Mike,
Don't forget that unless the home is made out of concrete and steel,
you're most likely going to have to protect the attic space, should
there be one, and that can result in a much larger remote area, limited
sprinkler spacing, and higher starting pressures (see table
8.6.2.2.1a). Also, if you're looking at flowing 90 gallons (900 square
feet x 0.10 gpm) through a 1" water meter you'd be well advised to think
again. Also, remember your minimum water supply duration jumps from 10
minutes (13D), to 60 minutes in NFPA-13.
Lot's to discuss there, and if you'd like to contact me on the phone
I'll be glad to talk over some of the other issues.

An AHJ wants a 13 system in a 7,300 sqft house because of it's remoteness from
the street. Is the best I can do is calculate 900 sqft because of it being
light hazard with ceilings less that 12' high? Or can I reduce the area more
some how? Please help.
Mike
