No, you cannot use the Ooni Koda indoors. They are designed as an outdoor only pizza oven. The best way to ensure a smoky smell does not fill your home is by using the unit outdoors. You can use it in an enclosed porch or patio, but if possible place it on a porch or patio that has been screened from your home. In general, using a pizza oven indoors is not recommended due to smoke and fire safety concerns.
