4. Accessible parking, where parking is being provided.

5. At least one accessible passenger loading zone, when loading zones are provided.

6. At least one accessible route connecting accessible parking and accessible passenger loading zones to an accessible entrance.

Where it is technically infeasible to comply with the new construction standards for any of these requirements for a change of group or occupancy, the above items shall conform to the requirements to the maximum extent technically feasible.

Exception: The accessible features listed in Items 1 through 6 are not required for an accessible route to Type B units.

3411.5 Additions. Provisions for new construction shall apply to additions. An addition that affects the accessibility to, or contains an area of, a primary function shall comply with the requirements in Section 3411.7.

3411.6 Alterations. A building, facility or element that is altered shall comply with the applicable provisions in Chapter 11 of this code, unless technically infeasible. Where compliance with this section is technically infeasible, the alteration shall provide access to the maximum extent technically feasible.

Exceptions:

1. The altered element or space is not required to be on an accessible route, unless required by Section 3411.7.

2. Accessible means of egress required by Chapter 10 are not required to be provided in existing buildings and facilities.

3. The alteration to Type A individually owned dwelling units within a Group R-2 occupancy shall meet the provision for a Type B dwelling unit shall be permitted to meet the provision for a Type B dwelling unit.

4. Type B dwelling or sleeping units required by Section 1107 of this code are not required to be provided in existing buildings and facilities undergoing a change of occupancy in conjunction with alterations where the area of the alteration is 50 percent or less of the aggregate area of the building.

3411.7 Alterations affecting an area containing a primary function. Where an alteration affects the accessibility to, or contains an area of primary function, the route to the primary function area and the amenities serving the area shall be accessible. The accessible route to the primary function area shall include toilet facilities or drinking fountains serving the area of primary function.

Exceptions:

1. The costs of providing the accessible route are not required to exceed 20 percent of the costs of the alterations affecting the area of primary function. The determination of disproportionality and the conditions for applying this exception shall be in accordance with section 3411.7.1.

5. This provision does not apply to altered areas limited to Type B dwelling and sleeping units.

3411.7.1 Disproportionate costs and alternative compliance. Alterations required to be made to provide an accessible path of travel to the altered area will be deemed disproportionate to the overall alteration when the cost exceeds twenty per cent of the cost of the alteration to the primary function area. The determination of disproportionate costs shall be made and applied in accordance with the following:

1. Costs that may be counted as expenditures required to provide an accessible path of travel may include:

1.1 Costs associated with providing an accessible entrance and an accessible route to the altered area, for example, the cost of widening doorways or installing ramps;

1.2 Costs associated with making restrooms accessible, such as installing grab bars, enlarging toilet stalls, insulating pipes, or installing accessible faucet controls;

1.3 Costs associated with providing accessible telephones, such as relocating the telephone to an accessible height, installing amplification devices, or installing a telecommunications device for deaf persons (TDD);

1.4 Costs associated with relocating an inaccessible drinking fountain.

2. Required accessible features in the event of disproportionality.

2.1 When the cost of alterations necessary to make the path travel to the altered area fully accessible is disproportionate to the cost of the overall alteration, the path of travel shall be made accessible to the extent that it can be made accessible without incurring disproportionate costs.

2.2 In choosing which accessible elements to provide, priority should be given to those elements that will provide the greatest access, in the following order:

2.2.1. An accessible entrance;

2.2.2. An accessible route to the altered area

2.2.3. At least one accessible restroom for each sex or a single unisex restroom

2.2.4. Accessible telephones

2.2.5. Accessible drinking fountains

2.2.6. When possible, additional accessible elements such as parking, storage, and alarms

3. Series of smaller alterations. The obligation to provide an accessible path of travel may not be evaded by performing a series of small alterations to the area served by a single path of travel if those alterations could have been performed as a single undertaking.

