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.
