# Default values

When we know the likely answer for a question, populate it as a default value.

In the Apply for a building permit form, we set City = San Francisco and State = California for the street address of the project.&#x20;

These should be used rarely, but they can be helpful for City, State, and Country.

### Dynamic values

As our form platform evolves, populating fields based on other inputs will make the form easier to fill out. For example, populating City based on your Zip code.&#x20;

These features should be tested as we build them to ensure they don’t creep out our users.<br>
