C-57 Well Drilling Contractor — Inactive License Certificate

An inactive certificate retains C-57 classification but does not authorize contracting until reactivation.

Licensing authority: California Contractors State License Board · Application information

Adding C 57 to an existing contractor license
Well Drilling (C-57) Examination
Existing license
The applicant already holds a California contractor license and seeks C-57 as an additional classification under BPC 7059(a). The qualifier must meet the experience requirements in C-57; supply the required additional-classification application and fee.
Inactive status
Adding the classification to an inactive license does not authorize contracting until reactivation.
Qualifying examination
The CSLB additional-classification instructions require the specific trade examination unless a waiver applies. A prior license or its qualifying evidence is an applicant condition; that earlier credential is not an additional examination leaf.
Adding C 57 with the statutory related classification waiver
No examination is required for this applicant pathway.
Experience
BPC 7065.3(b): at least four years of journeyman, foreman, supervising-employee or contractor experience in C-57 within the preceding ten years.
Qualifier record
BPC 7065.3(a): qualifier listed on personnel records of an active license in good standing, and actively engaged in that licensee’s construction activities, for five of the preceding seven years.
Related classification
BPC 7065.3(c): registrar determines that C-57 is closely related to existing classifications, or is a significant part of an associated general engineering or general building contractor’s construction business. A license held solely in limited specialty classifications does not qualify.
Waiver approval
This route applies to an additional classification approved without further examination under BPC 7065.3; eligibility and the registrar’s experience determination are applicant conditions.

The CSLB examination FAQ allows eighteen months from application acceptance to pass the assigned examinations; BPC 7065(d) recognizes qualifying examinations and service within the preceding five years.
Initial licensure based on recent qualifying service
Asbestos Open Book Examination (assessment without a question bank)
Asbestos completion
BPC 7058.5(b) requires the initial-license asbestos open-book submission even for applicants excused from the Law and Business and trade examinations; prior completion and the applicant-specific issuance instructions determine what must be resubmitted.
Background
BPC 7069 requires the applicable personnel background review and fingerprints; prior convictions and discipline are assessed under the controlling licensing statutes.
Business entity
Under BPC 7065(b)-(c), identify the applicant as an individual owner, partnership, corporation, LLC or participating tribe and use the corresponding owner, partner, responsible managing employee, officer, manager or member as qualifying individual. Corporations and LLCs supply Secretary of State identification; a participating tribal business supplies status verification.
Experience
Title 16 CCR 825 requires at least four years of journey-level, foreman, supervising-employee or contractor experience in the classification within the preceding ten years. Training or approved apprenticeship credit cannot exceed three years; a former qualifier may compute experience without the ten-year limit.
Implementation waiver wording
The current CSLB waiver application uses discretionary wording: "The examination may be waived if the qualifying individual has served as the qualifier for a licensee whose license was in good standing during the last five (5) years and the license was in the same classification for which they are applying". BPC 7065(d) controls the mandatory exemption.
Issuance
Complete the application and pay applicable fees under BPC 7066. For active issuance provide the $25,000 contractor bond under BPC 7071.6 and applicable qualifying-individual bond, workers compensation, and entity-specific bonds and insurance.
Military assistance
CSLB offers expedited application assistance to military veterans and eligible military spouses or partners. Transferable military training and experience are evaluated; expedited processing alone does not waive qualifying examinations.
Previous service
BPC 7065(d): the individual served as qualifier for a license in good standing in the same classification at any time within the preceding five years. No new Law and Business or C-57 examination is required on this service-based branch.
Probationary period
Under BPC 7077 every original license is probationary until renewal; an additional classification under BPC 7059 is excepted.
Score window
The CSLB examination FAQ allows eighteen months from application acceptance to pass the assigned examinations; BPC 7065(d) recognizes qualifying examinations and service within the preceding five years.
Renewal within five years after expiration
No examination is required for this applicant pathway.
Maintenance conditions
Submit an acceptable renewal application and pay renewal and applicable delinquency fees within five years after expiration under BPC 7141. No contracting is authorized during the expiration gap.

Official no-examination sources

Effective from 2026-09-22.

Continuance through a designated manager during military service
No examination is required for this applicant pathway.
Military manager
BPC 7071.3: holder of a current valid license entering military service may designate a managing person while in service and up to one year after discharge. Supply the designation within thirty days of entry, pay renewal fees, and use persons without disqualifying acts or crimes. The registrar may qualify designated persons in any manner adopted; an unnamed assessment is an applicant condition.

Official no-examination sources

Effective from 2026-09-22.

Military reinstatement after expiration during active service
No examination is required for this applicant pathway.
Active practice
This no-exam branch applies to the applicant who actively practiced the profession during service; BPC 114(c) allows the agency to require an examination for an applicant who did not practice. The separate discretionary-examination branch is retained as a secondary-route note.
Prior license
BPC 114(a): license was valid when entering active military service; apply during service or within one year after discharge or return to inactive military status, with the required affidavit and current renewal fee. Qualifying hospitalization time is excluded from the one-year limit.

Official no-examination sources

Effective from 2026-09-22.

