PROPOSED RULES

BUILDING CODE COUNCIL

[Filed August 6, 1997, 10:28 a.m.]

Original Notice.

Preproposal statement of inquiry was filed as WSR 97-05-065.

Title of Rule: Repeal of chapter 51-30 WAC, adoption and amendment of the 1994 Edition of the Uniform Building Code; and adoption of chapter 51-40 WAC, adoption and amendment of the 1997 Edition of the Uniform Building Code.

Purpose: To consider whether to adopt, or amend and adopt, the 1997 Edition of the Uniform Building Code (in three volumes) published by the International Conference of Building Officials, and repeal of the 1994 edition of this code.

Statutory Authority for Adoption: RCW 19.27.031 and 19.27.074.

Statute Being Implemented: Chapters 19.27 and 34.05 RCW.

Summary: The proposed rules include adoption of the 1997 Edition of the Uniform Building code (in three volumes) with amendments, and the repeal of the 1994 edition of this code.

Reasons Supporting Proposal: RCW 19.27.031, 19.27.074.

Name of Agency Personnel Responsible for Drafting and Implementation: Al Rhoades, P.O. Box 48300, Olympia, WA 98504-8300, (360) 586-8999; and Enforcement: Local jurisdictions.

Name of Proponent: Washington State Building Code Council, governmental.

Agency Comments or Recommendations, if any, as to Statutory Language, Implementation, Enforcement, and Fiscal Matters: The council seeks comments on the issues and options proposed in the rules shown below.

Rule is not necessitated by federal law, federal or state court decision.

Explanation of Rule, its Purpose, and Anticipated Effects: The proposed rule will adopt by reference and amend the 1997 Edition of the Uniform Building Code (UBC) published in three volumes by the International Conference of Building Officials (ICBO). The purpose is to replace the 1994 UBC (chapter 51-30 WAC), which will be repealed, and assign the 1997 UBC a new WAC number (chapter 51-40 WAC). The 1997 UBC will be amended to provide greater safety and flexibility than the published version for application in Washington state.

Regulatory Review: In compliance with Executive Order 97-02, Regulatory improvement, the following criteria for regulatory review will be considered at the time of final adoption of the rule.

1. Need. This rule is necessary to comply with the requirements of RCW 19.27.074. The council must regularly review updated versions of the Uniform Building Code, and amend and adopt as deemed appropriate by the council. An updated, 1997 version of the Uniform Building Code has been published. The purpose and objective of this review, as given in RCW 19.27.020, is to promote the health, safety and welfare of the occupants or users of buildings; to require minimum construction standards for the state of Washington; to permit the use of modern technical methods; to eliminate restrictive, obsolete, conflicting, duplicating and unnecessary regulations; and to provide standards to make buildings accessible to and usable by physically disabled persons. The technical advisory groups appointed by the council have identified rules that are obsolete, duplicative or ambiguous, and have proposed amendments and revisions.

2. Effectiveness and Efficiency. The mission of the council is to adopt building codes for uniform application throughout the state. In the course of the regular rule review, the council examined regulatory alternatives and new technologies. The council has identified where alternatives can be used effectively and efficiently. The council efficiently achieves uniform state building codes by serving as the central administrative agency for state-wide adoption of building codes.

3. Clarity. The council is revising their filing procedure for state amendments to the national uniform codes. To enhance clarity, only those subsections with a state amendment will be filed under the main section number. The balance of the main section will remain as written in the national uniform code, as adopted by reference, unless otherwise noted. This reformatting change reorganizes and shortens the WACs, and necessitates new WAC number assignments.

4. Intent and Statutory Authority. The proposed rule is consistent with the legislative intent of the statute chapter 19.27 RCW. The statute gives the council sufficient authority to maintain the state building code, and to amend and adopt new editions of the Uniform Building Code. The Uniform Building Code is published every three years.

5. Coordination. The council rule-making process has included participation by national, state, and local building, fire, mechanical and plumbing officials, as well as state agency representatives for the Departments of Social and Health Services, Health, Labor and Industries, and the state Fire Marshal. The council actively seeks participation from other state agencies to assure that duplication and inconsistency is eliminated.

6. Cost. The council appointed technical advisory groups and an Economic and Regulatory Assessment Committee to examine the costs and benefits associated with the revisions to the building codes.

7. Fairness. The state amendments to the Uniform Building Code proposed by the council are intended to mitigate disproportionate impact on the regulated community. The council is made up of representatives from the regulated community, as well as public and regulatory officials. In addition, the council enlisted the assistance of technical advisory groups, made up of the individuals, organizations and businesses impacted by the building codes, to review code changes and proposals.

