"If someone in my area set up a kennel in their garage, you'd probably have the city coming down on the owner with fines due to not only being unlicensed but also because it would violate code. You can bet that neighbors would complain about the barking and report the owner to the authorities."

I don't see how this applies at all. I was thinking about maybe a 4 dog capacity. How is having 4 dogs in my large garage different than 4 dogs inside my house? Any barking issue inside my house would be the same inside my garage. I also don't live in super close proximity to my neighbors. I'll look this up later, but I don't see how it would violate any codes that it would not violate if the dogs were in the house. I am not proposing a typical large kennel situation.

Thinking about becoming a sitter but dogs not allowed in house. I have a huge yard which I will fence and a big garage where I can install separate kennels. Assuming the dogs will sleep in the heated garage and play under supervision in the yard (either individually or together, depending on how they get along), and I take them for at least one walk each per day, will people be interested in booking with me? Just wondering how important it is to potential clients that dogs be allowed in the home. Thanks for sharing your experiences!
