ENCLOSURE The Americans with Disabilities Act (ADA) authorizes the Department of Justice to provide technical assistance to individuals and entities that have rights or responsibilities under the Act. This code comparison was prepared by the staff of the Public Access Section to provide informal guidance to assist the Washington State Building Code Council to compare its code requirements to the requirements of the ADA. However, this technical assistance does not constitute a determination by the Department of the Council's rights or responsibilities under the ADA, and it is not binding on the Department. (This document was originally in CHART format - however - due to ASCII formatting, it now appears as follows:) ADA Requirements 1. Purpose. This document sets guidelines for accessibility to places of public accommodation and commercial facilities by individuals with disabilities. These guidelines are to be applied during the design, construction, and alteration of such buildings and facilities to the extent required by regulations issued by Federal agencies, including the Department of Justice, under the Americans with Disabilities Act of 1990. The technical specifications 4.2 through 4.35 of these guidelines are the same as those of the American National Standard Institute's document A117.1-1980, except as noted in this text by italics. However, sections 4.1.1 through 4.1.7 and sections 5 through 10 are different from ANSI Al17.1 in their entirety and are printed in standard type. The illustrations and text of ANSI Al17.1 are reproduced with permission from the American National Standards Institute. Copies of the standard may be purchased from the American National Standards Institute at 1430 Broadway, New York, New York 10018. Washington State Regulations 51-20-002 Purpose.

Commentary 16 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.1 (2) Continued. 4.1.1 (3)* Areas Used Only by Employees as Work Areas. Areas that are used only as work areas shall be designed and constructed so that individuals with disabilities can approach, enter, and exit the areas. These guidelines do not require that any areas used only as work areas be constructed to permit maneuvering within the work area or be constructed or equipped (i.e., with racks or shelves) to be accessible. Washington State Regulations 51-20-3152 TABLE NO. 31-B REQUIRED TYPE A DWELLING UNITS Total Number of Dwelling Required Number of Type A Units on Site Dwelling Units 0-10 None 11-20 1 21-40 2 41-60 3 61-80 4 81-100 5 For every 20 units or fractional 1 additional part thereof, over 100 51-20-3101 (c) Maintenance of Facilities. Any building, facility, dwelling unit or site which is constructed to be accessible or adaptable under this chapter shall be maintained accessible and/or adaptable during its occupancy. See Occupancy Groups above. Commentary PNE The language above implies all areas are to be accessible in most occupancies, but in some occupancies it is specific (i.e., "paved work areas" in agricultural buildings). We need clarification regarding employee areas. 17 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.1 (4) Temporary Structures. These guidelines cover temporary buildings or facilities as well as permanent facilities. Temporary buildings and facilities are not of permanent construction but are of extensively used or are essential for public use for a period of time. Examples of temporary buildings or facilities covered by these guidelines include, but are not limited to: reviewing stands, temporary classrooms, bleacher areas, exhibit areas, temporary banking facilities, temporary health screening services, or temporary safe pedestrian passageways around construction sites. Structures, sites and equipment directly associated with the actual processes of construction, such as scaffolding, bridging, material hoists, or construction trailers are not included. Washington State Regulations 51-20-3103 Building Accessibility (a) Where required. 1. General. Accessibility to temporary or permanent buildings or portions thereof shall be provided for all occupancy classifications except as modified by this chapter. See also Appendix Chapter 31. 51-20-3103 (a) 1. EXCEPTION 3. Temporary structures, sites and equipment directly associated with the construction process such as construction site trailers, scaffolding, bridging or material hoists are not required to be accessible. 51-20-0104 (e) Moved Buildings and Temporary Buildings. Buildings or structures moved into or within the jurisdiction shall comply with the provisions of this code for new buildings or structures. Temporary structures such as reviewing stands and other miscellaneous structures, sheds, canopies or fences used for the protection of the public around and in conjunction with construction work may be erected by special permit from the building official for a limited period of time. Such buildings or structures need not comply with the type of construction or fire-resistive time periods required by this code. Temporary buildings or structures shall be completely removed upon the expiration of the time limit stated in the permit. Commentary PNE Two concerns exist. WSR appears to exempt reviewing stands and temporary safe pedestrian walkways around a building site. We need an interpretation as to whether 51-20-0104(e) applies here. If so, WSR does not appear to be equivalent. 