Proposal Changes the Following Existing Rules: Most of the amendments to the 1994 UBC have been brought forward and included with the adoption of the 1997 UBC. The few amendments not included are due primarily to changes between the 1994 and 1997 codes, which have incorporated language contained in the previous state amendments. Appropriate editorial changes have been made where needed to provide correct section number references and to reflect the new "means of egress" building exiting system terminology. The amendments added with the adoption of the 1997 UBC are as follows:

WAC 51-40-007 Exceptions, "temporary growing structures" are defined and their regulation is exempted from the UBC.

WAC 51-40-303, 51-40-304, 51-40-305, 51-40-307, 51-40-308, 51-40-310, and 51-40-311, the .5 subsection of each of these sections has an added reference to Chapters 12 and 29 for light, ventilation and sanitation requirements.

WAC 51-40-313, Section 313.2.1.3 has been amended to make it clear that an occupancy separation is not needed between a Group LC, Boarding Home Occupancy and an Group R, Division 1 Occupancy. For Section 313.4.2 an exception has been added to allow waiting and resting areas in Group LC Occupancies to be open to the corridor under certain conditions.

WAC 51-40-405, in Section 405.3.3.2, Option 1 maintains the 1997 UBC language requiring automatic roof vents to be "of an approved type:" Option 2 would require automatic roof vents to be "labeled by an approved agency."

WAC 51-40-904, in Section 904.l.2 an exception is added which removes the requirement for a fire-extinguishing system sprinkler at the top of a noncombustible elevator hoistways whose cars meet the requirements of ASME A17.1, Safety Code for Elevators and Escalators. For Section 904.2.4.1, the existing amendment requiring automatic fire-extinguishing systems in newly constructed school buildings has language added to clarify that substitutions as well as increases are allowed by Sections 505, 506 and 508.

Section 1003.3.4.4, two options are being proposed for this section. Option 1 maintains the existing amendment, requiring landings for ramps steeper than 1:15. Option 2 adopts the 1997 UBC language unamended and requires landings for ramps steeper than 1:20.

Section 1003.4.5, two options are being proposed for this section. Option 1 maintains the existing amendment, requiring handrails for ramps steeper than 1:15. Option 2 adopts the 1997 UBC language unamended and requires handrails for ramps steeper than 1:20.

Section 1007.5.9.1, amend section by deleting the term "and constant" from Item 3, Visual Supervision.

WAC 51-40-1100, Chapter 11, replacing UBC Chapter 11, is retained and moved from chapter 51-30 WAC to chapter 51-40 WAC, with the following proposed changes:

Section 1105.4.4, alter the exception language to bring it in greater compliance with the Americans with Disabilities Act.

Section 1106.3.2, two options are being proposed for this section. Option 1 changes the language to require that all operable parts of environmental and other controls be within the ranges specified in the section, and refers the user to Chapter 10 for the placement of panic hardware. Option 2 maintains the existing code language.

Section 1106.10.7, this section has been deleted. The ADA does not have a requirement for vision panels. This change will not affect certification.

Section 1106.11.3.1, two options are presented for this section. Option 1 allows for an alternate approach width to toilet stalls when a latch side approach is available. Option 2 maintains the existing code language.

Section 1106.27.1, Exception 8, editorial language changes are being proposed to this section.

WAC 51-40-1506, an exception is added to Section 1506.3 which allows building storm drain overflows to be connected to the vertical riser for the roof drain.

WAC 51-40-2900 and 51-40-2929, Chapter 29, Plumbing Systems, has two options, each of which is a rewrite of the chapter. Also, Table 29-A, Minimum Plumbing Fixtures, has been revised to provide more equitable requirements.

WAC 51-40-31200, Standard 31-2, Standard Test Method for Particulate Emissions From Fireplaces, in Section 31.201 the definition of "Masonry Heater" has been revised to be the same as that found in the newly approved ASTM E-1602, which defines masonry heaters and specifies how they should be built.

A small business economic impact statement has been prepared under chapter 19.85 RCW.

Purpose: The purpose of this analysis is to comply with the requirements of chapter 19.85 RCW, to examine whether these proposed rules will have a disproportionate impact on small businesses.

Introduction: The state Building Code Council (council) is proposing to adopt the 1997 Edition of the Uniform Building Code (chapter 51-40 WAC), published by the International Conference of Building Officials. Sanitary Facilities, WAC 51-40-406.7, has been identified by the council's Economic and Regulatory Assessment Committee (ERAC) as having a potential disproportionate cost impact to small business.

