The provisions of this chapter are intended to maintain or increase the current degree of public safety, health and general welfare in existing buildings while permitting repair, alteration, addition and change of occupancy without requiring full compliance with Chapters 4 through 12, except where compliance with other provisions of this code is specifically required in this chapter.
Alterations, repairs, additions and changes of occupancy to existing structures shall comply with the provisions of this chapter or with one of the methods provided in Section 101.5.
Existing buildings in which there is work involving additions, alterations, or changes of occupancy shall be made to conform to the requirements of this chapter or the provisions of Chapters 4 through 12. The provisions of Sections 1301.2.1 through 1301.2.6 shall apply to existing occupancies that will continue to be, or are proposed to be, in occupancy Groups A, B, E, F, M, R, and S. These provisions shall not apply to buildings with occupancies in Group H or Group I.
Where an existing building is changed to a new occupancy classification and this section is applicable, the provisions of this section for the new occupancy shall be used to determine compliance with this code.
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 wall assemblies having a fire-resistance rating as required by Table 508.3.3 of the Building Codeof New York State or with approved compliance alternatives, the portion changed shall be made to conform to the provisions of this section.

Where a portion of the building is changed to a new occupancy classification and that portion is not separated from the remainder of the building with fire separation assemblies having a fire-resistance rating as required by Table 508.3.3 of the Building Codeof New York State , or with approved compliance alternatives, the provisions of this section which apply to each occupancy shall apply to the entire building. Where there are conflicting provisions, those requirements which secure the greater public safety shall apply to the entire building or structure.
Additions to existing buildings shall comply with the requirements of the Building Code of New York State and this code for new construction. The combined height and area of the existing building and the new addition shall not exceed the height and area allowed by Chapter 5 of the Building Code of New York State . Where a fire wall that complies with Section 705 of the Building Code of New York State is provided between the addition and the existing building, the addition shall be considered a separate building.
An existing building or portion thereof that does not comply with the requirements of this code for new construction shall not be altered or repaired in such a manner that results in the building being less safe or sanitary than such building is currently. If, in the alteration or repair, the current level of safety or sanitation is to be reduced, the portion altered or repaired shall conform to the requirements of Chapters 2 through 12 and Chapters 14 through 33 of the Building Code of New York State .
All portions of the buildings proposed for change of occupancy shall conform to the accessibility provisions of Chapter 11 of the Building Code of New York State .

For repairs, alterations, additions, and changes of occupancy to existing buildings that are evaluated in accordance with this section, compliance with this section shall be accepted by the code enforcement official.
When an unsafe building exists it shall be abated in accordance with 19 NYCRR Part 1203.3(f).
Buildings that are evaluated in accordance with this section shall comply with the Fire Codeof New York State and Property Maintenance Code of New York State.
In flood hazard areas, buildings that are evaluated in accordance with this section shall comply with Section 1612 of the Building Codeof New York State if the work covered by this section constitutes substantial improvement.
For proposed work covered by this chapter, the building owner shall cause the existing building to be investigated and evaluated in accordance with the provisions of Sections 1301.4 through 1301.9.
The owner shall have a structural analysis of the existing building made to determine adequacy of structural systems for the proposed alteration, addition, or change of occupancy. The existing building shall be capable of supporting the minimum load requirements of Chapter 16 of the Building Code of New York State.
The results of the investigation and evaluation as required in Section 1301.4, along with proposed compliance alternatives, shall be submitted to the code enforcement official.
The code enforcement official shall verify whether the existing building, with the proposed addition, alteration, or change of occupancy, complies with the provisions of this section in accordance with the evaluation process in Sections 1301.5 through 1301.9.
The evaluation shall be comprised of three categories: fire safety, means of egress, and general safety, as described in Sections 1301.5.1 through 1301.5.3.
Included within the fire safety category are the structural fire resistance, automatic fire detection, fire alarm, and fire-suppression system features of the facility.
Included within the means of egress category are the configuration, characteristics, and support features for means of egress in the facility.
Included within the general safety category are the fire safety parameters and the means-of-egress parameters.
The evaluation process specified herein shall be followed in its entirety to evaluate existing buildings. Table 1301.7 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 1301.6.16, 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.

Where the separation between the mixed occupancies qualifies for any category indicated in Section 1301.6.16, the score for each occupancy shall apply to each portion of the building based on the occupancy of the space.
The value for building height shall be the lesser value determined by the formula in Section 1301.6.1.1. Chapter 5 of the Building Code of New York State , including allowable increases due to automatic sprinklers as provided for in Section 504.2, shall be used to determine the allowable height of the building. Subtract the actual building height from the allowable height and divide by 12 1 / 2 feet (3810 mm). Enter the height value and its sign (positive or negative) in Table 1301.7 under Safety Parameter 1301.6.1, Building Height, for fire safety, means of egress, and general safety. The maximum score for a building shall be 10.
The following formulas shall be used in computing the building height value.

Note:
Where mixed occupancies are separated and individually evaluated as indicated in Section 1301.6, the values AH, AS, EBH, and EBS shall be based on the height of the fire area of the occupancy being evaluated.
The value for building area shall be determined by the formula in Section 1301.6.2.2. Section 503 of the Building Code of New York State and the formula in Section 1301.6.2.1 shall be used to determine the allowable area of the building. The allowable area shall be the lesser value calculated by Equations 13-2 and 13-3. This shall include any allowable increases due to open perimeter and automatic sprinklers as provided for in Section 506 of the Building Code of New York State . 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 1301.7 under Safety Parameter 1301.6.2, 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 1301.8, Mandatory Safety Scores.
