Hood/Exhaust Ventilation System Permit in San Antonio, Texas (2026)
Your final health inspection will be delayed, and your opening date pushed back, if you install commercial kitchen ventilation without first getting a Hood/Exhaust Ventilation System Permit from the San Antonio Development Services Department. This mechanical permit, also called a Type I Hood System Permit, is required before any ductwork or hood installation begins.

Why You Need a Hood/Exhaust Ventilation System Permit
The Hood/Exhaust Ventilation System Permit is mandated by San Antonio's local building and fire safety codes, specifically the city's Building Construction Code (2021 International Building Code, 2021 International Mechanical Code, and 2021 International Fire Code with local amendments) and the Texas Accessibility Standards. These are administered by the City of San Antonio's Development Services Department (DSD). The requirement is not optional; it's a core component of the plan review for any new restaurant build-out, major remodel, or equipment change involving commercial kitchen ventilation. The permit ensures your system design meets minimum safety standards for fire suppression, grease containment, and air quality, as verified by a city inspector.
Operating or constructing a kitchen ventilation system without this permit triggers immediate enforcement action. Based on analysis of common enforcement outcomes in San Antonio, the practical consequences include:
- Stop-work orders — All construction halts immediately, adding weeks or months to your project timeline.
- Daily fines and mandatory correction — Fines accrue for each day of non-compliance. The city may require partial or complete demolition of the unpermitted installation.
- Certificate of Occupancy (CO) denial — Your restaurant cannot legally open for business.
- Insurance and lease implications — Your property insurance may be voided for unpermitted work, and you may be in violation of your lease terms, which typically require compliance with all local codes.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of the 2026 permit cycle, San Antonio DSD now requires all mechanical permit applications, including for hood systems, to be submitted through the city's online portal (SA ePermits) with digital plans, eliminating the previous option for in-person paper submittals for initial review.
Who Needs a Hood/Exhaust Ventilation System Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required for any kitchen producing grease-laden vapors from frying, grilling, or broiling, as defined by the 2021 International Mechanical Code § 507. |
| Bar / Nightclub | Required | Required if the establishment has a kitchen preparing hot food, even with a limited menu; a standalone bar without cooking may only need a Type I hood. |
| Food Truck | Required | Required as it is a mobile food preparation vehicle, regulated under the San Antonio Fire Code and the Texas Food Establishment Rules for commercial cooking appliances. |
| Coffee Shop / Café | Not Required | Typically not required if operations are limited to equipment like espresso machines and toasters that do not produce grease-laden vapors, per IMC § 507 exemptions. |

57 of 69 auto-filledBusiness Legal Name
textEnter the exact, full legal name of the entity that owns the restaurant as it appears on your Articles of Incorporation, LLC Certificate, or assumed name certificate filed with the Texas Secretary of State.
COMMON MISTAKE: Entering the 'doing business as' (DBA) trade name here instead of the legal entity name (e.g., putting 'Mario's Pizza' when the legal entity is 'Alamo Foods, LLC') is a common reason for rejection.
DBA Name (if applicable)
textEnter the trade name the public knows your restaurant by, if it differs from your business legal name, as registered with Bexar County or the Texas Secretary of State.
COMMON MISTAKE: Leaving this blank when you operate under a DBA, or entering a DBA that is not officially registered, can cause the city to reject the application for mismatched business identity.
Business Type
selectSelect the official legal structure of your business from the provided list (e.g., Sole Proprietorship, Limited Liability Company (LLC), Corporation, Partnership).
COMMON MISTAKE: Incorrectly selecting 'LLC' when your business is a sole proprietorship, or vice versa, can invalidate your application's legal authority section.
Applicant Name
textEnter the full name of the person authorized to sign the permit application on behalf of the business, typically the owner, a managing member, or a corporate officer.
COMMON MISTAKE: Entering a name of someone without legal signing authority (e.g., a contractor or employee) will cause the city to reject the application for lack of proper authorization.
Applicant Title
textEnter the official title of the person listed as the applicant (e.g., Owner, President, Managing Member, General Partner) that matches your business's organizational documents.
COMMON MISTAKE: Using informal titles like 'Manager' or 'Chef' instead of the legally recognized title can delay the application, as it questions the signatory's authority.
Contact Phone
textEnter a direct, working phone number for the applicant or primary project contact, including area code, in a standard 10-digit format (e.g., 210-555-1234).
COMMON MISTAKE: Providing a disconnected number, a number for a different business location, or formatting it incorrectly (e.g., with parentheses) can prevent inspectors from scheduling required reviews.
Contact Email
textEnter a valid, frequently monitored professional email address for the primary contact to receive permit status updates, correction notices, and inspection schedules from the Development Services Department.
COMMON MISTAKE: Using an old, inactive, or typo-filled email address is a top reason applicants miss critical correction notices, leading to permit expiration and reapplication fees.
Facility Street Address
textEnter the complete physical street address of the restaurant where the hood and exhaust system will be installed, including suite or unit number if applicable, as recognized by the City of San Antonio for 911 addressing.
COMMON MISTAKE: Entering a mailing address, P.O. Box, or an approximate address (e.g., 'Main Street') instead of the exact, official physical address will cause an automatic rejection, as inspection routing depends on it.
City
textEnter 'San Antonio' for the city where the facility is located; do not use abbreviations or neighboring municipality names.
COMMON MISTAKE: Incorrectly entering a neighboring city like 'Leon Valley' or 'Alamo Heights' for a San Antonio address will route your application to the wrong jurisdiction, causing significant delays.
State
textEnter 'TX' or 'Texas' as required by the form's format for the state where the facility is located.

