Building Permit Glossary
Permitting has a vocabulary of its own, and most of it is never explained to the people who have to use it. These are plain-English definitions of the terms and documents you will meet applying for a building permit.
Every document entry also says where in the permitting process it applies, because the useful question is rarely just what something is. It is when you need it, and whether you are already late.
The permitting lifecycle
Nearly every permit follows the same seven phases, whatever the jurisdiction calls them. Document entries in this glossary are placed against these phases, and a document often applies at more than one. Select a phase to see only the terms that apply there.
