How long does EV charging station installation take?

From site assessment to revenue generation: 4–6 months typical. This includes 2–4 weeks for design, 4–8 weeks for permitting, 2–6 weeks for electrical work, 1–2 weeks for charger installation, and 1 week for activation and testing. For the Section 30C deadline (June 30, 2026), you need to start immediately — three months doesn't allow time for permitting delays.

What electrical upgrades are needed for EV charging?

Most properties need panel upgrades ($10,000–$30,000), transformer replacement ($20,000–$80,000), and potentially new service lines ($15,000–$50,000). A parking lot with 150-amp, 240V service at 40% utilization could support 4–6 Level 2 chargers or 1 DC fast charger without upgrades. For 20+ chargers, transformer and panel upgrades are non-negotiable.

How do I qualify for the Section 30C EV charging tax credit?

Required documentation includes proof of purchase, installation documentation, equipment specifications, electrical capacity assessment, and proof that stations were placed in service before June 30, 2026. File Form 8911 with your tax return.

What permits are required for EV charging installation?

You typically need an electrical permit (required everywhere), building permit (often required for parking lot improvements), utility approval (for load and interconnection), potentially environmental review (CEQA/NEPA in some jurisdictions), and ADA compliance review. Total permitting timeline is 10–22 weeks.
