I wanted to install an on-demand water heater when I built this house in '85. It was the only red ink on my blueprints. (most architects plans look like someone bled out on them) I had a window too close to where it needed to vent and didn't want to give it up so I went with a conventional tank heater.

Ah, I had to look that one up.

From this I understand that this was the only modification to your home's original plans. Am I correct?

Yes, that was the only thing the county building department didn’t approve of in my blueprints. I used to build houses and I’ve never seen a professional architect’s plans that didn’t have loads of red penned corrections on them. I also had my plans approved in exactly 7 days. I felt pretty good about my first set of drawings. No computers with CAD software either.
