Online & ePlan Applications

Online Application System

All users may fill out an online application by electronically entering information on an online form, as opposed to handwriting the information on a paper application. Once the application is completed, one of the following must be done for the application to be processed: continue the process by bringing paper plans to the Permit Center for review; or continue the process by submitting digital plans online through the ePlan system, which is more convenient. You will receive an email from "" with instructions on how to upload your plans; please remember to configure your email spam filters to accept email from this address. An "ePlan Applicant Quick Start Guide (PDF)" is available, as well as an "ePlan User Guide (PDF)."  If you need assistance, please send an e-mail to
