Client Assistance Memo (CAM) #101, called "Getting a Single Family Building Permit from DPD" is a good resource to help you get started.

Also, just about every DPD permit requires that you fill out our Statement of Financial Responsibility / Agent Authorization form if any person other than the owner of the property will be assisting in the permitting process. Please make sure you have those forms completed before you arrive for any scheduled appointment about your project.
