REHABILITATION CODE

 

1 – Introduction:  Using this Subcode

(a)                This section is a guide to the use of the rehabilitation subcode, it should not be interpreted as containing substantive requirements and it is not intended to be cited for enforcement purposes.

1.                  The provisions of the other subcodes of the 1996 BOCA National Building Code do not apply to work in existing buildings, changing the use of an existing building or work in an existing building related to an addition unless the provisions of this subcode specifically referenced them and make them applicable.

2.                  Traditionally, the Shawnee adopted Construction Code (BOCA) has made the requirements that are applicable to new buildings also apply to buildings whose use is changed; applicable to buildings undergoing rehabilitation with the extent of the requirements depending on the amount of money being spent on the building; and to some extent applicable to existing buildings that have an addition constructed.  Buildings whose use was changed and buildings receiving rehabilitation costing more than 50% of the replacement cost of the building were required to comply with all the provisions of the BOCA Building Code for new buildings.

3.                  This subcode takes a new approach.  The requirements that apply to a project are based upon the type of work being done rather than on the extent of the work.  There is only one exception to this rule.  In the case of reconstruction work, as the term reconstruction is defined in this subcode, there are some requirements which must be met when the project is a large one in floor area.  There are no requirements in this subcode that are based on the cost of the work.

4.                  In this subcode, work is classified into six categories.  Each category has a separate section, which describes the requirements for that category of work.  The categories are repair, renovation, alteration, reconstruction, change of use and additions.  These terms are defined in Section 7-3.3 of this subcode.  The definitions are critical to understand the distinctions between these six categories of work.  Where a project contains more than one category of work, each applicable category must be consulted for the requirements for that category of work.

(b)               Repair work:  the requirements that apply to repair work are in Section7-3.4 of this subcode.  The requirements for repairs are brief due to the limited nature of the work.  There is a short list of materials that may not be used for repair work due to their inherently hazardous nature and another list of materials, which must be used in connection with repair work where applicable.  These lists should be used when planning the repair components of any project.

1.                  This subcode does not establish when a permit is required for a project. Those requirements are in Sec. 107.1 of the BOCA/1996 and other adopted city Ordinance. Building Code.  Although it is generally true that repair work undertaken by itself does not require a construction permit, it is important to understand that any repair work undertaken in connection with a project that involves other categories of work is required to meet only the provisions for the repair category established by this subcode.  There is no limit to the amount of repair work, which may be undertaken.  The decision to renovate rather than repair is made only by the owner.

(c)                Renovation Work:  The requirements that apply to renovation work are in Section 7-3.5 of this subcode.  Renovation is defined in Section 7-3.3 of this subcode.

1.                  There are short lists of materials that may not be used and materials or practices, which must be used, where applicable, when renovation work is undertaken.  These lists should be used when planning a project, which involves renovation work.

2.                  The installation of smoke detectors is required in any building of Use Groups R-3/R-4 which undergoes a renovation.

3.                  Renovation work must comply with Section 7-3.8, Materials and Methods.  All materials used for the renovation work must meet the standards for those materials established by Section 7-3.8 and methods of installation must comply with Section 7-3.8.  Section 7-3.8, Materials and Methods, references and makes applicable to renovation work certain specified subsections of the other subcodes of the BOCA Building Code.  Only those subsections specifically referenced in Section 7-3.8 apply to renovation work.  All materials and methods used in renovation work must comply with the requirements.

4.                  This subcode never requires renovation.  Any existing work may be repaired.  The requirements for renovation apply only where the owner decides to renovate.

(d)               Alteration Work:  The requirements that apply to alteration work are in Section 7-3.6 of this subcode.  Alteration is defined in Section 7-3.3 of this subcode.

1.                  Section 7-3.6, alteration work, contains short lists of materials that may not be used and materials or practices which must be used, where applicable, when alteration work is undertaken.  These lists should be used when planning a project, which includes alteration work.

2.                  The installation of smoke detectors is required in any building of Use Group R-3/R-4 which undergoes an alteration.

3.                  Alteration work must also comply with Materials and Methods that are set forth in Section 7-3.8.

4.                  In alteration work, the configuration of the building is changed in some manner.  The definition of “alteration” in Section 7-3.3 of this subcode provides the information needed to fully understand this term.  Because improper alteration work could create a safety hazard in the building, this subcode contains specific requirements, which define these hazards.  These are the Basic Requirements of the subcode, which can be found in Sections 7-3.10 through 7-3.30 of this subcode.

5.                  The subcode includes Basic Requirements, listed by use group, with the exception of egress capacity, interior finish requirements, commercial cooking operations, and windowless stories which apply to all use groups.  Reference should be made to the list of basic requirements applicable to the particular use group in which the building being altered falls.  Care should be taken to ensure that the alteration does not create a non-conformity with any of the basic requirements which did not exist before the alteration was undertaken.