3.1 If an area containing a primary function has been altered without providing an accessible path of travel to that area, and subsequent alterations of that area, or a different area on the same path of travel, are undertaken within three years of the original alteration, the total cost of alterations to the primary function areas on that path of travel during the preceding three year period shall be considered in determining whether the cost of making that path of travel accessible is disproportionate.

3412.5.3 General safety. Included within the general safety category are the fire safety parameters and the means of egress parameters.

3412.6 Evaluation process. The evaluation process specified herein shall be followed in its entirety to evaluate existing buildings in Groups A, B, E, F, M, R, S, and U. For existing buildings in Group I-2, the evaluation process specified herein shall be followed and applied to each and every individual smoke compartment. Table 3412.7 shall be utilized for tabulating the results of the evaluation. References to other sections of this code indicate that compliance with those sections is required in order to gain credit in the evaluation herein outlined. In applying this section to a building with mixed occupancies, where the separation between the mixed occupancies does not qualify for any category indicated in Section 3412.6.16, the score for each occupancy shall be determined, and the lower score determined for each section of the evaluation process shall apply to the entire building, or to each smoke compartment for Group I-2 occupancies.

Where the separation between mixed occupancies qualifies for any category indicated in Section 3412.6.16, the score for each occupancy shall apply to each portion of the building based on the occupancy of the space.

3412.6.1 Building height. The value for building height shall be the lesser value determined by the formula in Section 3412.6.1.1. Chapter 5 shall be used to determine the allowable height of the building, including allowable increases due to automatic sprinklers as provided for in Section 504.2. Subtract the actual building height in feet from the allowable and divide by 12 ½ feet. Enter the height value and its sign (positive or negative) in Table 3412.7 under Safety Parameter 3412.6.1, Building Height, for fire safety, means of egress and general safety. The maximum score for a building shall be 10.

3412.6.1.1 Height formula. The following formulas shall be used in computing the building height value.

 image: oh/admin/2017/4101_1_34_01_ph_ff_n_ru_20170526_1420_2.png

where:

AH = Allowable height in feet from Section 504.

EBH = Existing building height in feet.

AS = Allowable height in stories from Section 504.

EBS = Existing building height in stories.

CF = 1 if (AH) - (EBH) is positive.

CF = Construction-type factor shown in Table 3412.6.6(2) if (AH) - (EBH) is negative.

Note: Where mixed occupancies are separated and individually evaluated as indicated in Section 3412.6, the values AH, AS, EBH and EBS shall be based on the height of the occupancy being evaluated.

3412.6.2 Building area. The value for building area shall be determined by the formula in Section 3412.6.2.2. Section 506 and the formula in Section 3412.6.2.1 shall be used to determine the allowable area of the building. Subtract the actual building area in square feet from the allowable area and divide by 1,200 square feet. Enter the area value and its sign (positive or negative) in Table 3412.7 under Safety Parameter 3412.6.2, 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 of the fire safety score as listed in Table 3412.8, Mandatory Safety Scores. Group I-2 occupancies shall be scored zero.

3412.6.2.1 Allowable area formula. The following formula shall be used in computing allowable area:


 image: oh/admin/2017/4101_1_34_01_ph_ff_n_ru_20170526_1420_3.png

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.

NS = Tabular allowable area factor in accordance with Table 506.2 or nonsprinklered building (regardless of whether the building is sprinklered).

If = Area factor increase due to frontage as calculated in accordance with Section 506.3.

3412.6.2.2 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.


 image: oh/admin/2017/4101_1_34_01_ph_ff_n_ru_20170526_1420_4.png

where:

i = Value for an individual separated occupancy on a floor.

n = Number of separated occupancies on a floor.

3412.6.3 Comyartmentation. Evaluate the compartments created by fire barriers or horizontal assemblies which comply with Sections 3412.6.3.1 and 3412.6.3.2 and which are exclusive of the wall elements considered under Sections 3412.6.4 and 3412.6.5. Conforming compartments shall be figured as the net area and do not include shafts, chases, stairways, walls or columns.
