Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
For complete accepted plan submittals, the County currently reports an average review time of approximately 8-10 weeks because of the January 1, 2026 code-cycle transition, with a temporary increase expected to decrease. The initial agency-routing stage generally allows two to three weeks.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.

Submit a separate online inspection request for each permit. Requests received before 7:00 a.m. generally receive same-day inspection when it is the permit's route day; later requests move to the next available route day. South County Routes 1 and 5 run Monday, Wednesday, and Friday; North County Routes 2, 3, and 4 run Tuesday and Thursday. Call (530) 841-2100 after 8:30 a.m. for an estimated AM/PM window, or use the inspection-only line (530) 842-8270. Work requiring a permit must remain accessible and exposed until approved.
Effective January 1, 2026, the County lists the 2025 California Building Administrative Code (Title 24 Part 1); California Building Code (Part 2); California Residential Code (Part 2.5); California Electrical Code (Part 3); California Mechanical Code (Part 4); California Plumbing Code (Part 5); California Energy Code (Part 6); California Wildland-Urban Interface Code (Part 7); California Historical Code (Part 8); California Fire Code (Part 9); California Existing Building Code (Part 10); California Green Building Standards Code (Part 11); California Referenced Standards Code (Part 12); plus referenced 1997 Uniform Housing, Abatement of Dangerous Buildings, Administrative, and Sign Codes and Titles 8, 19, 20, 24, and 25 of the California Code of Regulations. The County's applications page lists exemptions including one-story detached accessory structures up to 120 sq. ft. with no electrical, plumbing, or mechanical work; fences up to 6 ft.; retaining walls up to 4 ft. measured from the bottom of the footing unless supporting a surcharge; grade-supported water tanks up to 5,000 gallons with a height-to-width/diameter ratio no greater than 2:1; sidewalks and driveways; painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work; prefabricated pools less than 24 inches deep; swings and playground equipment; wall-supported window awnings projecting no more than 54 inches; and unattached decks up to 200 sq. ft. and 30 inches above grade that do not serve a required exit. Other County approvals, design/preservation rules, and utility permits may still apply.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
