The San Francisco apartment where Sam Altman and Greg Brockman launched tech giant OpenAI is for sale — and the asking price raises an interesting question about what famous addresses are actually worth.
The two-level Victorian apartment at 977A 21st St. in the Mission District is listed for $1,545,000. The renovated three-bedroom, two-bath unit offers 1,800 square feet, vaulted ceilings and white oak floors (1). By San Francisco standards, the price isn't outrageous — a similar 3/2 property a few streets away is listed at $1.6 million (2).

But the listing for Brockman's former rental leans hard into the story: Brockman was renting the space when he and Altman built the nonprofit that would eventually lead to ChatGPT. In fact, the living room, according to listing agent Shane Ray, served as OpenAI's original office.
Which raises the question — how much of that price tag is for the apartment and how much is for the story?
Famous addresses have a complicated track record
Brockman's former apartment isn't the only property to get attention for claiming famous tech founder residents. The Los Altos home where Steve Jobs grew up and the attached garage, which reportedly served as Apple's official early day headquarters, was designated as a historical site in 2013 (3). However, Apple co-founder Steve Wozniak later told the Guardian that the story about starting the company in the garage was "a bit of a myth."
"The garage didn't serve much purpose, except it was something for us to feel was our home," said Wozniak. "We had no money. You have to work out of your home when you have no money (4)."
The Facebook house is an even murkier case. A six-bedroom Los Altos rental where Mark Zuckerberg and early Facebook co-founders lived in the summer of 2004 was briefly listed for sale, then relisted in 2022 as an $11,000-a-month rental. Co-founder Dustin Moskovitz said there was nothing historic about the home, stating they launched Facebook from a Harvard dorm room (5).
With that track record, it seems unlikely that Brockman's previous rental property will increase in value solely due to the famous name attached. However, comparing prices to other similar properties around 977A 21st St. shows that the pricing is fairly in line with theirs (6).

How to think about properties with a 'story' when buying
The OpenAI apartment is an interesting piece of real estate and tech lore, but buyers should be careful when considering purchasing a home with a historical or cultural story attached. While there can be added value, it doesn't always work out.

Take, for example, what happened to the family that owned the property used as Walter White's home in "Breaking Bad." After being harassed for years, the family tried to list the home for $3.99 million, but it never sold. A year later, it returned to the market with an asking price of $400,000 — just over the estimated value (7). It was later sold for $1.3 million (8). The house from the movie "A Christmas Story" is now a museum that offers overnight stays for $200 to $600 (9) per night.
If you're considering investing in a property with historical significance, here are a few things to keep in mind:
- Don't pay for the story alone: Strip away the OpenAI angle and ask: Is this a fair price for a renovated 1,800-square-foot flat in this neighborhood? If the answer is no, the lore won't save you.
- Liquidity matters: A famous-address premium, if it exists, depends entirely on finding another buyer who values that story. That's a smaller pool than the general market, which can hurt you if you ever need to sell quickly (and if you overpaid).
- Landmark designation isn't always a good thing: If a property is ever formally designated as historically significant, that can limit what you're allowed to do with it — renovations, additions, even certain repairs can get complicated. It's worth understanding the risk before you buy (10).
The OpenAI apartment checks out on the math front — the pricing seems reasonable for the neighborhood. Rather than trying to increase the property's value, the real estate agent seems to be using the story to generate interest in the listing.
But if you ever find yourself tempted by a home based on who used to live there (or what was filmed there), make sure the story doesn't distract you from what matters — can you afford the home and would you want to live there?
