All his adult life, Pflueger maintained his residence at his childhood home on Guerrero Street. When entertaining downtown late into the evening, he was known to spend an occasional night at the Olympic Club. Pflueger drove a green Cadillac convertible and was often seen with his steady lady friend on his arm. Pflueger never married and left no children. His brother Milton, fifteen years younger, had been working with the firm since the 1930s and, at Tim's death, Milton reorganized and headed the company, doing business as Milton T. Pflueger, Architect.
