SAN FRANCISCO (CBS SF) — San Francisco may be raking in profits from parking meters when parking is supposed to be free.

Signage on many San Francisco parking meters still indicates Sunday enforcement, even though the city recently stopped charging for Sunday parking.

“I don’t know why they’re not saying free parking, because that’s what it is now,” one man told KPIX 5.

Paul Rose of the San Francisco MTA says the city wants to clear up the confusion, but it’s not as simple as slapping on a new sticker.

“If we were to cross out something, or professionally cover it with a sticker, not everyone would believe that,” Rose said.

Instead, the city has chosen to upgrade all the meters to smart meters that won’t accept payments on Sunday. But, the changeover won’t be complete until February.
