CPC · California Plumbing Code
How are fees and reinspection fees set and applied?
In plain terms: the CPC lets each city/county set permit and reinspection dollar amounts in a local fee schedule (Table 104.5). The code permits charging a reinspection fee when work is not ready, corrections haven’t been made, plans aren’t available, access isn’t provided, or work deviates from approved plans, and the AHJ may withhold further inspections until that fee is paid (see §105.2.6).
Last reviewed: July 6, 2026
What the code requires — 2-4 sentences
The California Plumbing Code permits jurisdictions to set permit and inspection fees through a local fee schedule (see § 104.5) and to charge a reinspection fee when work is not ready or corrections have not been made. The code specifically allows a reinspection fee to be assessed for each inspection or reinspection in the circumstances listed in § 105.2.6. The CPC points inspectors and permit applicants to the adopted fee table (Table 104.5) for the dollar amounts and to the jurisdiction for the adopted fees.
The single most important rule: jurisdictions set the dollar amounts (Table 104.5) and a reinspection fee is permitted when an inspection is called for but the work is not ready or required corrections haven't been made; no further inspections will be performed until the reinspection fee is paid.
Requirements in detail
Key defined terms (first mention)
- Reinspection fee — the fee the Authority charges for an inspection or reinspection when the work is not ready or corrections remain (see § 105.2.6).
- Authority Having Jurisdiction (AHJ) — the local agency or official that enforces the CPC and adopts the local fee schedule (used throughout Chapter 1 and Division II).
- Fee schedule / Table 104.5 — the code’s required table format where jurisdictions list permit, plan-review, reinspection and other fees; jurisdictions determine the amounts.
Decision table — when and how fees / reinspection fees apply
| Decision dimension | Rule / value (what the AHJ may do) | Code Reference |
|---|---|---|
| Who sets dollar amounts for permits and reinspections | The jurisdiction adopts the fee schedule and determines amounts in Table 104.5. | § 104.5; Table 104.5 |
| When a reinspection fee is permitted | For each inspection or reinspection where the portion of work called for is not complete or required corrections have not been made. | § 105.2.6 |
| First-time rejection charging | The code does not require charging a reinspection fee the first time a job is rejected; the provision targets repeated/avoidable calls for inspection. | § 105.2.6 |
| Specific situations where reinspection fees may be assessed | Where approved plans are not available, where access is not provided on the scheduled date, or where work deviates from the approved plans without AHJ approval. | § 105.2.6 |
| Administrative steps required to obtain reinspection | Applicant must file the required application form (if the jurisdiction uses one) and pay the reinspection fee per the fee schedule before additional inspections are performed. | § 105.2.6; Table 104.5; § 104.5 |
| Related fees / separate fees | Plan-review fees, investigation fees (for work started without permit), and permit-issuance fees are separate and set by the jurisdiction; see the related fee sections. | § 104.3.2; § 104.5; § 104.5.2 |
Process summary (practical steps)
- The CPC directs jurisdictions to adopt fee schedules (Table 104.5) and charge fees accordingly.
- If an inspector finds work not ready or corrections outstanding, the AHJ may assess a reinspection fee and will not perform another inspection until that fee is paid. § 105.2.6 details these circumstances.
Exceptions & special cases
- First rejection: The code clarifies that charging a reinspection fee is not mandatory on the first time a job fails inspection; the intent is to discourage repeated premature inspection requests. § 105.2.6.
- Local implementation differences: The CPC provides the authority for jurisdictions to set fees; therefore a given city/county may adopt different application steps, forms, or fee amounts (all must be published in the local Table 104.5). The code does not specify dollar amounts.
- Other fees: Investigation fees (for work started without permit) and plan-review fees are separate and administered per § 104.5 and § 104.3.2. These may be charged in addition to reinspection fees where applicable.
Common mistakes
- Treating the CPC as specifying dollar amounts. The CPC requires a fee schedule format but does not set the local dollar amounts—the jurisdiction does (Table 104.5).
- Charging a reinspection fee on the first technical rejection as a matter of routine. The code says the provision “shall not be interpreted as requiring reinspection fees the first time a job is rejected.” § 105.2.6.
- Continuing inspections before payment. The code expressly permits the AHJ to withhold additional inspections until the reinspection fee is paid. § 105.2.6.
- Not publishing or making available the adopted fee schedule. The jurisdiction must determine and adopt fees and make them available for applicants referencing § 104.5 and Table 104.5.
Worked example (concrete scenario with numbers — HYPOTHETICAL fees)
Note: the CPC itself does not state dollar amounts. The numbers below are a hypothetical city schedule to illustrate application of the rules in § 105.2.6 and § 104.5.
Scenario:
- Jurisdiction X adopts Table 104.5 and lists: Permit issuance fee = $200, Plan review = $150, Reinspection fee (per inspection) = $125. (These amounts are examples only — jurisdictions set their own fees.)
- A plumber requests a rough-in inspection. Inspector arrives; piping is incomplete and corrections are required.
How the code-authorized process plays out:
- Inspector documents deficiencies and issues a rejection. Because this is the first failure, the AHJ may—but is not required to—charge a reinspection fee. § 105.2.6.
- Plumber returns after correcting items and requests reinspection. AHJ checks Table 104.5: reinspection fee = $125. Plumber must file any required form and pay $125 before the AHJ schedules/records the next inspection. § 105.2.6; Table 104.5.
- If the plumber had not provided approved plans on site or failed to provide access on the inspection date, the jurisdiction is similarly permitted to assess the $125 reinspection fee (same §).
- No further inspections will be performed until the reinspection fee is paid (explicit in § 105.2.6).
Related provisions
- § 104.5 — Fees are to be assessed per the fee schedule; jurisdictions determine and adopt the exact amounts.
- Table 104.5 — The format and line items for permit, plan-review, reinspection and other fees (jurisdictions fill in the amounts).
- § 104.3.2 — Plan review fees (separate from permit fees).
- § 104.5.2 — Investigation fees for work commenced before permit issuance.
- § 105.3 — Testing and retesting procedures for systems (inspections and retesting when tests fail).

