encourage the continued use or reuse of existing buildings and structures. This code is intended to permit repairs, renovations, alterations, reconstructions, additions, and/or changes of occupancy that maintain or improve the health, safety and welfare in existing buildings, without requiring full compliance with the construction requirements of the Building Code, Mechanical Code, Plumbing Code, Rhode Island Fire Safety Code, Rhode Island Fire Prevention Code, Electrical Code, Boiler Safety Code, Energy Code, Elevator Code, or Accessibility Code, except for proportional additional work as specified in this code. Existing buildings, subject to this code, shall continue to be subject to the administrative, maintenance and operational requirements of the above-referenced codes. Building owners shall further comply with the regulations adopted by the Rhode Island Department of Health and all other public bodies charged with protecting the public health and safety. This code shall only apply to buildings in existence for at least ten (10) years prior to the application for a permit under this code. This code shall have an effective date of May 1, 2002. 101.1.1 Uses not covered: All repairs, renovations, alterations, reconstruction, additions and/or conversions (changes of occupancy) to health care facilities, nursing homes, child day care centers, community residences, educational occupancies, detention and correctional occupancies, high hazard occupancies, and one, two, and three family homes shall not be covered or enforced by this code at this time and shall comply with the applicable provisions of the Building Code, Mechanical Code, Plumbing Code, Rhode Island Fire Safety Code, Rhode Island Fire Prevention Code, Electrical Code, Boiler Safety Code, Energy Code, Elevator Code, or Accessibility Code. 101.1.2 The fire code element of this code generally addresses means of egress, fire detection systems, fire suppression systems, and fire-related mechanical, electrical and plumbing systems. In general, the fire code element incorporates national rehabilitation code philosophies by coupling many of the passive fire protection elements of Nationally Applicable Recommended Rehabilitation Provisions developed by HUD and the newly drafted NFPA 5000 Chapter 54 for existing buildings. To achieve a level of active fire protection acceptable to the Fire Service of Rhode Island, this code further incorporates the fire protection elements of the current Rhode Island fire alarm, sprinkler system and related active fire safety systems. 101.1.3 The building code element of this code generally addresses structural, energy, accessibility, boiler and elevator requirements along with all non-fire related mechanical, electrical and plumbing systems. In general, the building code elements incorporate the underlying philosophy of Nationally Applicable Recommended Rehabilitation Provisions developed by HUD and the newly drafted International Existing Building Code and NFPA provisions for the rehabilitation of existing buildings. 101.2 All work shall be classified into six categories: repair, renovation, alteration, reconstruction, addition, and change of occupancy. Specific requirements are established for each work category in this code. Work of more than one category shall be permitted to be part of a single work project. 101.2.1 Where a project includes one category of work in one building area and another category of work in a separate area of the building, each project area shall comply with the requirements of the respective category of work. 101.2.2 Where a project consisting of alterations and reconstruction is performed in the same work area, or in contiguous work areas, the project shall comply with the requirements applicable to a reconstruction. Exception: Where the reconstruction work area is less than ten (10%) percent of the modification work area, the two shall be considered as independent work areas, and the respective requirements shall apply. 1 101.2.3 Nothing in this chapter shall be interpreted as requiring the repair, renovation, alteration or reconstruction of existing buildings which are in compliance with the Building and Fire Codes. If a building was originally inspected and determined not to be in compliance with either the Fire or Building Code, the owner shall have three options: first, the owner may correct the cited deficiencies and bring the building into compliance with the Fire or Building Code provisions in question. The second option would be to apply for an appropriate variance, with either the Fire Board or Building Board. The third option would be to present the authority having jurisdiction a plan of action bringing the facility into compliance with the provisions of this Code. In the case where an owner plans to unilaterally proceed with a repair, renovation, alteration or reconstruction of an existing building, the owner shall submit plans under this Code. Nothing herein shall prevent the owner from submitting plans for review under the current Building Code and Fire Code. 102.0 Compliance 102.1 Categories of work: Repairs, renovations, alterations, reconstruction, additions, and changes of occupancy shall conform to the requirements of this code. 102.2 Equivalent alternatives: This code is not intended to prevent the use of any alternate material, alternate design or alternate method of construction not specifically prescribed herein, provided any alternate has been deemed to be equivalent by the authority having jurisdiction and its use authorized by the Rehabilitation Board. 