Wow!! New Whiz Kids (Les Petits Génies in France) location video just dropped today from Christophe Minguet's channel EloChris Travels. 
It even goes into Canyon High School...looks like the computer lab is still the computer lab...although I'm sure they don't call it that anymore, I guess it's just the library.
The house where Richie lived (Calabasas, California) as well as the school (Canyon Country suburb) is still under a level 2 evacuation warning (be ready to evacuate if the order is given).