18 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.1 (5) General Exceptions. (a) In new construction, a person or entity is not required to meet fully the requirements of these guidelines where that person or entity can demonstrate that it is structurally impracticable to do so. Full compliance will be considered structurally impracticable only in those rare circumstances when the unique characteristics of terrain prevent the incorporation of accessibility features. If full compliance with the requirements of these guidelines is structurally impracticable, a person or entity shall comply with the requirements to the extent it is not structurally impracticable. Any portion of the building or facility which can be made accessible shall comply to the extent that it is not structurally impracticable. 4.1.1 (5) (b) Accessibility is not required to (i) observation galleries used primarily for security purposes; or (ii) in non-occupiable spaces accessed only by ladders, catwalks, crawl spaces, very narrow passageways, or freight (non-passenger) elevators, and frequented only by service personnel for repair purposes; such spaces include, but are not limited to, elevator pits, elevator penthouses, piping or equipment catwalks. Washington State Regulations 51-20-3101 (e) Modifications. Where full compliance with this chapter is impractical due to unique characteristics of the terrain, the building official may grant modifications in accordance with Section 106, provided that any portion of the building or structure that can be made accessible shall be made accessible to the greatest extent practical. 51-20-3103 (a) 1. EXCEPTIONS: 2. In other than Group B. Occupancies; Group B, Division 2 retail Occupancies; terminals, depots and other stations used for transportation; buildings owned or operated by a government agency; and the professional offices of health care providers, floors above and below fully accessible levels that have areas less than 3000 square feet per floor, need not be accessible provided that the primary entry level provides facilities as required by Section 3105 equivalent to those located on the nonaccessible levels. 51-20-3103 (b) 2. EXCEPTION: For sites where natural terrain or other unusual property characteristics do not allow the provision of an accessible route of travel from the public way to the building, the point of vehicular debarkation may be substituted for the accessible entrance to the site. 51-20-3105 (a) General. . . Where specific floors of a building are required to be accessible, the requirements shall apply only to the facilities located on accessible floors. 51-20-3103 (a) 1. EXCEPTIONS: 1. Floors or portions of floors not customarily occupied, including, but not limited to, elevator pits, observation galleries used primarily for security purposes, elevator penthouses, nonoccupiable spaces accessed only by ladders, catwalks, crawl spaces, very narrow passageways, or freight elevators, piping and equipment catwalks and machinery, mechanical and electrical equipment rooms. Commentary NE Standards under ADAAG and WSR are not the same. A general exception to all accessibility provisions is allowed for floors with less than 3,000 square feet per floor above and below the accessible level in most occupancies. The elevator exception was expanded. This provision is restated in 51-20-3105(a) General. NE WSR uses the term "impractical" rather than the more restrictive term, "impracticable," used in the ADA regulations. NE The use of "not customarily occupied" and use of other exceptions as examples appears to expand this exception. Example: A basement used for storage, if "occupiable," would be a story under ADAAG. Further, the use of machinery, mechanical and electrical equipment rooms as example expands the exception to include spaces not exempt under ADA. Clarification of this provision is needed. 19 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.2 (3) All objects that protrude from surfaces or posts into circulation paths shall comply with 4.4. 4.1.2 (4) Ground surfaces along accessible routes and in accessible spaces shall comply with 4.5. 4.1.2 (5) (a) If parking spaces are provided for self-parking by employees or visitors, or both, then accessible spaces complying with 4.6 shall be provided in each such parking area in conformance with the table below.

Accessible units shall be identified by the International Symbol of Accessibility. EXCEPTION: Portable toilet units at construction sites used exclusively by construction personnel are not required to comply with 4.1.2(6). Washington State Regulations 51-20-3106 (k) 1. General. Bathrooms, toilet rooms, bathing facilities and shower rooms shall be designed in accordance with this section. (3106). Commentary PNE It is not clear whether portable toilets are covered under temporary buildings, If not, they are not covered. An interpretation is needed. 23 ADA / Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.2 (7) Building Signage.

