19 NYCRR Parts 1228, 1264, and 1265

This rule making would amend 19 NYCRR Parts 1228, 1264, and 1265 to reference the 2017 Uniform Code Supplement, as opposed to the 2016 Uniform Code Supplement.

At its meeting held July 13, 2017, the Code Council voted to adopt a rule to amend the Uniform Code and the Code Council did not find that an earlier effective was necessary to protect health, safety, and security or that the change to the Uniform Code would not impose any additional compliance requirements on any person. Therefore, the rule and the changes to the Uniform Code made by the rule will become effective ninety days after the date on which notice of such change has been published in the State Register.

Pursuant to Executive Law § 377(1), Secretary of State Rosanna Rosado reviewed the amendment of the Uniform Code to be implemented by this rule, found that such amendment effectuates the purposes of Article 18 of the Executive Law, and therefore approved said amendment.

The Department of State has determined that the changes made to the last published rule are non-substantive and do not necessitate a revision of the original Regulatory Impact Statement published in the Notice of Proposed Rule Making.

Those changes made to the rule are summarized as follows:

Parts 1220 through 1228 of Title 19 NYCRR were changed to update the date that the 2017 Supplement was published from March to July. Changes were made throughout the 2017 Uniform Code Supplement to clarify certain code language and to delete duplicative code language. The majority of the changes were to Chapter 11 of the 2015 International Residential Code (IRC).

The legally binding provisions of the State Energy Conservation Construction Code (Energy Code) are as set forth in 19 NYCRR Part 1240, and consist, primarily, of the 2015 International Energy Conservation Code (IECC) and ASHRAE 90.1-203, as amended by the 2016 Supplement to the New York State Energy Conservation Construction Code (Revised August 2016) (ECS). Chapter 11 of the 2015 IRC, as amended by the 2017 Uniform Code Supplement, is intended to be a restatement of the provisions of the Energy Code applicable to residential buildings. However, in the event of a conflict between provisions of Part 1240 and the provisions in Chapter 11, the provisions of Part 1240 will control. To address any discrepancies, the 2017 Uniform Code Supplement has been revised to align the Chapter 11 provisions with the corresponding provisions of the IECC/ECS.

The Department of State has determined that the changes made to the last published rule are non-substantive and do not necessitate a revision of the original Regulatory Flexibility Analysis for Small Businesses and Local Governments published in the Notice of Proposed Rule Making.

The changes made to the previously published rule text provide clarification as to the application of the proposed text and do not alter or increase any effect of the rule upon small businesses or local governments.

This rule making would amend the current version of the Uniform Fire Prevention and Building Code (Uniform Code) by replacing the 2016 Uniform Code Supplement with a new publication entitled the 2017 Uniform Code Supplement. The proposed new text of the Uniform Code is based upon the new modifications to the 2015 editions of model codes developed by the International Code Council, Inc. (ICC), as set forth in the 2017 Uniform Code Supplement. The Uniform Code is applicable in all areas of the State with the exception of the City of New York.

The Department of State has determined that the changes made to the last published rule are non-substantive and do not necessitate a revision of the original Rural Area Flexibility Analysis published in the Notice of Proposed Rule Making.

The changes made to the previously published rule text provide clarification as to the application of the proposed text and do not alter or increase any effect of the rule upon rural areas in New York State.

The rule would amend the current version of the Uniform Fire Prevention and Building Code (Uniform Code), by replacing the 2016 Uniform Code Supplement with a new publication entitled the 2017 Uniform Code Supplement. The proposed new text of the Uniform Code is based upon the new modifications to the 2015 editions of model codes developed by the International Code Council, Inc. (ICC), as set forth in the 2017 Uniform Code Supplement. The Uniform Code is applicable in all areas of the State with the exception of the City of New York. Therefore, adoption of this rule making will apply to all rural areas of the State.

The following changes were made to sections in the Revised 2016 Energy Code Supplement:

Changes in Part 1

In Item 1.7, the terms “commercial building,” “historic building,” and “2015 International Property Maintenance Code (as amended)” were added to the list of definitions added or amended by section 1.7.

In Item 1.8, which amends section C302.2 of the 2015 IECC Commercial Provisions, a note was added to clarify that Item 1.8 does not delete or amend section C303.2.1 of the 2015 IECC Commercial Provisions.

In Item 1.9, which amends section C401.2 of the 2015 IECC Commercial Provisions, a note was added to clarify that Item 1.9 does not delete or amend section C401.2.1 of the 2015 IECC Commercial Provisions.

