Threshold for Condo Slider

Haha yeah, are you asking about the outlet or the door itself? Kidding, by the thread title you're obviously talking about the "step to get over the threshold onto the balcony. It in an accessible unit? Is it a required means of egress? Does the balcony connect to anything else? And are you asking if it would be compliant under the current code or compliant at the time it was built?

Type B units are allowed to have an impervious balcony surface down 4 inches from the floor, but the threshold height is limited to 3/4 inch in 2009 A117.1 1004.5.2.2.
 
I worked on a lot of high-rise apartment buildings in the 70's and 80's in Dade a Broward County and do not recall ever having to step over a threshold like that. However, Palm Beach County was under the SBCCI, and local jurisdiction could have many amendments to the code.

I guess you have a lot of research to do to determine if it was code compliant at the time it was built.
 
The way I would look at it, the area on the inside of the door is now a step. Is the "step" wide enough? It doesn't look like it is.
 
This is most likeley replicated many times in the building. If the end product is 7-3/4" or less, there is no code violation. And even if there were, it is too late to get it corrected. As long as the new threshold is no worse than the existing, I don't see a way of changing anything without a potential bigger problem.
 
2018IBC .1.7(2) If its a type B unit: I would think with the 4-inch or 4-3/4" threshold in an area with windblown rain would be needed to keep standing water from seeping in through the patio doors weep holes.

We have an issue when a 4"-plus snow melts next to a patio door here, it sometimes will inter through the weep holes.