Renewal relief during active military service
No examination is required for this applicant pathway.
Military service
BPC 114.3: license was current and valid when called to active duty; submit service documentation. Renewal requirements and fees are waived only for that period. Private practice is prohibited during waiver; military-active status for licensed military services follows 114.3(c). Meet renewal requirements within six months after discharge under 114.3(d).

Initial licensure with a qualifying personnel waiver request

All of the following:

BPC 7058.5(b) requires the initial-license asbestos open-book submission even for applicants excused from the Law and Business and trade examinations; prior completion and the applicant-specific issuance instructions determine what must be resubmitted.
Background
BPC 7069 requires the applicable personnel background review and fingerprints; prior convictions and discipline are assessed under the controlling licensing statutes.
Business entity
Under BPC 7065(b)-(c), identify the applicant as an individual owner, partnership, corporation, LLC or participating tribe and use the corresponding owner, partner, responsible managing employee, officer, manager or member as qualifying individual.

Experience
Title 16 CCR 825 requires at least four years of journey-level, foreman, supervising-employee or contractor experience in the classification within the preceding ten years.

Military assistance
CSLB offers expedited application assistance to military veterans and eligible military spouses or partners. Transferable military training and experience are evaluated; expedited processing alone does not waive qualifying examinations.
Probationary period
Under BPC 7077 every original license is probationary until renewal; an additional classification under BPC 7059 is excepted.
Registrar discretion
The registrar may waive the qualifying examination; the waiver is an applicant condition. The currently offered Law and Business and C-57 examinations remain involved unless excused; the asbestos submission remains required for initial issuance.
Score window
The CSLB examination FAQ allows eighteen months from application acceptance to pass the assigned examinations; BPC 7065(d) recognizes qualifying examinations and service within the preceding five years.
Waiver eligibility
BPC 7065.1(a): the individual was on official license personnel records and actively engaged in the same classification for five of the preceding seven years while that license was active and in good standing.
Reactivation of an inactive C 57 license
No examination is required for this applicant pathway.

Complete the application and pay applicable fees under BPC 7066. For active issuance provide the $25,000 contractor bond under BPC 7071.6 and applicable qualifying-individual bond, workers compensation, and entity-specific bonds and insurance.
License number
BPC 7075.1 permits reissuance of a prior number only for the specified unchanged individual or entity; a number reissue does not change original-license qualification requirements.
Military assistance
CSLB offers expedited application assistance to military veterans and eligible military spouses or partners. Transferable military training and experience are evaluated; expedited processing alone does not waive qualifying examinations.
Probationary period
Under BPC 7077 every original license is probationary until renewal; an additional classification under BPC 7059 is excepted.
Score window
The CSLB examination FAQ allows eighteen months from application acceptance to pass the assigned examinations; BPC 7065(d) recognizes qualifying examinations and service within the preceding five years.
Initial licensure by reciprocity

All of the following:

Asbestos completion
BPC 7058.5(b) requires the initial-license asbestos open-book submission even for applicants excused from the Law and Business and trade examinations; prior completion and the applicant-specific issuance instructions determine what must be resubmitted.
Background
BPC 7069 requires the applicable personnel background review and fingerprints; prior convictions and discipline are assessed under the controlling licensing statutes.
Business entity
Under BPC 7065(b)-(c), identify the applicant as an individual owner, partnership, corporation, LLC or participating tribe and use the corresponding owner, partner, responsible managing employee, officer, manager or member as qualifying individual. Corporations and LLCs supply Secretary of State identification; a participating tribal business supplies status verification.
Experience
Title 16 CCR 825 requires at least four years of journey-level, foreman, supervising-employee or contractor experience in the classification within the preceding ten years. Training or approved apprenticeship credit cannot exceed three years; a former qualifier may compute experience without the ten-year limit.
Issuance
Complete the application and pay applicable fees under BPC 7066. For active issuance provide the $25,000 contractor bond under BPC 7071.6 and applicable qualifying-individual bond, workers compensation, and entity-specific bonds and insurance.
Law exam
The California Law and Business Examination remains required, with an existing pass within the preceding five years recognized as stated in the CSLB application.
Military assistance
CSLB offers expedited application assistance to military veterans and eligible military spouses or partners. Transferable military training and experience are evaluated; expedited processing alone does not waive qualifying examinations.
Out of state license
The applicant holds an active license in good standing in a classification recognized by CSLB for the preceding five years, supplies license verification from the issuing authority, and applies for California licensure. Recognition and equivalent qualifications are decided by CSLB under BPC 7065.4. This is California adoption evidence; examinations belonging to another jurisdiction are not California requirement leaves.
Probationary period
Under BPC 7077 every original license is probationary until renewal; an additional classification under BPC 7059 is excepted.
Score window
The CSLB examination FAQ allows eighteen months from application acceptance to pass the assigned examinations; BPC 7065(d) recognizes qualifying examinations and service within the preceding five years.

No examination is required for this applicant pathway.
Maintenance conditions
Before expiration submit the prescribed renewal form and renewal fee under BPC 7140, and retain the qualification, bond and insurance requirements applicable to the license.
