It's hard to get both sides happy. The commerical side wants lots of cars and traffic for customers. The residents want peace and quiet. Then there is a very limited range of acceptable businesses. You'd have difficulty putting a dog daycare in due to noise. It's gotta be small, low traffic and quiet. There are only so many vets, daycare, clinics, coffee shops and corner stores an area can sensibly have. Then they charge too much and the commerical space stays empty for a year and looks terrible.
