“Dear PoPville,

I want to put an addition on my row house. I know popups aren’t popular these days, but I’ve wanted one for 15 years and never had the money. I want to do it before the regulations get any tighter, so I’m trying to move quickly, but my cash is tight. I have a background in construction and want to do all of the work myself. I’d like to know what the absolute minimum requirements of licensed professionals would be in order for a homeowner to get a permit to build an addition. For example does a licensed architect need to approve the plans? A structural engineer? What requirements are lessened for a homeowner working on his own property?”
