#Q ORIGINAL QUESTION

Is the firehouse in The Princess Diaries a real residence?

What a correct answer would look like:

Yes, the firehouse in The Princess Diaries is a real residence located at 724 Brazil Avenue in San Francisco's Excelsior District. Historically known as Engine Company No. 43 (built in 1911), the building was decommissioned and sold in 1976. While the exterior shots in the film are of this actual building, the interior scenes (including Mia's apartment) were filmed on a soundstage at Walt Disney Studios in Burbank. Contrary to the film's cluttered, colorful set, the real interior is minimalist and modern, though it does retain a real fire pole, which the current owners use. The property last sold in 2015 for $1.85 million.

What the LLM said (errors and omissions annotated)

Yes, the firehouse featured in the 2001 film The Princess Diaries is a real building and a private residence in San Francisco.

Here are the specific details regarding the property:

#F CORRECTION FEED (CLICK TO SEARCH)

[1] The building is a real private residence located in San Francisco.
[2] The address is correctly identified as 724 Brazil Avenue in the Excelsior District.
[3] Historical records confirm it was Engine Company No. 43, built in 1911.
[4] The firehouse was decommissioned and sold at auction in 1976, becoming a residence/studio.
[5] Filming locations confirm exterior was San Francisco, interior was Disney Studios Stage 2.
[6] Production notes indicate the set was designed to look like a converted firehouse, though the style differed from the real interior.
[7] The fire pole scene is a well-known plot point.
[8] While the statement about removal is generally true for converted firehouses, this specific residence *does* retain its fire pole, which is a key feature mentioned in listings.
[9] It remains a private home and attracts tourists.
[10] The property sold for $1.85 million in 2015. This is not 'several million' (usually implying 3+), and 2015 is over a decade ago.

#O MISSED POINTS & OVERSIGHTS

Medium
Specific Sale Price

The summary vaguely claims 'several million' when the actual price was $1.85 million, which is significantly lower than 'several' implies.

Low
Real Fire Pole

The summary implies the real house likely doesn't have a pole ('often removed'), but it actually does.
