No? You're looking at an extremely local level at SF, which is obviously influenced by the tech industry which is hosting some of the world's largest companies like Apple, who's revenue tenfolded since 2007.
If you look at median home sales prices in the US in general however, you get this picture (just compare the peak of 2007 till today):

I'm not seeing an 88% increase. Now if you correct that picture for median household income in the US, for the same period:

You'll see, income-adjusted home prices haven't shot up that much since the last peak.
Then you have to contextualise further, and look at interest rates. After all, you're not buying homes in cash. For almost all of us, when we 'buy' a home, we're really just signing a rental contract for cash (a loan), and our housing costs consists of servicing this loan, the mortgage payments. The principal sum matters of course, which went up as prices grew, but so does the interest rate, which is at a historic low and responsible for the prices growing. You can't just ignore interest rates.
So if you actually look at monthly payments, which is by definition corrected for interest rates, and correct that for income increases, really what we talk about when we say 'housing costs', really isn't anywhere near the record levels usually talked about in the media, discussion forums etc.
And THEN you correct that for the larger homes etc.
Now I tried to give a longer historical perspective of price increases for a few generations beyond mine, but if you want to nitpick that and make a joke about jacuzzis, fine by me.
My point is that if we break down what a 'change in housing costs' really should mean, we typically want to talk about:
income-adjusted, monthly (periodical) cost for a square foot.
What we tend to do is: ignore the fact our incomes rose greatly in nominal terms, yet express increases housing in nominal terms, ignore interest payments dropping for decades reducing the costs to finance these homes, and then ignore the fact these homes have doubled in size in the post-war era and typically have much better amenities.
And that's not a fair representation, I think.