Item 1.10 was revised to correct the numbering of the new section added by section 1.10 (“C402.2.6” was changed to “C402.6.7”). In addition, a note was added to clarify that Item 1.10 does not delete or amend sections C402.2.1, C402.2.3, C402.2.4, C402.2.5 or C402.2.6 of the 2015 IECC Commercial Provisions.

In Item 1.12, the caption was revised to correct the reference to the section in the 2015 IECC Commercial Provisions amended by section 1.13 (“C402.4.1” was changed to “C402.4.2”).

In Item 1.13, the caption was revised and word “stove” was changed to “stoves.”

In Item 1.18, the description of the publication known as “ASHRAE Appendix G Excerpt – 2015” was changed to reflect more accurately the manner in which that publication is referenced in the 2015 IECC Commercial Provisions (as amended).

In Item 1.19, the word “paragraphs” was changed to “Items.”

Changes in Part 2

Item 2.2, which amends section 4.2.1.1 of ASHRAE 90.1-2013, was revised to clarify that the new item “c” added by Item 2.2 is one of three paths permitted by section 4.2.1.1 of ASHRAE 90.1-2013; to correct the formula for “PCIt” (the second equal sign was changed to a plus sign); and to add a new description of how “regulated energy cost” and “unregulated energy cost” are to be calculated.

Item 2.3 was revised to correct the reference to the section in ASHRAE 90.1-2013 that is amended by section 2.3 (“4.1.2.3” was changed to “4.2.1.3” in two places).

Item 2.5 was revised to correct the reference to the section in ASHRAE 90.1-2013 that is amended by Item 2.5 (“8.41” was changed to “8.4.1” in two places), to add the exception for circuits used for emergency services (the exception was inadvertently omitted from the Original 2016 Energy Code Supplement), and to clarify the fact that sections 8.4.1.1 and 8.4.1.2 of ASHRAE 90.1-2013 are not included in section 8.4.1 of ASHRAE 90.1-203 as amended by Item 2.5 of the Revised 2016 Energy Code Supplement.

In Item 2.7, the word “paragraphs” was changed to “Items.”

Changes in Part 3

Item 3.3 amends and restates Chapter 1 of the 2015 IECC Residential Provisions. In the portion of Item 3.3 that amends and restates section R101.1 of the 2015 IECC Residential Provisions, a reference in the final line to the “2015 IECC” was corrected to be a reference to the “2016 Energy Code Supplement.”

In Item 3.5, the terms “historic building” and “2015 International Property Maintenance Code (as amended)” were added to the list of definitions added or amended by Item 3.5, and the definition of “residential building” was corrected by changing the reference to the “2010 Building Code of New York State” to a reference to the “2015 International Building Code (as amended).”

In Item 3.6, which amends section R303.2 of the 2015 IECC Residential Provisions, a note was added to clarify that Item 3.6 does not delete or amend section R303.2.1 of the 2015 IECC Residential Provisions.

Item 3.7 of the Revised 2016 Energy Code Supplement amends sections R402.1, R402.1.1, and R402.1.2 of the 2015 IECC Residential Provisions. The amendments of sections R402.1 and R402.1.1 are the same as the amendments made in items 7 and 8 of Part 3 of the Original 2016 Energy Code Supplement. The amendment of section R402.1.2 is new. Amended section R402.1.2 provides that buildings in climate zone 6 may comply with either of the two rows for climate zone 6 in Table R402.1.2. In addition, a note was added to Item 3.7 to clarify that Item 3.7 does not delete or amend sections R402.1.3, R402.1.4 or R402.1.5 of the 2015 IECC Residential Provisions.

Item 3.8 adds a new row for Climate Zone 6 to Table R402.1.2 of the 2016 IECC Residential Provisions. The new row provides a new option for Climate Zone 6, which allows the use of R-25 cavity-only insulation in wood frame walls, provided that (1) the fenestration U-factor is reduced to 0.28 and (2) the R-value of the insulation in the basement wall and in the crawl space wall is increased from 15/19 to 15/20. Based on recently developed studies and information relating to the Vermont Residential Building Energy Standards (RBES), the Department of State now believes that this additional option for buildings in climate zone 6 meets the REScheck compliance path and does not constitute a substantial change to the Original Rule.

