Hosting on Airbnb or VRBO? Don’t Let Your Septic System Delay Your Business License.
If you operate a Short-Term Rental (STR) in the Okanagan, you know the regulations are changing. Cities like Kelowna, West Kelowna, and the Regional District (RDCO) are constantly updating the rules for business licenses. Depending on your location and specific zoning bylaws, there is one requirement that catches many property owners off guard: The Septic Capacity Assessment.
Why might the City ask for this?
You might wonder: “My septic system works fine for my family, why is this an issue?”
The answer lies in Daily Design Flow (DDF). Most residential septic systems were designed for a specific residential occupancy (e.g., a family of 4). However, vacation rentals often have higher occupancy rates and erratic water usage (more showers, laundry, and dishwasher loads).
The licensing authority may require proof that your existing system can legally and physically handle the maximum number of guests you advertise. Without this “Capacity Assessment” or “Performance Review,” your business license application may face delays.
What is an STR Septic Assessment?
This is not just a standard tank pump-out receipt. It is a formal review conducted by an Authorized Person (ROWP Practitioner). At Affordable Septic, our process follows a strict protocol:
Step 1: Record Review (The Foundation) We analyze the original filing documents from Interior Health. This tells us the legal, intended capacity of your system.
Step 2: Verification (Onsite or Desk) We need to confirm that what is in the ground matches the paperwork.
-
Note: If your records are recent and complete, a “desk audit” might suffice. However, if records are old or unclear, an onsite inspection is required to visually verify components.
Step 3: Capacity Calculation We compare your system’s engineering limits against your proposed guest occupancy. This calculation determines if your system is compliant.
The Results: Two Possible Paths
Unlike a simple check-up, the outcome depends on the math:
-
Path A (Compliant): If your system handles the requested load, we issue the Official Capacity Assessment Letter. You submit this to the municipality to move your license forward.
-
Path B (Non-Compliant): If the system is undersized for your rental goals, we cannot simply “sign off.” Instead, we provide a Design Proposal to expand or upgrade the system to meet regulations so you can operate legally and safely.
What if I don’t have records?
This is a common issue with older properties. If Interior Health has no records, or if your system is undersized, being prepared is critical. We may need to perform a more in-depth investigation or file a new design to bring the system up to code.
Secure Your Season Now
Don’t wait until the busy booking season starts to sort out your paperwork. If the municipality requests an assessment, having a professional team ready to help can save your listing from unnecessary downtime.
