When a permit is required
Permit triggers and exempt work for Plumas County
Plumas County uses permit applications for new single-family dwellings and duplexes, additions and remodels, garages, decks and porches, structural repairs, reroofing, demolition, grading, fire-safe driveways, electrical, plumbing, mechanical, signs, photovoltaic systems, temporary structures, EV charging stations, and other miscellaneous construction. The county also posts a no-fee application for storage sheds or accessory buildings under 200 square feet and certain agricultural buildings, so applicants should not assume small detached structures are permit-exempt locally without confirming with Building Services.
Ordinary finish work such as painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work may be exempt under the California state code adopted by the county.
Small detached accessory structures should not be treated as permit-exempt without checking first, because the county publishes a no-fee permit application specifically for one-story detached accessory structures used as tool sheds, wood sheds, playhouses, or similar uses when the floor area does not exceed 200 square feet.
Applicants should review the currently effective California Building Code and California Residential Code exemption sections for trade-specific minor work, because Plumas states it follows the state code cycle without local amendments to the listed codes.

- Building code
- Plumas County states in its adopted Housing Element that its ordinance is written to automatically adopt new state code editions without a county ordinance update every three years and that it has not made local amendments to the listed state building codes. Based on that county statement and the California Department of Housing and Community Development's published notice that the 2025 California Building Standards Code became effective January 1, 2026, Plumas County should now be enforcing the 2025 California Building Standards Code cycle for current applications, but applicants should confirm any project-specific local policies with the Building Department.
- Permit validity
- A building permit application expires 12 months after filing unless issued or extended. Once issued, a building permit expires 24 months after issuance and becomes invalid if work does not commence within 180 days or if work is suspended or abandoned for more than 180 days. The county may grant written 180-day extensions, generally with an administrative fee of $66.25 per extension under the published policy.
- Owner-builder
- The county application package includes owner-builder declarations and cautionary notices. Owner-builders must sign the required declarations, and if they hire workers who are not properly licensed contractors with their own workers' compensation coverage, they may become the employer responsible for insurance and labor-law compliance.
- Contractor requirements
- The permit application requires either a licensed contractor declaration or a valid owner-builder exemption statement. County forms state any licensed contractor must have a current active California contractor license, must provide the license number on permits, and must maintain workers' compensation coverage where required.
