Something predictable is happening around San Francisco's latest real estate tax measure — and if you're not paying attention, you might miss it.

A narrative is forming. And like most narratives that take shape around San Francisco ballot measures, it's being built more on vibes and political convenience than on actual numbers.

Here's what we know: San Francisco has a long, proud tradition of layering taxes onto real estate transactions with the stated goal of fixing housing affordability — and an equally long tradition of those taxes failing to move the needle in any meaningful way. Transfer taxes. Vacancy taxes. Special assessments. The list grows. The housing crisis doesn't shrink.

So when a new real estate tax measure comes down the pike and supporters start framing opposition as heartless or pro-developer, pump the brakes. That's the spin. The real question — the one that deserves a straight answer — is whether this measure would actually produce the outcomes it promises, or whether it would generate a pile of revenue that quietly disappears into the city's famously bloated administrative apparatus.

San Francisco already ranks among the most expensive places in the world to develop and own property. Every new tax layer changes the calculus for builders, landlords, and buyers. Sometimes that's a feature. Often it's a bug. The difference matters enormously when you're talking about a city that desperately needs more housing supply.

We're not here to tell you how to vote. We're here to tell you to be skeptical — of the breathless endorsements, of the doom-and-gloom opposition, and especially of anyone who acts like the math is simple.

Ask where the money goes. Ask who controls it. Ask what happens if the projections are wrong — because in San Francisco, the projections are almost always wrong.

The false narrative is just getting started. Don't let it do your thinking for you.
