A house that once symbolized TV’s most wholesome blended family is now officially part of Los Angeles history. The Los Angeles City Council voted Wednesday to grant Historic-Cultural Monument status to the iconic “Brady Bunch” house, cementing the famous TV home into the city’s history books after a vote held before a packed chamber at City Hall. The modest mid-century split-level ranch house at 11222 West Dilling Street in Studio City — often described as the second-most photographed home in America after the White House — will now officially join Los Angeles’ list of protected historic landmarks.