102.3 Other alternatives: Where compliance with this code or with any other code as required by this code is technically infeasible or would impose undue hardship because of structural, construction or dimensional difficulties, the Rehabilitation Board is authorized to accept other alternative materials, design features and/or operational features. 102.3.1 Notwithstanding the above, the local certified building official, with the approval of the Building Commissioner, may grant limited dimensional modifications from the building code element of this code; and the local certified fire marshal, with the approval of the State Fire Marshal, may grant limited dimensional modifications from the fire code element of this code. The dimensional modifications referred to above would be limited to existing ceiling heights, door widths, window openings, stairway and hallway widths, and the dimensions of stairway treads and risers. The above dimensional modifications may only be granted when the total existing egress width can accommodate the maximum occupancy load. 102.4 Effective date: Requirements of this code, and the requirements of this code that reference the Building Code, Mechanical Code, Plumbing Code, Rhode Island Fire Safety Code, Rhode Island Fire Prevention Code, Electrical Code, Boiler Safety Code, Energy Code, Elevator Code or Accessibility Code shall be based on the respective codes in effect at the time of the issuance of the permit, and not on any subsequent amendments unless the above codes are specifically made retroactive by statute or administrative regulation adopted by the Fire Board, Building Board, or other authorized Board. This code shall only apply to buildings in existence for at least ten (10) years prior to the application for a permit under this code. 102.5 Permit expiration: Every permit issued shall become invalid unless the work on the site authorized by such permit is commenced within 180 days after its issuance, or if the work authorized on the site by such permit is suspended or abandoned for a period of 180 days after the time the work is commenced. One or more extensions of not more than 180 days each shall be permitted when requests are submitted in writing and justifiable cause demonstrated. 102.6 Compliance with other codes: Buildings, elements, components or systems in compliance with the current edition of the Building Code, Mechanical Code, Plumbing Code, Rhode Island Fire Safety Code, Rhode Island Fire Prevention Code, Electrical Code, Boiler Safety Code, Energy Code, Elevator Code, or Accessibility Code shall not be required to comply with any more restrictive requirement of this code. 2 Exception: Required sprinkler and fire alarm systems. 102.7 Elements, components and systems of existing buildings with features that exceed the requirements of the codes for new construction and not otherwise required as part of prior documented approved alternative arrangements shall not be prevented by this code from being modified as long as they remain in compliance with the applicable codes for new construction. 102.8 It is not the intent of this Code to supersede any codes or ordinances that address dangerous or unsafe buildings. 102.9 Work mandated by any accessibility, property, housing, or fire code, or mandated by any licensing rule or ordinance, adopted pursuant to law, shall conform only to the requirements of that code, rule, or ordinance and shall not be required to conform to this chapter unless the code requiring such work so provides. 102.10 Buildings and structures located wholly or partially within the flood hazard area established by the Building Code shall comply with that code. 103.0 Nonconforming Rights (Existing Buildings) 103.1 Buildings in existence at the time of the adoption of this code may have their existing use or occupancy continued, if such use or occupancy was legal at the time of the adoption of this code provided such continued use is not hazardous to life. Nothing in this code shall be interpreted as requiring the repair, renovation, alteration or reconstruction of existing buildings. 104.0 Relationship to Other Codes, Rules, and Ordinances 104.1 It is not the intent of this code to supersede any codes or ordinances that address dangerous or unsafe buildings. 104.2 It is not the intent of this code to supersede any retroactive regulations that impose stricter requirements. 104.3 It is not the intent of this code to supersede the Minimum Housing Code by establishing minimum standards of habitability for housing. 