[A] 109.1 Inspection. Inspections shall be in accordance with Sections 109.1.1 through 109.1.4.3.
[A] 109.1.1 General. Construction or work for which a permit is required by this code shall be subject to inspection by the code official and such construction or work shall remain visible and able to be accessed for inspection purposes until approved by the code official.
It shall be the duty of the permit applicant to cause the work to remain visible and able to be accessed for inspection purposes. Neither the code official nor the jurisdiction shall be liable for expense entailed in the removal or replacement of any material required to allow inspection.
Approval as a result of an inspection shall not be construed to be an approval of a violation of the provisions of this code or of other ordinances of the jurisdiction. Inspections presuming to give authority to violate or cancel the provisions of this code or of other ordinances of the jurisdiction shall not be valid.
Where required by the code official, a survey of the lot shall be provided to verify that the mitigation features are provided and the building or structure is located in accordance with the approved plans.
[A] 109.1.2 Authority to inspect. The code official shall inspect, as often as necessary, buildings and premises, including such other hazards or appliances designated by the code official for the purpose of ascertaining and causing to be corrected any conditions that could reasonably be expected to cause fire or contribute to its spread, or any violation of the purpose of this code and of any other law or standard affecting fire safety.

105.2.5 Responsibility. It shall be the duty of the holder of a permit to make sure that the work will stand the test prescribed before giving the notification.
The equipment, material, and labor necessary for inspection or tests shall be furnished by the person to whom the permit is issued or by whom inspection is requested.
105.2.6 Reinspections. A reinspection fee shall be permitted to be assessed for each inspection or reinspection where such portion of work for which inspection is called is not complete or where required corrections have not been made.
This provision shall not be interpreted as requiring reinspection fees the first time a job is rejected for failure to be in accordance with the requirements of this code, but as controlling the practice of calling for inspections before the job is ready for inspection or reinspection.
Reinspection fees shall be permitted to be assessed where the approved plans are not readily available to the inspector, for failure to provide access on the date for which the inspection is requested, or for deviating from plans requiring the approval of the Authority Having Jurisdiction.
To obtain reinspection, the applicant shall file an application therefore in writing upon a form furnished
for that purpose and pay the reinspection fee in accordance with Table 104.5.
In instances where reinspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid. 105.3 Testing of Systems. Mechanical systems shall be tested and approved in accordance with this code or the Authority Having Jurisdiction.

Frequently asked questions
Who decides the dollar amount of reinspection fees?
The local jurisdiction (the Authority Having Jurisdiction) decides and adopts the dollar amounts in their Table 104.5; the CPC requires the fee schedule format but not the amounts.
When can a reinspection fee be charged?
When the portion of the work called for is not complete, required corrections have not been made, approved plans are not available, access is not provided on the scheduled date, or the work deviates from approved plans — per § 105.2.6.
Can a jurisdiction charge a reinspection fee the first time the job fails?
The code states that the provision “shall not be interpreted as requiring reinspection fees the first time a job is rejected,” so charging first-time is discretionary, not mandatory.
Must the AHJ perform another inspection before payment?
No. The AHJ may withhold additional inspections until the required reinspection fees are paid. § 105.2.6.
Where do I find the local reinspection amount?
Inspect your jurisdiction’s adopted fee schedule (Table 104.5 as adopted locally) or contact the local building/plumbing counter — the CPC requires adoption but the amounts are local.