In assembly areas, a sign notifying the general public of the availability of accessible seating and assistive listening systems shall be provided at ticket offices or similar locations. Commentary 24 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.3 Accessible Buildings New Construction. Accessible buildings and facilities shall meet the following minimum requirements: (1) At least one accessible route complying with 4.3 shall connect accessible building or facility entrances with all accessible spaces and elements within the building facility. 4.1.3 (2) All objects that overhang or protrude into circulation paths shall comply with 4.4. 4.1.4 (3) Ground and floor surfaces along accessible routes and in accessible rooms and spaces shall comply with 4.5. 4.1.3 (4) Interior and exterior stairs connecting levels that are not connected by an elevator, ramp, or other accessible means of vertical access shall comply with 4.9. Washington State Regulations 51-20-3106 Accessible Design and Construction Standards. (a) General. Where accessibility is required by this chapter, it shall be designed and constructed in accordance with this section, unless otherwise specified in this chapter. 51-20-3103 (b) 2. Accessible Route of travel. When a building or portion of a building is required to be accessible, an accessible route of travel shall be provided to all portions of the building, to accessible building entrances an connecting the building and the public way. Except within and accessible dwelling unit, the accessible route of travel to areas of primary function may serve but shall not pass through kitchens, storage rooms, toilet rooms, bathrooms, closets or other similar spaces. Accessible routes of travel serving any accessible space element shall also serve as a means of egress for emergencies or connect to an area of evacuation assistance.... 51-20-3106 (e) Protruding Objects. Protruding objects shall not reduce the clear width of an accessible route of travel or maneuvering space. Any wall- or post-mounted object with its leading edge between 27 inches and 79 inches above the floor may project not more than 4 inches into the required width within a corridor. Any wall-or post-mounted projection greater than 4 inches shall extend to the floor. Protruding objects shall not reduce the clear width of an accessible route of travel or maneuvering space. 51-20-3106 (d) 5. A. General. All floor and ground surfaces in an accessible route of travel shall comply with Section 3106 (q). 51-20-3306 Stairways. (a) General. Every stairway having two or more risers serving any building of portion thereof shall conform to the requirements of this section. When aisles in assembly rooms have steps, they shall conform with the provisions in Section 3315. 51-20-3106 (i) Stairways. 1. General. Stairways required to be accessible shall comply with section 3306 and provisions of this section. Commentary PNE Although WSR appears to apply some provisions to all steps allowed in building code (single risers are not allowed), there is no specific scoping to trigger the requirements contained in 3106 (i). 25 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.3 (5)* One passenger elevator complying with 4.10 shall serve each level, including mezzanines, in all multi-story buildings and facilities unless exempted below. If more than one elevator is provided, each full passenger elevator shall comply with 4.10. EXCEPTION 1. Elevators are not required in facilities that are less than three stories or that have less than 3000 square feet per story unless the building is a shopping center, a shopping mall, or the professional office of a health care provider, or another type of facility as determined by the Attorney General. The elevator exemption set forth in this paragraph does not obviate or limit in any way the obligation to comply with the other accessibility requirements established in section 4.1.3. For example, floors above or below the accessible ground floor must meet the requirements of this section except for elevator service. If toilet or bathing facilities are provided on a level not served by an elevator, then toilet or bathing facilities must be provided on the accessible ground floor. In new construction if a building or facility is eligible for this exemption but a full passenger elevator is nonetheless planned, that elevator shall meet the requirements of 4.10 and shall serve each level in the building. A full passenger elevator that provides service from a garage to only one level of a building or facility is not required to serve other levels. EXCEPTION 2: Elevator pits, elevator penthouses, mechanical rooms, piping or equipment catwalks are exempted from this requirement. EXCEPTION 3: Accessible ramps complying with 4.8 may be used in lieu of an elevator. Washington State Regulations 51-20-3105 (c) Elevators. 1. Where Required. In multi- story buildings or portions thereof required to be accessible by Section 3103, at least one elevator shall serve each level, including mezzanines. Other than within an individual dwelling unit, when an elevator is provided but not required, it shall be accessible. EXCEPTIONS: 1. In Group R. Division 1 apartment occupancies, an elevator is not required where accessible dwelling units and guest rooms are accessible by ramp or by grade level route of travel. 2. In a building of fewer than three stories an elevator is not required where ramps, grade-level entrances or accessible horizontal exits from an adjacent building, are provided to each floor. 3. In multistory parking garages, an elevator is not required where an accessible route of travel is provided from accessible parking spaces on levels with accessible horizontal connections to the primary building served. 4. In Group R, Division 1 hotels and lodging houses less than 3 stories in height, an elevator is not required provided that accessible guest rooms are provided on the ground floor. 51-20-3103 (a) 1. EXCEPTION 2. In other than Group R Occupancies; Group B, Division 2 retail Occupancies; terminals, depots and other stations used for transportation; buildings owned or operated by a government agency; and the professional offices of health care providers, floors above and below fully accessible levels that have areas of less than 3000 square feet per floor, need not be accessible provided that the primary entry level provides facilities as required by Section 3105 equivalent to those located on the nonaccessible levels. Commentary NE Problem #1 Scoping - Elevator exception is expanded to become a general exception to access provisions on floors with less than 3,000 square feet. However, except for this one problem, WSR's elevator exception is more restrictive because it does not apply to two story buildings with unlimited floor space as does ADAAG. Problem #2 Design - Design requirements are not available for review. 27 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.3 (5)* Continued. EXCEPTION 4: Platform lifts (wheelchair lifts) complying with 4.11 of this guideline and applicable state or local codes may be used in lieu of an elevator under the following conditions: (a) To provide an accessible route to a performing area in an assembly occupancy. (b) To comply with the wheelchair viewing position line-of- sight and dispersion requirements of 4.33.3. (c) To provide access to incidental occupiable spaces and Rooms which are not open to the general public and which house No more than five person, including but not limited to equipment Control rooms and projection booths.

