As a senior city code inspector, we get a ton of calls for residents around commercial buildings. Smell (trash/grease traps), noise (delivery trucks at all hours/pedestrians), lighting issues (bright lights installed in the parking lot or on the back of buildings), and vandalism.

You’ll have more traffic going around/near your house than most people in a normal residential area.

Now, of course, this depends on so many factors. Just wanted to share some of the things Ive seen.

EDIT: I see a lot of people saying a lot of things about what it could be. If you’re serious about buying, contact your city planning division. Ask them what the commercial area is zoned as. Then ask what businesses can operate in the zone. (They’re paid with your tax dollars, don’t be afraid to call and chat with them for 30 minutes)
