Permitting
Solar & EV Permit Packages
Permit-ready solar, battery storage, and EV charging documentation packages.
Overview
Solar photovoltaic, battery storage, and EV charging installations require complete permit documentation to satisfy the building department, utility interconnection requirements, and the installation contractor. We assemble the full permit package built to the exact submission format required by the applicable jurisdiction and utility. Packages are engineered for first-pass approval.
Why It Matters
Solar and EV permit packages are time-sensitive. An incomplete submission delays the inspection, delays the utility interconnection, and pushes the installation date. A professionally prepared package eliminates that delay and keeps the project moving.

Common Questions
Frequently asked.
Still have questions? Contact us and we will answer them directly before you submit an inquiry.
- Do I need a permit for a solar installation?
- Yes. In virtually all US jurisdictions, solar, battery storage, and EV charging installations require a building and/or electrical permit before installation.
- How long does permitting take for solar?
- Most jurisdictions process residential solar permits within 5-15 business days. CADTRI prepares packages built for first-pass approval to minimize correction cycles and installation delays.
- Can you handle commercial solar packages?
- Yes. Commercial packages have additional service load and structural requirements. We handle both residential and commercial scopes across all system sizes.
- What about battery storage and EV chargers?
- Both are included. Battery storage and EV charging installations require their own permit documentation and we handle all three as part of a combined package or individually.
