Required documents
- Online application
- plan set uploaded electronically
- separate supplemental PDFs for calculations, specifications, reports, and studies as applicable
- re-submittals require a corrected full plan set plus response list
- revisions require revised sheets plus a narrative. Applicants must keep a printed city-stamped permit set in the field after issuance
- Building code
- For plans filed on or after January 1, 2026, the city reviews under the 2025 California Building, Residential, Electrical, Mechanical, Plumbing, Green Building Standards, and Energy Codes. Rancho Cucamonga adopted local amendments by Ordinance No. 1048 on November 19, 2025.
- Permit validity
- Rancho Cucamonga Municipal Code treats work done under a permit that "subsequently expired and became null-and-void" as unpermitted. The city ordinance reviewed does not publish a separate local expiration period; inference: because Ordinance No. 1048 amends selected local code sections but does not amend CBC/CRC permit-expiration sections, default California code expiration rules likely apply unless the city states otherwise on the permit record.
- Owner-builder
- Owner-builder permits are allowed as an exception for Group R, Division 3, or Group U occupancies with Building Official approval. The city's 2025 owner-builder notice requires the property owner to acknowledge labor, insurance, tax, and resale risks before permit issuance.
- Contractor requirements
- No electrical permit is issued until a valid California contractor license of the correct classification is presented. The city also states contractors are required by law to be licensed and bonded in California and to list license numbers on permits and contracts.
