Note comment is to million sf, not small building being discussed.
Have you had discussion with architect. They should be familiar with any
site specific items done as trade offs.
It is rather uncommon for these to be included in bid requests.

We have done a few million plus sqft. one story buildings (distribution
center). The biggest issue usually is the 250' verses 400' exit travel and
smoke vents with ESFR's. No standpipes required.

Looks like 905.4 remains relatively unchanged in 2012, but there is zero
reference as to when to apply it.
What about a million sq.ft. single story building?

Interesting interpretation.
FYI, the 2012 edition removed "and in the locations indicated in
Section905.4, 905.5, and 905.6".

2009 IFC 905.3 read strictly does not tie standpipe hose connections to
height. It states ..."where required by sections 905.3.1 through 905.3.7
and in the locations indicated in Sections 905.4, 905.5, and 905.6."
Section 905.4 needs to be applied regardless of 905.3.1 because of the "and"
after 905.3.1 in section 905.3. (wow that's wordy).
Personally I do not believe the intent is to provide hose connections in any
building that has more than one floor or where the fire truck is more than
200 feet from any point in the building, but I see how it could be read that
way. I always thought 905.4 was intended for very expansive buildings such
as those seen out west. Maybe this section should be tied to a square
footage.

Per IBC:
905.3.1 Class III standpipe systems shall be installed throughout buildings
where the floor level of the highest story is located more than 30 feet
(9144 mm) above the lowest level of fire department vehicle access, or where
the floor level of the lowest story is located more than 30 feet (9144 mm)
below the highest level of fire department vehicle access.
STORY. That portion of a building included between the upper surface of a
floor and the upper surface of the floor or roof next above (also see
"Basement," "Building height," "Grade plane" and "Mezzanine"). It is
measured as the vertical distance from top to top of two successive tiers of
beams or finished floor surfaces and, for the topmost story, from the top of
the floor finish to the top of the ceiling joists or, where there is not a
ceiling, to the top of the roof rafters.
MEZZANINE. An intermediate level or levels between the floor and ceiling of
any story and in accordance with Section 505.
505.2 Mezzanines.
A mezzanine or mezzanines in compliance with Section 505.2 shall be
considered a portion of the story below.
A 32' high mezzanine doesn't constitute standpipes.

A small 2 story area the rest is all one story. There is a running track on
a mezzanine that circles the gym that is at 32 ft. high but it is open to
the gym. This is an addition to a building that is sprinklered but without
standpipes. The new addition meets all the exiting and egress requirements
so that is not an issue.

How many stories is the building, and on what floor is this condition?

This from a Fire Marshal for a large University in AZ. We were having
trouble locating hose valves in the one story area of the building.
There are only two stairs in the building and they are more than 200 ft.
from parts of the gymnasium. We reviewed the code and offered a credit to
delete the standpipe system because we didn't think it was required.
This the response from the FM. He wants all interior points to be with
150 feet from where they park a fire truck.
"If you send a too scale plan from where fire trucks will be at all points
of entry to the building and can show that nothing is more than 150' I will
entertain the suggestion of no standpipes. I have seen everything that
****** has been shown and it is not represented well.
This includes the existing building since the existing building had adequate
coverage and did not need a standpipe before the add-on. Now that there is
an add-on where there is no access at the center point it affects both the
new and old and we need assurance with a too scale drawing from fire truck
to all areas of all floors. Discussing it does not solve anything until you
can also prove it on paper too scale "as the hose lays and not the crow
flys."
I have difficulty finding a way to talk to someone like this.
