Presidio Terrace is a gated, privately owned street with a distinctive circular shape in the neighborhood of the same name, home to some of San Francisco’s most expensive and exclusive abodes. 
  
 But little did its tony residents realize the city sold the entire thing out from under them two years ago. 
  
 That’s the story as the San Francisco Chronicle tells it: Turns out the Presidio Terrace Association neglected to pay taxes on its private pavement for some 30 years. So City Hall put the street—that is, the actual street and sidewalks—up for auction in 2015. 
  
 The winning bid from an investor/engineer South Bay couple came to just over $90,000—barely enough to buy the front door of any of the multimillion-dollar homes in the neighborhood, but also almost a hundred times the sum of the delinquent taxes. 
  
 It seems that Presidio Terrace neighbors weren’t aware of the auction, the sale, or the tax bill until earlier this year. And the street fee that they failed to pay for all of those years? Less than $14 annually. 
  
 Amazingly, all of this really did happen, at least according to the lawsuit that the Presidio Terrace Association filed against their new landlords, Tina Lam and Michael Cheng, in July. 
  
 In the complaint, homeowners note that the association has owned and maintained the O-shaped avenue since 1905. So why’d they drop the ball paying the tax man? According to the suit: 
  
 “The Association has not paid those taxes because the City has been sending the property tax bills to the Association at the following address: 47 Kearny Street. [...] Which is not the address of the association or any member. “After research, the Association is informed and believes that this address was associated with an accountant who last performed work for the Association in the 1980s. [...No] member of the Association was aware that property taxes has not been paid.” 
  
 The Kearny Street address belongs to the property management company Hanford Freund. Nobody at HF was immediately available for comment. 
  
 Update: HF’s Senior Vice President Timothy Falvey told Curbed SF that his company never dealt with the Presidio Terrace Association, in spite of the cited address. 
  
 “Handford Freund has never managed the Presidio Homeowners Association or whatever it may be named. I’ve been there for almost 30 years and never heard any reference to it or seen anything in our files about it, and I’m confident that my firm has never managed it. [...] We have nothing to do with it.” 
  
 The suit further claims that the city “made no reasonable effort to inform the Association or any of its members that the Common Area was subject to sale” and that no one on the street found out about it until May 30 of this year. 
  
 Neighbors hope the court will rescind the 2015 sale and return ownership to them. Meanwhile, a spokesperson for the city’s Treasurer-Tax Collector told the Chronicle’s Matier and Ross that the office did everything required under the law and that everyone else in the city manages to keep their property taxes straight. 
  
 The neighbors have also petitioned the Board of Supervisors to reverse the sale, with a hearing set for October. 
  
 In the meantime, the street’s new owners are considering instituting a parking fee in the neighborhood. But if neighborhood residents aren’t keen on paying a parking fee, that’s no problem for the street’s new owners. 
  
 Matier and Ross note: “[I]f the Presidio Terrace residents aren't interested in paying for parking privileges, perhaps some of their neighbors outside the gates—in a city where parking is at a premium—would be." ||||| Thanks to a little-noticed auction sale, a South Bay couple are the proud owners of one of the most exclusive streets in San Francisco — and they’re looking for ways to make their purchase pay. 
  
 Tina Lam and Michael Cheng snatched up Presidio Terrace — the block-long, private oval street lined by 35 megamillion-dollar mansions — for $90,000 and change in a city-run auction stemming from an unpaid tax bill. They outlasted several other bidders. 
  
 Now they’re looking to cash in — maybe by charging the residents of those mansions to park on their own private street. 
  
 Those residents value their privacy — and their exclusivity. Past homeowners have included Sen. Dianne Feinstein and her financier husband, Richard Blum; House Democratic leader Nancy Pelosi; and the late Mayor Joseph Alioto. A guard is stationed round the clock at the stone-gate entrance to the street to keep the curious away. 
  
 So imagine the residents’ surprise when San Jose residents Cheng and Lam wound up with the street, its sidewalks and every other bit of “common ground” in the private development that has been managed by the homeowners since at least 1905. That includes a string of well-coiffed garden islands, palm trees and other greenery that enhance the gated and guarded community at the end of Washington Street, just off Arguello Boulevard and down the hill from the Presidio. 
  
 “We just got lucky,”said Cheng, a real estate investor. 
  
 The homeowners, however, are crying foul and want the Board of Supervisors to negate the sale. 
  
 The couple’s purchase appears to be the culmination of a comedy of errors involving a $14-a-year property tax bill that the homeowners association failed to pay for three decades. It’s something that the owners of all 181 private streets in San Francisco are obliged to do. 
  
 In a letter to the city last month, Scott Emblidge, the attorney for the Presidio Homeowners Association, said the group had failed to pay up because its tax bill was being mailed to the Kearny Street address used by an accountant who hadn’t worked for the homeowners since the 1980s. 
  
