Last night, tipster Ramón B. alerted us to a fire that broke out at 260 Castro St. (between Beaver and 16th) at around 9:30pm.

"The façade of the house sustained fire damage and some water damage, but it didn't lose power," he said. "SFFD can determine the cause, I'm not certain. The property was recently sold."

According to a tweet from San Francisco Firefighters Local 798, the blaze began as a  grass fire, then spread to the structure.

#Fire right now on 16th and Castro. Grass fire spread to 260 Castro. Crews on scene right now. @nbcbayarea @Scott_Wiener @breakingsfnews
