I been on the fence about converting my home to rent and possibly moving out. After reading and article and watching a video, I recorded I do want to convert 2 story home into 2 units, my current property already is 3 units.
1 unit x 2 story home (2/2 bottom, 3/3 upper) 

2 units x 1/1 (duplex)

Property already have 4 gas meters and 4 electric meters because the 4th meter is for laundry use but currently not in use. 

Which is the correct permit to apply?  https://www.ladbs.org/forms-pu...
