permit delays. Most AHJs require a specific set of engineering documents that demonstrate electrical load capacity, safety compliance, and physical placement of the equipment. Understanding these requirements — and preparing for them early — is the key to a successful project.
Documents most AHJs require for EV charging permits
Site plan
Showing the location of the charger, parking spaces, and existing structures.
Electrical one-line diagram
Visual map of the electrical system from the service meter to the charger.
Panel schedule
Detailed list of all circuits in the electrical panel, showing new EV loads.
Load calculations
Verification that the existing electrical service can handle the additional demand.
Conduit/wiring details
Specifications for wire gauges, conduit sizes, and raceway types.
Equipment specs
Manufacturer cut sheets and UL/NRTL listing for the EVSE and protection equipment.
General notes (NEC 2023/2020)
Statement of compliance with the relevant National Electrical Code version.
PE-stamped drawings
Drawings reviewed and signed by a licensed Professional Engineer when required.
Accessibility & signage
ADA-compliant stall dimensions, accessible path of travel, and EV charging signage per local code.
Requirements vary by city and county. Always check your specific AHJ’s website for “EVSE Permit Guidelines” before submitting your package to avoid costly revisions. ELDAPRO’s engineers can also communicate directly with your local authority to help ensure your drawings meet specific jurisdictional requirements.
NEC compliance for EV charging permits
The National Electrical Code (NEC) is the foundational standard for safe electrical design. However, different jurisdictions adopt different editions of the code.
Most AHJs currently follow either the 2020 or 2023 NEC cycles. Ensuring your drawings reference the specific year adopted by your city is critical. While the general safety principles remain the same, newer cycles include specific provisions for energy management systems and load-balancing technology that can significantly impact your project design.

How to apply for an EV charging station permit
Follow this 4-step professional workflow to ensure a smooth approval process with your local building department.
Gather info
Identify your AHJ and confirm existing service and panel details, equipment specs, and site measurements.
Prepare drawings
Create your technical plan set using engineering software or an ELDAPRO template.
Submit to AHJ
Upload documents to the city portal and pay required plan review fees.
Respond to comments
Review official feedback and resubmit corrected drawings if necessary.
When is a PE stamp required?
For basic residential installations, many AHJs allow “Simplified Permitting.” However, multi-family, commercial, or high-power industrial installations almost always require a Professional Engineer (PE) stamp.
A PE stamp certifies that the design has been reviewed for safety and code compliance by a licensed professional, reducing liability for the owner and installer.

EV permit requirements — FAQs
What drawings are required for an EV charger permit?
Most AHJs require a site plan, load calculations, panel schedules, a one-line diagram, and equipment specifications, all compliant with the adopted NEC edition. ELDAPRO produces each of these in a single plan set.
Which NEC edition should my drawings follow?
Use the edition your AHJ has adopted — typically NEC 2023 or NEC 2020. ELDAPRO sizes the design to your selected edition and prints the reference in your drawing general notes.
Do I need load calculations for an EV charging station?
Yes — most AHJs require a load calculation to verify that the existing service and panel can support the additional EV circuit, whether for a residential Level 2 charger or a commercial multi-charger site.
Can I generate permit drawings without AutoCAD?
Yes. ELDAPRO generates complete permit plan sets from your project data in minutes and exports them as PDF, SVG, or DXF — no drafting software required.
