Application Process

1. Confirm jurisdiction and local land-use requirements first. For projects inside Gridley city limits, Butte County directs applicants to contact the City of Gridley Planning Department for land use and setback review before plan submittal.
2. Prepare the application package. Butte County's electronic plan review instructions require a completed DBP-01 building permit application, one full plan set PDF, and separate supporting PDFs such as structural calculations, soils reports, energy documents, and truss calculations as applicable.
3. Submit the package through Accela Citizen Access, or submit by email or in person if needed. The county's portal page says online applications, payments, and inspection requests can be completed after creating a public user account, and applications may also be submitted in person or by email to dsbuilding@buttecounty.net.
4. Pay plan review fees when billed. Butte County states plan review does not begin until the required fee payment is made.
5. Respond to plan review comments and resubmit complete revised PDFs. The county requires response letters with each resubmittal and wants revisions clouded and dated.
6. Obtain permit issuance after approvals, fees, and signatures are complete. Butte County sends the approved plan set electronically after all applicable fees are paid and permit documents are signed.
7. Keep approved plans on site and schedule inspections as work progresses through the portal, by phone, in person, or by email. Final inspection is needed to close the permit.

Typical processing time: As of March 21, 2026, Butte County's Building page shows plans being checked from about 3 weeks ago for single-family, commercial, mobile home, accessory, and nonresidential or ground-mounted solar reviews, with re-checks about 2 weeks ago. The county's adopted Housing Element also describes initial building permit review as typically 2 to 4 weeks, with later correction reviews often 1 to 3 weeks.

General Requirements

Butte County states the Building Division administers the permitting, plan review, and inspection process to enforce state and county building codes. County permit checklists state permits are required when buildings are constructed, altered, or improved, and Gridley's site-specific materials show that city grading or site-work permits are also required for grading and utility or site work within Gridley. In practice, building permits for structures and vertical construction are handled through Butte County; city planning, zoning, and some site-development permits are handled through Gridley.

Required Documents

• DBP-01 building permit application
• Full construction plans
• Site plan
• Structural calculations if engineered
• Title 24 energy documents
• Truss calculations
• Soils report if applicable
• Flood documentation if applicable
• Sewer district approval if applicable
• Owner-builder or agent authorization forms when relevant
• Gridley planning forms such as grading, fence, sign, encroachment, site development, or other local permits depending on scope

Permit validity

Butte County's current expiration handout says issued building permits expire 1 year from issuance. If work has begun and at least one inspection occurred in the previous year, the permit may qualify for renewal if renewed within 30 days of expiration. The same handout says unissued building permit applications expire 1 year from application date if there is no activity or progress. A county foundation-permit declaration also states a permit expires if work is not commenced or is suspended or abandoned for 180 days; applicants should confirm which expiration rule the county is applying to the specific permit type.

Building code

As of March 21, 2026, Butte County's Building and Plan Check pages point applicants to the 2025 California Building Standards Code set and state that permit applications submitted after the county's posted cutoff are reviewed under the 2025 Building Standards Codes. Because Gridley contracts building permit administration to Butte County, those county-administered permits should be reviewed under the same 2025 state code cycle unless a city-specific local amendment applies.

Owner-builder

Butte County publishes owner-builder guidance warning that owner-builders assume direct legal and financial responsibility. The county distinguishes owner-as-worker, owner-as-contractor, and owner-as-employer, and warns that using unlicensed contractors or uninsured workers can create substantial liability.

Contractor requirements

Butte County's permit materials are built around licensed-contractor or homeowner submittals. The county links directly to CSLB contractor search and its owner-builder guidance tells applicants to use California licensed subcontractors if they are acting as owner-builder or general contractor.

Fees

Minimum permit fee

No single universal minimum building permit fee is clearly published for all permit types in the county materials reviewed. The county does state that fee estimate requests carry a minimum charge of 0.5 hours at the current Building Division hourly rate.

Plan check fee

Plan review begins only after the county's billed plan review fee is paid. The 2025 fee schedule lists expedited plan check at $222/hour and supplemental plan check at $167/hour; many permit types also embed plan review costs into the published building fee schedule.

Permit fee formula

Mixed. The 2025 fee schedule uses flat fees for many permit types and unit-based schedules for others; the county also warns that total permit costs can include additional fees from other departments, impact fees, drainage fees, school fees, parks fees, fire, environmental health, and public works depending on project type and location.

Reinspection fee

Supplemental inspection fee $156/hour; call-out fee $203/hour with 4-hour minimum.

Penalty (no permit)

Building permit investigation fee 2x permit fee; failure-to-final investigation fee $452.

Payment note

Butte County accepts online payments through the Accela portal, and also says payments may be made in person or by mailed check to 7 County Center Drive, Oroville, CA 95965.

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

Work That Does NOT Require a Permit

• One-story detached accessory structures not over 120 square feet, where allowed by the applicable California code and local zoning
• Fences and retaining walls only where they remain within the applicable state-code exemption thresholds and do not trigger local planning or site requirements
• Finish work such as painting, papering, tiling, carpeting, cabinets, countertops, and similar cosmetic work
• Certain minor electrical, mechanical, and plumbing ordinary repairs that remain within California code exemption language

Important: Exemption from a building permit does not waive zoning, planning, grading, encroachment, floodplain, fire, utility, or other local approvals. This is especially important in Gridley because the city retains planning and zoning authority and separately publishes local forms for grading permits, fence permits, sign review, encroachment permits, and site development applications. Applicants should confirm both Butte County building exemptions and City of Gridley local permit triggers before proceeding.

Inspections

How to Schedule

• Accela Citizen Access (online)
• (530) 552-3699 (phone)
• dsbuilding@buttecounty.net (email)

Time windows

Butte County publishes daily inspection schedules online and says the posted inspection time is an estimate; inspectors may arrive up to 1 hour earlier or 1 hour later. The Building page says the online inspection schedule shows the 2-hour inspection window and inspector name.

Typical inspection sequence: County materials show common inspection stages including setbacks, footing or foundation, under-slab or underfloor plumbing, underground utilities, rough framing, rough mechanical, rough plumbing, rough electrical, insulation or specialty items where applicable, and final inspection. The precise sequence depends on project type.
