Chapter 34 Scopinq Requirements
Compliance Methods
Section 101.5 of Chapter 34 of the MSBC presents the various options available to evaluate the
code requirements applicable to repair, alteration, change of occupancy, addition, or relocation
projects to existing buildings. Users elect one of the available compliance methods to evaluate the
existing building based on the proposed scope of work of the project.The three compliance options
available are as follows:
a. Prescriptive Compliance Method:
Users electing to use this compliance method should follow the requirements outlined in
Section 3 of Chapter 34 to perform the existing building evaluation. This section generally
requires that the alteration comply with new construction requirements and thus is almost
always more stringent than the work area method. Refer to the language below from the
IEBC Commentary.
In addition, using this approach would require multiple complex discussions with local
officials. Although, Howe Engineers anticipates that some issues will be required to be
discussed, it is our opinion that this option leaves too much discretion to the building official
and does not provide enough guidance.
s1 Alterations include renovations, which implies that
something is changed in the structure. For example,
the removal, rearrangement or replacement of parti-
tion walls in an office building is an alteration because,
in part,of the possible impact on the means of egress,
fire resistance or other life safety features of the build-
ing. Conversely, the replacement of damaged trim
pieces on a door frame is considered a repair, not an
alteration. Alterations are to conform to the require-
ments for a new structure. For example, consider the
corridor of an office building that is to be extended 18
feet(5486 mm),as shown in Figure 303.1. The exist-
ing office building has no sprinkler system(and none is
proposed), so the corridor extension walls and doors
are to be fire-resistance rated in accordance with Sec-
tion 1018 of the IBC. This is applicable even if, for
some reason,the walls and doors of the existing corri-
dor system are not fire-resistance-rated construction.
This section also indicates that unaltered portions of a
structure are not required to comply with code provi-
sions for new construction.However,also see Section
310, which requires areas outside of the alteration
area to be revised in order to provide an accessible
route.
b. Work Area Compliance Method:
Users electing to use this compliance method should follow the requirements of Sections
4 through 12 of the MSBC Chapter 34 to perform the existing building evaluation.
4
Howe Engineers, Inc. Chapter 34 Narrative
20 Forsyth Ave.—Performance Compliance Code Report August 11, 2022
c. Performance Compliance Method:
Users electing to use this compliance method should follow the requirements of Section 13
of Chapter 34 of the MSBC to perform the existing building evaluation. This method
generally requires more upgrades than the work area method would require.
Summary &Recommendation of Existing Building Code Options: This report recommends and details
the performance compliance method as this option allows the building to maintain or increase the
current degree of public safety while permitting a change of occupancy without requiring full
compliance to other chapters. For these reasons,the building will be evaluated to the performance
compliance method contained within Chapter 34.

Howe Engineers, Inc. Chapter 34 Narrative
20 Forsyth Ave.—Performance Compliance Code Report August 11, 2022
Performance Compliance Methods (Chapter 14)
The Performance compliance method requires the building to be evaluated using chapter 14 of the
IEBC.The current occupancy consists of Business and Mercantile spaces as previously described.
The building is two(2)stories, approximately 29.5'tall measured to the midpoint of the roof, with a
footprint area of 2154 square feet,and is constructed of type VB construction.The building contains
no corridors, suppression system, smoke control, standpipes, or elevators.The building is split into
compartments by a 2-hr rated ceiling/floor separating the first floor (mercantile) and the second
floor(business).
Applicability (1401.2)
1401.2.2 Partial change in occupancy. Where a portion of the building is changed to a new
occupancy classification and that portion is separated from the remainder of the building with fire
barrier or horizontal assemblies having a fire-resistance rating as required by Table 508.4 (2 hour
separation between R and B/M required)of the International Building Code or Section R317 of the
International Residential Code for the separate occupancies, or with approved compliance
alternatives, the portion changed shall be made to conform to the provisions of this section.
The First floor and second floor are separated by a 2-hour separation and the existing wall(s)
separating the Group B Office space on the Second Floor and the proposed R-2 apartment
will be upgraded to be 2-hour fire resistance rated including new 90-minute self-closing
doors. As such each occupancy will be evaluated separately in this report.
Evaluation (1401.5)
The evaluation shall be comprised of three categories: fire safety, means of egress, and general
safety, as defined in Sections 1401.5.1 through 1401.5.3.
1401.5.1 Fire safety. Included within the fire safety category are the structural fire resistance,
automatic fire detection, fire alarm, automatic sprinkler system and fire suppression system
features of the facility.
1401.5.2 Means of egress. Included within the means of egress category are the configuration,
characteristics, and support features for means of egress in the facility.
1401.5.3 General safety. Included within the general safety category are the fire safety
parameters and the means-of-egress parameters.
This report provides the proposed evaluation in accordance with the three(3)parameters
specified above. Refer to Pages 30-32 for a summary of the analysis for each of the three
(3)occupancies detailed above.