104.4 Work mandated by any of the following codes, rules, or ordinances that is not part of a rehabilitation project shall conform only to the requirements of those codes, rules or ordinances and shall not be required to conform to this code unless the document requiring such work so provides: (1) accessibility, housing, property maintenance; (2) any codes or ordinances that address dangerous or unsafe buildings or conditions; (3) any licensing rule or ordinance, adopted pursuant to law; and (4) Rhode Island Fire Prevention Code. (5) Rhode Island Fire Safety Code. (6) Rhode Island Building Code. 105.0 Preliminary Meeting 105.1 If a building permit is required for a complex rehabilitation project involving multiple codes, then at the request of the prospective permit owner or authorized representative prior to the submission of the 3 construction permit application, the certified building official and the certified fire marshal or their designees, and agency representatives from all necessary agencies in accordance with Section 105.2 to the extent possible, shall meet with the prospective applicant to discuss plans for any proposed work or change of occupancy under this code prior to the application for the permit. 105.2 The preliminary meeting, to the extent possible, shall include the officials responsible for permit approval and enforcement in the following areas, as may be applicable to the rehabilitation project: 1. Building Code; 2. Mechanical Code; 3. Plumbing Code; 4. Electrical Code; 5. Rhode Island Fire Safety Code; 6. Rhode Island Fire Prevention Code; 7. Boiler Safety Code; 8. Energy Code; 9. Elevator Code; 10. State and Local historical preservation ordinances; 11. Accessibility Code. Where possible, a single meeting of all the parties shall be arranged. Where the total cost of the project exceeds five hundred thousand ($500,000) dollars, the officials shall meet onsite if so requested by the owner. 105.3 The purpose of this preliminary meeting is for the prospective applicant to present its intentions for the proposed work to the responsible code officials so that together they can determine the specific requirements in the codes listed in Section 105.2 to be applied to proposed project. Any decisions reduced to writing and agreed to by all parties regarding the specific requirements of the codes listed in Section 105.2 that are to be applied to the proposed project made at the preliminary meeting shall be binding upon the prospective applicant and the code officials unless circumstances arise which were unknown or could not be ascertained by the prospective applicant, the certified building official and/or the certified fire marshal, at the time of the preliminary meeting. Notwithstanding the above, nothing herein shall relieve the applicant of the obligation to fully comply with the provisions of this code in good faith. 105.4 For a rehabilitation project or portion thereof that is in the repair, renovation or alteration category of work, a preliminary meeting may be granted at the discretion of the certified building official and the certified fire marshal when a request for a preliminary meeting is made by the prospective applicant prior to the submission of the construction permit application. 106.0 Permits 106.1 The rehabilitation work area, as defined in Chapter 2, shall be clearly identified on all construction permit applications, construction documents and permits required by certified building official and the certified fire marshal. 107.0 Appeals 107.1 Any appeal of issues under this code shall be heard exclusively by the Joint Committee on Rehabilitation Building Code for Existing Buildings and Structures pursuant to R.I.G.L. 23-29.1-4.

B NOTE: Where the section is followed by the letter "B", "F", or "O", the following meaning shall apply: "B" This means that the Building Official or the Plumbing, Mechanical or Electrical Inspector shall review the plans, issue the permit, inspect the installation, and approve the final certificate. "F" This means that the Fire Official shall review the plans for approval, the Fire Official and/or the Building Official inspects the installation, and the Fire Official observes the final test and approves the final installation. The Building Official shall issue the permits. "O" This would indicate another State agency approval and inspection is needed. An explanation will indicate the agency and approvals needed. 53 Chapter 10: Accessibility 1001.0 General 1001.1 All buildings, with the Exception of those determined to be historical and so certified under the provisions of Chapter 9 of this code, shall further comply with the standards outlined herein. B 1001.2 All buildings certified as historical buildings under the provisions of Chapter 9 of this code shall also comply with the standards herein. BO Exception: Where such modifications to the existing building are determined, by the State Historical Preservation Officer, in writing, to adversely impact the historical significance of the building. In all such cases, the owner shall meet with the State Historical Preservation Officer, the Building Commissioner, and the State ADA Coordinator, or their respective designees, to develop alternative means of compliance with this chapter. 