In Item 3.10, a note was added to refer to Item 3.14 for a more complete description of the effect of Items 3.10 through 3.14 on Section R402.4 (including sections R402.4.1, R402.4.1.1, R402.4.1.2, R402.4.1.3, R402.4.2, R402.4.3, R402.4.4, R402.4.5, and R402.4.6) of the 2015 IECC Residential Provisions.

In Item 3.14, references to section numbers were corrected (“C402.4” was changed to “R402.4” and “C402.4.6” was changed to “R402.4.6”). In addition, a note was added to clarify that sections R402.4.1, R402.4.1.1, R402.4.3, R402.4.4, and R402.4.5 of the 2015 IECC Residential Provisions were not deleted or amended by Items 3.10 through 3.14 of the Revised 2016 Energy Code Supplement, and to summarize the effect of Items 3.10 through 3.14 on Section R402.4 (including sections R402.4.1, R402.4.1.1, R402.4.1.2, R402.4.1.3, R402.4.2, R402.4.3, R402.4.4, R402.4.5, and R402.4.6) of the 2015 IECC Residential Provisions.

In Item 3.15, which amends section R403.3.2 of the 2015 IECC Residential Provisions, a note was added to clarify that Item 3.15 does not delete or amend section R403.3.2.1 of the 2015 IECC Residential Provisions.

In Item 3.16, which amends section R403.6 of the 2015 IECC Residential Provisions, a note was added to clarify that section 3.16 does not delete or amend Item R403.6.1 of the 2015 IECC Residential Provisions.

Item 3.20 was revised to clarify its meaning (“Compliance with this section requires that the mandatory provisions identified in Sections R401.2 and R403.5.3 be met” was changed to “Compliance with this section requires that (1) the provisions in Sections R401 through R404 labeled as ‘mandatory’ and (2) the provisions of Section R403.5.3 be met”).

The Department of State has determined that the changes made to the last published rule are non-substantive and do not necessitate a revision of the original Job Impact Statement published in the Notice of Proposed Rule Making.

The changes made to the previously published rule text provide clarification as to the application of the proposed text and will not have a substantial adverse impact on jobs and employment opportunities in New York State.

The rule would amend the current version of the Uniform Fire Prevention and Building Code (Uniform Code). The current version of the Uniform Code (19 NYCRR Parts 1220 through 1227) became fully effective on October 3, 2016. It is based upon the 2015 editions of model codes developed by the International Code Council (ICC), with some New York modifications as set forth in the 2016 Uniform Code Supplement. If adopted, this rule would replace the 2016 Uniform Code Supplement with a new publication entitled the 2017 Uniform Code Supplement. The 2017 Supplement is intended to make corrections to the 2016 Supplement and address topics specific to New York.

The ICC model codes incorporate the most current technology in the areas of building construction and fire prevention. The ICC codes are updated on a three-year cycle to stay current with industry practice and technical and life-safety evolution. The Department of State concludes that this update, which is based upon the current edition of the ICC model codes with some New York modifications as set forth in the 2017 Uniform Code Supplement, will continue to provide a greater incentive to construction of new buildings and rehabilitation of existing buildings. Therefore, this rule making will not have a substantial adverse impact on jobs and employment opportunities within New York.

As a rule that requires a RFA, RAFA or JIS, this rule will be initially reviewed in the calendar year 2020, which is no later than the 3rd year after the year in which this rule is being adopted.

Comments were received requesting deletion of certain New York State (NYS)-specific amendments to the International Code Council’s (ICC) model code requirements in favor of adopting the model codes without amendment, including but not limited to: assistive listening systems, the definition of the terms “dwelling unit” and “story above grade plane”, water reducing plumbing fixtures, flame safeguard devices; IRC Sections R303.10 (required heating), R306.1 (toilet facilities), R306.2 (kitchen), R322.1.4 (establishing the design flood elevation), R322.1.4.1 (determination of design flood elevations, R322.1.7 (protection of water supply and sanitary sewage systems), R324.3 (Photovoltaic systems), R324 (Solar energy systems), E3609.7 (bonding other metal piping), AJ604.3 (Automatic sprinkler systems), and Table P2903.2 (Maximum flow rates and consumption for plumbing fixtures and fixture fittings); IPC Table 604.4 (Maximum flow rates and consumption for plumbing fixtures and fixture fittings); IBC Sections 1108.2.7 (Assistive listening systems) and 716.6.7.1 (Where 3/4-hour fire protection window assemblies permitted); IFGC Sections 404.7 (Protection against physical damage), 404.7.1 (Shield plates), and 602.2 (Flame safeguard device); modifications to IFC Sections 605.11 (Solar photovoltaic power systems), and 5306.2 (Interior supply location); IPMC Section 302.8 (Motor vehicles); and IEBC Section 805.3.1.1 (Single-exit buildings). Because these requested modifications were either substantive or would not comply with NYS statutory requirements or a directive of the State Fire Prevention and Building Code Council (Code Council), these changes were not made at this time.

