Is man door reqd at attached garage for single family R-3?

[addtext]

I wanted to ask if there is any code requirement for single family
home attached garages to have a door from the garage to the exterior?
I would like to remove the man door (34" x 6'-8") in our garage and
use the wall space for shelving. If so, then there would only be the
garage door for getting outside or going thru the house to the front
door. Does an attached garage require a man door to the exterior?

Jerry,

My MA code book, which is same as 2003 IRC states that a dwelling unt requires two means of egress and that the secondary means of egress may be through a garage provided the entry door to the the garage and exit door within the garage are a minimum of 32 inches wide and meet other requirements within code.

You may have answered this person in error, if locking or removing the door does not provide two means of egress from the residence.

Jerry,

Here's the MA code section:

5311.4 Doors

5311.4.1 Exit Doors Required.
"Egress from all dwelling units shall be by means of two exit doors, remote as possible from each other .........."

5311.4.2 Exit Door Types and Sizes.

The minimum nominal width of at least one of the exit doors required by 780 CMR 5311.4 shall not be less than 36 inches (914 mm) in width and the minimum height shall be 6 feet, eight inches (2032 mm). The 36 inch (914mm) exit door shall be side hinged. All other required exit doors and doors leading to or from enclosed stairways, or to interior vestibules shall not be less than 32 inches (813 mm) in nominal width or less than six feet, eight inches (2032 mm) in nominal height and may be of the sliding or hinged type. The 36 inch (914mm) required exit door shall provide for direct access from the habitable portions of the dwelling to the exterior without requiring travel through a garage. The 32 inch (813 mm) secondary exit door may provide egress through an attached garage, provided that the attached garage is also provided with a 32 inch (813 mm) exit door meeting the requirements of 780 CMR 5311. ........."