1002.0 Requirements 1002.1 General: Any alteration to a facility covered by this code, after passage of this code, shall be made so as to ensure that, to the maximum extent feasible, the altered portions of the facility are readily accessible to and usable by individuals with disabilities, including individuals who use wheelchairs. B 1002.2 Alteration: For the purposes of this chapter, an alteration is a change to a place of public accommodation or a commercial facility that affects or could affect the usability of the building or facility or any part thereof. B 1002.3 Alterations include, but are not limited to, remodeling, renovation, rehabilitation, reconstruction, historical restoration, changes or rearrangement in structural parts or elements, and changes or rearrangement in the plan configuration of walls and full-height partitions. Normal maintenance, re-roofing, painting or wallpapering, asbestos removal, or changes to mechanical and electrical systems are not alterations unless they affect the usability of the building or facility. B 1002.4 If existing elements, spaces, or common areas are altered, then each such altered element, space, or area shall comply with the applicable provisions of the American with Disabilities Act Accessibility Guidelines (ADAAG). B 1002.5 To the maximum extent feasible: The phrase “to the maximum extent feasible”, as used in this section, applies to the occasional case where the nature of an existing facility makes it virtually impossible to comply fully with applicable accessibility standards through a planned alteration. In these circumstances, the alteration shall provide the maximum physical accessibility feasible. Any altered features of the facility that can be made accessible shall be made accessible. If providing accessibility in conformance with this section to individuals with certain disabilities (e.g., those who use wheelchairs) would not be feasible, the facility shall be made accessible to persons with other types of disabilities (e.g., those who use crutches, those who have impaired vision or hearing, or those who have other impairments). B 1003.0 Alterations: Path of Travel 1003.1 General. An alteration that affects or could affect the usability of or access to an area of a facility that contains a primary function shall be made so as to ensure that, to the maximum extent feasible, the path of travel to the altered area and the restrooms, telephones, and drinking fountains serving the altered area, 54 are readily accessible to and usable by individuals with disabilities, including individuals who use wheelchairs, unless the cost and scope of such alterations is disproportionate to the cost of the overall alteration. B 1003.2 Primary function: A “primary function” is a major activity for which the facility is intended. Areas that contain a primary function include, but are not limited to, the customer services lobby of a bank, the dining area of a cafeteria, the meeting rooms in a conference center, as well as offices and other work areas in which the activities of the public accommodation or other private entity using the facility are carried out. Mechanical rooms, boiler rooms, supply storage rooms, employee lounges or locker rooms, janitorial closets, entrances, corridors, and restrooms are not areas containing a primary function. B 1003.3 Alterations to an area containing a primary function: Alterations that affect the usability of or access to an area containing a primary function include, but are not limited to: B a. Remodeling merchandise display areas or employee work areas in a department store; b. Replacing an inaccessible floor surface in the customer service or employee work areas of a bank; c. Redesigning the assembly line area of a factory; or d. Installing a computer center in an accounting firm. 1003.4 For the purposes of this section, alterations to windows, hardware, controls, electrical outlets, and signage shall not be deemed to be alterations that affect the usability of or access to an area containing a primary function. B 1003.5 Landlord/tenant: If a tenant is making alterations as defined in Section 1002.2 that would trigger the requirements of this section, those alterations by the tenant in areas that only the tenant occupies do not trigger a path of travel obligation upon the landlord with respect to areas of the facility under the landlord’s authority, if those areas are not otherwise being altered. B 1003.6 Path of travel: A “path of travel” includes a continuous, unobstructed way of pedestrian passage by means of which the 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 entrance to the facility, and other parts of the facility. B 1003.7 An accessible path of travel may consist of walks and sidewalks, curb ramps and other interior or exterior pedestrian ramps; clear floor paths through lobbies, corridors, rooms, and other improved areas; parking access aisles; elevators and lifts; or a combination of these elements. B 1003.8 For the purposes of this code, the term "path of travel" also includes the restrooms, telephones, and drinking fountains serving the altered area. B 1003.9 Disproportionality: Alterations 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 (20%) percent of the cost of the alteration to the primary function area. B 1003.10 Costs that may be counted as expenditures required to provide an accessible path of travel may include: B a. 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; B b. Costs associated with making restrooms accessible, such as installing grab bars, enlarging toilet stalls, insulating pipes, or installing accessible faucet controls; B 55 c. 