Summary
Carlsbad's building official must run an expedited, administrative, nondiscretionary review for small residential rooftop solar systems under 10 kW AC (30 kW thermal). Review is capped to the Section 18.25.040 checklist, only one inspection is required, and approval issues administratively rather than through a public hearing.
The building official shall implement an expedited, administrative, nondiscretionary review process with reasonable restrictions for small residential rooftop solar energy systems. The building official's review of an application shall be limited to the requirements set forth in Section 18.25.040. If an application is deemed incomplete, a written correction notice detailing all deficiencies in the application and any additional information or documentation required to be eligible for expedited permit issuance shall be sent to the applicant for resubmission. ... Upon confirmation by the building official of the application and supporting documentation being complete and meeting the requirements of the eligibility checklist, the building official shall administratively approve the application and issue all required permits or authorizations.

Full Breakdown
5, requiring cities to streamline solar permitting. 020 as no larger than 10 kilowatts AC (or 30 kilowatts thermal) and installed on a single- or two-family dwelling. 040 (building, electrical, plumbing, mechanical and fire code compliance). If a submitted application is incomplete, the building official must send a written correction notice detailing every deficiency so the applicant can resubmit. Once the application and supporting documents meet the eligibility checklist, the building official administratively approves it and issues all required permits, though separate approval from the local utility is still needed before grid connection.
070, done in a timely, consolidated manner, with a separate fire inspection only if necessary. 54 only on a finding, backed by substantial evidence, that the installation poses a specific, adverse impact on public health or safety with no feasible mitigation; that denial or the CUP requirement can be appealed to the Planning Commission.
Violations & Fines
There is no fine schedule in Chapter 18.25 itself; the enforcement lever is procedural. An incomplete application draws a written correction notice rather than a fee, and a building official's denial of a minor conditional use permit, or a decision to require one, can be appealed to the Planning Commission under Chapter 21.54. Installing without a permit exposes the system to the city's general building code enforcement and stop-work authority.
