Windows At The Top Of Stairway

Most building codes state that any windows that are within a 60 inch width by 60 inch height area, from the last stair tread, shall be made using tempered safety glass.

Special Tip: The biggest problem in a situation like this is when a builder isn't familiar with this stair building code, orders standard windows within this area, only later to find out by the building inspector, that these windows need to be tempered glass. Problems like these can cost builders lots of money.