Where more than one elevator is provided in the building, elevators used exclusively for movement of freight. 51-20-3105 (c) 2....Elevators required to be accessible shall be designed and constructed to comply with Chapter 296-81 of the Washington Administrative Code. 51-20-3105 (c) 3. Platform Lifts. Platform lifts may be used in lieu of an elevator under one of the following conditions subject to approval by the building official: 1. (sic) To provide an accessible route of travel to a performing area in a Group A. Occupancy; or, 2. (sic) To provide unobstructed sight lines and distribution for wheelchair viewing positions in Group A Occupancies; or, 3. (sic) To provide access to spaces with an occupant load of less than 5; or 4. (sic) To provide access where existing site constraints or other constraints make use of a ramp or elevator infeasible. All platform lifts used in lieu of an elevator shall be capable of independent operation and shall comply with Chapter 296-81 of the Washington Administrative Code. Commentary NE Design requirements are not available for review. NE WSR does not restrict use of a lift to areas with an occupant load of less than 5 that are not open to the public. NE Design requirements are not available for review. 28 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4.1.3 (7) Doors: (a) At each accessible entrance to a building or facility, at least one door shall comply with 4.13. 4.1.3 (7) (b) Within a building or facility, at least one door at each accessible space shall comply with 4.13. 4.1.3.(7) (c) Each door that is an element of an accessible route shall comply with 4.13. 4.1.3 (7) (d) Each door required by 4.3.10, Egress, shall comply with 4.13. 4.1.3 (8) In new construction, at a minimum, the requirements in (a) and (b) below shall be satisfied independently: (a) (i) At least 50% of all public entrances (excluding those in (b) below) must be accessible. At least one must be a ground floor entrance. Public entrances are any entrances that are not loading or service entrances. (ii) Accessible entrances must be provided in a number at least equivalent to the number of exits required by the applicable building/fire codes. (This paragraph does not require an increase in the total number of entrances planned for a facility.) (iii) An accessible entrance must be provided to each tenancy in a facility (for example, individual stores in a strip shopping center). One entrance may be considered as meeting more than one of the requirements in (a). Where feasible, accessible entrances shall be the entrances used by the majority of people visiting or working in the building. Washington State Regulations 51-20-3304 Doors. (a) General. This section shall apply to every exit door serving an area having an occupant load of 10 or more, or serving hazardous rooms or areas, except that Subsection (c), (i), (j) and (k) shall apply to all exit doors regardless of occupant load. Buildings or structures used for human occupancy shall have at least one exterior exit door that meets the requirements of Subsection (f). Doors and landings at doors which are located within an accessible route of travel shall also comply with Chapter 31. 51-20-3103 (b) 3. Primary Entry Access. At least 50% of all public entries, or a number equal to the number of exits, required by Section 3303 (a), whichever is greater, shall be accessible. One of the accessible public entries shall be the primary entry to the building. At least one accessible entry must be ground floor entrance. Public entries do not include loading or service entries. EXCEPTION: In Group R. Division 1 apartment buildings only the primary entry need to accessible, provided that the primary entry provides an accessible route of travel to all dwelling units required to be accessible. 51-20-3103 (b) 3. Where a building is designed not to have common or primary entries, the primary entry to each individual dwelling unit required to be accessible, and each individual tenant space, shall be accessible. 51-20-3103 (b) 3... One of the accessible public entries shall be the primary entry to a building. At least one accessible entry must be a ground floor entrance. Public entries do not include loading or service entries. Commentary PNE ADAAG does not allow the exception for apartment buildings, some of which may be used as transient lodging (i.e., short term condominium rentals and certain timeshare units). It is recognized that the majority of condominiums and timeshare units will not be used as transient lodging. 28 ADA/Washington State May 14, 1993 Technical Assistance Document ADA Requirements 4,1.3 (8)(b) (i) In addition, if direct access is provided for pedestrians from an enclosed parking garage to the building, at least one direct entrance from the garage to the building must be accessible. (ii) If access is provided for pedestrians from a pedestrian tunnel or elevated walkway, one entrance to the building from each tunnel or walkway must be accessible. One entrance may be considered as meeting more than one of the requirements in (b). Because entrances also serve as emergency exits whose proximity to all parts of buildings and facilities is essential, it is preferable that all entrances be accessible. 4.1.3 (8) (c) If the only entrance to a building, or, tenancy in a facility, is a service entrance, that entrance shall be accessible. 4.1.3 (8) (d) Entrances which are not accessible shall have directional signage complying with 4.30.1. 4.30.2, 4.30.3 and 4.30.5, which indicates the location of the nearest accessible entrance. Washington State Regulations 51-30-3103 (b) 2. . . .
