CFC · California Fire Code
What plans and approvals are required for airports, heliports and hangars?
For homeowners: the CFC says Chapter 20 governs airports, heliports and hangars (you must follow the chapter) and if the chapter doesn’t spell something out you must follow nationally recognized standards (like NFPA or FAA). On plans you need to state that Chapter 20 applies, list which outside standards you’re following, and include evidence for required items such as rooftop standpipe reach, extinguisher locations, suppression designs and FAA approval for heliports.
Last reviewed: July 6, 2026
What the code requires — 2–4 sentences
The California Fire Code requires that airports, heliports, helistops and aircraft hangars be regulated under Chapter 20 — in short, the chapter applies to those facilities (§ 2001.1) and where the chapter does not specify a requirement the authority must follow nationally recognized standards (for example NFPA standards or FAA requirements) (§ 2001.2) . In practice this means the CFC sets the scope and some prescriptive elements in Chapter 20, but many plan and approval details (design standards, suppression classification, federal approvals) reference outside standards identified in the chapter and other CFC sections .
The single most important rule: Chapter 20 controls airports/heliports/hangars; anything Chapter 20 doesn't cover must follow nationally recognized standards (see § 2001.1 and § 2001.2) .
Requirements in detail
Summary: The CFC establishes the applicability (scope) and directs that unspecified regulations follow national standards. For specific plan and approval items you will normally need to show compliance with Chapter 20 provisions and with the referenced standards (NFPA, FAA, building code), and obtain any permits called out by Chapter 1/Section 105 (see examples below) file.
What the controlling sections say (plain)
- § 2001.1 — Scope: “Airports, heliports, helistops and aircraft hangars shall be in accordance with this chapter.” This makes Chapter 20 the starting point for plans and approvals .
- § 2001.2 — Regulations not covered: “Regulations not specifically contained herein … shall be in accordance with nationally recognized standards.” That means any gaps in Chapter 20 are filled by the referenced standards (NFPA 409, NFPA 418, FAA guidance, etc.) .
Typical plan/approval items you must show on the submittal
(What plan reviewers and the authority having jurisdiction will expect — grounded in Chapter 20 plus the chapter’s instruction to use national standards.)
- Facility applicability statement referencing § 2001.1 (that the project is an airport/heliport/hangar and Chapter 20 applies) .
- Identification of the nationally recognized standards used where Chapter 20 is silent (e.g., NFPA 409 for hangars; NFPA 418 for heliports) as required by § 2001.2 file.
- Permits called out by Chapter 20 or cross-referenced sections (for example permit references for rooftop heliports and for certain fuel‑handling operations — see Section 105.5 and cross references) file.
- Fire protection design documentation when required by Chapter 20 or the referenced standards (sprinkler/foam design, standpipe extension, portable extinguisher locations) — see Chapter 20 sections for helistops/heliports and the hangar fire suppression direction in CFC/CBC cross references file.
Decision-relevant dimensions, thresholds and required documentation
| Decision item | Threshold / Value | What plan reviewers expect to see | Code Reference |
|---|---|---|---|
| Applicability (Chapter coverage) | N/A — any airport/heliport/helistop/hangar | Statement on plans that Chapter 20 applies | § 2001.1 |
| Use of outside standards | When Chapter 20 is silent | Citation on plans of the specific nationally recognized standards used (e.g., NFPA 409, NFPA 418) | § 2001.2 |
| Helistop / Heliport touchdown clear area | Average 15 ft, minimum 5 ft at any point | Dimensioned roof/plan showing clear area and drains | § 2007.2 |
| Rooftop standpipe reach | All portions within 150 ft of a 2½‑inch outlet | Standpipe riser/plan showing outlet locations and extension to roof | § 2007.5 |
| Portable extinguisher rating | Minimum 80‑B:C per takeoff/landing area | Locations and extinguisher schedule on plan | § 2007.7 |
| Rooftop heliport approvals | Federal approval required before operating | Evidence of FAA approval (letter/permit) in submittal | § 2007.8 |
| Hangar fire suppression trigger | Door height > 28 ft or other listed triggers | Fire suppression design per NFPA 409 (or CBC/CFC cross refs) | CBC/CFC cross refs and NFPA 409; see hangar guidance and Table references (e.g., Group I required where door height > 28 ft) file |
| Fuel quantity thresholds (hazardous operations) | 1,600 gallons (unsprinklered single fire area); 7,500 gallons (max single fire area for certain sprinklered hangars) | Fuel inventory and operations description; suppression and foam plans if thresholds exceeded | § 914.8.3 (hazardous operations list) |
Notes: The table above pulls the specific decision thresholds that plan reviewers use from Chapter 20 and related CFC/CBC sections and tables; Chapter 20 sets the scope and directs the use of referenced standards when details (such as sprinkler design per NFPA) are required by the chapter file.
Plans, attachments and evidence commonly required on the submittal
- Site plan showing aircraft operation area (AOA) boundaries, fueling points, and fire department access roads (Chapter 20 requires fire apparatus access in accordance with Chapter 5) .
- Fuel systems/fueling operation plans (if applicable) and permits (CFC Chapter 20 emphasizes fuel handling; see cross references to Chapter 57/23) .
