The restored firehouse at 3816 22nd St. has been on the market before, from 2008 to 2010 (back in the economic slump when it was more difficult to sell a property—you know, in the days when falling down shacks weren't bid up). Back then, we wrote about it in pretty laudatory terms, using phrases like "kind of gorgeous" and "definitely tricked out" and even "stunning-ass house." In those dark real estate days, it started at $6.375 million, but after three years the price was slashed to $4.8 million. Now it's back on the market and a lot of things are similar. For one thing, its asking for $6.898 million. For another, this is still a stunning-ass house. Engine 44 started life in 1909 as a fire station that served Noe Valley and the Castro. It was remodeled as a private home in 2007, but it retains some scraps from the old days: the brass fire pole, copper stable doors, and zinc doors. Those old features are surrounded by modern fabulousness.
