Your new hood system will sit idle and inspections will be blocked until you have a Hood/Exhaust Ventilation System Permit from the City of San José Planning, Building & Code Enforcement Division, also called a mechanical exhaust permit. Key facts:

Manual entry or document upload required
You need a Hood/Exhaust Ventilation System Permit in San Jose because state and local law requires a city inspector to approve any permanent mechanical system that removes grease, smoke, or combustion gases from your kitchen before you can legally use it. The primary authority is the 2022 California Building Code (CBC), specifically the Mechanical Code (Title 24, Part 4) and the California Fire Code, as locally amended and enforced by the San Jose Department of Planning, Building, and Code Enforcement. This permit ensures your system meets minimum safety standards for fire prevention, air quality, and structural support, as outlined in San Jose's local amendments to these state codes. Without this stamped approval, your installation is considered non-compliant from day one.
The consequences of installing or operating a hood system without this permit are immediate and costly. Based on ApronPrep's analysis of enforcement actions in Santa Clara County, common penalties include:
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, the City of San Jose now requires all permit applications for mechanical systems, including hoods, to be submitted through its online portal, eliminating the previous option for in-person paper submissions at the permit center.
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required if cooking operations produce grease, smoke, or steam, as per San Jose Municipal Code Section 15.04.100 and the California Mechanical Code. |
| Bar / Nightclub | Required | Required if the facility includes a kitchen preparing hot food; bars without kitchens may be exempt, but verification with the Building Division is needed. |
| Food Truck | Required | Required; mobile food facilities are regulated under California Health & Safety Code and need an approved system as part of the Mobile Food Facility Permit. |
| Coffee Shop / Café | Not Required | Not required if only using equipment like espresso machines that do not produce grease-laden vapors, per California Mechanical Code classification. |

See Full Requirements →Enter 'Owner' if you are the property owner or restaurant owner filing on your own behalf, or 'Contractor' if you are the licensed contractor performing the work and filing for the permit.
COMMON MISTAKE: Entering a business name (e.g., 'ABC Restaurant') or an ambiguous term like 'Applicant'; review staff will reject the application for an unclear applicant role.
Enter the full legal name of the property owner as it appears on the deed or property tax bill for the installation address.
COMMON MISTAKE: Listing the business operator or tenant name instead of the legal property owner; this mismatch with the ownership authorization document is a top cause for rejection.
Provide a direct, working phone number for the property owner, typically a mobile number or office line where they can be reached during business hours.
COMMON MISTAKE: Providing a disconnected number or the phone number of the contractor; this can delay the permit if the city needs to verify ownership details.
Enter a valid email address for the property owner, which the city will use for official permit correspondence and status updates.
COMMON MISTAKE: Using the contractor's or architect's email address; the city requires direct owner contact for legal notifications related to the property.
Enter the complete physical street address of the restaurant or commercial kitchen where the ventilation system will be installed, including suite or unit number if applicable.
COMMON MISTAKE: Providing a mailing address, P.O. Box, or corporate office address instead of the exact installation site; this causes immediate rejection as it's needed for on-site inspection scheduling.
Describe the document you are attaching to prove authorization, such as a 'Grant Deed,' 'Property Tax Bill,' or a notarized 'Authorization Letter from Owner' if you are not the owner.
COMMON MISTAKE: Writing 'See attached' or leaving blank; you must explicitly name the document type (e.g., 'Notarized Letter from John Smith') so reviewers can verify it against your submission.
Enter the exact, registered business name of the licensed mechanical or sheet metal contractor who will perform the hood installation, as it appears on their state contractor's license.
COMMON MISTAKE: Using a DBA ('Doing Business As') name that does not match the state license; the city verifies this against the CSLB database and will reject applications for mismatches.
Provide the full name of the primary point of contact at the contractor's business for this project, such as the project manager or license holder.
COMMON MISTAKE: Listing a generic title like 'Project Manager' without a specific name; the city needs a named individual to contact for plan review questions and inspections.
Enter the direct business phone number for the contractor contact person, which must be operational for inspection coordination and plan review clarifications.
COMMON MISTAKE: Providing a personal mobile number that is frequently unavailable; this can delay inspections and add days to your project timeline.
Provide a professional email address for the contractor contact person, which will be used by the city to send approved permits, inspection results, and deficiency notices.
COMMON MISTAKE: Using an incorrect or outdated email; missed communications about required corrections can lead to permit expiration before work is approved.

Submitting a generic schematic instead of a plan scaled to your specific cooking equipment and hood model is the top cause of review rejection. Plans must show the exact make/model of the listed hood, the BTU output of all appliances under it, and the calculated required CFM. For example, listing a 1,200 CFM hood when your combi-oven's manual requires 1,500 CFM for proper capture will fail. This mistake adds 2–3 weeks as you must re-draw plans and resubmit.
Omitting the fire suppression system's UL number, the installer's license number, or the location of the manual pull station triggers an automatic correction notice from the San José Fire Department. The permit application must prove the suppression system is appropriate for the fuel type (e.g., wet chemical for grease) and is installed by a licensed contractor. Forgetting this detail stalls the fire department's parallel review, delaying your overall permit by 10-15 business days.
Failing to account for make-up air, or proposing an inadequate source, violates California Mechanical Code § 401.3. The application must include a calculation showing how you will replace the air being exhausted (typically 80-100% of exhaust CFM). Simply stating 'from dining area' is insufficient; you must specify the size and location of dedicated transfer grilles or a dedicated make-up air unit. This oversight requires a full re-submission of the mechanical plans, adding 3-4 weeks to your timeline.

Confirm you are the legal property owner or possess the appropriate California State Contractor's License (typically Class C-38 - Refrigeration or related specialty). Non-licensed homeowners cannot apply for this commercial mechanical permit on behalf of a business. Gather your state license number and business registration documents.
If applying as a contractor, you must have a current City of San José Business Tax Certificate. Apply or renew through the City's Tax Services Unit online. Your application will be rejected without this certificate. Processing a new certificate can take 3-5 business days.
Check the SJPermits.org portal under 'Mechanical Permits' or contact the City of San José Planning, Building & Code Enforcement Department at (408) 535-3555. Complex commercial kitchen hoods often require a full plan review, which may not be available for instant online issuance.

See All RequirementsThe City of San José does not publish a standard processing timeline for this permit. Contact the Planning, Building & Code Enforcement Department directly for the expected processing timeline, as it can vary based on project complexity and plan review workload. A typical project requiring a Building Permit may experience longer review times.
Government filing fees are not published as a standard range for this specific permit. Per the City of San José fee schedule, plan review and permit costs are typically calculated based on the valuation of the mechanical work. You must contact the Planning, Building & Code Enforcement Department for a fee estimate prior to submitting your application. Not legal advice — verify all costs with the city.
No, hood/exhaust ventilation system permits are not transferable. Permits are issued for a specific system at a specific address based on the approved plans. If you relocate your restaurant or equipment, you must apply for a new permit at the new location, which will require a new plan review and Building Permit application if structural modifications are needed.
This is typically a one-time permit for the initial installation and does not require periodic renewal. However, if you modify or replace the system, you must obtain a new permit. The system will be subject to ongoing compliance through regular fire safety inspections conducted by the local fire authority, which are separate from the initial permit process.
A city inspector will verify the installation matches the approved plans and complies with the California Mechanical Code and California Fire Code. They will check for proper clearance from combustible materials, correct duct sizing and routing, secure mounting of the hood, and proper termination of the exhaust. The inspection must be passed before the system can be used for commercial cooking.
