These are real charges. They are left out of the figure because they cannot be worked out per house without knowing something this site does not assume — a percentage of another fee, a per-room count, a per-application charge.
Charges that are not part of the one-time total above: fees set as a percentage of another fee, and payments a builder can make instead of building something. Neither is added to the headline figure, because neither is a fixed amount every new home owes.

No percentage surcharge is recorded for Los Angeles County (unincorporated).
