Back in April, we found out that you could buy a San Francisco driveway for $35,000. Perhaps it was only a matter of time before we found out what the going rate was for an actual San Francisco street. Turns out, it’ll run you around $90,000.

That’s how much Tina Lam and Michael Cheng paid after winning an auction to become the proud owners of Presidio Terrace, an oval-shaped path lined with 35 multimillion-dollar mansions in Presidio Heights. The street became available when the city reclaimed it over an unpaid tax bill by the homeowner’s association, per the San Francisco Chronicle.

So now, the couple owns not only the street but also the sidewalks and all of the “common ground” within the exclusive enclave, including garden islands and palm trees within the gated community. You can probably guess where this is going… 

The new owners of the street are considering charging the residents of this super-rich neighborhood to park on the street right outside their own houses. And if the residents balk at that offer, the owners would consider renting out 120 parking spaces in front of these luxury homes to the public. Meanwhile, the Presidio Terrace homeowners are demanding that the Board of Supervisors negate the sale and return ownership of the street to them.

How did things get this far? Turns out you can blame some faulty paperwork. Because Presidio Terrace is a private street, every homeowner is required to pay a $14-a-year property tax bill to San Francisco. According to a lawyer for the homeowners, per the Chronicle, no one had paid taxes in over three decades because the bill was being sent to an address no longer in use. Two years ago, the city quietly put the property up for auction to raise the lost revenue and the couple bought it legally in April 2015, beating out multiple bidders. It wasn’t until May 2017 that homeowners found out about the sale when a title company contacted them asking if the association was interested in buying back the street.

The homeowners association is currently awaiting an October hearing with the Board of Supervisors where they’ll plead their case to rescind the sale and return ownership of the street to them. They are also suing Cheng and Lam to block them from selling the street to a third party while their appeal is pending. 

A city spokeswoman told the Chronicle that the Board of Supervisors “has never done a hearing of rescission” and that given so much time has passed it might be difficult to do so.

The lesson is, as always, make sure you’re paying your taxes. Otherwise, someone might start charging you to play hopscotch on your own sidewalk.
