San Francisco's current dry, sunny weather is certainly enjoyable! But it also might be partially to blame for two recent fires: one that hit Union Street early this morning, and another that hit Castro Street Saturday night.

Hoodline reports that a home at 260 Castro Street started burning at around 9:30 Saturday night. The single-family home, which is located near Corona Heights Park just a few blocks from the California Pacific campus, was built in 1927, according to Trulia. It's valued at an estimated $1,742,000.

According to a tweet from Local 798, the union that represents San Francisco's firefighters, the blaze was caused by a dry-weather grass fire that jumped to the residence.

No injuries were reported as a result of the blaze. According to a witness who spoke to Hoodline, "The facade of the house sustained fire damage and some water damage."

At around 3 a.m. Monday, SFFD was back on the flame-fighting job, this time further east. That's when, according to fire officials, a 20-foot-by-20-foot roof deck on an apartment building at Union and Taylor streets went up in flames

The two-alarm blaze damaged the upper units in the building, KRON4 reports, but no one was injured, according to CBS5.

Fire officials say "anything from a lit cigarette, to a grill that wasn’t turned off" could have started the blaze, and that "as the weather gets nicer, more people are spending time on their decks, and need to be vigilant of fire hazards."
