Travis County uses an online platform to process development permits.

Once you complete all previous steps, please proceed to create a permitting account.

Once your account is created and phone number verified, you can move on to filing your paperwork.

Please have all the requirements in previous steps handy.

Start your online application.

Follow the instructions and steps provided within the platform.

In the “Select an Application Type” step, select “Development (Non-Residential)”.

NOTE: If you also need a Development or Driveway Permit, you must submit for your OSSF Permit as a separate application.

As we review your application, you can track the progress in the permitting website.

All communication associated with your permit application will be conducted within the same website. Please monitor your email and queue for status updates or comments associated with your application.

If the County has provided comments on your application, action is required by you to address the comments. The review process will be paused until you have responded sufficiently to each comment.

Once your application is approved, you will receive an e-mail notification.

Post the permit somewhere visible from the public right of way (ROW) on your work site before you begin your project.
