1944
Church of Jesus Christ of Latter-day Saints. The design allows for the
DRINKING FOUNTAINS
construction of phased additions to the building to accommodate the
1:200 = 4
current and future needs of the congregation without major disruption of
WOMEN
618/75=9
service. The initial phase may vary from approximately 2,400 square feet
PROVIDED
up to a possible full build -out of about 20,000 square feet with various sizes
N_:' _ ,
in between. Each phase of construction has similar code requirements and
4
are therefore summarized herein as a complete building with notations for
WOMEN 9
exceptions permissible in the smaller building phases.

N
construction (V -B).
Chapter 5 - General
Building Heights & Areas
Table 503
A-3 Occupancy (Type V -B construction) basic allowable square footage=
