In a city where housing politics can make your head spin, the Board of Supervisors just made a surprisingly straightforward call: rejecting an illegal conversion that turned four rental units into a single mansion.

Let that sink in. Someone took four housing units off the market — in the most housing-starved city in America — and merged them into one mega-unit. The Board said no. Good.

Now, regular readers know we're not usually in the business of cheering on the Board of Supervisors. This is the same body that has spent decades making it nearly impossible to build new housing while hand-wringing about affordability. But even a broken clock is right twice a day, and this is one of those times.

Here's the thing: property rights matter enormously. We believe that deeply. But property rights operate within a legal framework, and you don't get to illegally gut four apartments to build yourself a palace, then ask the city to bless it after the fact. That's not liberty — that's entitlement. As one local resident put it bluntly: "When I think about 'entitlement culture' and 'government handouts,' the very first thing that comes to mind is a San Francisco property owner."

Harsh? Maybe. But not wrong.

San Francisco has roughly 46 housing units per 100 residents who want them. Every unit matters. When someone removes three net units from the rental market for personal gain, that's not a victimless act — it tightens supply and pushes rents higher for everyone else. The free market works best when people play by the rules, and retroactively legalizing illegal conversions sets a terrible precedent.

The real question is why this kind of thing happens in the first place. The answer, predictably, is that San Francisco's permitting and enforcement apparatus is so slow and so dysfunctional that people routinely do whatever they want and ask forgiveness later. The city needs to crack down faster — before the drywall goes up, not years after.

We'll keep pushing for more housing, fewer regulations on building new units, and a streamlined permitting process. But defending illegal conversions that shrink the housing stock? That's not the hill to die on.