Comments were received requesting deletion of the following NYS-specific code requirements that are in addition to the ICC model code requirements, including but not limited to: 2017 Uniform Code Supplement Chapter 1 Sections 102.2.1, 107, 108, and 109; IBC Sections 427 (health care facilities), 907.2.1 (Group A), 1107.2.1 (Type B unit doors), and 1107.2.2 (Type B unit toilet and bathing facilities), IBC Appendix N; IRC Sections R314.9 (Portable smoke alarms in lodging houses), R314.8 (Lodging house evacuation notices), and M1401 (General); IMC Section 901 (General); IFGC Section 631.1.1 (Other standards); IFC Sections 403.2.5 (Education Law requirements for Groups A college and university buildings), 403.4.1 (Education Law requirements for Group B college and university buildings), 403.12.2 (Public safety plans for gatherings), 603.10 (Solid fuel-burning heating appliances, chimneys and flues), 806.1.1 (Restricted occupancies), 1031.10 (Capacity of means of egress), 1031.11 (Posting of occupant load), 1031.12 (Overcrowding), and Table 901.6.1 (Fire Protection System Maintenance Standards); IPMC Sections 302.3.1 (Off-street parking lots), 304.2.1 (Lead-based paint), 305.3.1 (Lead-based paint), and 608 (assistive listening systems); and IEBC Section 202 (definition of the term “international symbol of accessibility”). Because these requested modifications were either substantive or would not comply with NYS statutory requirements or a directive of the Code Council, these changes were not made at this time.

Comments were received requesting modifications to certain provisions of the Uniform Code, including but not limited to: IRC Sections 324.7.3 (Ground access areas), R324.7 (Access and pathways), R324.7.2 (Roof access points), R324.7.4 (Single ridge roofs), R324.7.6 (Roofs with valleys), and R324.7.7 (Allowance for smoke ventilation operations); IRC and IFC rooftop solar provisions to address residential flat roofs, clarifications of vertical ventilation techniques and alternative ventilation methods (applicable to the IRC and IFC rooftop solar provisions); automatic fire sprinkler system in townhouses; IPC Section 1002.6 (Building traps) and 2015 IRC Section P3201.4 (Building traps); request for adoption of Article 555 from the updated 2017 National Electrical Code; IFC Section 605.11.1.3 (Other than Group R-3 Buildings); IRC Table P2903.2 (maximum flow rates and consumption for plumbing fixtures and fixture fittings); and IPC Table 604.4 (maximum flow rates and consumption for plumbing fixtures and fixture fittings). Because these requested modifications were either substantive or would not comply with NYS statutory requirements or a directive of the Code Council, these changes were not made.

Comments were received pointing out potential code discrepancies and the possible need for corrections to the Uniform Code, including but not limited to: carbon monoxide alarm requirements found in IRC Section AJ504.3, IRC Section AJ604.2, and IFC Section 915.2; missing Referenced Standards TPI, UL, ULC, USC, and WDMA; a separate electric meter requirement for individual dwelling units (IRC dwellings) similar to what had been required in the 2010 RCNYS; factory vs. site performed blower door tests for factory manufactured homes; IRC Section R313 vs. garage separation to account for sprinklers not being required (similar to what had been done in the 2010 RCNYS); IRC Section 304.1 (Minimum area) vs. IPMC Section 404.4.1 (Room area); IRC Section R305.1 (Minimum height) vs. IPMC Section 404.3 (Minimum ceiling heights); IRC definition of freeboard; and illuminated means of egress similar to Section 1029.8 of the FCNYS. These comments did not require substantive changes to the Uniform Code.

Duplicative code language was deleted and certain code language was clarified in such a manner as to require Items to be renumbered in certain chapters of the 2017 Supplement.

Description of Changes Made in the Rule

This rule will amend the current versions of Parts 1220 through 1228, 1264, and 1265 of Title 19 of the Official Compilation of Codes, Rules and Regulations of the State of New York (NYCRR) by replacing references to the 2016 Uniform Code Supplement with the new publication entitled 2017 Uniform Code Supplement (2017 Supplement).

