Egress Window Requirements for Montgomery County Basements

The Basic Job Of An Egress Window

Clear opening size, not just rough frame size. Sill height, which is often the detail that gets missed in older basements. The sash should open from the inside without keys, tools, or a complicated sequence. Window well access, including enough room to climb out if the basement sits below grade.
