CPC · California Plumbing Code
What does 'Accessible' and 'Accessible, Readily' mean in the CPC?
In the CPC, **Accessible** means you can get to the equipment but may have to remove an access panel or door first; **Accessible, Readily** means you can get to it directly without removing any panel or door (see **§ 203.0**).
Last reviewed: July 6, 2026
What the code requires — 2-4 sentences
The California Plumbing Code defines Accessible and Accessible, Readily in § 203.0. Accessible means there is access to a fixture, connection, appliance, or equipment but that access may first require removal of an access panel, door, or similar obstruction. Accessible, Readily means there is a direct access without having to remove a panel, door, or similar obstruction. § 203.0 is the controlling definition for both terms.
Plain-English rule: if you have to take a panel or door off (even with a screwdriver) the item is “accessible” — if you can get to it without removing anything it is “readily accessible.”
Requirements in detail
Key definitions (first mentions)
- Accessible — having access thereto, but which first may require the removal of an access panel, door, or similar obstruction. § 203.0
- Accessible, Readily — having a direct access without the necessity of removing a panel, door, or similar obstruction. § 203.0
Decision table — how to classify an item
| Decision dimension | If true → classification | Typical examples | Code Reference |
|---|---|---|---|
| Can be reached and operated without removing anything (no panels/doors to open or remove) | Accessible, Readily | Wall-mounted shutoff valve exposed on piping; floor cleanout with removable cap on top (cap removable but not behind a removable panel) | § 203.0 |
| Requires removal of an access panel, access door, or similar obstruction to reach the item | Accessible (but not “readily”) | Valve behind a removable sheet-metal panel, equipment behind a screw-fastened access plate | § 203.0 |
| Requires removal of building finishes or destructive access (not normal access panel) | NOT considered accessible under ordinary interpretation — may need design change | Appliance buried behind built cabinetry with no access panel | Definitions in practice; see § 203.0 |
Notes:
- The code makes the distinction by whether removal of a panel/door is necessary. There is no numeric clearance in the definition itself; the dividing line is the need to remove a panel/door. § 203.0
Exceptions & special cases
- The CPC definition itself does not list exceptions to the two terms; it simply defines them. For applicability in specific provisions (for example, gas valve accessibility or interceptor covers), the CPC elsewhere states when items must be “readily accessible” or “readily accessible for servicing.” Those operational requirements reference the same definitions in § 203.0. Examples in the code requiring “readily accessible” include shutoff valves and interceptor covers (see related provisions).
- If a listed device includes its own integral access (e.g., a listed grease interceptor with integral flow control permitted to be installed per manufacturer’s instructions), the installation location and access provisions in the specific section control while still using the definitions in § 203.0.
Common mistakes
- Assuming “accessible” = “readily accessible.” This is the single most common error; accessibility that requires removal of an access panel is not “readily accessible.” § 203.0
- Thinking “removable with tools” equals “readily accessible.” If you must remove screws or fasteners (i.e., remove a panel or door) the code’s text treats that as only accessible, not readily. § 203.0
- Confusing “readily accessible” with short distance or visibility alone. The definition hinges on removal of obstructions, not a specific distance. § 203.0
Worked example — concrete scenario with numbers
Scenario: A maintenance contractor locates a building’s main water shutoff valve inside a utility closet. The shutoff is mounted on piping 3 feet (0.91 m) from the closet door behind a 12 in. × 12 in. steel access plate that is attached with four stainless screws. The plate must be removed with a screwdriver to reach the valve.
- Apply the definition: because the valve cannot be reached without first removing an access plate (the removal of which is required to obtain access), the valve is Accessible but not Accessible, Readily. § 203.0
- Practical implication: if another section of the CPC (or a referenced installation requirement) demands the shutoff be readily accessible (for example for emergency operation), this arrangement would NOT comply unless the plate is replaced with a direct-access door or the valve is relocated so the operator can reach it without removing any panel. See related provisions where “readily accessible” is specified.
Related provisions (selected CPC sections)
- § 203.0 — Definitions (Accessible; Accessible, Readily).
- § 1210.9 — Manual gas shutoff valves: requires an accessible gas shutoff valve upstream of each gas pressure regulator (see subsections on accessibility).
- § 1210.9.1 — System shutoff valves shall be readily accessible for operation (example of where “readily accessible” is required).
- § 1009.5 — Interceptor (clarifier) cover location: covers shall be readily accessible for servicing and maintaining the interceptor.
- § 1014.3.4.3 (Access) — Gravity grease interceptors shall be located to be readily accessible to equipment required for maintenance.
(Use § 203.0 as the authoritative definition whenever the words “accessible” or “readily accessible” appear elsewhere in the CPC.)

Frequently asked questions
What if an access panel has quick-release fasteners — is that "readily" accessible?
If the access panel must still be removed (even with quick-release fasteners), the CPC definition treats that as removal of an access panel and therefore not “accessible, readily.” “Readily” requires direct access without removing a panel or door. § 203.0
Can a device be both "accessible" and "readily accessible" at the same time?
Legally the terms are mutually exclusive for a given installation condition: if direct access exists (no panel removal) it is “readily accessible”; if panel removal is required it is only “accessible.” Refer to § 203.0.
Does the CPC give a measurement (distance/clearance) test for "readily accessible"?
No. The CPC definition turns on whether removal of a panel/door is necessary, not a numeric clearance. For clearance/operability requirements you must check the specific section that mandates access (for example, shutoff valves or interceptors) in addition to § 203.0.
If a device is behind a locked door but operated without removing a panel, is it "readily accessible"?
If the door is opened in normal operation (a keyed door that facility personnel can open during operation), that may still be “readily accessible” because no panel removal is required. But if access requires special tools or destructive work, then it is not “readily accessible.” Check the specific section's intent and AHJ expectations; the definition in § 203.0 focuses on panel/door removal.
Who decides whether an installation meets "readily accessible" in practice?
The Authority Having Jurisdiction (AHJ) enforces the CPC and will evaluate installations against § 203.0 and the particular equipment/section requirements (for example, gas valves or interceptors that explicitly require “readily accessible”).
