Sean,
Permit me to completely endorse the previous comments from Brett and Chris.
Let me also add this - there is great value when someone is asking for a
design which is both contrary to the applicable standard, and does not
address the possible concerns for a fire in the occupancy in question,
by asking them to 'put it in writing' and affix their signature.
Immense power for you in that.
I would go one step further, and note my concerns such as those raised
by Brett and Chris, and ask for guidance in writing.
hope this helps,

I have an interesting situation here: A homeowner has an electric car and an electric car
charger in her garage. However, the house is not sprinkled and she is asking to just
sprinkle the garage only. The AHJ has even pre-approved just protecting the garage only
and not the entire residence. No problem, right ? Well, I don't know, TBH. There is a
3/4" water line that COULD feed these 4 or 5 heads, but under what code reference
would you apply here ? Since this would have been a 13D system to begin with, could you
have just put in a few concealed residential heads and connected to the 3/4" water
line ? All the AHJ has asked for is to draw it up, permit it, and provide a bell for
notification in case of a fire. Other than that, details are sketchy until they can
review it. Some AHJ's would go way over-the-top and ask for a separate line, extra hazard
protection, etc.... and another one I could see wanting a special hazard system.
What does everyone else here think about this ? Everyone at the office believes
I am over-thinking it but I believe that over-thinking something is better than
not putting enough thought into something when the alternative could cause more
problems down the road.
Thanks,
Sean
