Summary

Rialto bars anyone from erecting, altering, moving, repairing, demolishing or grading any building or structure without first obtaining a permit from the Building Official. The rule sits in Rialto Municipal Code Section 15.08.030, which adopts the 2025 California Building Code and amends CBC Section 105.1 to spell out the local permit trigger.

[A] CBC Section 105.1 Required is amended to read as follows: No person may erect, construct, enlarge, alter, repair, move, improve, remove, connect, convert, demolish, or equip any building, structure, or portion thereof, perform any grading, or cause the same to be done, without first obtaining a permit for each such building, structure, grading, or landscaping from the building official.

Full Breakdown

Rialto adopted the 2025 California Building Code by reference under Ordinance No. 030. 1 (Required) to state that no person may erect, construct, enlarge, alter, repair, move, improve, remove, connect, convert, demolish, or equip any building, structure, or portion thereof, or perform any grading, without first obtaining a permit from the Building Official. 3, separately makes it unlawful to own, use, occupy or maintain an 'Unpermitted Structure,' defined as anything built, altered or left with expired, unfinished permitted work. 2 deletes the exception that had exempted lower fences, citing seismic and high-wind conditions plus ember-resistance for combustible fencing materials.

1 sets a reinstatement fee if a plan check expires: 25 percent of the original plan check fee if renewal is sought within a year, 50 percent after a year. 2 applies the same 25/50 percent scale to expired permits. 8 vests permit ownership in the property owner and requires a new Owner-Builder Declaration and deed copy when title transfers. 1 caps permit fee refunds at 50 percent, must be requested in writing within 180 days of payment, and bars any refund once construction has started.

7 authorizes a reinspection fee whenever work is not ready or corrections are outstanding. 5 bars occupancy until the Building Official issues the permit, completes inspections, and issues a certificate of occupancy.

Violations & Fines

Under CBC Section 114.5, work commenced without a permit triggers a mandatory special investigation before any permit can issue, and the resulting unpermitted structure is independently unlawful under CBC Section 105.1.3. Violations of the Rialto Municipal Code are prosecuted under Chapter 1.16: a misdemeanor carries up to a $1,000 fine and six months in jail, while an infraction escalates from $100 (first offense) to $200 (second, within two years) to $500 (each additional violation), with every day of continuing violation counted as a separate offense.

Frequently Asked Questions

Do I need a permit to build a fence in Rialto?
Yes, for any fence, including ones under 7 feet. Rialto's amendment to CBC Section 105.2 deletes the standard exception for shorter fences because of local seismic activity, high wind speeds, and the need for noncombustible material to resist ember spread during wildfires.
What happens if I start construction before getting a permit?
The Building Official must order a special investigation under CBC Section 114.5 before any permit can be issued, and the structure is separately classified as an unlawful 'Unpermitted Structure' under CBC Section 105.1.3 until it is brought into compliance.
Can I get my permit fee back if I cancel my project?
Only if construction has not started. CBC Section 109.6.1 allows the Building Official to refund up to 50 percent of the fee, but you must file a written request within 180 days of payment, and no refund issues once the job has broken ground.
What if my building permit expires before the project is finished?
CBC Section 105.5.2 lets you request renewal in writing, but you pay a reinstatement fee: 25 percent of the original plan check fee if it has been under a year, 50 percent if over a year, and any new plans must meet the current code cycle.
