Electrical updates for 2 unit homes, AFCI, federal pacific

[Mike Goikhberg]

I'm soon closing on a 2 unit property in the city. The property has two separate panels, 150amp each. They are the older federal pacific stab-lok type. No AFCI. I plan to get it rezoned to multifam, and get the use n occupancy permit. Does anyone have any experience with the rental inspections for that permit with respect to the electrical? Should I install AFCI breakers and update the panel?
