As well you should. It is a service (and one that the city seems to be able to do effectively) that the city provides to discourage double parking. The signs must be posted 48 hours in advance. We had 3 cars towed the morning of our move, 3 cars who willingly parked there the night before, having signs and caution tape posted to alert them. Responsibility is a thing, and folks can learn the hard way sometimes.

We moved from our row home to a single family home. Best bet is getting a ROW permit. Here’s who you want to contact: Right of Way Permit Baltimore City Dept. of Transportation

Depending on the neighborhood you may have trouble either double parking or finding a spot close enough to the house. This allows you to reserve a space for the moving vehicle.
