It's not the biggest house. In fact it is a small as fuck house, but there's no way in any capacity that Todoroki is not going to cram all three of them in there gladly. He has taken Izuku in for a while, he's taken with the idea of his living room being an extra room, and he honestly doesn't use his kitchen that much that part of it can't have a cot of some sort he can sleep on in there. That way, too, he can wake up when others do to help around the house.

A house he will be looking to get a bigger one of. But it does keep him busy arranging the rooms and considering what they might do to better accommodate all of them until he gets something bigger. "You can stay in here for now, Midoriya, it's comfortable, the couch is there and you have room for things in it. Bakugo, you can take Midoriya's old room for now. I'm already looking into a larger place that'll help all three of us stay together." Which doesn't sound so bad for now to him, there has been so many situations that he just doesn't want to think about where staying together is the better option.
