Near-Home Public Charging Demand From EVs Without Home Charging: Senate Bill 1000 Assessment

Overview 
The map displays quarter-mile hexagons that show concentrations of public charging market demand from electric vehicles (EVs) estimated to lack home charging and nearby public charging within 2 miles. Additional layers can be toggled on and off to view locations of low-income or disadvantaged communities, urban or rural areas, and federally recognized tribal lands.*

Results are based off model estimates from the SB 1000 assessment. See the 2026 SB 1000 Staff Report for a full description of data sources and methodology.

While EVs without home charging may access charging in a variety of ways, this map shows market demand for two types of near-home public charging:

• Nearby charging: Public Level 2 or direct-current (DC) fast charging within two miles of households that can be used for short-duration charging.
• Walking-distance charging: Public Level 2 charging within an eighth of a mile of households that can be used for long-duration charging such as overnight charging

While the above scenarios are used for this assessment, staff note that the availability of near-home public charging is subject to many variables, potentially including existing land use, zoning, and local permitting.

Two utilization options for public charging capacity are available:

• Under the high utilization option, a public Level 2 charger that is located within an eighth of a mile of households (walking distance) can adequately serve 5 EVs without home charging (3 EVs overnight on separate nights and 2 EVs during the day). A public DC fast charger that is located within two miles of households (within the neighborhood) can adequately serve 30 EVs without home charging during the day. Public DC fast chargers would not be used for long-duration charging, such as overnight charging.
• Under the low utilization option, a public Level 2 charger that is located within an eighth of a mile of households can adequately serve 3 EVs without home charging (2 EVs overnight on separate nights and 1 EV during the day). A public DC fast charger that is located within two miles of households can adequately serve 20 EVs without home charging during the day. Public DC fast chargers would not be used for long-duration charging, such as overnight charging.

* The CEC purchased property and parcel boundary data from CoreLogic, Incorporated that includes information on parcel location, ownership, tax assessment, and property characteristics. This data was used to estimate home charging barriers and likeliness of not having a home charger. In general, tribal lands are exempt from local and state taxation, including property taxes. Therefore, property data to assess barriers to having a home charger may be sparse in federally recognized tribal lands. 

Navigate Layers, Legends, and Basemaps 
The default map layer shows market demand for public nearby charging from EVs in 2024. EVs contribute to market demand if they are estimated to lack home charging and do not have sufficient existing public Level 2 or DC fast charging within 2 miles of home.

Identify Potential Sites

• If the goal is to see market demand for public nearby charging within low-income or disadvantaged community areas, turn on the Low-income or Disadvantaged Community layer and Public Nearby (2-miles) Charging Demand From EVs Without Home Charging (high or low utilization option) layer.
• Alternatively, if the goal is to see market demand for public walking-distance charging within an urban or rural area, turn on the Urban or Rural layer and Public Walking-Distance (1/8th mile) Level 2 Charging Demand From EVs Without Home Charging (high or low utilization option) layer.

100% EV Future – A hypothetical scenario where all vehicles registered in 2024 are electric. 

Charger – The system within an electric vehicle supply equipment (EVSE, defined as a device with one or more charging ports and connectors for charging EVs) that charges one EV. A charger may have multiple connectors, but it can provide power to charge only one EV through one connector at a time. Also referred to as a charging port. 

Charging Station – A physical address where one or more chargers are available for use. This is the same usage as for “gas station.” A charging station can be public, shared private, or private.  

Direct Current Fast Charging – Electric vehicle charging anywhere from 200 to 1,000 volts using direct current.   

Disadvantaged Communities – Census tracts that score within the top 25th percentile of the Office of Environmental Health Hazards Assessment’s California Communities Environmental Health Screening Tool (CalEnviroScreen) 4.0 scores, as well as areas of high pollution and low population, such as ports.  

Electric Vehicle (EV) – A broad category that includes all vehicles that can be fully powered by electricity or an electric motor. 

Federally Recognized Tribal Lands – Lands under control of federally recognized tribes, including American Indian/Alaska Native/Native Hawaiian entities for which the Census Bureau publishes data, which consist of federally recognized American Indian Reservations and Off-Reservation Trust Lands (ORTL). 

High Utilization Option – A public Level 2 charger that is located within an eighth of a mile of households (walking distance) can adequately serve 5 EVs without home charging - 3 EVs overnight on separate nights and 2 EVs during the day. A public DC fast charger that is located within 2 miles of households (within the neighborhood) can adequately serve 30 EVs without home charging, all during the day since DC fast chargers would not be used for long-duration charging, such as overnight charging. 

Level 2 Charging – Electric vehicle charging at 240 volts using alternating current. 

Low-income Communities – Census tracts with median household incomes at or below 80 percent of the statewide median income or with median household incomes at or below the threshold designated as low income by the Department of Housing and Community Development’s list of state income limits adopted pursuant to Section 50093 of the California Health and Safety Code. 

Low Utilization Option – A public Level 2 charger that is located within an eighth of a mile of households (walking distance) can adequately serve 3 EVs without home charging - 2 EVs overnight on separate nights and 1 EV during the day. A public DC fast charger that is located within 2 miles of households (within the neighborhood) can adequately serve 20 EVs without home charging during the day. 

Multifamily home (MFH) – A classification of housing where separate housing units for residential inhabitants are contained within one building or several buildings within one complex. Units can be next to each other (side-by-side units) or stacked on top of each other (top and bottom units). A common form is an apartment building. Many intentional communities incorporate multifamily residences, such as in cohousing projects.  

Rural – Census tracts where less than 10 percent of the tract’s land area is designated as urban by the Census Bureau using the 2020 urbanized area criteria. 

Rural Center – Contiguous urban census tracts with a population of less than 50,0000. Urban census tracts are tracts where at least 10 percent of the tract’s land area is designated as urban by the Census Bureau using the 2020 urbanized area criteria. 

Single-family home (SFH) – Units that are separated by a ground-to-roof wall, have separate heating system, individual meters for public utilities, and no units located above or below. May include fully detached, semi-detached, row houses, duplexes, and townhomes. 

Urban – Contiguous urban census tracts with a population of 50,000 or greater. Urban census tracts are tracts where at least 10 percent of the tract’s land area is designated as urban by the Census Bureau using the 2020 urbanized area criteria.
