California architects face a specific documentation challenge every renewal cycle: proving that their five hours of Zero Net Carbon Design (ZNCD) continuing education were completed from a qualified provider and meet the California Architects Board‘s audit requirements. With the Board conducting random compliance audits and non-compliance carrying monetary penalties or disciplinary action, having the right records—and knowing exactly what those records must contain—is not optional. This guide walks through every documentation requirement, explains what auditors look for, and outlines a practical system for staying audit-ready from the moment you finish a course.
KEY TAKEAWAYS
| Point | Details |
|---|---|
| Retain records for two years | Documentation must be kept for at least two years from the date of license renewal, not just course completion |
| Seven required fields | Every certificate or record must include course title, subjects, provider name, educator name, completion date, hours, and a trainer knowledge statement |
| Audits are email-based | The Board sends audit requests via email from @dca.ca.gov; keeping your email current is critical |
| Online portal is preferred | Documentation can be submitted by you or your provider through the CAB’s CE Online Submission Portal |
| No Board-approved providers | The Board does not maintain an approved list; you are responsible for verifying provider and instructor qualifications |
| Recorded courses require a 70% test score | Non-live or recorded webinar courses require a post-course test with a passing score of at least 70% |
What Is the ZNCD Continuing Education Requirement?
Zero Net Carbon Design (ZNCD) continuing education became a mandatory condition of California architect license renewal following the enactment of Assembly Bill 1010, signed by Governor Gavin Newsom. The requirement is codified in Business and Professions Code Section 5600.05 and further clarified through California Code of Regulations, title 16, section 166.
ZNCD coursework addresses building design strategies that meet a structure’s energy demands or offset carbon-based energy consumption. Eligible topics include highly insulated building envelope design, deep energy retrofits of existing structures, natural ventilation and daylighting, passive solar design, and related approaches rooted in the practice of architecture—not carbon reduction in other industries.
California architects must complete the following CE hours during each two-year renewal cycle:
- Five (5) hours of disability access (ADA) continuing education
- Five (5) hours of Zero Net Carbon Design (ZNCD) continuing education
- A total of 10 CE hours before the license expiration date
Licenses expire on the last day of the architect’s birth month in odd-numbered years. Newly licensed architects must meet the CE requirement at their first renewal regardless of how recently they were licensed, and the law allows no waivers or extensions.
What Documentation Must You Retain?
The California Architects Board specifies exactly what your ZNCD completion records must contain. A generic attendance confirmation or a provider’s marketing email is not sufficient. Every document you retain for audit purposes must include all seven of the following fields:
- Course title — the full name of the course as offered by the provider
- Subjects covered — a description or summary of the ZNCD topics addressed
- Name of provider — the organization or individual offering the course
- Name of educator or trainer — the specific instructor who delivered the course
- Date of completion — the date you finished the course or passed the required test
- Number of hours completed — the total CE credit hours awarded (must equal five for the ZNCD requirement)
- Statement about the trainer’s or educator’s knowledge and experience — confirmation that the instructor meets the qualification standards under CCR section 166
All documentation must be retained for at least two years from the date of license renewal—not the date of course completion. If your license renews in September 2025, you must keep those records until at least September 2027.
How to Obtain a Valid Certificate of Completion
Most accredited ZNCD course providers issue a certificate of completion either at the conclusion of a live session or electronically within a defined window after course delivery. The method and timeline differ depending on course format.
Live In-Person or Live Webinar Courses
For courses delivered live—whether face-to-face or via live webinar—providers typically distribute certificates at the conclusion of the session. Because no post-course test is required for live delivery, the certificate can be issued immediately. Confirm before enrolling that the certificate will include all seven required fields, particularly the trainer knowledge and experience statement.
Recorded or Pre-Recorded Webinar Courses
Courses that are not presented live require a post-course test with a passing score of at least 70%. Providers have up to ten business days from the date you complete the test to grade it, confirm a passing score, and issue the certificate. Plan for this window when scheduling coursework close to a renewal deadline.
Requesting a Duplicate Certificate
If you lose your certificate or need a copy for an audit, you may request a duplicate from the course provider. Providers are required under the Board’s regulations to maintain records of completion and to supply a copy to a licensee upon written request within ten business days. If you are already subject to an active audit, the Board may contact the provider directly.