Changes to the 2017 Supplement

General Changes

Formatting changes such as margins, spacing, and indents were made throughout the 2017 Supplement. For the sake of clarity, whenever a change is described herein to an Item number in the 2017 Supplement, such change shall refer to the original numbering convention, and not the numbering convention resulting from the change.

Changes to the Table of Contents

The table of contents has been changed to coordinate with the amendments to Chapters 2, 3, 7, and 10.

Changes to Chapter 2

Item 2.2: The following terms were added to coordinate with the amendments made to IRC Chapter 11: air-impermeable insulation”, “building thermal envelope”, “conditioned space”, and “ERI reference design.

Item 2.5: Item 2.5 has been deleted as it can never be applied, since an electrical power supply is required by Exceptions 1 and 2.

Item 2.6: Item 2.6 has been deleted as it can never be applied, since an electrical power supply is required by the Exception.

Item 2.25: Exception 1 to R324.7 was separated into two exceptions to provide clarity. Because R324.7 and R324.7.7 share similar exceptions, a similar modification was made to R324.7.7. R324.7.2, item 5 has been clarified to state that roof access points shall be located where the accompanying ground access area does not conflict with ground obstructions. Section R324.7.3 has been amended to delete the word “directly” and insertion of the phrase “so as to facilitate roof access” and clarifies where ground access areas shall be located.

Item 2.28: The legally binding provisions of the Energy Code are as set forth in 19 NYCRR Part 1240, and consist, primarily, of the 2015 International Energy Conservation Code (IECC) and ASHRAE 90.1-203, as amended by the 2016 Supplement to the New York State Energy Conservation Construction Code (Revised August 2016) (ECS). Chapter 11 of the 2015 IRC, as amended by the 2017 Uniform Code Supplement, is intended to be a restatement of the provisions of the Energy Code applicable to residential buildings. However, in the event of a conflict between provisions of Part 1240 and the provisions in Chapter 11, the provisions of Part 1240 will control. To address any discrepancies, the 2017 Uniform Code Supplement has been revised to align the Chapter 11 provisions with the corresponding provisions of the IECC/ECS as described herein. These modifications include:

1. New exceptions 2 and 3 to IRC Section N1101.1;

Changes to Chapter 3

Item 3.3: Item 3.3 has been deleted. It was placed in the 2016 Supplement in response to an errata report from the ICC which made a correction to the first printing of the 2015 IBC. The third printing of the IBC that was adopted incorporated this correction. The contents of Item 3.3 are duplicative of what appears in the adopted IBC.

Changes to Chapter 7

New Item 7.9: A new Item 7.9, which amends Section 503.1 of the IFC, was added to the Supplement to clarify that Appendix D was adopted and made part of the IFC.

Item 7.13: Item 7.13, Section 511.2.6, did not have a section heading and was subsequently titled “Driveways serving more than four buildings”.

Item 7.15: Section 605.11.1 is substantially similar to IRC Section R324.7. Consequently, the clarification that was made to IRC Section R324.7, which separated Exception 1 into two exceptions, has been made for Section 605.11.1. Section 605.11.1.1 is substantially similar to IRC Section R324.7.2. Therefore, the clarification made to IRC Section R324.7.2 has also been made to 605.11.1.1. This clarification states that roof access points shall be located where the accompanying ground access area does not conflict with ground obstructions. Section 605.11.1.2.2 is substantially similar to IRC Section R324.7.3. Likewise, the clarification made to IRC Section R324.7.3 has also been made to Section 605.11.1.2.2. This amendment deletes the word “directly” and inserts the phrase “so as to facilitate roof access”, clarifying where ground access areas shall be located. Finally, Section 605.11.1.2.6 is substantially similar to IRC Section R324.7.7. Therefore, the clarification made to IRC Section R324.7.7 has also been made to Section 605.11.1.2.6, which separated Exception 1 into two exceptions.

Item 7.16: The reference to “soda ash” extinguisher has been deleted from Section 806.1.1 so as to correctly reference fire extinguishers in conformance with NFPA 10. A footnote has been added to further clarify the exception.

Item 7.28: The reference to “Part” 1203.3(g) has been changed to “Section”. The reference to subdivision (h) has been corrected to reference Section 5610.8.

Changes to Chapter 9

Item 9.3: The missing reference to footnote “a” was inserted into Table 805.3.1.1(1).
