Application Process

1. Create an Online Permit Center account at `cityofrc.us/onlinepermitcenter`, then start the matching Building & Safety application record.
2. Upload plans and supporting documents electronically. The city requires PDF uploads only; plan sheets should be in a single black-and-white PDF when possible, scaled/oriented correctly, and generally capped at 100 MB. Supplemental items such as calculations, reports, and studies are uploaded as separate PDFs.
3. After submission, staff reviews the application for completeness and formatting, then contacts the applicant within 2 business days for intake-fee payment.
4. Formal plan review then begins. The city says initial turnaround is about 10 to 15 working days, with many coordinated reviews handled concurrently by Building & Safety, Planning, Engineering, and Fire as applicable.
5. If corrections are issued, upload a corrected full plan set plus a response list. If approved plans later change, request a revision record from `EDRnotification@CityofRC.us` and upload revised sheets plus a narrative.
6. Once all reviews are approved, the city emails that the permit is ready. Permit issuance is handled by email and the Online Permit Center; the applicant must print the city-stamped plan set for use in the field.
7. Schedule inspections through the Online Permit Center after permit issuance.

Typical processing time: Intake-fee contact within 2 business days; formal plan review approximately 10 to 15 working days; city also states subsequent reviews are within 5 business days.

General Requirements

The city states all permits are applied for online and that a building permit is required for projects involving alteration of structures, in whole or in part, including architectural, landscape, demolition, and temporary facilities. Building and fire plan review applies to commercial, industrial, and residential construction projects.

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

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.

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.

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.

Fees

Minimum permit fee

The current Building & Safety schedule reviewed does not publish one universal minimum for every building permit type. It does list an hourly minimum including processing of $159 for Building & Safety services, and many permit types have their own flat or square-foot-based minimum entries.

Plan check fee

Plan Check (hourly) $159; MEP plan check (hourly) $159. Many permit categories also have bundled permit/processing fees by project type and size.

Permit fee formula

Mostly flat-fee and unit/square-foot schedules by permit type, with some hourly charges. The fee schedule says Building & Safety fees are adjusted annually and are subject to an additional 12% technology fee and/or 10% General Plan Maintenance Fee unless otherwise noted.

Reinspection fee

Building & Safety reinspection fee is $159 per hour; fire construction reinspection fee is $161 per hour where fire review applies. The municipal code separately authorizes violations enforcement for work performed without required permits.

Payment note

After application intake review, staff contacts the applicant within 2 business days for payment of the intake fee. The city materials reviewed did not publish detailed payment-method instructions on the main permit pages.

Fees change. Verify current amounts at the official fee schedule.

Work That Does NOT Require a Permit

• Detached one-story accessory structures such as tool sheds, storage sheds, and playhouses that do not exceed 120 square feet and 8 feet in height, if not located in required setbacks as determined by Planning
• Wood, chain-link, plastic, metal, or similar fences not over 6 feet high
• Masonry or concrete fences not over 3 feet above the lowest adjacent grade
• Residential flagpoles not exceeding 20 feet above ground
• Grading in an isolated, self-contained area when approved by the Building Official and when there is no danger to private or public property
• Excavation below finished grade for basements and footings authorized by a valid building permit, subject to the city's stated limits
• Cemetery graves
• Refuse disposal sites controlled by other regulations
• Excavations for wells, tunnels, or utilities
• Mining, quarrying, and similar material operations when lawfully established and not affecting adjacent support
• Exploratory excavations under soil engineers or engineering geologists
• Very small excavations or fills within the city's Appendix J thresholds, including certain cuts under 3 feet, fills under 1 foot, and soil work not exceeding 50 cubic yards on one lot and not obstructing drainage

Important: Rancho Cucamonga follows the adopted CBC/CRC exemption lists with local amendments; exemption from permit requirements does not authorize work that violates the municipal code, zoning, drainage, fire, or other applicable laws.
