Rating of Door to High Rise Condo

[jar546]

You have seen this before on another thread. Here is a new twist on that old thread.

The owners want to replace the double entry doors. Do they need to have any fire-rating?
This is a Type 1B Sprinklered building.

In general without info

It is a high rise, doors should be rated.

Plus elevator lobby


I forgot does the building have a fire sprinkler system?

 

[Mr. Inspector]

Yes if it is a Fire Service Access Elevator.

 

[jar546]

The elevator only serves the condo on that side only with access to the stairwell. When you get off the elevator you can either enter the condo or go through the exit door to the right and down the stairwell. The elevator space essentially belongs to the owners similar to a foyer.

I thinking it would have to be rated.

Are the entry doors, to the unit rated???

 

[jar546]

Rated to what?

 

[cda]

20 minute minimum, maybe higher

 

[Builder Bob]

Need to go back to code building was constructed under, Current code could be questionable as the occupant load of the elevator lobby is minute compared to the size of the dwelling unit. If the dwelling unit is the complete floor, I would advocate that the dwelling unit door may be unrated since rated corridors/ etc. are not required. The doors to the elevator lobby may require a rating in accordance with current codes.... but this is mixing and matching existing codes to new codes.

What was the scope of permit and what codes were applied at time of application - if IEBC Alteration, then need to research code building was originally constructed or look at original blueprints for building. If new codes were referenced, need to follow requirements for elevator lobby if required.

Look at the doors. Are they labeled? If yes, then replace them with doors of equal rating.

¿¿Unless someone replaced rated doors, before with unrated doors.???

Ok, here is a thought, may be a bit of a reach though due to limited information available.

If the elevator is a fire service access elevator (IBC 3007), then the following applies:

3007.6.2 Lobby Enclosure
The fire service access elevator lobby shall be enclosed with a smoke barrier having a fire-resistance rating of not less than 1 hour, except that lobby doorways shall comply with Section 3007.6.3.

Exception: Enclosed fire service access elevator lobbies are not required at the levels of exit discharge.​

Continuing onward....

3007.6.3 Lobby Doorways
Other than doors to the hoistway, elevator control room or elevator control space, each doorway to a fire service access elevator lobby shall be provided with a 3/4-hour fire door assembly complying with Section 716.5. The fire door assembly shall comply with the smoke and draft control door assembly requirements of Section 716.5.3.1 with the UL 1784 test conducted without the artificial bottom seal.​

As it is a level 1 alteration....

If it were level 2:

805.5 Openings in corridor walls. Openings in corridor

As usual, "it depends"
