How long do building permits last in Ventura County?
In Ventura County, a building permit application expires 12 months after the application date if the permit has not been issued. In many cases, the county may grant an extension of up to six additional months if requested before the application expires.
Once a permit is issued, it typically becomes void if work does not begin within 12 months, or if construction is suspended or abandoned for 180 days or more after it has started. Ventura County may approve written extensions for up to 180 days at a time when there is good cause.
Ventura County trade permits
Plumbing permits
Ventura County provides a separate plumbing permit fee schedule and inspection process through the Building and Safety Division. Depending on the scope of work, plumbing permits may be issued as standalone permits or included as part of a combination building permit.
Electrical permits
Ventura County also publishes a separate electrical fee schedule. Electrical work can be part of a combination permit or issued separately depending on the project.
HVAC permits
Ventura County’s mechanical permit schedule covers HVAC systems, ducts, equipment, and related residential and nonresidential mechanical work.

How to get a building permit in Ventura County
Step 1: Prepare your plans and documents
As of January 1, 2026, all new Ventura County building permit applications must comply with the 2025 California Building Standards Code (Title 24) and the local Ventura County amendments.
- All plans must be high-resolution PDFs, asVentura County no longer accepts paper plans for initial submittals
- Any structural changes, new construction, or complex electrical/mechanical systems require the seal of a California-licensed Architect or Engineer
- Building and Safety provides specific "B-Series" handouts (e.g., B01 for Residential, B50 for Foundations) that dictate exact plan requirements
Note: Use B&S permit processing checklist to get more information on other documents required.
Step 2: Submit your application online
The VC Citizen Access Portal is the mandatory entry point for all unincorporated areas.
- Registration: You must create an account
Instant permits: For simple "like-for-like" replacements (water heaters, HVAC change-outs, re-roofing), use the "Express Insta-Permits" option for immediate issuance - Filing fee: A non-refundable application fee (approx. $71.00 for single permits) is due at the time of upload
Step 3: Plan review
Under the "March 1 Streamlining Process," the applicant is no longer the "messenger" between county agencies.
- Internal coordination: Once you submit to Building and Safety, they coordinate reviews with Planning/Zoning, Public Works, Fire, and Environmental Health internally
- The “30-day shot clock” (AB 253): If your project is a residential building with 1–10 units, the County must provide an estimated review timeframe. If they cannot finish the review in 30 days, you now have the legal right to hire a private professional plan checker to finish the job
- Timeline: Initial reviews generally take 3–4 weeks, while subsequent "re-checks" are aimed at 7–10 business days
Step 4: Pay final fees and receive your permit
Before the permit is "Activated," you must settle the remaining balance. Upon payment, you will download your Issued Permit, Inspection Record Card, and Approved Plans. You are required to have a printed copy of the approved plans at the site at all times.
Step 5: Begin work and schedule inspections
Get started on your project, and don’t forget to schedule required inspections. More on that below.
Permit inspections in Ventura County
Ventura County schedules inspections through the Building and Safety Division. Active construction inspections can be requested through the county’s automated system, which allows permit holders to schedule, cancel, reschedule, and check inspection results.
These inspections commonly include:
- Foundation & footings: Must be inspected after forms and rebar are set, but before concrete is poured
- Slab & underfloor: Inspection of plumbing, electrical, and mechanical lines that will be under a concrete slab or floor joists
- Roof sheathing & pre-wrap: After the roof deck and weather barriers are installed but before final roofing material
- Rough-ins (combo): The most critical phase. Includes framing, plumbing, mechanical, and electrical
- Note: The building must be "dried in" (roof on, windows in) before rough electrical is approved
- Lath & drywall nailing: After the backing is on but before plaster or tape/mud is applied
- Finals: Once all fixtures are set and the project is 100% functional
How to schedule an inspection
Ventura County uses an automated text system for all active construction projects.
- The number: Text to 844-405-1846
- The process:
- Text SCHEDULE
- Enter your Permit Number (e.g., C-26-XXXX) without dashes
- Enter the 3-digit Inspection Code (e.g., 125 for Rough Mechanical on a Combo permit)
- Select your date (MM/DD format)
- The system will confirm the request. You will receive a text the morning of the inspection (usually by 8:30 AM) with a 2-hour arrival window
- Alternative: You can still use VC Citizen Access or call the Ventura office at (805) 654-2791 or Simi Valley office at (805) 582-8063
The 10-day rule
As of January 1, 2026, California law (AB 1308) mandates that the county building department must conduct inspections for new residential construction (1–10 units) within 10 business days of receiving notice that the work is complete.
If the county misses this 10-day window, it is considered a violation of the Housing Accountability Act, which gives builders additional legal leverage to finalize their projects.
Inspection day requirements
To avoid failed inspections or delays, make sure your job site is properly prepared:
- Access: If the inspection area is indoors or behind a locked gate, someone must be on-site to provide access
- Safe access equipment: If roof or attic access is required, the contractor is responsible for providing safe access (such as a ladder) that meets safety standards
- Approved plans on-site: A printed set of approved plans and the inspection record card should be available on-site for the inspector’s reference
If the work is incomplete, inaccessible, or not ready, the inspection may be rejected and require rescheduling.
Closing out your permit
- Final sign-off: A project is only complete once all required inspections have been approved, including building, plumbing, mechanical, and electrical (if applicable)
- Certificate of Occupancy (CO): Required for new buildings and for projects involving a change in use before the space can be occupied
- Agency clearances: Depending on the project, additional approvals (such as air quality or fire) may be required before final sign-off
- Temporary occupancy: In limited cases, temporary occupancy may be granted before final approval if the building is safe and meets minimum requirements
