Hood/Exhaust Ventilation System Permit in Memphis, Tennessee (2026)
Your kitchen ventilation system cannot be legally installed or operated without this permit from the Memphis & Shelby County Construction Code Enforcement Office (CCEO), often called a kitchen hood permit. Without this approval, your contractor cannot proceed, your final building inspection will fail, and the Fire Marshal can issue a stop-work order. Key facts:
- 20 fields in the application — ApronPrep auto-fills 17
- $0–$0 government filing fees for the permit itself, but associated plan review or inspection fees may apply
- Varies processing timeline based on plan review complexity and contractor scheduling

Why You Need a Hood/Exhaust Ventilation System Permit
You need a Hood/Exhaust Ventilation System Permit because installing or altering commercial kitchen ventilation triggers legal obligations under multiple enforceable codes in Memphis. The primary authority is the locally adopted International Mechanical Code (IMC), which is administered by the Memphis & Shelby County Division of Construction Code Enforcement under the City of Memphis Code of Ordinances, Chapter 6, Buildings and Building Regulations. This permit specifically addresses sections of the IMC that govern the capture, containment, and expulsion of grease-laden vapors and combustion products. Compliance with these mechanical codes is also intertwined with the state's accessibility requirements (Tennessee Accessibility Act) and fire safety provisions, as the system's installation affects egress paths and fire separation.
Operating a hood system without this permit, or failing an inspection, carries immediate and costly consequences. Based on Memphis's enforcement protocols, violations typically result in:
- Stop-work orders halting all construction, including unrelated trades, until the violation is corrected.
- Certificate of Occupancy denial, preventing you from legally opening your restaurant to the public.
- Required demolition of non-compliant work at your expense to allow for a proper inspection.
- Daily accruing fines as stipulated by local ordinance for unpermitted work.
- Voided equipment warranties and potential denial of insurance claims if a fire originates from an unpermitted installation.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of the 2026 code cycle, Memphis began enforcing the 2021 International Mechanical Code with local amendments, which includes updated requirements for grease duct clearance and fire damper ratings that directly impact hood system plans.

17 of 20 auto-filledBusiness Legal Name
textEnter the exact legal business name as registered with the Tennessee Secretary of State or local jurisdiction, matching your business license and legal documents.
COMMON MISTAKE: Using a DBA or trade name instead of the registered legal entity name (e.g., "Joe's Diner" instead of "Memphis Eats, LLC") will cause rejection.
Primary Contact Information
textProvide the full name, title, phone number, and email address of the person responsible for the permit application and available for inspector questions.
COMMON MISTAKE: Leaving out a direct phone number or providing an incorrect/out-of-service contact delays communication and can stall approval.
Project Address
textEnter the complete physical street address of the restaurant where the ventilation system will be installed, including suite or unit number.
COMMON MISTAKE: Providing a P.O. Box or mailing address instead of the physical location results in an automatic return of the application.
Building Type/Use
textSpecify the building's occupancy classification (e.g., A-2 Assembly, B Business, M Mercantile) and specific use (e.g., restaurant, fast food, commercial kitchen).
COMMON MISTAKE: Using vague terms like "food service" instead of the specific International Building Code occupancy group triggers a request for clarification, adding 1-2 weeks to review.
Project Description
textDescribe the scope of work in detail, including installation of a new hood/exhaust system, replacement of existing equipment, or modifications to ductwork.
COMMON MISTAKE: A description that is too brief (e.g., "install hood") fails to demonstrate code compliance intent, requiring a resubmission with more detail.
Cooking Equipment Details
textList all cooking appliances under the hood (e.g., 48" charbroiler, 36" flat top griddle, two 40-gallon fryers) with BTU ratings if available, as this determines hood sizing.
COMMON MISTAKE: Omitting even one piece of equipment (like a pasta cooker or steamer) leads to an under-sized hood design that will fail the plan review.
Tennessee Registered Architect/Engineer Engaged
checkboxCheck this box only if a Tennessee-licensed architect or professional engineer is responsible for preparing and stamping the construction drawings.
COMMON MISTAKE: Checking this box without actually having a licensed professional seals and stamps the drawings is a violation of state law and grounds for permit revocation.
architect_need_help
checkboxThis box is typically checked if you need a referral to a licensed professional; leaving it unchecked indicates you have secured the required design services.
COMMON MISTAKE: Mistaking this for a waiver of the professional requirement; checking it does not exempt you from submitting stamped plans if required by code.
Architect/Engineer Name and Registration Number
textIf an architect/engineer is engaged, provide their full name, company, and active Tennessee license/registration number exactly as it appears on their stamp.
COMMON MISTAKE: Providing an out-of-state license number or a number that does not match the stamp on the submitted drawings causes immediate rejection.
aware_of_requirements
checkboxThis is an applicant attestation that you understand mechanical drawings, cut sheets, and calculations are required for the permit review.
COMMON MISTAKE: Failure to check this box is interpreted as the applicant not being prepared to submit complete plans, resulting in the application being held as incomplete.

Top 5 Hood/Exhaust Ventilation System Permit Mistakes
1. Submitting Generic Manufacturer Drawings Without Memphis-Specific Details
Using the standard cut sheet from the hood manufacturer without adding Memphis-specific details like the exact duct routing through the building to the rooftop termination point. The Memphis & Shelby County Office of Construction Code Enforcement (OCCE) requires a site-specific mechanical drawing. Without it, your plan review is rejected for "incomplete plans," adding 2-4 weeks to your timeline while you hire a designer to draft compliant drawings.
2. Incorrectly Listing the NFPA 96 Cleaning Service Provider
Leaving the NFPA 96-compliant hood cleaning service section blank or listing a company not certified in Tennessee. Memphis code requires proof of a contract with a state-certified grease duct servicer before permit issuance. Applications are placed on hold until valid certification is provided, causing a 1-2 week delay. Verify your servicer's state certification number and list it on the application.
3. Miscalculating the Hood's CFM (Cubic Feet per Minute)
Entering an estimated CFM instead of the calculated value based on the hood's linear feet and type (e.g., Type I vs. Type II). An incorrect CFM triggers a review discrepancy with your HVAC contractor's separate make-up air permit application, freezing both permits. Recalculation and resubmission typically add 1-2 weeks. Provide the calculated CFM from your mechanical engineer or hood spec sheet.

See All RequirementsProcessing time varies per the Memphis & Shelby County Office of Construction Code Enforcement. It depends on project complexity and plan review workload—simple applications may take a few weeks, while complex designs require more detailed reviews. Contact the office directly for current timelines and confirm if a related Building Permit or Certificate of Occupancy is also required, as this can extend your schedule.
The government filing fee for this permit is typically $0–$0 for the basic application, as posted on the city fee schedule. However, plan review or inspection fees may apply separately, and you must verify the total cost with the Code Enforcement office. Not legal advice—confirm all fees with Memphis & Shelby County Office of Construction Code Enforcement.
No, these permits are location and equipment-specific. You must apply for a new permit at the new site, including new plan reviews and inspections. This is because system design must comply with the specific building codes and layout of the new space, similar to the process for a Backflow Prevention Device Certification.
This permit typically does not require annual renewal; it is a one-time approval for the installed system. However, you may need a re-inspection or new permit if you modify the hood system or change your cooking equipment. Always check with Memphis Code Enforcement before any alterations to ensure continued compliance.
A city inspector verifies the installation matches the approved plans, checking for proper hood dimensions, ductwork, fire suppression clearance, and exhaust rates. They also confirm the system vents to an approved exterior location and that all required UL labels are visible. Passing this inspection is often a prerequisite for obtaining your final Certificate of Occupancy.
