Grenades can hurt you if they explode on the other side of the wall you are close to. It works this way with any wall, should it be outdoors or as part of a house. This makes the use of grenades to clear houses rather unpractical.

Throw a grenade on one side of a wall, place yourself on the other side and wait for the explosion.
Tested today. It seems to be working well with any buildings or walls made of stone, bricks or concrete. :)
The only buildings where I experienced splash damage through the walls are the small metal and wooden sheds, but I reckon that's how it's supposed to be.
