Building department

Address: 303 W. Commonwealth Ave., Fullerton, CA 92832
Phone: 714.738.6300 (City); (714) 738-6543 (Voice Permits automated inspection line, 24 hours)
Email: NOT PUBLISHED on the pages read for this record; no divisional mailbox appeared in the page source.
Office hours: "Monday - Thursday 7:30 AM - 5:30 PM" and "Every other Friday 7:30 AM - 4:30 PM" - AND NOTE THAT THE ALTERNATING FRIDAY IS AN HOUR SHORTER, not merely a day that happens or does not happen. WHICH Friday is the open one is not stated on the pages read. These are also the CITY'S published hours rather than counter hours stated by Building and Safety itself, so this record does not claim the permit counter keeps them; call 714.738.6300 if the difference matters to your trip.

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.

THE RULE IS STATED IN BOTH DIRECTIONS, WHICH ALMOST NO RECORD HERE DOES: "The 2025 California Building Codes and City of Fullerton Amendments are enforceable for all residential and non-residential construction projects submitted on or after January 1, 2026. Show full textShow less
THE RULE IS STATED IN BOTH DIRECTIONS, WHICH ALMOST NO RECORD HERE DOES: "The 2025 California Building Codes and City of Fullerton Amendments are enforceable for all residential and non-residential construction projects submitted on or after January 1, 2026. Projects submitted prior to January 1, 2026 shall comply with the 2022 Codes." Most cities publish the new cycle and leave the old one to be inferred; Fullerton says what governs on either side of the line.
THE FULL 2025 SET IS ENUMERATED: California Building Code, Residential Code, Electrical Code, Mechanical Code, Plumbing Code, Energy Code, Historical Building Code, Fire Code, Existing Building Code and Green Building Standards Code.
AND THE DIVISION CONFIRMS THE CYCLE IN ITS OWN WORDS ELSEWHERE: "We are currently under the provisions of the 2025 Edition of the California Building Standards Codes Cycle."
Health & Safety Code 18938(b) provides that building standards in the California Building Standards Code "shall apply to all occupancies throughout the state and shall become effective 180 days after publication."

Permit types & fees

Building Permit
Fullerton publishes two things better than most of this corpus: a code rule that states what governs on both sides of the cycle boundary, and a set of local design criteria detailed enough to design from. Inspections run on a 24-hour automated telephone system.

Fullerton's permit history isn't searchable here yet

This page covers what the permit requires. What we don't have for Fullerton 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 Fullerton lands. Privacy.

Tips & gotchas

THE CODE RULE IS STATED IN BOTH DIRECTIONS AND THAT IS RARER THAN IT SOUNDS: projects submitted on or after 1 January 2026 are on the 2025 codes, and "Projects submitted prior to January 1, 2026 shall comply with the 2022 Codes." Most records in this corpus publish only the incoming cycle, leaving anyone with an older live application to guess. Fullerton removes the guess.
FULLERTON NAMES THE LEGAL GROUND FOR ITS AMENDMENTS, WHICH NOTHING ELSE IN THIS CALIFORNIA BATCH DOES: the state codes "have been amended by the City of Fullerton to address local topographic, climatic, and/or geologic conditions, and to include provisions pertaining to the administration of these codes." That phrase is the express-findings category Health & Safety Code 17958.7 requires before a California city may modify the state code. Every record in this corpus cites that requirement; this is the first city observed stating that its amendments rest on it.
THE LOCAL DESIGN CRITERIA ARE DETAILED ENOUGH TO DESIGN FROM, and more granular than anything else here: "Seismic Design Category D, E or F as determined by USGS Maps and CBC Chapter 16"; basic wind speeds given for all four risk categories - "Risk Category I: 89 mph, Risk Category II: 95 mph, Risk Category III: 102 mph, Risk Category IV: 106 mph"; and "Climate Zone 8". Sunnyvale publishes three such values; Fullerton publishes six.
AND NOTE THAT THE SEISMIC CATEGORY IS A RANGE, NOT A VALUE: "D, E or F as determined by USGS Maps and CBC Chapter 16". A city that published a single SDC would be easier to quote and less correct - the category depends on the site, and Fullerton says so rather than flattening it.
THE INSPECTION CUT-OFF IS MIDNIGHT, THE LATEST IN THIS CORPUS BY SEVERAL HOURS: "Calls placed before midnight will be placed on the following working day's schedule." Compare Salinas at noon for a morning slot, Lancaster and Fremont at 2pm, Oceanside at 3:30pm, Oxnard at 4pm. An evening decision to book tomorrow works here and nowhere else in this batch.
THE BOOKING SYSTEM CAPTURES A GATE CODE - "Enter a gate code (if applicable)" - and it is the only one here that does. Salinas publishes the same problem from the opposite end, warning that "Inspectors are not authorized to open gates or access points" and leaving the applicant to solve it. One city fixed it in the form; the other documented it as a risk. Both are honest; only one removes the failure.
THE ALTERNATING FRIDAY IS SHORTER, NOT JUST INTERMITTENT: "Monday - Thursday 7:30 AM - 5:30 PM" against "Every other Friday 7:30 AM - 4:30 PM". An hour comes off the end of the day on the Friday that is open. Pasadena and Vallejo also run alternating Fridays, and both keep the same hours on them - this is a third variation on the pattern.
WHICH FRIDAY IS OPEN IS NOT PUBLISHED on the pages read, which puts Fullerton with Vallejo rather than with Pasadena. Pasadena publishes a Permit Center Calendar that answers it; here and in Vallejo the alternating schedule cannot be resolved from the city's own pages.
COMPLETENESS IS DEFINED BY A CODE SECTION, NOT BY THE COUNTER: "the submittal documents must contain all information as required per California Building Code Section 107." Where a city cites the section, a rejection is checkable against a published standard rather than being a matter of who is at the desk.
THE SUBMITTAL LIST IS EXPLICITLY NOT A CHECKLIST TO SATISFY IN FULL: "not all items may be necessary based on the proposed scope of work. Please speak with the Building Division to clarify if an item is necessary for submittal." Preparing every listed sheet for a small job is wasted drawing.
NO DIVISIONAL EMAIL IS PUBLISHED on the pages read - the routes are the automated inspection line on (714) 738-6543 and the city switchboard on 714.738.6300.
