The permit applications can be processed electronically with payments made via credit card. Note that an online payment and submittal does not guarantee the automatic issuance of a permit, as the application is subject to a review and approval process.

Important: To protect the security of your information, you must have a current or nearly-current browser and operating system. If you do not, the online payment portal will not allow you to submit a payment. See our Supported Browsers and OS page for more information.
