General Requirements

The Building Division states it administers permits, plan review, and inspections to enforce state and county building codes and ordinances. For residential projects, the County's submittal checklist says permits are required when buildings are constructed, altered, or improved. Work exempt from permits is listed separately in County form DBP-20.

Required Documents

• DBP-01 building permit application
• Site plan
• Complete plan set
• Structural calculations when applicable
• Title 24 energy documents
• Special inspection forms when applicable
• Additional agency approvals as required
• Proof of current contractor license and workers' compensation insurance at permit issuance for contractor-filed permits

Permit validity

Issued building permits expire 1 year from issuance. If work has begun and at least one inspection occurred in the prior year, the permit may qualify for renewal if renewed within 30 days of expiration. Applications that are filed but not issued expire 1 year after application if there is no activity and are not renewable.

Building code

Effective January 1, 2026, applications submitted after December 31, 2025 at 3:00 pm are reviewed under the 2025 California Building Standards Codes, including the California Building, Residential, Mechanical, Electrical, Plumbing, Energy, Fire, Green, Historical, and Existing Building Codes. County ordinances and local requirements also apply.

Owner-builder

Owner-builders may apply, but the property owner must complete the County's owner acknowledgment form before issuance. County guidance explains owner-as-worker, owner-as-contractor, and owner-as-employer risks and responsibilities.

Contractor requirements

Licensed contractors or their authorized agents may apply. If a contractor is using an agent, the County requires a contractor authorization letter including the contractor's license number. For contractor-issued permits, proof of current contractor license and workers' compensation insurance is required at issuance.

Fees

Minimum permit fee

No single universal minimum building permit fee is separately published. The County instead uses permit-type base or flat fees and hourly charges. For fee estimates, the County says the minimum estimate charge is 0.5 hours at the adopted Building Division fee-estimate rate.

Plan check fee

Plan check is generally built into the permit fee schedule by permit type. Additional plan-check-related charges include expedited plan check at $222/hour and supplemental plan check at $167/hour.

Permit fee formula

Primarily permit-type flat or base fees with add-on amounts by square footage or unit, plus surcharges and hourly charges for certain services. The County also warns that other departments and impact-fee programs may add project-specific fees.

Reinspection fee

Supplemental inspection fee is $156/hour.

Penalty (no permit)

Code enforcement lists a building permit investigation fee of 2x permit fee and a failure-to-final investigation fee of $452. Permit renewal fee is $134 for up to 1 year.

Payment note

Online payments can be made through ACA after account creation. The County also accepts payment in person or by mailed check to 7 County Center Drive, Oroville, CA 95965.

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