ORIGINAL 5:55 AM REPORT: Big response to a house fire in the 4200 block of Beach Drive [map]. More shortly. 6:15 AM: Beach Drive is blocked off from La Rustica to Me Kwa Mooks because of the callout, which is – as noted in comments – at an under-construction home on the water side of Beach. 6:21 AM: The fire’s tapped. Fire Department spokesperson Helen Fitzpatrick is there and confirms that nobody was inside at the time and that no one’s been hurt – the fire appears to have originated on the second floor; they’re trying to reach the building’s owner. 6:26 AM: Note that the Beach Drive closure is affecting the 37 bus – via Twitter, @crm4444 advises that it’s being rerouted up Jacobsen and, “Looks like 37 riders north of Jacobsen need to catch at 63rd/Admiral till fire action clears.” 6:59 AM: Adding video of ladder crew working once the flames were out. When our camera pans back to the truck, you can see why the entire road is closed at that spot:
No word yet on the cause. 7:06 AM: SFD spokesperson Fitzpatrick now says one firefighter suffered an arm injury and had to go to the hospital. 7:18 AM: Heading back to the scene for an update. Beach Drive is still closed at Weather Watch Park on the north side. 8 AM: Still closed both ways; incident commander at the scene tells us northbound Beach Dr should reopen within an hour, southbound (the side the burned house is on) will be a bit longer. No word on the cause yet; investigators are in the house now:
In the daylight, it’s clear that the new construction where the fire happened is actually a two-story add-on in front of the old house.
10:30 AM UPDATE: Investigators say this was an accidental fire – damage estimated at $250,000. SFD says they haven’t zeroed in on exactly what sparked it, but it’s clear it was not deliberately set, so that’s the ruling.
