The only justification that I can think of is that it would prevent little kids who are home alone from opening the door by themselves.

It also prevents a thief from punching out one of those side skylights and unlocking the deadbolt.

I heard that before. Not sure what the code is on that?

International Residential Code 2015 (IRC 2015)

R311.2 Egress Door

Not less than one egress door shall be provided for each dwelling unit. The egress door shall be side-hinged, and shall provide a clear width of not less than 32 inches (813 mm) where measured between the face of the door and the stop, with the door open 90 degrees (1.57 rad). The clear height of the door opening shall be not less than 78 inches (1981 mm) in height measured from the top of the threshold to the bottom of the stop. Other doors shall not be required to comply with these minimum dimensions. Egress doors shall be readily openable from inside the dwelling without the use of a key or special knowledge or effort.

Do IRC's supersede local, state or national codes?

No. but virtually all residential construction must adhere to comprehensive building codes and standards governed by local and state laws. Because of the cost and complexity of developing and maintaining such codes, state and local governments typically adopt nationally recognized model codes, often amending them to reflect local construction practices, climate and geography. Most U.S. communities adopt the International Code Council’s I-Codes for this purpose.

The issue with the double cylinder deadbolts is that there is controversy on what the code actually says.

Not less than one egress door shall be provided for each dwelling unit.

Some feel that code allows double cylinders on egress doors as long as there is at least one without them.

Some feel that all doors leading to the exterior are egress doors and cannot have double cylinder deadbolts.

The code itself has not specified.

And there is no law that stops a homeowner from doing this. It may be against code, but there is no recourse to the homeowner, unless he requires a building inspection.

A locksmith or licensed contractor cannot install them, or they will get fined.
