Is there any way around putting a heat source in every bedroom?

I was speaking with an HVAC guy in my area today who reminded me that code says we have to have a heat source in every bedroom. We're planning on putting a single head ductless minisplit in our 1450 sf high performance home (to be built next year). Are there other exceptions/solutions out there, or do I just stick a Cadet heater in every bedroom and disconnect them after the inspector checks it off his list?

Blown Insulation

Hello, we have a bonus room over the garage that does not have an attic. The ceiling of the bonus room is drywall, studs, then roof. The ceiling goes to an angle, then across to the other angle to create a ceiling that looks like the letter "A". I took out the middle line of the "A" and noticed the insulation had been tamped down by a previous owner's rodent problem. I am wanting to blow in insulation between the ceiling and the roof in between the studs, but I am not sure if I will have a moisture problem. Is blown in insulation the way to go?

Structural Wall

My husband and I are looking to take out a small "lip" of a wall and aren't sure if we can do so. Let me post a picture:

Also, I don't think we can take out what I labelled as "possibly this" because I think it's a beam, but I'm not sure. If we can, I'd like to.

As for what's in the basement underneath, here is a picture that faces the same way:

Does OSB sheathing need to be installed horizontally over advanced framing studs 24"OC?

A client building in Zone 4 says their engineer told them, "in our wind speed and exposure (105mph - C) neither OSB nor 15/32” CDX can span between studs at 24”oc without being run horizontally". This is problematic because they are not planning on using rigid foam over the sheathing and are concerned about increased thermal bridging and air leakage resulting from expansion joints and additional blocking needed for horizontal installation. I have seen many houses with vertical OSB sheathing over 24" OC studs so this is new to me. Has anyone else heard of this?

Squat toilet: Alternative minimalist design?

The squatting position is thought by many to important benefits over what we might consider a modern civilized toilet to be.

Are squat toilets now code approved in the US?

If so,they are in my Western eye unsightly and create an undesirable contour in the floor. That said is there a way to help make sure this flap drain doesn't clog if one daily toes a duty down the lifted grated drain during a 15-20 gallon shower? Is there a way to purpose the shower water into a flush? for the drain?

Masonry pier foundation — Code does not allow appropriate depth?

Hi all, I hope I am interpreting this wrong or missing something but it would appear that the Minnesota residential building code does not allow a masonry pier supporting a wood girder for an exterior load bearing wall to be deeper than 4 ft from top of footing to sill plate. The minimum frost depth is 60" here (Duluth, MN) for footings. Am I missing something?

Hi, does anybody know about bipolar ionization?

I would like to know if anyone is familiar with this process in residential construction and if it is accepted by building depts in the US. If accepted how does this change the amount of fresh air that is needed to be brought into a tight super insulated home? Thank you.
