Two Permits, One Project: Does Each Permit Need Its Own Title 24 Report?
The document requirement is written per permit application: each application subject to Part 6 must carry the certificate of compliance. The code does not say how to divide one project across several permits, so ask the department whether one CF1R may serve them all. Every installer's certificate states the permit number it was performed under.

The rule is written per application
Part 1, Section 10-103(a)2 says each application for a building permit subject to Part 6 shall contain at least one copy of the compliance documents. A mechanical or solar permit pulled by a subcontractor is an application like any other if the work touches regulated features. Whether it joins the main set or stands alone is the counter's call.
A typical split
- The general contractor's building permit, which carries the CF1R in the plan set.
- The HVAC contractor's mechanical permit. For a change-out, the manual allows the registered CF1R-ALT-02 at final inspection where plans are not required with the permit.
- The solar installer's permit, with its own installation certificate.
- A window or water heater installer's permit, which may need only a simplified form, or none, if the department chooses under Section 10-103(a)1C.
Where the permit number appears
A certificate of installation must state the number of the building permit under which the work was performed (Section 10-103(a)3B), and so must a certificate of verification. The person in charge of each installation signs for that portion, or the person with chief responsibility signs for the whole scope. At inspection the department checks that these certificates are posted or available "with the building permit(s) issued for the building", wording that expects several permits for one building (Section 10-103(d)2).
When one permit changes the other
If a specification changes before final construction so the building may no longer comply, amended plans and certificates go back to the department (Section 10-103(a)2B). A subcontractor's substitution can therefore reopen the CF1R on the main permit, as different equipment than the CF1R describes. Register the revised copy and replace it in every file that holds the old one.
What to do
Tell the department how many permits there are and which carries the CF1R. Give each trade its feature list from who supplies which input. Signers are covered in who can prepare a report, and HVAC paperwork in HVAC replacement permits. Our residential reports include revisions until the project complies.

Frequently Asked Questions
Only if the department accepts it. The code requires the documents with each application but sets no rule for splitting a project, so ask which document goes in which file.
The person in charge of the installation signs for their portion, or the person with chief responsibility signs for the entire scope of work.