- Fire protection drawings: sprinkler/foam systems (if required by hangar classification or heliport rules), standpipe risers to rooftop heliports, extinguisher locations and ratings (see § 2007.5–2007.7) .
- Statement of which nationally recognized standards are being applied for items not specifically covered in Chapter 20 (to satisfy § 2001.2) .
- When applicable, FAA approval documentation for heliport operations (required before operation under § 2007.8) .
Exceptions & special cases
- Chapter 20 is the baseline: anything the chapter does not prescribe must be resolved under a nationally recognized standard (e.g., NFPA 409 for hangar suppression; NFPA 418 for heliports) per § 2001.2 — you must identify which standards you used on plans file.
- Rooftop heliports/helipads have additional rooftop-specific requirements (standpipe extension, foam capability, drainage, noncombustible supports) that are in Chapter 20, and federal approval is required before operation (§ 2007.5–2007.8) .
- For permits specifically tied to fuel-handling vehicles, hot work, or finishes the Chapter points to Section 105.5 (permits) — confirm with your jurisdiction which 105.* permits are required (Chapter 20 references these permit cross‑links) file.
Common mistakes
- Failing to state on the plans which nationally recognized standards are being used to fill gaps in Chapter 20 (required by § 2001.2) — this delays review .
- Omitting FAA approval documentation for rooftop heliports before requesting operational approval (Chapter 20 explicitly requires federal approval for heliports) (§ 2007.8) .
- Not dimensioning the helistop clear area (15 ft average, 5 ft minimum) and drainage provisions so fuel spillage is confined and routed away from exits (§ 2007.2, § 2007.3) .
- Assuming Chapter 20 covers all technical design (sprinkler/foam/standpipe); in many cases the code requires design to NFPA standards — reviewers expect NFPA‑level calculations and specifications where the chapter references them (§ 2001.2, plus the specific Chapter 20 sections) file.
Worked example — concrete scenario
Scenario: You are submitting plans for a rooftop heliport on a commercial building.
- On the cover sheet state that the project is a heliport and that Chapter 20 applies per § 2001.1; list the nationally recognized standards you will use for items not detailed in Chapter 20 (for example NFPA 418) to satisfy § 2001.2 file.
- Show the touchdown/landing pad with the 15 ft average clear area and 5 ft minimum clearances at roof level, dimensioned on the plan (to comply with § 2007.2) and show graded/drainage to confine spillage per § 2007.3 .
- Show standpipe extension and that all portions of the helistop are within 150 ft of a 2½‑inch outlet; include riser detail and roof outlet locations as required by § 2007.5 .
- Provide a portable extinguisher schedule showing at least one 80‑B:C extinguisher for the landing area per § 2007.7 and include inspection/installation notes .
- Attach a copy or evidence of FAA approval (required before operation under § 2007.8) and include any permit application number (many jurisdictions also require a rooftop heliport permit referenced at Section 105.5) file.
- If any fuel handling, foam system or fire suppression design is triggered, include NFPA‑compliant calculations and shop drawings (per Chapter 20 direction to follow national standards) — cite NFPA documents on the plans per § 2001.2 file.
Related provisions (CFC / cross references)
- § 2001.1 — Scope (Chapter 20 applies to airports, heliports, helistops, hangars)
- § 2001.2 — Regulations not covered; follow nationally recognized standards (must be cited on plans)
- § 2001.3 — Permits (Chapter 20 cross‑references permit requirements; see Section 105.5)
- § 2007.2–2007.8 — Helistops and heliports: clearances, drainage, standpipe, foam, extinguishers, and FAA approval (see § 2007.2, § 2007.3, § 2007.5–§ 2007.8)
- § 914.8 / § 914.8.3 — Aircraft-related occupancies and hangar fire suppression thresholds (hazardous operations list and fuel thresholds) file
- NFPA standards referenced in Chapter 20 and elsewhere (e.g., NFPA 409 for hangars; NFPA 418 for heliports) — cite them on your plans as the nationally recognized standards per § 2001.2

Frequently asked questions
What exactly must I write on the cover sheet about standards?
State that Chapter 20 applies (per § 2001.1) and list the nationally recognized standards you will use to address any items not explicitly detailed in the Chapter (as required by § 2001.2) .
Do I need FAA approval to submit plans for a rooftop heliport?
You need FAA approval before operating the heliport; Chapter 20 requires federal approval before operation (§ 2007.8). Check with your local permitting authority whether they require FAA documentation with the plan package for completeness .
When does a hangar require a specific fire suppression design?
The CFC/CBC/NFPA cross references require suppression based on hangar classification and triggers such as door height > 28 ft or listed hazardous operations and fuel‑quantity thresholds; these triggers are enforced through the hangar provisions and NFPA 409 direction referenced in the code (see § 914.8.3 and related CBC/CFC cross refs) file.
Are specific permits mentioned in Chapter 20?
Chapter 20 references permits and points plan preparers to Section 105.5 for permits (for example fueling vehicles, hot work, rooftop heliport permit cross references). Confirm permit numbers and local permit submittal requirements with your jurisdiction’s permit desk file.
If Chapter 20 is silent on an item, can I choose any standard?
No — you must use nationally recognized standards appropriate to the item (NFPA, FAA, etc.) and explicitly identify them on the plans as required by § 2001.2; the authority having jurisdiction may require particular standards (e.g., NFPA 409 for hangars) file.
