Do I really need to fill up the tank before the 2016 CRV goes into a warm shop for a couple hours?

I grew up in upstate NY where 1) it gets really cold, and 2) my cars never saw the inside of a garage, heated or not. I was always told to fill the tank before bringing the car into a warm building. However, I never had direct knowledge of anyone with a frozen gas lines.

Flash forward to the present. I live in eastern IA, have an attached (but not heated) garage, use regular with 10% ethanol, and in winter months my CRV is rarely parked outside for more than a couple hours. However, next week it'll be in a heated shop for a couple hours. It's on half, I'll probably top it off just to be safe.

No.

Think about it like this: Those who have heated garages drive in the cold weather, park outside at work, drive home and park in the heated garage again without a problem.

You won't have a problem, either.

No. In Alaska (ethanol free gasoline state), my truck would spend at least 10 hours per day in the parking lot at work, and then would spend the night in my heated garage. At least once a month, it would spend a week parked at the airport and then be parked in my heated garage. Zero condensation issues causing freezing.

If you already have water in your gasoline, your solution should be different.

Once you get it back, fill tank and add some gas line drying additive, they remove moisture from tank and gas lines. While we don't get super cold (30's) in my area we do get cold snaps (lower teens) the stuff helps. Chris

Absolutely no need to add HEET to the tank if his gas contains 10% ethanol.

Yeah, ethanol made HEET obsolete.
Is it possible you got some bad fuel?
