Re: Parking distance from exit door
Not sure about the 15 feet, but I would say at least 10 feet is required bu following the intent of the definitions of Chapter 10 for MOE.
EXIT DISCHARGE. That portion of a means of egress system
between the termination of an exit and a public way.
PUBLICWAY. A street, alley or other parcel of land open to the outside air leading to a street, that has been deeded, dedicated
or otherwise permanently appropriated to the public for public use and which has a clear width and height of not less
than 10 feet (3048 mm).
The definition states clear width and height - it does not state from the building, building materials, etc. A parked car located near the exit door may be an obstruction to the exit discharge is less than 10 feet.
OR
The fire chief has concerns about the ability to ladder the building. Depending upon the eave/roof height, will depend on how far from a building a ground ladder has to be placed for the (safe) proper climbing angle of about 70 degrees. - for instance, a 24 foot roof height will require approx. 9 feet for the foot of the ladder and add three feet for personnel to be able to move onto the ladder safely. this equates to about 12 feet for a 24 foot tall building.
The first answer is code based, second answer is common sense based.
Some times the term authority has jurisidiction interpretation is a rendering of ruled based plus common sense application.