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); B d. Costs associated with relocating an inaccessible drinking fountain. B 1003.11 Duty to provide accessible features in the event of disproportionality:. When the cost of alterations necessary to make the path of 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. B 1003.12 In choosing which accessible elements to provide, priority should be given to those elements that will provide the greatest access, in the following order: B a. An accessible entrance; b. An accessible route to the altered area; c. At least one accessible restroom for each sex or a single unisex restroom; d. Accessible telephones; e. Accessible drinking fountains; and f. When possible, additional accessible elements such as parking, storage, and alarms. 1003.13 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. B 1003.14 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. B 1003.15 Only alterations undertaken after the passage of this chapter shall be considered in determining if the cost of providing an accessible path of travel is disproportionate to the overall cost of the alterations. B 1004.0 Alterations: Elevator Exemption 1004.1 This section does not require the installation of an elevator in an altered facility that is less than three stories or has less than 3,000 square feet per story, except with respect to any facility that houses a shopping center, a shopping mall, the professional office of a health care provider, a terminal, depot, or other station used for specified public transportation, or an airport passenger terminal. B 1004.2 For the purposes of this section, "professional office of a health care provider" means a location where a person or entity regulated by a state to provide professional services related to the physical or mental health of an individual makes such services available to the public. The facility that houses a "professional office of a health care provider" only includes floor levels housing by at least one health care provider, or any floor level designed or intended for use by at least one health care provider. B 1004.3 For the purposes of this section, shopping center or shopping mall means: B 56 a. A building housing five or more sales or rental establishments; or b. A series of buildings on a common site, connected by a common pedestrian access route above or below the ground floor, that is either under common ownership or common control or developed either as one project or as a series of related projects, housing five or more sales or rental establishments. The facility housing a “shopping center or shopping mall” only includes floor levels housing at least one sales or rental establishment, or any floor level designed or intended for use by at least one sales or rental establishment. 1004.4 The exemption provided in Section 1004.1 does not obviate or limit in any way the obligation to comply with the other accessibility requirements established in this subpart. For example, alterations to floors above or below the accessible ground floor must be accessible regardless of whether the altered facility has an elevator. B 1005.0 Removal of Barriers 1005.1 General: A facility covered by this code shall remove architectural barriers in existing facilities, including communication barriers that are structural in nature, where such removal is readily achievable, i.e., easily accomplishable and able to be carried out without much difficulty or expense.

The path of travel requirements of Section 1003 shall not apply to measures taken solely to comply with the barrier removal requirements of this section. B 1005.4.2 If, as a result of compliance with the alterations requirements specified in Section 1005.4.1 the measures required to remove a barrier would not be readily achievable, a public accommodation may take other readily achievable measures to remove the barrier that do not fully comply with the specified requirements. Such measures include, for example, providing a ramp with a steeper slope or widening a doorway to a narrower width than that mandated by the alterations requirements. No measure shall be taken, however, that poses a significant risk to the health or safety of individuals with disabilities or others. B 1005.5 Portable ramps. Portable ramps should be used to comply with this section only when installation of a permanent ramp is not readily achievable. In order to avoid any significant risk to the health or safety of individuals with disabilities or others in using portable ramps, due consideration shall be given to safety features such as non-slip surfaces, railings, anchoring, and strength of materials. B 1005.6 Selling or serving space. The rearrangement of temporary or movable structures, such as furniture, equipment, and display racks is not readily achievable to the extent that it results in a significant loss of selling or serving space. B 1005.7 Limitation on barrier removal obligations. 1005.7.1 The requirements for barrier removal under Section 1005 shall not be interpreted to exceed the standards for alterations in ADAAG. B 58 1005.7.2 To the extent that relevant standards for alterations are not provided in Section 1005, then the requirements of Chapter 10 shall not be interpreted to exceed the standards for new construction in ADAAG.