Evaluation Process
Building Height and Number of Stories (1401.6.1)
The value for building height and number of stories shall be the lesser value determined by the
formula in Section 1401.6.1.1. Section 504 of the International Building Code shall be used to
determine the allowable height and number of stories of the building. Subtract the actual building
height from the allowable height and divide by 121/2 feet(3810 mm). Enter the height value and
its sign (positive or negative) in Table 1401.7 under Safety Parameter 1401.6.1, Building Height,
for fire safety, means of egress, and general safety. The maximum score for a building shall be
10.
1401.6.1.1 Height formula. The following formulas shall be used in computing the building height
value.
(Equation 14-1)
(AH) - (EBH)
Height Value Feet = 12 5 x CF
(Equation 14-2)
Height Value,Stories = (AS—EBS) x CF
where:
AH =Allowable height in feet(mm)from Section 504 of the International Building Code.
EBH = Existing building height in feet(mm).
AS=Allowable height in stories from Section 504 of the International Building Code.
EBS= Existing building height in stories.
CF= 1 if(AH)—(EBH) is positive.
CF= Construction-type factor shown in Table 1401.6.6(2) if(AH)—(EBH) is negative.
Note: Where mixed occupancies are separated and individually evaluated as indicated in Section
1401.6,the values AH, AS, EBH and EBS shall be based on the height of the occupancy being
evaluated.

20 Forsyth Ave.—Performance Compliance Code Report August 11,2022
Building Area (1401.6.2)
The value for building area shall be determined by the formula in Section 1401.6.2.2. Section 506
of the International Building Code and the formula in Section 1401.6.2.1 shall be used to
determine the allowable area of the building. Subtract the actual building area from the allowable
area and divide by 1,200 square feet(112 m2). Enter the area value and its sign (positive or
negative) in Table 1401.7 under Safety Parameter 1401.6.2, Building Area,for fire safety, means
of egress and general safety. In determining the area value,the maximum permitted positive
value for area is 50 percent ofthe fire safety score as listed in Table 1401.8, Mandatory Safety
Scores.Group 1-2 occupancies shall be scored zero.
1401.6.2.1 Allowable area formula.The following formula shall be used in computing allowable
area:
(Equation 14-3)
Aa =At+ (NS xIf)
where:
Aa=Allowable building area per story(square feet).
At=Tabular allowable area factor(NS, S1, S13R, or SM value, as applicable) in accordance with
Table 506.2 of the International Building Code.
NS=Tabular allowable area factor in accordance with Table 506.2 of the International Building
Code for a nonsprinklered building (regardless of whether the building is sprinklered).
If= Area factor increase due to frontage as calculated in accordance with Section 506.3 of the
International Building Code.
1401.6.2.2 Area formula.The following formula shall be used in computing the area value.
Determine the area value for each occupancy floor area on a floor-by-floor basis. For each
occupancy, choose the minimum area value of the set of values obtained for the particular
occupancy

Sections 1401.6.3.1 and 1401.6.3.2 and which are exclusive of the wall elements considered
under Sections 1401.6.4 and 1401.6.5. Conforming compartments shall be figured as the net
area and do not include shafts, chases, stairways,walls, or columns. Using Table 1401.6.3,
determine the appropriate compartmentation value(CV) and enter that value into Table 1401.7
under Safety Parameter 1401.6.3, Compartmentation, for fire safety, means of egress, and
general safety.
1401.6.3.1 Wall construction.A wall used to create separate compartments shall be a fire
barrier conforming to Section 707 of the International Building Code with a fire-resistance rating of
not less than 2 hours. Where the building is not divided into more than one compartment,the
compartment size shall be taken as the total floor area on all floors. Where there is more than one
compartment within a story, each compartmented area on such story shall be provided with a
horizontal exit conforming to Section 1026 of the International Building Code. The fire door
serving as the horizontal exit between compartments shall be so installed,fitted, and gasketed
that such fire door will provide a substantial barrier to the passage of smoke.
1401.6.3.2 Floor/ceiling construction.A floor/ceiling assembly used to create compartments
shall conform to Section 711 of the International Building Code and shall have a fire-resistance
rating of not less than 2 hours.

The front stairs are currently partially rated 1-hr and the rear stairs are partially rated except
they are open to the Lunchroom areas. However, Section 1401.6.6 notes that if unenclosed
openings comply with Section 713, then a value of two(2) is assigned. In our opinion,this
section is also referencing Section 712 of the IBC for Vertical openings which does allow
stairs to be open if only connecting two (2) stories and not open to corridors in Group R
occupancies. Further, the stairs must be separated from other occupancies. Thus, if the
Basement door is replaced with a 60-minute door, then the stairs meet the provisions
contained in Section 712.1.9 and achieve a score of 2.

1401.9.1 Mixed occupancies. For mixed occupancies, the following provisions shall apply:
a. Where the separation between mixed occupancies does not qualify for any category
indicated in Section 1401.6.16, the mandatory safety scores for the occupancy with the
lowest general safety score in Table 1401.8 shall be utilized. (See Section 1401.6.)
b. Where the separation between mixed occupancies qualifies for any category indicated in
Section 1401.6.16, the mandatory safety scores for each occupancy shall be placed against
the evaluation scores for the appropriate occupancy.
Summary & Conclusions
The building passes the performance compliance method, provided that it is considered a separated mixed
use occupancy with a 2-hour separation required between the Residential and Business Occupancies at the
Second Floor and the door to the Basement is replaced with a 1-hour rated self-closing door. The existing
separation at the Second Floor will be upgraded to provide a 2-hour rating with 90-minute rated self-closing
doors.
