Required? Technically no. It would be in NFPA 13D Chapter 11 if it was in the code, and I'm not seeing it in the 2016 edition.

Best practice? Yes. Easily. Better for inspections, maintenance, and testing if they know what the system was designed to. And it's not like this breaks the bank or requires a lot of additional labor, it's copying data from the plan.

But no, I can't see an actual requirement for a hydraulic placard in the corresponding section of NFPA 13D. I hope I'm proven wrong on this.

Considering 13D allows for both a "General Pipe Size Method" (12 step) and a "Prescriptive Pipe Sizing Method" (8 step) in addition to the option of a standard Hydraulic Calculation procedure, other than some basic info for K-factor & max spacing of a sprinkler/max flow rate, getting that deep into the results in unnecessary.

Many times it's just sharpie'd into the backside of the access panel at the riser in my area, sometimes there are stickers but only giving the basic info.

Warning signs for antifreeze placards and combined systems are the only things I can think of.

Technically NFPA 13D systems do not require yearly inspections after the initial installation. It seems as though 13D systems are left to the owner to upkeep and call if there is any problems that occur. If the 13D system is installed in a care facility I believe then they are required to have yearly inspections based on the states requirements.

Typically no. We don't include hydraulic placards on our 13D projects

Now and then a house is remodelled, added to, so the system needs be updated. I review plans for some AHJ's,
and we have added a few items in our Adopting Ordinances for 13D.
One is that the valve that controls the sprinklers is before the domestic split off, and is Indicating.
Another is that they do supply a hydraulic placard.

Might make sense to require plans for ALL systems be left at job sites. Where there is a riser room, could leave it in a plastic cover?

Required - no. But it would be helpful knowing the maximum spacing permitted/design criteria for future renovation projects within the home.
