 That Gorge Jakubec could amass weapons on such a large scale in Escondido, California is not surprising.
(Being surrounded by military bases filled with young and poorly paid people in a glamorous environment makes it easy to get almost anything on the black market. Sometimes the temptation is too great to resist for the young and impressionable.)
What is surprising is that the guy lived in the building with these explosives.

Judging by police photos -the guy could have used the help of Niecy Nash and her Clean House crew.
