* Costs are estimated for 2022 and do not include the cost of transformers or increase panel capacity. Assuming 1.5 parking spaces per dwelling unit. ** The “% of total construction cost” may be as high as double as what is when accounting for transformers, etc. This is especially true of ‘Option A’ which includes the highest power requirements.

EV Charging Cost Estimates
The following cost estimates are from a 2019 study prepared for Peninsula Clean Energy (PCE) and Silicon Valley Clean Energy (SVCE) analyzing the costs for: 1) a 60-unit multi-family project; 2) a 150-unit multi-family project; and 3) an office building with 60 parking spaces. The costs below are for EV Ready and do include costs for transformers. This study does not include costs for EVSE, and does not include and has a overall 20% contingency to account for ADA compliance. ADA can be a significant source of cost and in this study is only intended to capture a limited scope of ADA compliance.
