Dublin code enforcement trucks do drive around also. I had one come by years ago and harrass me for having a boat in my driveway for more than 3 days. (Stupid law, we have to hide our boats/RV vehicles.)
No in front yards, only back yards. I also run my own electrical company, and have trucks with my company name on them, and not allowed to park in driveway either. Commercial vehicles not allowed in driveways overnight. Is dumb.
I always found that rule so fucking stupid. Can't fence off your yard or have any sort of privacy around your own fucking house, what's the point of owning the fucking yard in the first place?