The council appointed Technical Advisory Groups (TAGs) to do a comprehensive review and comparison of the 1994 Uniform Building Code and the 1997 Uniform Building Code. The TAGs held meetings over a three year period. All national and state-wide code changes were examined. The TAGs' findings were reviewed by the ERAC. Based on this review, the council found that all changes proposed other than the measure specified in this report are editorial in nature and clarifications of nationally recognized standards, which have minimal economic impact.

The council members and participants are a representative sample of individuals involved in the building construction industry. The makeup of the participants were: Architects, home builders, building officials, contractors, fire officials, energy professionals, manufacturers, engineers, plumbers, state and local officials, inspectors, industry associations and organizations, companies and business, electricians, and the general public.

Summary of Proposed Rule: WAC 52-40-406.7 (Sanitary Facilities), this code change would require all projection rooms to have a lavatory and a water closet, for the purpose of healthy, sanitary facilities. Currently, WAC 52-30-406.7 [52.40.406.] requires a lavatory in every projection room; only in assembly occupancies does the code require a water closet. The new code would require both fixture in all projection rooms.

Industry Analysis: The four-digit Standard Industrial Classification (SIC) codes for the industries potentially impacted are listed below:

[Open Style:Columns Off]

[Open Style:Columns On]

Within each four-digit SIC, data from December 31, 1996, (the most recent) were analyzed to determine the number of small and large businesses, and the number of employees per business. Industry data at the four-digit level, provided by the Employment Security Department, were broad in scope and anonymous. Due to confidentiality laws in the state, the council was not able to analyze businesses on a "per business" or "per employee" basis as established in chapter 19.85 RCW, Regulatory Fairness Act. Therefore an analysis was done based solely on the number of employees per employers within each four-digit SIC.

Example: SIC 1521 (Single-family housing construction) has a total of 5,410 employers and 15,490 employees. Of those 5,410 employers, 5,398 of them were small businesses as defined in chapter 19.85 RCW (fifty employees or less) and twelve were large businesses (fifty-one or more employees). A survey was prepared that described these proposed changes and asked businesses to estimate what they believed the cost impact of these changes would be on their business and how they arrived at that figure. The survey also asked businesses how many workers they employed. The council sent surveys to ten percent of businesses within these identified industries to assess the economic impact of the proposals.

The council is able to provide the following detailed information regarding the potentially impacted businesses.

Number of businesses potentially impacted 10,529

Number of employees potentially impacted 63,258

Average number of employees/business 6

Source: Employment Security Dec. 31, 1996 data.

Cost of Compliance: To determine the costs of reporting and compliance requirements for the identified code change proposals, the council used the results of the surveys along with the committee's economic evaluation as an informational resource. However, of the 1171 surveys sent out only four percent were returned. The returned surveys break down as follows:

Number of small businesses responding

(50 or less employees) 25 (57%)

Average number of employees 7

Estimated average cost of compliance

per employee $1,550

Number of large businesses responding

(51 or more employees) 2 (5%)

Average number of employees 69

Estimated average cost of compliance

per employee No costs were

provided by

large

businesses

Note: Average cost of compliance for large businesses is high due to inadequate sample size. The committee estimates that the cost of compliance falls between $100 - $2000.

Compliance Cost I: Reporting and compliance requirements: There are no reporting and/or compliance requirement costs involved with this proposal.

Compliance Cost II: Associated costs:

[Open Style:Columns Off]

[Open Style:Columns On]

Compliance Cost III: Lost sales or revenue: The council felt that the costs described in "Compliance Cost II" are ultimately passed on to the purchaser of the service. Therefore, this proposal does not have an effect on the business' sales or revenues.

Providing lavatories and water closets in projection rooms with assembly occupancies is currently required by state regulations. Therefore, the new language opens the requirement to all facilities that have projection rooms. This would provide a potential for an increase in sales and revenue to the contractor, because now buildings with projection rooms not in an assembly area would have to comply with this requirement.

Compliance Cost IV: Possible disproportionate effect on small businesses: The Regulatory Fairness Act requires, when possible, a comparison of the compliance costs for small and large businesses required to comply with the proposed rule.

The results of the survey were limited and did provide some insight as to whether the proposed rules have a disproportionate economic impact on small businesses. However, the survey results as well as the committee's opinion both concur that all assembly occupancy projection rooms comply with this requirement currently and it is those projection rooms that are not in assembly occupancies that would have to comply. Obtaining information on the number of nonassembly occupancy projection rooms was not possible. Due to lack of survey data for nonassembly occupancy projection rooms, costs could not be compared but are believed to be of minimal impact.

