Thanks for the response Thom and the mention of those little add-ons I may
encounter.

No limit on height, and no limit on area, in 13D, however some jurisdictions
require a 3 or 4 head design over x sqft total area. And some require 4
heads @0.1 if slope exceeds 8/12. It's just jurisdiction created.
We currently have a 13D duplex with the top floor 45'-0" above the lowest

See if this is what you're after:
NFPA-13, 2007 edition, 8.7.3.1.7 states:
Where sidewall standard spray sprinklers are installed to protect areas
below overhead doors
within ordinary hazard occupancy spaces or rooms, protection area and
maximum sprinkler
spacing for light hazard as specified
Quick question:
When you use a single horizontal sidewall sprinkler to cover the area under
an open overhead door would you still use the spacing for whatever occupancy
is below? If, let's say, this is an Ord Group II hazard this would limit a
sidewall sprinkler to 10'x10' - and if I have a 10 ft.
Yeah, I went there first and found that 13D was not modified so that just
throws me back to interpreting NFPA. They have; however, modified 13R to
spell out Day Care specifically so that limits the floors. But I need to not
confine myself to just Georgia at this time.
Thanks for the suggestion.

Excellent. Now I can move on.
A big thanks to Steven, Richard and George for your input.

I believe a day care with more than 12 "clients" requires a 13R system.

Right. And I have run into locales where a #13D is acceptable for a day
care, egress is the only concern. In the first that comes to mind, we
sprinklered portions of a church used as daycare, along with the egress
corridors, with #13D and a 2-head flow, #13D tank and pump.

Sorry, I mis-wrote when I wrote "This suggests to me that it can have more
floors if the system is supplied by a tank as the sole supply." I meant to
write "This suggests to me that it can have more floors if the sole supply
is NOT a tank".
Anyway, I would think that there would be some floor limit
Double check the occupancy classification. If it's still considered an
R3 (single family), then 13D should be ok. If a different occupancy
classification such as an "I" then it's no longer considered a single
family but a commercial hence a full 13 system may be required. The

Re-read the supply section; you can reduce the duration from 10 to 7 minutes

the standard.

I need to add that the building is used as a daycare. In my state the entire
building can be 13D and designed as one dwelling unit.

I need help finding something again. Becoming a habit lately. How many
stories can a 13D building have? The only reference to this is in the water
supply section under tanks as the sole supply where it states that one of
the requirements is the building cannot be more than one story. This

Do you mean flexible hoses running to the sprinkler heads?
If so, I can't imagine the cost dif between the original innovator
version and the cheapest UL-Listed Only version you could find would be a
factor of x2, not x4.
If not, either the market over your way is completely different distributi
