LP‑Gas, CNG & Fueling / Dispensing
This hub orients readers to CRC‑relevant rules for LP‑gas and CNG storage, equipment, fueling/dispensing, permits and key safety requirements.
Last reviewed: July 6, 2026
Overview
This hub covers the CRC-relevant regulation of liquefied petroleum gas (LP‑gas) and compressed natural gas (CNG) used for residential and vehicle fueling — including storage, equipment approvals/listing, installation, dispensing and safe handling. LP‑gas specifics are addressed through Chapter 61 (LP‑gas) and related motor‑fuel dispensing rules, while CNG vehicular fueling is governed by the motor fuel‑dispensing provisions that incorporate NFPA/IFGC installation requirements (see Chapter 61 §6101.1 and the motor‑fuel sections).
Key operational and safety topics you’ll find in these provisions include required approvals/listing of containers, dispensers and hoses; limits and listing requirements for residential fueling appliances; emergency shutdown and overfill prevention; and siting/separation distances for dispensing and storage. Examples: LP‑gas dispensing rules at §2307 (approvals, attendants, separation) and CNG residential appliance/listing and location rules at §2308 (including RFA limits and emergency shutdown requirements).

Frequently asked questions
Do I need a permit to install LP‑gas or CNG fueling equipment at a residence?
Yes. Permits are required for LP‑gas installations and related dispensing equipment as specified in the code (see §6101.2), and motor‑fuel dispensing installations are subject to plan review and permit requirements under the applicable motor‑fuel sections.
Where do the codes set separation, location and protection requirements for dispensers and storage?
Separation and siting requirements for LP‑gas dispensers and containers are in the motor‑fuel dispensing provisions (for example §2307.4), and CNG compression/storage/dispensing location and separation rules are in §2308.3 and §2308.3.1, which also address exceptions and distances from buildings, lot lines and power lines.
Can I install a residential CNG fueling appliance (home refueling unit)?
Yes, but residential fueling appliances (RFAs) must be listed and installed per the listed standards and are capacity‑limited (the code caps RFAs as specified in §2308.2.3). Nonresidential vehicle fueling appliances have separate listing and capacity requirements.
