California Natural Gas Service Directory
Research gas provider identification, meter questions, gas line extensions, and all-electric alternatives.
Why natural gas matters
Natural gas may affect appliance choices, meter capacity, line extensions, or whether an all-electric ADU is a cleaner scope.
No automatic parcel-level answer
California utility service is fragmented across cities, counties, utility providers, sanitation districts, water districts, environmental health agencies, special districts, and private infrastructure. Use this page as a research starting point only.
How to research this utility
- Identify the APN and address.
- Confirm city versus unincorporated county jurisdiction.
- Identify the provider or agency that controls this utility.
- Check service boundary, GIS, permit, or provider resources where available.
- Ask whether connection, capacity, fees, easements, trenching, or extensions apply.
- Request written confirmation where possible.
Evidence worth collecting
Confirm the gas provider and whether active service or a main is actually available to the parcel. Collect meter and service records, proposed appliance loads, route constraints, and any provider correspondence. Also document the all-electric alternative so the project team can compare complete scopes.
Keep these costs separate
Separate provider connection work, trenching, meter changes, private piping, appliance conversion, testing, and the cost comparison for an all-electric design.
Decision checkpoint before design
Do not treat this utility as resolved until the serving agency or qualified professional has been identified, the parcel has been matched to the relevant record or service boundary, and the likely connection or on-site system path has been described. Record what remains conditional, what study or application comes next, how long that step may affect the project sequence, and which design assumption depends on the answer. Carry a contingency for conditions that cannot be confirmed before excavation, engineering, or formal review.
Natural Gas red flags
- No gas main nearby
- Line extension required
- Meter capacity unknown
- Electrification rules or design choice affects scope
Questions to ask
- Who provides gas service?
- Is there an existing meter?
- Is a gas line extension needed?
- Would all-electric design avoid gas work?