The Trainer or Educator Statement: What It Is and Why It Matters
The seventh required documentation element—the trainer or educator knowledge and experience statement—is the one most commonly missing from incomplete certificates, and its absence is a frequent cause of audit failures.
Under California Code of Regulations, title 16, section 166, a qualified ZNCD instructor must meet specific criteria. The Board defines a qualified trainer or educator as someone who has been involved in a minimum of three projects within the last ten years in the designing of carbon-neutral architecture, and who also meets at least one of the additional qualification requirements outlined in subsection (f) of the regulation.
Some course providers include this statement directly on the certificate of completion. Others—particularly live event organizers—require you to access it separately through your attendee account. When reviewing any ZNCD course, verify before you enroll how and where the instructor qualification statement will be provided.
What to Look For in a Trainer Statement
- The instructor’s name matching what appears on your certificate
- A description of their relevant project history in zero net carbon or carbon-neutral design
- Indication of a qualifying credential, certification, or professional standing consistent with CCR 166 requirements
- The statement provided in a format you can retain (PDF, printed page, or saved web page)
How the California Architects Board Audit Process Works
The California Architects Board is required by law to conduct CE coursework audits to determine compliance. These audits are conducted via a paperless process, and selection is random—any licensed architect may be audited in any renewal cycle.
The Audit Notification
If selected for an audit, you will receive an email from the Board requesting documentation. The email will come from an address ending in @dca.ca.gov. The Board specifically recommends keeping your email address current in your license record and setting an inbox rule that allows receipt of emails from that domain to avoid messages being flagged as spam.
Your Obligations as the Licensee
It is your responsibility—not the provider’s—to obtain the records requested by the Board and make them available. The regulations place an affirmative duty on licensees to cooperate fully and to take all steps needed to obtain required information, including providing any authorization or consent needed to release records from a provider.
Specifically, as the architect under audit you must:
- Respond to the Board’s email request promptly
- Gather all required documentation for the ZNCD courses completed during the relevant renewal period
- Contact your course provider if you need a duplicate certificate or supplemental trainer statement
- Submit all records through the CAB’s CE Online Submission Portal or by mail
Consequences of Non-Compliance
Failure to respond to an audit request, or failure to pass an audit, may result in a citation including a monetary penalty, or disciplinary action as determined appropriate by the Board. Non-compliant licensees are also required to complete the CE from the prior renewal period in addition to the CE required for the current renewal period, and must provide proof of remedying the deficiency before the end of the current renewal period.
Submitting Documentation: Online Portal vs. Mail
The Board offers two methods for submitting CE documentation during an audit. Understanding the difference matters for timing.
CE Online Submission Portal (Recommended)
The Board’s CE Online Submission Portal allows both architects and course providers to submit documentation electronically. This is the Board’s preferred method and results in the fastest audit processing. Either you upload your certificates and supporting documents yourself, or your course provider submits documentation on your behalf.
Access the portal at: cab.ca.gov → Licensees → CE Online Submission Portal
Mail Submission
Architects may also mail their documentation to the Board’s Sacramento office. However, the Board explicitly notes that mailing documentation may result in a delay in performing the audit. Given that audit response timelines matter for compliance determinations, the online portal is the strongly preferred option.
Comparing ZNCD Course Providers and Documentation Quality
The California Architects Board does not maintain an approved list of ZNCD providers and will not endorse any specific course or organization. That means the burden of selecting a provider whose documentation will hold up under audit falls entirely on you. The table below outlines key factors to evaluate when comparing providers.
