Yes, they are. Local news blogger Erin Holness at News Me Baby became frustrated enough with those PODS (Portable On Demand Storage) that she researched the legality of them on Los Angeles streets. "Those god-damned PODS," she bemoaned. "As if parking wasn't hard enough, some lazy neighbor has had one of those PODS delivered to the curb outside their building/house. The POD takes up at least 1.5 legitimate parking spots and it sits there FOREVER."
Because a POD is not a vehicle, it falls under the jurisdiction of the Street Services Investigation & Enforcement office and is a violation of obstructing the public right of way.
"When asked how companies like PODS get away with dumping these things on the corner, my Street Services source tells me 'they just hope no one will say anything,' found to Holness.
