# How to sign a permit category or request changes
TIP
Category signoff users can only review categories that they are assigned to.
TIP
Permits categories can be reviewed in the Pending category signoff stage by the relevant category sign-off user. They can also be reviewed in the Pending signoff stage by the overall permit sign-off user.
- Find the category you want to review
Follow the instructions on how to view a permit.
- Approve or Request changes to the category
From the Categories drop down, click on the category you want to Approve or Request changes. From the dialog, you can:
Click the Approve button sign the permit category.
Click the Request changes button reject the permit category.
In both cases you can add an optional comment, which can be used to give context to your decision.
