S-2 Occupancy
Indianapolis, IN
Chapter 34 Analysis
1. The project involves the conversion of a portion of the 1
st floor of an existing building into a church and the existing
warehouse will be used to store vehicles. The remainder of the building will remain as offices. The church and office
space will be separated from the warehouse/garage by a 2-hour fire barrier. The building will be classified as an
A-3/B/S-2 Occupancy. The existing building is 2-stories and Type IIIB Construction. The 1st floor is 13,846 sq.ft. and
the 2nd floor is 2,527 sq.ft.
2. The proposed conversion of the building is classified as a “change of occupancy” per Rule 4, Section 11(b), GAR.
3. Rule 4, Section 11(b), GAR, permits existing structures undergoing a change in occupancy to comply with either;
• The rules for new construction for the proposed new use, or
• Sec. 3412, IBC, “Compliance Alternatives”
4. Due to issues involved with bringing the existing building into compliance with all current rules of the Commission, Sec.
3412, IBC is used as the benchmark method of evaluating existing building compliance for the proposed use of the
building.
5. The proposed strategy will permit the conversion of the building for the proposed use based upon conditions of the
building as indicated in the attached score sheets.
• The church and office space will be separated from the warehouse/garage by a 2-hour fire barrier, with 90-minute
rated openings.
• A smoke detection system is provided in the HVAC where required by the IMC.
• Exit signs and emergency lighting will be provided in the garage.

Building Score Sheet Analysis
3412.6.1 The S-2 fire area is 1-story in height. The building is permitted to be 4 stories and 55' in height based
upon an S-2 Occupancy of Type IIIB Construction. Height Value for feet: (55 - 25)/12.5 = 2.4
Height Value for number of stories: 4 - 1 = 3 (lessor value for stories is used in the score sheet)
3412.6.2 Allowable area for Type IIIB Construction for separated mixed uses of an A-3/B & S-2 Occupancy:
Allowable area: A-3/B = Tabular (9,500 sf) + Frontage (7,125 sf) = 16,625 sf
Allowable area: S-2 = Tabular (26,000 sf) + Frontage (19,500 sf) = 45,500 sf
Value = 45,500/1,200 [1- (6,677/16,625 + 7,169/45,500)] = 16.7*
*Maximum score is 50% the fire safety mandatory score = 11.5
3412.6.3 The fire area is 7,169 square feet.
Compartmentation value = 10 + (7,169 - 7,500)[(15-10)/(5,000-7,500)] = 10.7
