That "1.240 million" is all fires, including vehicles & outside fires. I freaked out a bit thinking 1% of all US homes catch fire every year.

It seems 31.7% of those were "residential" fires (393000).

From https://www.usfa.fema.gov/downloads/pdf/statistics/v17i2.pdf:

From 2012 to 2014, fire departments responded to an estimated 243,800 fires in one- and two-family residences each year across the nation. These fires resulted in an annual average of 2,110 deaths, 7,950 injuries, and 5.4 billion dollars in property loss.
