Codes & Standards Discussion Forum 

Welcome to the ICC Codes & Standards Discussion Forum

The Code Council has revisited how best to provide an online, professional Discussion Forum and area within the website that has a sense of community – where Members and nonmembers can provide input and exchange ideas with their peers in the industry. The new Codes & Standards Discussion Forum does just that, as it allows Registered Website Users and ICC Members to discuss the I-Codes in an online community.

If the only egress is the garage door, we require at least one ''man'' door, either back into the house, or, if detached, to the outside. Typically garage doors don''t count as egress doors. Most owners install one or the other. If the garage door is power operated and the power goes out, they still want a way to get into the garage.

Though I see no requirements for an egress door from a garage in the IRC (attached or detached).

If the garage is attached to the house we do not require a door to the outside. If the garage is detached we require one hinged door.

Per cbo_3050, a garage isn''t a habitable space and I don''t think the IRC requires an egress door.

As an architect, I always include a "man door" anyway on the assumption that a homeowner would always want one for functional reasons. Either into the house if attached, or onto a breezeway or stoop if semi-attached or detached.

However, since it isn''t a required door, I don''t necessarily follow the requirements of the one egress door required in a house. It may be 32" instead of 36", for instance, or may not include a landing.

Do you mean if the garage is attached to the house AND has a door from the garage to the house? Is there a UBC code section that requires an egress door from the residential garage? Thank you.

You have to walk through the code a little, however an exit door(man door) is required for attached or detached garages.

CBC 1003.2.1.1 The building official shall assign a category as set forth in Table 10-A to all portions of a building.

CBC Table 10-A Residential garages are not specifically listed, therefore they fall under item no. 30 "All others" which requires two exits if the occupant load is over 50. Obviously the occupant load of a residential garage is lessthan 50, as such only one exit (man door) is required.

CBC 1003.3.1.2 prohibits the use of an overhead garage (vehicle) door as an exit.

Have fun.

P-wood, I don''t see any egress requirements for a U-1 occupancy, does a U-1 occupancy actually have an occupancy load? and would it fall under 1003.3.1.2?

Beach,

In order to determine exiting requirements per CBC Chapter 10, you need to begin withsection 1003.2.1.1 "The building official SHALL assign a use category to all portions of a building.... When the intended use (ie garage) is not listed in Table 10-A, the building official SHALL establish a use based on a listed use that most nearly resembles the intended use."

You could use dwellings or parking garages or "all others" to assign the "use" to your residential garage.

CBC section 1001.1 "Every BUILDING or portion thereof shall be provided with a means of egress as required by this chapter."

It seems clear to me that a garage (whether attached or detached) is a building and requires a means of egress (man door).

Have a good weekend.

Scott

scott,
i see 1003.3.1.2 and i think it says an overhead door is o.k. for egress as long as the occupant load does not exceed 9 occupants and pherhaps a dog [IMG]http://www.iccsafe.org/ubb/biggrin.gif[/IMG].am i missing something here?

P-wood

You are correct, kind of you to point out the error of my ways. Should have read a little closer and saved myself some time.

Have a good Monday.

Wouldn''t the next paragraph "Manually operated horizontal sliding doors may be used when serving an occupant load of ten or less." mean a garage could not have ONLY a standard sectional garage door with an electric opener? Or does that paragraph pertain to something else because the first paragraph says"....occupant load of ten or more..." and the second paragraph says"...ten or less...." it''s getting confusing!

What about storage units with typical roll up doors? Those are lined up side by side and back to back, how many plan checkers make the architect add "Man doors"?

According to page 90 of the 2000 IBC Nonstructural Q & A - Application Guide, ICC is of the opinion that an overhead garage door can be used as an exit from a residential garage.
