DIF Deferral Agreement Fee

Levied by City of Ontario on new development in Ontario. Authorized under the Mitigation Fee Act - Gov. Code Sec. 66000 et seq. Collected other: at submittal of the DIF Deferral Application — the application is not accepted for processing without it.

Not priced for this house. This charge is real, adopted and collected, and it is left out of Ontario's figure for one reason: it is levied per agreement, and a typical home does not fix that quantity. That is not the same as a zero. The fee is owed; what is missing is the number to multiply by, and inventing one would price this house with more confidence and less truth. Every published rate is in the table below.

About these figures

Quoted, not summarized. Every amount and fact on this page is copied from the official document it links to. If we couldn’t find something in a document, we leave it blank instead of guessing.

Before any discounts. Some fees offer credits, waivers or phase-ins. They’re listed above but not subtracted, because whether you qualify depends on your project.

Check the date. Fees change. This page shows what was in force on the date at the top, with a link to the document that set it, so you can confirm the current amount yourself. How all of this is put together.
