Each line is the one rate this home pays. Most fees publish several rates — by house size, lot, or location — and only one applies. Click a fee for its full schedule and source documents.

Published rates that could not be converted

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.

Percentage surcharges

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

Housing and in-lieu options

Paid instead of building something — affordable units, for instance — or measured on something the figure above does not assume. An alternative, not an addition.
