An official music video was released for the song "Chem 6A". In 2009, it was published on the official YouTube channel of EMI. As of February 19, 2014, it has had over 66,000 viewers.
In 2004, Switchfoot released a 3-CD compilation entitled The Early Years: 1997-2000, which encompassed their first three albums, including The Legend of Chin. In 2008, "Concrete Girl" was included on the band's greatest hits collection, The Best Yet, and "Chem 6A" was included in the Deluxe Edition Bonus DVD of The Best Yet.
While the album never officially charted on Billboard, tracks from Legend of Chin contributed to late 1990s' pop culture and were revitalized on subsequent Switchfoot projects. Most notably, the song "You" was featured on the soundtrack of 2002 movie A Walk to Remember, starring Mandy Moore.
The album got a positive review from Billboard, which called it "An intriguing and surprisingly mature effort for a debut release."
Mike Rimmer of Cross Rhythms rated the album 7/10 and wrote, "They may have taken their name from a surfer buzzword but this ain't no Beach Boys album. Instead, a melodic modern rock style reveals some nifty crisp guitar sounds, raspy vocals and a smattering of memorable songs and there's the problem. So much of this still washes over me and despite the fact I've played it about 15 times, it's still barely getting my attention. (...) Sonically this sounds like a great album - all the right ingredients are in place, but like a good Yorkshire pudding, even the finest ingredients won't be enough if it doesn't completely rise! There are moments when this one is more pancake than pudding. However, overall worth checking out."
