Certificate of Occupancy in Seattle, Washington (2026)
Without a Certificate of Occupancy from Seattle's Department of Construction and Inspections (SDCI), you cannot legally operate your restaurant — lenders will not fund, landlords cannot lease, and health inspectors will shut you down. A Certificate of Occupancy (also called a CO or occupancy permit) confirms that your space meets all building, fire, and life-safety codes for food service use. Seattle's SDCI requires 35 fields on the application, and ApronPrep auto-fills 29 of them from your business profile. Government filing fees are typically included with your building permit package — contact SDCI to confirm current costs. Most applicants complete this form in under 15 minutes with ApronPrep's auto-fill.

Why You Need a Certificate of Occupancy
In Seattle, a Certificate of Occupancy (CO) is the legal document issued by the Seattle Department of Construction and Inspections (SDCI) that confirms your building or space complies with the approved construction plans and all applicable codes for its intended use as a food establishment. Its authorization is rooted in the Seattle Building Code (SBC), Seattle Fire Code (SFC), and the Washington State Accessibility Code (WSAC). These local ordinances, which are based on state and international model codes, collectively govern life safety, structural integrity, fire protection, and accessibility. You cannot legally occupy a new building, a newly constructed space, or a space that has undergone a change in its primary use (like converting a retail shop to a restaurant) without this final sign-off from the city.
Operating without a valid CO is a serious code violation with immediate and costly consequences. The issuing authority, SDCI, can enforce compliance through several escalating penalties:
- Stop-Work and/or Vacate Orders: The most immediate action. SDCI or the Seattle Fire Department can issue a notice requiring all work to cease or for the premises to be vacated immediately until violations are corrected.
- Denial of the CO: This halts your opening indefinitely. You cannot operate, your lease terms for opening may be breached, and your lender may withhold final funding.
- Fines and Daily Penalties: While specific fine amounts vary by violation severity and duration, code enforcement can levy substantial monetary penalties that accrue daily until compliance is achieved.
- Required Demolition: For work constructed without permits or that severely violates code, the city can order the non-compliant construction to be demolished at your expense.
- Insurance and Lease Voidance: Operating without a CO typically violates commercial property insurance policies and lease agreements. An incident in an unapproved space could lead to denied claims or lease termination.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: In 2025, SDCI formally integrated additional verification steps for commercial kitchen ventilation systems (Type I hoods) into the final CO inspection checklist, requiring specific performance test documentation from a licensed mechanical contractor prior to approval.

29 of 35 auto-filledBusiness Legal Name
textEnter the exact legal name of the entity that will own and operate the restaurant, exactly as it is registered with the Washington Secretary of State, your LLC filing, or your corporate charter.
COMMON MISTAKE: Using a 'doing business as' (DBA) name instead of the registered legal name, or using punctuation like 'LLC' when the official filing uses 'L.L.C.'
Restaurant Facility Address
textEnter the complete, physical street address of the restaurant premises, including suite or unit number if applicable, as it appears on your lease and utility accounts.
COMMON MISTAKE: Entering a mailing address, P.O. Box, or the address of a corporate headquarters instead of the specific location where food will be prepared and served.
Primary Owner/Contact Name
textEnter the full legal name of the individual who has the authority to sign for the business entity listed above and will be the main point of contact for the Seattle Department of Construction and Inspections (SDCI).
COMMON MISTAKE: Entering a business name again, or listing a project manager or architect instead of the legal owner or an authorized officer of the owning entity.
Owner Phone Number
textEnter a direct, working phone number for the owner/contact listed above, in a standard format (e.g., 206-555-1234).
COMMON MISTAKE: Providing a disconnected number, a front-desk/receptionist number, or a number for someone who cannot answer detailed questions about the construction project or business.
Owner Email Address
textEnter a valid, monitored email address for the owner/contact, which SDCI will use for all official correspondence and inspection scheduling.
COMMON MISTAKE: Using a generic or shared email (e.g., info@restaurant.com) that may not be checked daily, leading to missed deadlines or inspection notices.
Restaurant Type/Occupancy Classification
textEnter the specific use classification as defined by the Seattle Building Code, such as 'A-2 Assembly' for a restaurant with seating for 50 or more, or 'B Business' for a smaller cafe or take-out establishment.
COMMON MISTAKE: Using generic terms like 'restaurant' or 'food service' instead of the formal code classification, which determines specific life-safety and accessibility requirements.
Construction Permit Types Obtained
textList all relevant Seattle construction permits obtained for this project, such as 'Building Permit,' 'Mechanical Permit,' 'Electrical Permit,' and 'Plumbing Permit.'
COMMON MISTAKE: Omitting permit types that were required for the scope of work (e.g., forgetting 'Mechanical Permit' for HVAC work), which signals the project is not fully permitted.
Construction Permit Numbers

textProvide a concise description of all work completed under the listed permits, such as 'Interior build-out for new restaurant, including kitchen installation, dining area partition walls, and new restrooms.'
COMMON MISTAKE: Providing a vague description (e.g., 'remodel') that doesn't match the detailed scope reviewed and approved in the building permit plans, triggering a request for clarification.
All Construction Work Complete
checkboxCheck this box only when all permitted construction work is 100% finished, all required inspections have passed, and no active permits remain open for the project.
COMMON MISTAKE: Checking the box prematurely while minor punch-list items, final inspections, or sign-offs from other departments (like Fire) are still pending, which is grounds for immediate rejection.

