Why You Need a Hood/Exhaust Ventilation System Permit
In Spokane, installing a commercial kitchen ventilation system without this permit violates the Washington State Building Code (WSBC), specifically the International Mechanical Code (IMC) Chapter 5 adopted under WAC 51-52-0500. The City of Spokane's Building Services Department administers this code locally. The permit process ensures your hood, ductwork, exhaust fan, and fire suppression components are sized correctly and installed to specifications reviewed by a plans examiner, confirming compliance with critical safety standards for fire prevention, air quality, and energy efficiency. This review is mandatory; skipping it means your restaurant is operating with an unapproved, and likely unsafe, mechanical system from the moment you turn on the equipment.
Proceeding without this permit—or failing inspection after unpermitted work—triggers immediate and costly enforcement actions by Spokane Building Services. Based on the city's enforcement procedures, common consequences include:
- Stop-Work Order: All construction activity halts immediately. You cannot open or continue kitchen build-out until the order is lifted, which requires paying penalties and submitting the proper permit application retroactively.
- Denial of Certificate of Occupancy (C of O): The city will not issue your final C of O, legally preventing you from opening your restaurant to the public.
- Required Demolition: Building officials can order the removal of all non-compliant, unpermitted work (e.g., tearing out newly installed ductwork and hoods) at your expense so it can be rebuilt correctly under permit.
- Daily Fines: While specific amounts vary by violation, the city can assess daily monetary penalties for each day the unpermitted system is in place or work continues under a stop-work order.
- Insurance and Lease Issues: Operating without required permits voids most commercial property insurance policies for related claims (e.g., fire). Landlords can also cite lease violations for unpermitted alterations, potentially leading to eviction.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, Spokane Building Services has fully integrated electronic plan review for mechanical permits, which can reduce initial review timelines for complete, well-prepared applications.

Top 5 Hood/Exhaust Ventilation System Permit Mistakes
1. Submitting Generic Manufacturer Diagrams
Applicants often attach the manufacturer's generic cut sheet instead of a site-specific, sealed mechanical drawing. The Spokane Building Department requires drawings that show the exact routing from the hood through the roof/wall, including all clearances to combustible materials. This mistake causes an immediate plan review rejection, adding 1–2 weeks to your timeline while you commission new drawings.
2. Understating Hood Size or BTU Rating
Entering an approximate hood dimension (e.g., '6-ft hood') or an incorrect appliance BTU total is a common error. The permit fee and system specifications are based on these precise values. An understated BTU rating can lead to an undersized exhaust system being approved, which will fail the final inspection. Verify all appliance nameplate BTU ratings and measure the hood's exact length, width, and depth.
3. Incorrectly Listing the Contractor
Using a restaurant's general contractor instead of the licensed mechanical contractor who will install the ductwork and fan causes permit holds. In Spokane, the hood ventilation system must be permitted under the Washington State-licensed mechanical contractor performing the work. List the wrong entity, and the application won't be processed until it's corrected, delaying your project start by several business days.

Gather Documentation & Create Plans
Prepare a detailed site plan, mechanical drawings, and equipment specifications for your hood and exhaust system. You'll need the manufacturer's cut sheets (specification pages) for your selected hood, fan, and any grease filters. Include the kitchen floor plan showing the hood's location relative to cooking appliances. Plans missing equipment specs are the top cause of plan review delays, adding 1-2 weeks.
Submit Application Packet to Spokane Building & Planning
File your completed application form, prepared plans, and payment for government filing fees with the Spokane Building & Planning Department. Submit online through the city's ePermit portal or in person at the Permit Services counter. Applications require the licensed mechanical contractor's information and their state license number. Incomplete applications are held for correction and restart the review clock.
Plan Review by Building & Fire Officials
Your plans undergo technical review by both Building and Fire Department staff to ensure compliance with the International Mechanical Code (IMC), International Fire Code (IFC), and Spokane Municipal Code. They will verify hood sizing, duct routing, fire suppression integration (if required), and exhaust termination points. Expect comments requesting clarification or corrections; prompt response is key to keeping the timeline under 4 weeks.

See All RequirementsProcessing timelines vary significantly based on project complexity and city review workload. A straightforward commercial kitchen exhaust system may be reviewed faster than a multi-hood custom design, which triggers more detailed plan review. Contact the Spokane Building Department to confirm current processing times for your specific project scope.
Government filing fees for this permit range from $0 to $0, as per the Spokane Building Department fee schedule. However, the total permit cost is typically based on the valuation of the mechanical work, which will be calculated during plan review. Other related permits, such as a Building Permit for structural changes, carry separate valuation-based fees.
No, these permits are specific to the installation address and equipment described on the application. Permits are non-transferable; if you move or install a new hood system, you must apply for a new permit. Similarly, equipment like your grease interceptor requires its own Backflow Prevention Device Certification which is also site-specific.
The installation permit itself does not require renewal. However, the operational systems it covers are subject to ongoing compliance and periodic inspections by the Fire Department or Building Safety. You must maintain the system according to code and may need to obtain new permits for any modifications or replacements.
A city inspector verifies the installed system matches the approved plans and complies with the International Mechanical Code and NFPA 96 standards. They check hood placement, ductwork, fire suppression system integration, clearance to combustibles, and make-up air provisions. Passing this inspection is required before you can obtain your final Certificate of Occupancy.
