    4. General Requirements for Electronic Plan Review

    Plan reviews to DIS must be submitted electronically through the Electronic Safety and Licensing Application (eSLA). DIS no longer accepts hard copy plan review submittals. Note the following requirements for eSLA:

    • The applicant must create an eSLA login profile. This login profile is specific to the individual submitting the application. It should not be a generic profile for the company. (UDC permits and plan reviews are not submitted using an eSLA login. See the UDC program page for more information.)
    • If a Supervising Professional is required, the Supervising Professional must also have an active eSLA login profile.
    • You must include the property owner's name, address, phone number, and email address.
    • eSLA works best with Google Chrome, Mozilla Firefox, or Safari as the internet browser. If using another internet browser, you may experience technical issues with the submittal.
    • Be able to combine plan sheets into one file for upload.
    • Be able to combine supporting documents into one file for upload.
