Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

(707) 784-6765; 24-hour inspection request line (707) 784-4750
Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
Solano County Department of Resource Management - Building & Safety Services is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact (707) 784-6765; 24-hour inspection request line (707) 784-4750.
N/A; the County explains that plan review begins after electronic submittal and payment of plan-check fees, but does not publish a standard review duration. Timing varies by project type, completeness, corrections, and agency requirements.
Call the 24-hour inspection request line at (707) 784-4750 and leave the permit number, job-site address, inspection type, and callback number. Requests made before 3:00 p.m. are scheduled for the following business day; later requests are scheduled two business days later. Specific times cannot be requested. Keep approved plans and the permit card on site, and do not cover work before inspection.
Solano County's current requirements page lists the 2025 California Building Code, 2025 California Residential Code, 2025 California Mechanical Code, 2025 California Electrical Code, 2025 California Plumbing Code, 2025 California Fire Code, 2025 California Energy Code, 2025 California Green Building Standards Code, 2025 California Wildland-Urban Interface Code, and 2025 California Existing Building Code, with applicable County ordinances and fire-hazard-severity-zone requirements for unincorporated areas. Under the County's CBC Section 105.2 guidance, exemptions include one-story detached accessory sheds/storage buildings/playhouses up to 120 sq. ft. with no utilities; fences up to 6 ft.; oil derricks; retaining walls up to 4 ft. measured from footing bottom unless supporting surcharge or certain liquids; grade-supported water tanks up to 5,000 gallons at no more than a 2:1 height-to-width/diameter ratio (piping and electrical still require permits); qualifying sidewalks and driveways no more than 30 inches above grade; painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work; temporary stage sets; qualifying above-ground prefabricated pools under 24 inches deep and 5,000 gallons; agricultural/nursery shade-cloth structures without service systems; residential playground equipment; qualifying wall-supported window awnings projecting no more than 54 inches; and movable fixtures/cases/racks/counters/partitions no higher than 5 ft. 9 in. Commercial or industrial counters still require permits.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
