Every San Franciscan has one. That store you walk past three times a week, never see a single customer inside, and think: there is absolutely no way the math works here.

For many, the reigning champion is Phil's Electric Co. in the Marina — a vacuum repair shop sitting on some of the most expensive retail real estate in the Western Hemisphere. The foot traffic appears to hover somewhere between "none" and "the owner's cousin stopped by." And yet, Phil's endures. Year after year. Rent cycle after rent cycle.

The beautiful thing? When San Franciscans start comparing notes on their favorite mystery businesses, something fascinating happens: people come out of the woodwork defending these places. Turns out Phil's has a quietly devoted customer base. Turns out that random little repair shop is actually a neighborhood institution.

And here's where it gets interesting from a policy standpoint. These micro-businesses — the vacuum fixers, the key cutters, the inexplicable lamp stores — are exactly the kind of enterprises that San Francisco's regulatory environment makes nearly impossible to start today. Between permit fees, compliance costs, and the bureaucratic gauntlet of opening any storefront in this city, a new Phil's Electric could never happen in 2025.

We spend a lot of time in San Francisco talking about supporting small businesses. City Hall loves the ribbon-cutting photo ops. But the actual cost of doing business here — commercial rents amplified by restricted supply, layers of licensing requirements, and tax structures that punish the little guy — tells a very different story.

The stores that make you ask "how does this stay open?" are actually monuments to a simpler era of commerce, when someone could just... open a shop and fix things. The fact that they survive is less a mystery and more a minor miracle of stubbornness triumphing over a city that increasingly makes small-scale entrepreneurship a luxury.

Long live Phil's. And maybe let's make it possible for the next Phil to actually get started.
