Quick question before I head out...
I'm doing an ec for a brick crawlspace house that has been converted to a duplex. One on the left and one on the right.
While my client only owns one side, I assume I need to measure and include the entire structure?
Also, assuming they don't have adequate venting(built in the 40's), if they want to lower their rate, they will need to add vents to properly vent the whole house--probably from just their side.
Now that I write this out, I believe that regardless of what they own, the ec needs to be for the entire house.
Thanks!:-D
Great question. I believe you are correct as a flood event will be affected by the structure as a whole.
I have never had a call for an EC on a duplex. That's hard to believe now that I think about it.
Yes, the entire structure is involved. Say you got called by the owner of each side one month apart. On one side there is more than adequate venting for the entire structure. On the other, there is none. The first side is going to keep the other one from having a problem. Or, is it? You could have an identical situation on the structure if it was still a single family style above that crawlspace. Ours is to gather the facts and report them. Ours is not to do an indepth structural analysis of what might happen if one half is vented and the other is completely sealed off.
Floods are like fire. If it happens to one end of the structure, odds are high it will happen to the entire structure.
Now, tell me how to rate one where one end of the crawlspace is 10 feet high and the other half is sitting on a concrete floor.
I've read in the technical bulletins about townhomes or "row houses" and Each unit needs adequate venting for the enclosed space that they are using the form for.