| Factor | What to Look For | Red Flags |
|---|---|---|
| Certificate completeness | All seven required fields included on the certificate or available as a package | Certificates that list only course name and hours; no instructor name or subject summary |
| Trainer qualification statement | Statement provided as a downloadable document tied to the specific instructor | No mention of instructor credentials; generic bio without project history |
| Course content | Topics explicitly tied to ZNCD in architecture (building envelope, energy systems, passive design, etc.) | Generic “sustainability” content not specific to architectural practice or building design |
| Delivery format disclosure | Clear statement of whether course is live, recorded, or live webinar; test requirements disclosed upfront | Ambiguous delivery format; no mention of post-course test requirement for recorded courses |
| Duplicate certificate policy | Written policy for requesting duplicate certificates; stated response timeline | No policy; difficult to contact; certificates only available for 30–90 days after completion |
| AIA CES or other registry | Course registered with AIA CES, NCARB CE Registry, or similar system that maintains a transcript | No external registry; all record-keeping is solely on the provider’s internal system |
AIA members benefit from the AIA/CES transcript system, which provides a centralized continuing education record that can serve as documentation when requested during a Board audit. NCARB also maintains a CE Registry. While these transcripts may not replace the trainer knowledge statement, they provide a strong secondary record of course completion dates and hours.
Best Practices for Staying Audit-Ready
Building a simple but consistent documentation system eliminates virtually all risk of audit failure for ZNCD compliance. The following practices, applied consistently each renewal cycle, ensure you are ready to respond to an audit request within 24 hours.
Immediately After Course Completion
- Download the certificate of completion as a PDF and verify all seven required fields are present
- Save the trainer or educator knowledge and experience statement as a separate PDF if not included on the certificate
- Log the course in a personal CE tracking spreadsheet: provider name, course title, completion date, hours, and format
- Email yourself the certificate and any supporting documents as a backup
Before Each Renewal
- Confirm you have documentation for the full five hours of ZNCD completed within the renewal cycle
- Verify all seven documentation fields are present across all certificates; request any missing elements from your provider now, not during an audit
- Ensure your email address on file with the California Architects Board is current
- Set a rule in your email client to allow messages from @dca.ca.gov to your inbox
After Renewal
- Archive the complete documentation set for the renewal cycle in a dated folder
- Do not delete or move these files for at least two years from the renewal date
- If using cloud storage, verify folder permissions are set to retain files automatically
FAQ
Does the California Architects Board maintain an approved list of ZNCD course providers?
No. The Board does not have the authority to approve or endorse specific course providers or courses. You are responsible for selecting a provider whose subject matter content meets the ZNCD requirements and whose instructor has the knowledge and expertise required under CCR section 166. The Board provides links to AIA, NCARB, and SARA as examples of where eligible courses may be found, but that list is illustrative, not exhaustive.
What happens if I am audited and my certificate is missing the trainer knowledge statement?
An incomplete record may result in an audit failure. If you realize a document is missing before submitting to the Board, contact your course provider immediately. Under the regulations, providers are required to supply a copy of requested records to a licensee within ten business days of a written request. Request the trainer statement in writing, keep a record of that request, and submit all documents together through the CE Online Submission Portal.
Can my ZNCD course provider submit documentation to the Board on my behalf?
Yes. The Board’s CE Online Submission Portal allows documentation to be submitted by either the architect or the course provider. If your provider offers to submit on your behalf, confirm the submission has been completed and request a confirmation number or copy for your own records.
Do AIA continuing education hours count toward the California ZNCD requirement?
AIA Health, Safety, and Welfare (HSW) Learning Units from courses with ZNCD-eligible content can satisfy the California requirement, provided the course content meets the subject matter standards under CCR 166 and the instructor meets the educator qualification requirements. AIA/CES transcripts are widely accepted documentation, but you should also retain the provider’s certificate and trainer statement to satisfy all seven required fields.
How long must I retain ZNCD documentation after renewing my license?
A minimum of two years from the date of license renewal. Because the Board can audit any licensee at any point, retaining records for the full two-year period from renewal—not from course completion—is essential. Maintaining a permanent archive costs nothing and eliminates all risk associated with documentation loss.
Is there a passing score requirement for ZNCD courses?
Yes, but only for non-live courses. If you complete a recorded course or a pre-recorded webinar, you must pass a post-course test with a score of at least 70%. Live in-person and live webinar courses do not require a post-course test. Confirm your course’s delivery classification with the provider before enrolling if you are unsure.
What if I miss the CE deadline and my license expires?
When renewing an expired license, the required CE coursework—including the five hours of ZNCD—must have been completed within the 24 months prior to the date the license is renewed. The law does not allow any waiver or extension of this requirement. An architect renewing an expired license who cannot show CE completion within that 24-month window will need to complete the coursework before the renewal can be processed.
