window height from floor?

I was doing a mock inspection today and came across a bedroom window on the second story that was only 12 inches from the floor. The window didn’t seem to be at a safe distance and I cant find anything saying what he industry standard would be. anyone dealt with this before?

  1. Operable windows with openings that will not allow a 4-inch-diameter (102 mm) sphere to pass through the opening where the opening is in its largest opened position.

  2. Operable windows that are provided with window fall prevention devices that comply with ASTM F2090.

  3. Operable windows that are provided with window opening control devices that comply with Section R312.2.2.
