Did the Harts live in Bel Air or Beverly Hills ?
Bel Air. The address used on the show is 3100 Willow Pond Road, Bel Air, CA.
But the house used for exterior shots is actually in Brentwood, CA. It was once owned by June Allyson and Dick Powell who were friends of Aaron Spelling and Robert Wagner.
June guest starred as Elizabeth Tisdale (Max’s pen pal) in S5 E21.
Also, I'm still a bit disappointed that one of the recent owners had the pool filled in with cement.