Top 5 Certificate of Occupancy Mistakes
1. Applying Before Final Building Inspection
Submitting the Certificate of Occupancy application before the City of Seattle's Department of Construction & Inspections (SDCI) has completed its final building inspection. This is the most common reason for immediate rejection, as a 'pass' final inspection is a statutory prerequisite. This mistake adds 2-4 weeks to your timeline, as you must wait for the inspection and then re-queue your application. Avoid it by confirming with your general contractor that all permits are closed and the final inspection report is 'approved' in the Seattle Services Portal before you apply.
2. Incomplete Business License Verification
Failing to provide proof of an active Seattle Business License Tax Certificate, or listing a license that is 'pending' or for a different address. Seattle Municipal Code § 5.55.020 requires a valid license for the specific premises. Applications with mismatched addresses or inactive licenses are placed on hold, adding 1-2 weeks for correction. Avoid it by printing your current Seattle Business License Tax Certificate from the City's tax portal and ensuring the business name and address match your application exactly.
3. Incorrect Use Classification (IBC/Seattle Code)
Selecting the wrong 'Use and Occupancy Classification' from the International Building Code (IBC), such as 'A-2 Restaurant' instead of 'A-3 Assembly' for a fast-casual model with limited seating. This misalignment with your approved building and fire plans triggers a costly and time-consuming plan review by SDCI and the Seattle Fire Department. This error can add 4-8 weeks of re-review. Avoid it by matching the classification exactly to what is listed on your approved construction documents, not your marketing description.

Timeline: Varies
Step 1: Complete all construction and build-out work according to approved permits and Seattle building code
Finish all interior construction, kitchen installation, flooring, walls, and finishes in compliance with your approved construction permits and Seattle Municipal Code Title 22. This is the longest phase — most restaurant build-outs take 4–12 months depending on scope. Do not schedule inspections until your general contractor confirms all work is complete.
Step 2: Ensure all required inspections are passed (framing, mechanical, electrical, plumbing, final)
Schedule and pass all five required inspections with the Seattle Department of Construction & Inspections (SDCI): framing, mechanical, electrical, plumbing, and final. Each inspection typically takes 1–2 hours on-site. SDCI requires 24 hours' notice before each inspection — book them sequentially as phases complete to avoid rework delays.
Step 3: Verify compliance with State Building Code, Seattle Municipal Code, and State Accessibility Code (ADA)
Review the final inspection report to confirm all work meets Washington State Building Code, Seattle Municipal Code §22.101–22.900, and the Washington State Accessibility Code (which mirrors the ADA). SDCI inspectors flag non-compliance on the inspection report — address every item before requesting final approval. Non-compliant items add 1–3 weeks for rework and re-inspection.

See All RequirementsProcessing timelines for a Certificate of Occupancy in Seattle vary depending on whether your building requires initial construction inspection or is a conversion of an existing space. Per the Seattle Department of Construction & Inspections (SDCI) website, initial inspections typically occur within 2–4 weeks of application submission, but the final approval timeline depends on whether corrections are needed — most restaurants receive approval within 4–8 weeks if no violations are identified. Contact SDCI directly at (206) 684-8600 or visit the SDCI inspection scheduling portal to confirm current processing times for your specific project type.
The government filing fee for a Certificate of Occupancy in Seattle is $0–$0, as there is no separate filing fee charged by SDCI for this document. However, you will incur costs for required inspections (building, fire, and health inspections), which are typically bundled into your Building Permit fees — contact SDCI at (206) 684-8600 to request a detailed fee estimate for your specific project. Additionally, if you need to complete work or repairs identified during inspection before occupancy is approved, those construction costs are separate from permit and inspection fees. Not legal advice — verify current fees with SDCI.
No — a Certificate of Occupancy is location-specific and tied to the physical address and building configuration where it was issued. If you open a restaurant at a new location, you must apply for a new Certificate of Occupancy for that address, which will require a new Building Permit and inspections by SDCI, Seattle Fire Department, and Public Health. Contact SDCI to begin the process for your new location.
A Certificate of Occupancy does not require renewal — it remains valid for the life of the building and your use of it, provided you do not make major structural changes or significantly alter your restaurant's layout or occupancy classification. However, if you expand your seating capacity, modify your kitchen, or change your restaurant's use classification (e.g., from quick-service to full-service with a bar), you must notify SDCI and may need to obtain a new or amended Building Permit and Certificate of Occupancy. Contact SDCI at (206) 684-8600 to determine if your planned changes require a new certificate.
SDCI, Seattle Fire Department, and Public Health conduct separate inspections to verify that your restaurant meets building codes, fire safety codes, and health and sanitation requirements. Inspectors check structural integrity, emergency exits, fire suppression systems, kitchen ventilation, plumbing, electrical systems, and food service equipment — per the Seattle Fire Code and Washington State Food Code, violations must be corrected before occupancy is approved. If violations are found, you receive a written list and have a specified timeframe (typically 10–30 days) to correct them and request a re-inspection; once all corrections are verified, SDCI issues your Certificate of Occupancy.
