Application Process

1. Confirm the property is within Oroville city limits and determine whether the work needs a permit; the city lists common permit-triggering work and permit-exempt work on its Building Division pages.
2. Create an account in the Oroville Civic Access portal. The city states that effective November 5, 2024, applications, permits, licensing, and certificates are available online.
3. Submit the general building permit application and required plans or documents. For residential plan check, the city requires a completed application, 3 plan sets, 3 site plans, and supporting calculations or documents as applicable.
4. Pay plan review and technology-cost-recovery fees at submittal. The city notes a plan review fee is due at submittal and a 6% technology fee applies to permits.
5. Respond to plan review comments. Published first-review timelines range from over-the-counter review for simple projects to 10, 15, 20, or more than 20 working days depending on project type; the older public-facing permit page also says many residential plan reviews take about 10 to 15 working days.
6. After approval, pay issuance fees before permit issuance.
7. Schedule required inspections with the Building Division and keep work accessible until approved. Final approval is required before occupancy-related approvals.

Typical processing time: Over the counter for reroofs, HVAC or water-heater replacement, minor plumbing, siding or windows, minor demolition, meter replacement, and residential solar; 10-day, 15-day, 20-day, and more-than-20-day tracks are published for other project types.

Permit validity

The city's application says permit applications expire 180 days after last activity unless an extension is granted. The city's cancellation or extension form also states plan review expires if no permit is issued within 180 days, and permits expire if work is not started within 180 days or is suspended or abandoned for 180 days. Renewal is generally one-half of a new permit fee if no changes are made and the lapse is not over one year; otherwise a new full permit fee may apply.

Building code

The city's 2022 Design Criteria sheet says Oroville has adopted the 2022 California Building, Residential, Plumbing, Mechanical, Electrical, Energy, Green Building Standards, Fire, Administrative, Historical Building, Existing Building, and Referenced Standards Codes.

Owner-builder

The application includes an owner-builder declaration. Owners may claim exemption if they perform the work themselves or through employees and the structure is not intended or offered for sale, or if they contract exclusively with licensed contractors.

Contractor requirements

The permit application requires a California contractor license declaration. The residential submittal guidelines also state all contractors working within Oroville city limits must have a current City of Oroville business license and certificate of workers' compensation insurance on file, if applicable; the same applies to subcontractors.

Fees

Minimum permit fee

$177 when one inspection is required; $354 when two inspections are required

Plan check fee

General plan review is 65% of the building permit fee; miscellaneous plan review fee is $88 per half hour minimum; additional plan review due to changes, additions, or revisions is also $88 per half hour minimum.

Permit fee formula

Mixed. The FY 2025-26 schedule shows valuation-based and state add-ons such as SMIP fees (residential valuation x 0.00013; commercial valuation x 0.00028) and green-building fees ($1 per $25,000 of permit valuation), plus hourly or flat city fees. General plan review for permits requiring plan submittal is listed as 65% of the building permit fee.

Reinspection fee

Reinspection fees are listed at $177 per hour under the building-fee schedule; business-license or first-time-homebuyer reinspection is also $177 per hour minimum 1 hour.

Penalty (no permit)

Permit renewal after expiration is generally one-half of a new permit fee if eligible; if expired over one year, a new full permit fee may apply.

Payment note

The residential submittal guidelines state the city takes cash, check, money order, or credit card (Visa or MasterCard) for plan-check review fees. The applications page also states a 6% technology fee is added to all permits under Municipal Code section 17.08.130.

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