Top 5 Hood/Exhaust Ventilation System Permit Mistakes
1. Submitting Incomplete or Non-Compliant Floor Plans
Providing a generic sketch instead of a professionally drawn, scaled floor plan showing the exact hood location, all appliances underneath, and distances to walls/ceilings. The San Antonio Development Services Department (DSD) requires these details for a proper fire and ventilation review. Incomplete plans are the #1 cause of rejection, adding 2–3 weeks for resubmission and delaying your construction schedule.
2. Miscalculating CFM (Cubic Feet per Minute) Requirements
Using manufacturer's default CFM or guessing based on hood size, rather than calculating the required exhaust volume per the International Mechanical Code (IMC) and local amendments. Under-sizing risks failing the final inspection and not capturing grease and heat. Over-sizing can violate make-up air requirements and lead to system rework, incurring additional engineering and permit revision fees.
3. Listing an Unlicensed Contractor or Missing Contractor Information
Failing to provide the full license number and business name for the mechanical contractor performing the hood installation, as required by Texas state law and the City of San Antonio. Applications with 'TBD' or incomplete contractor details are placed on hold. This mistake adds 1–2 weeks to processing while you obtain and submit the correct licensing documentation from your hired professional.

Prepare Construction Drawings & System Specs
Hire a licensed professional (architect or engineer) to create detailed construction drawings and specifications for the proposed hood and exhaust system. These must include a floor plan with equipment layout, exhaust duct routing, fire suppression system integration, and all equipment make/model numbers. Missing or insufficient drawings are the #1 cause of immediate application rejection by the Development Services Department (DSD). This step cannot begin until you have finalized your kitchen equipment layout.
Submit Application Packet via SAView Portal
File your complete application through the City of San Antonio's SAView online portal. You must upload the professional drawings, the completed permit application form (ApronPrep auto-fills key fields), and a copy of the contractor's state license. The DSD accepts no paper submissions for this permit type. You will need to create a SAView account and have your contractor's information and project address ready. Applications submitted after 3 PM typically enter the queue the next business day.
Plan Review by DSD & Fire Department
Your submitted drawings undergo a multi-departmental review. The DSD Building Inspections team checks for compliance with the International Mechanical Code (IMC) and local amendments, while the San Antonio Fire Department reviews the fire suppression system (ansul) integration and clearance. This is the longest phase. Expect at least one round of corrections ('revisions'); complex kitchens often require 2-3 revision cycles. Review status is updated in SAView.

See All RequirementsProcessing timelines vary significantly based on project complexity, the completeness of your application, and the current review volume at the Development Services Department (DSD). For standard kitchen hood installations reviewed under a Building Permit, plan review can take several weeks. Contact DSD directly for the most current estimate, as they do not publish a standard processing time for this specific permit type.
According to the official City of San Antonio fee schedule, the government filing fee for this permit is $0. However, this system is typically included as part of a larger mechanical or Building Permit, which has its own fee structure based on valuation. You may incur fees for plan review and inspections through that primary permit process, so verify total costs with the Development Services Department.
No. Permits for hood and exhaust systems are issued for a specific location and installation. If you move your restaurant or equipment, you must apply for a new permit at the new address. The new application will require a full review to ensure the system design complies with the International Mechanical Code and the specific conditions of the new space, as enforced by the San Antonio Development Services Department.
The installation permit itself does not require renewal. However, the system must be maintained in compliance with the San Antonio Fire Code. This involves annual inspections and certification by a licensed fire protection contractor to verify hood cleaning and proper operation. Failure to maintain certification can result in violations, similar to lapses in other required certifications like a Backflow Prevention Device Certification.
A city inspector will verify the installation matches the approved plans and complies with the International Mechanical Code (IMC) and International Fire Code (IFC). They will check for proper hood sizing, duct material and clearances, fire suppression system tie-ins, fan capacity, and termination points. The inspection is typically a final step before you can obtain your Certificate of Occupancy. Schedule inspections through the Development Services Department.