However, as provided in the table above, the approximate cost of installing a sanitary facility at its most minimal requirements would be in the range of $3,000 to $7,000 (approximately $175 per square foot at forty square feet). These costs would apply to all installations of sanitary facilities.

The survey results were analyzed and it was concluded that a comparison of small business cost to large business cost is not possible. Excerpts from the survey results are shown below:

Involvement of Small Businesses: The council has included small businesses in the drafting of this language and the preparation of the small business economic impact study (SBEIS). Small businesses were represented on the technical advisory groups and council committees. Ten percent of each of the identified SIC industries were solicited for information regarding the potential economic impact of the proposed rules.

Mitigation: Through a formal and established method of negotiated rule-making, the council and the affected industries have considered and mitigated costs associated with the proposed rules. The council solicited feedback from industry. Industry representation has been involved at all public meetings.

The council and its committees are of the opinion that many of the potentially impacted businesses will experience minimal or no extra cost of compliance. Language was drafted so that industry would have adequate time to comply with those sections of the rule that may impose an economic impact on business. Sections or wording of the proposed rules was omitted in an effort to minimize the costs. Again, business representation was an integral part of the review and development of this negotiated rule-making process.

Since the proposed rules have been negotiated into their current form with input from the council and industry, the council is of the opinion that adequate mitigation efforts have been put forth.

Conclusion: Based on the results of the survey and the council's economic evaluation, the council recognized that the proposed rule may impose minimal economic impact on businesses in the building construction industry. However, the council also realizes its obligation to ensure the health, safety and welfare of the occupants or users of buildings and structures and the general public through the provisions of the building codes throughout the state, as stated in the council's legislative mandate.

Again, the council appointed Technical Advisory Groups (TAGs) to do a comprehensive review and comparison of the 1994 Uniform Mechanical Code and the 1997 Uniform Mechanical Code. The TAGs held meetings over a three year period. All national and state-wide code changes were examined. The TAG findings were reviewed by ERAC. Based on this review, the council found that all changes proposed other than the measures specified in this report are editorial in nature and clarifications on nationally recognized standards which have minimal to no economic impact.

In accordance with the Regulatory Fairness Act, the above analysis demonstrates that the proposed rule would not place a disproportionate economic impact on small business when compared to large businesses. Based on the data received from the surveys and the council committee's evaluations of potentially-impacted businesses, this analysis has determined that the development of nonassembly occupancy projection rooms are so few that no significant impact would be imposed to the industry.

PART III - ACCESSIBILITY FOR EXISTING BUILDINGS

NEW SECTION

WAC 51-40-1109 Section 1109--Scope.

Section 1109.1 General. The provisions of this part apply to renovation, alterations, and additions to existing buildings including those identified as historic buildings. This chapter includes minimum standards for removing architectural barriers, and providing and maintaining accessibility for persons with disabilities to existing buildings and their related facilities.

1109.2 Equivalent Facilitation. Departures from specific technical and scoping requirements of this part by the use of alternate methods are permitted where such methods will provide equivalent or greater access to, and usability of, the facility. Alternate methods shall permit individuals with disabilities to approach, enter, and use a site, building, facility or portion thereof; as easily, safely, conveniently, and independently as the specified method.

[]

NEW SECTION

WAC 51-40-1110 Section 1110--Definitions.

Section 1110. For the purpose of this part, certain terms are designated as follows:

ALTERATION is any change, addition, or modification in construction or occupancy.

ALTERATION, SUBSTANTIAL is any alteration, where the total cost of all alterations (including but not limited to electrical, mechanical, plumbing, and structural changes) for a building or facility within any 12-month period amounts to 60 percent or more of the appraised value.

PATH OF TRAVEL means a continuous, unobstructed way of pedestrian passage by means of which an altered area may be approached, entered, and exited, and which connects the altered area with an exterior approach (including sidewalks, streets, and parking areas), an entry to the facility, and other parts of the facility. For the purposes of this part, the term path of travel also includes restrooms, telephones, and water fountains serving the altered area.

TECHNICALLY INFEASIBLE means that an alteration has little likelihood of being accomplished because existing structural conditions would require removing or altering a load-bearing member which is an essential part of the structural frame, or because site constraints prohibit modification or addition of elements, spaces, or features which are in full and strict compliance with the minimum requirements for new construction and necessary to provide accessibility.
