Building department
- Address
- 10500 Civic Center Drive, Rancho Cucamonga, CA 91730
- Phone
- (909) 488-4668 (permitting questions); (909) 303-1786 (information about scheduled inspections); (909) 477-2710 (questions about inspections or inspection timeframes)
- Office hours
- In-person visits are published for "Monday through Thursday", "7:00 am to 4:30 pm". FRIDAY IS NOT MENTIONED ANYWHERE ON THE PAGE - a control read confirmed the word does not appear - so this record states that Friday is absent from the published schedule rather than asserting the office is closed, which the city does not say. Note also that going in person does not get you a permit: see the online-only rule below.

Codes adopted
California publishes its building standards as Title 24, adopted by state agencies and republished on a three-year cycle. A city or county may change those standards only after its governing body makes an express finding that the change is reasonably necessary because of local climatic, geological, or topographical conditions, and no change becomes operative until the finding and the change have been filed with the California Building Standards Commission.
- 2025 California Building Standards Code (Cal. Code Regs., Title 24) - published July 1, 2025 by the California Building Standards Commission, effective January 1, 2026. Health & Safety Code 18938(b): building standards adopted into the California Building Standards Code "shall apply to all occupancies throughout the state and shall become effective 180 days after publication."
- THE CITY'S OWN ADOPTING ORDINANCE WAS NOT READ FOR THIS RECORD, so no Rancho Cucamonga ordinance number or local effective date is asserted here.
Permit types & fees
Rancho Cucamonga's permit history isn't searchable here yet
This page covers what the permit requires. What we don't have for Rancho Cucamonga yet is the record of permits actually issued — the history you'd search by street address. That is a gap in our coverage, not a statement about any particular property.
Your email, and the place — never an address. We only use it to tell you when Rancho Cucamonga lands. Privacy.
Tips & gotchas
- THIS IS THE ONE CITY IN THIS CORPUS WITH NO COUNTER ISSUANCE AT ALL. "Please note we do not issue permits over the counter, and our process is done 100% online." Every other California record here is built around counter hours and cut-off times; in Rancho Cucamonga those are the wrong question entirely. The in-person hours are real, but they are not a route to a permit.
- MAIL IS ROUTED BY WHAT YOU ARE BUILDING, NOT BY WHO YOU ARE. CDtech@CityofRC.us handles "Solar, Reroofs, and Patio covers permit issuance"; EDRnotification@CityofRC.us handles "All other permits and technical permit questions". Sending a solar query to the general address, or vice versa, puts it in the wrong queue.
- THERE ARE THREE PHONE NUMBERS AND THEY ARE NOT INTERCHANGEABLE: (909) 488-4668 for permitting questions, (909) 303-1786 to share information about a scheduled inspection, and (909) 477-2710 for questions about inspections or their timeframes. Two of the three are about inspections and they do different jobs.
- IN-PERSON HOURS ARE MONDAY TO THURSDAY, 7:00 am to 4:30 pm - an early start and an early finish compared with most counters in this corpus.
- FRIDAY IS SIMPLY ABSENT FROM THE PAGE, AND THAT IS NOT THE SAME AS CLOSED. A control read confirmed the word "Friday" does not appear anywhere on the Building & Safety page. The city lists Monday to Thursday and says nothing about the fifth day. This record declines to infer a closure the city has not stated - unlike Fontana, which says "Closed Every Friday" in terms.
- NO FEE SCHEDULE AND NO PLAN-REVIEW TURNAROUND ARE RECORDED HERE, because neither was published on the pages read. The city maintains an Online Permit Center and a Daily Inspection Schedule; neither was opened for this record, so nothing is asserted from them at second hand.