 Two years ago, the city’s tax office put the property up for sale in an online auction, seeking to recover $994 in unpaid back taxes, penalties and interest. Cheng and Lam, trawling for real estate opportunities in the city, pounced on the offer — snatching up the parcel with a $90,100 bid, sight unseen. 
  
 Since the purchase in April 2015, the couple have been quietly sitting on the property, talking to a number of land-use attorneys to explore their options. 
  
 “We were looking to get title insurance so it could be marketable,” Cheng said. 
  
 He and his wife see plenty of financial opportunity — especially from the 120 parking spaces on the street that they now control. 
  
 “We could charge a reasonable rent on it,” Cheng said. 
  
 And if the Presidio Terrace residents aren’t interested in paying for parking privileges, perhaps some of their neighbors outside the gates — in a city where parking is at a premium — would be. 
  
 Unsurprisingly, the residents were more than a little upset when they belatedly found out what had happened. 
  
 They didn’t learn that their street and sidewalks had been sold until they were contacted May 30 by a title search company working on behalf of Cheng and Lam, said Emblidge. The title search outfit wanted to know if the residents had any interest in buying back the property from the couple, the lawyer said. 
  
 “I was shocked to learn this could happen, and am deeply troubled that anyone would choose to take advantage of the situation and buy our street and sidewalks,” said one homeowner, who asked not to be named because of pending litigation. 
  
 Last month, the homeowners petitioned the Board of Supervisors for a hearing to rescind the tax sale. The board has scheduled a hearing for October. 
  
 In addition, the homeowners association has sued the couple and the city, seeking to block Cheng and Lam from selling the street to anyone while the city appeal is pending — a move residents fear could complicate their efforts to reclaim the land. 
  
 The residents say the city had an obligation to post a notice in Presidio Terrace notifying neighbors of the pending auction back in 2015 — something that “would have been simple and inexpensive for the city to accomplish.” 
  
 Treasurer-Tax Collector Jose Cisneros’ office says the city did what the law requires. 
  
 “Ninety-nine percent of property owners in San Francisco know what they need to do, and they pay their taxes on time — and they keep their mailing address up to date,” said spokeswoman Amanda Fried. 
  
 “There is nothing that our office can do” about the sale now, she added. 
  
 Fried said that as far as she knows, the Board of Supervisors “has never done a hearing of rescission” — and that because it’s been more than two years since Cheng and Lam bought the property, it could be tough to overturn the sale now. 
  
 As for the threat to charge them for parking, the residents suspect it’s part of a pressure campaign by the couple to force the homeowners association to shell out big bucks to buy back the street. 
  
 The couple, however, say they’re in no hurry to sell. 
  
 “I’m a first-generation immigrant, and the first time I came to San Francisco I fell in love with the city,” said Lam, an engineer in Silicon Valley who was born in Hong Kong and came to the U.S. for college. 
  
 “I really just wanted to own something in San Francisco because of my affinity for the city,” Lam said. 
  
 There’s a bit of irony in the couple’s purchase. Until a 1948 U.S. Supreme Court ruling banning the enforcement of racial covenants, homes in Presidio Terrace could be purchased only by whites. 
  
 “The more we dug into this,” said the Taiwan-born Cheng, “the more interesting it got.”

Output:
A real estate-savvy couple is now the proud owner of the streets and sidewalks of uber-wealthy, uber-exclusive San Francisco gated community Presidio Terrace. But residents of the 35 mega-mansions lining the private, oval-shaped street are pushing back, reports the San Francisco Chronicle. South Bay couple Tina Lam and Michael Cheng scooped up the street at a city-run auction for a little over $90,000 in 2015. The street was up for grabs due to unpaid property taxes that the community’s homeowner’s association neglected to pay for 30 years. Seeking to recover the $14 owed per year, the city put the street up for sale. (Plus interest and penalties, the bill amounted to a whopping $994.) Residents say they didn’t know about the back taxes or sale until this May, when a title search company hired by Cheng and Lam sent out letters asking if property owners were interested in buying the street back. Per Curbed, the Presidio Terrace Association filed a complaint claiming that the address the city used to bill the association was not associated with any of its members. A Treasurer-Tax Collector spokesperson says the city followed all requirements, adding that almost all local homeowners "pay their taxes on time—and they keep their mailing address up to date.” According to the Chronicle, Cheng and Lam’s property comes with plenty of financial opportunity, including making residents pay for street parking. But Lam asserts that owning the once white-only property goes beyond dollar signs: “I really just wanted to own something in San Francisco because of my affinity for the city.” Meanwhile, the association has petitioned the Board of Supervisors to negate the sale—a hearing is scheduled for October—and sued the couple and the city in an attempt to block the property being sold to anyone else while the appeal is pending.