6.                  Certain alterations create what are defined to be new building elements.  There is a specific listing of those items, which are to be treated as newly-created building elements, which can be found in Section 7-3.9 of this subcode.  The elements on that list are required to conform to certain specific sections of the other subcodes of the BOCA Building Code.  The sections with which each newly-constructed element must comply are listed in Section 7-3.9. Any alteration, which creates one of the elements listed in Section 7-3.9, must comply with the specific requirements listed in Section 7-3.9.

7.                  Improvements to the accessibility of buildings may be required when alteration work is undertaken.  Those requirements are specified in Section 7-3.6 (e) and (i) of this subcode.

(e)                Reconstruction Work:  The requirements that apply to reconstruction work are in Section 7-3.7 of this subcode.  Reconstruction is defined in section 7-3.3 of this subcode.  Unlike repair, renovation, and alteration, reconstruction is not a kind of work.  A reconstruction may, as the definition of the term makes clear, include a combination of repair, renovation, and alteration work.  It is the extent and nature of the work, which makes a project a reconstruction.  A project becomes a reconstruction when the area where the project is taking place cannot be occupied while the work is in progress and when a new certificate of occupancy is required before the area can be re-occupied.  Both criteria muse be met.

1.                  This subcode requires that a reconstruction project have a delineated work area.  This area is established by the permit applicant.  The term “work area” is defined in Section 7-3.3 of the subcode.  A reconstruction project must always involve an entire use, primary function space, or tenancy as those three terms are defined in Section 7-3.3.  Projects, which do not involve an entire use, primary function space, or tenancy, are not reconstruction projects.

2.                  Although a reconstruction project is compromised of repair, renovation and alteration work, all of the requirements that apply are found in Section 7.  For ease of use, this section has been written to include all of the requirements applicable to reconstruction.  The entire work area must conform to the Basic Requirements in Section 7-3.10 through 7-3.30 of the subcode.  These sections must be carefully reviewed when a reconstruction project is being planned.

3.                  The Basic Requirements are organized by individual use groups in Sections 7-3.12 through 7-3.28.  Only the sections relevant to the building’s use group must be consulted.  Where a project involves mixed uses, then the special provisions of Section 7-3.29 should also be consulted.  Basic requirements that apply to all use groups are in Section 7-3.11 and 7-3.30 of the subcode.  These sections must be carefully reviewed when a reconstruction project is being planned.

4.                  In addition to meeting the Basic Requirements, certain reconstruction projects must meet the Supplemental Requirements found in Sections 7-3.10 through 7-3.30.  There is a specific section for use group as is the case with the Basic Requirements.  Supplemental Requirements that apply to all use groups are in Sections 7-3.11A and 7-3.30.  The Supplemental Requirements apply only when the work area for a reconstruction project exceeds a certain size.  Each Supplemental Requirement has its own threshold of applicability.

5.                  The owner of a building in which a reconstruction project is planned must review the Supplemental Requirements applicable to the use of the project to determine if any of those requirements applies to the project.  In addition to the specific use group section between 7-3.12A and 7-3.28A, Section 7-3.11A and 7-3.30 should be consulted for he Supplemental Requirements that apply to a project.

5.Applying the Subcode to a Project:  The requirements of this subcode applicable to a project can be found as follows:

6.                  Separate the project into its component parts of repair, renovation, and alteration.

7.                  Where a portion of the work is repair, consult the repair section of the subcode (Section 7-3.4) to ensure that prohibited materials are not being used and that any applicable required materials or practices are being used.

8.                  Where a portion of the work is renovation:

i.                     Consult the renovation sections of this subcode (Section 7-3.5);

ii.                   Ensure that the renovation work does not use any prohibited materials and that any applicable required materials or practices are being used; and

iii.                  Ensure that renovation materials and the methods of their installation conform to the Materials and Methods section of this subcode (Section 7-3.8).

9.                  Where a portion of the work is alteration work:

i.                     Consult the alteration section of this subcode (Section 7-3.6);

ii.                   Ensure that the alteration work does not use any prohibited materials and that any applicable required materials or practices are being used;

iii.                  Ensure that any materials and methods used for the alterations conform to the requirements of the Materials and Methods section of this subcode (Section 7-3.8);

iv.                 Ensure that alteration which creates a new building element listed in Section 7-3.9 of this subcode conforms to the requirements for new building elements that are specified in Section 7-3.9; and

v.                   Ensure that none of the alteration work creates a new condition which would create a violation on any of the Basic Requirements applicable to the use group that are specified in Sections 7-3.10 through Section 7-3.30.

10.              Determine whether the project is a reconstruction project according to the definitions in Section 7-3.3 of the subcode.  When the project is a reconstruction project:

i.                     Establish the work area of the project and show it on the plans and/or permit application;

ii.                   Ensure that the requirements applicable to the repair, renovation, and alteration portions of the project are followed;

iii.                  Ensure that the Basic Requirements for the particular use that are specified in the relevant section of this subcode between 7-3.12 and 7-3.28 are followed.  Where the project work area includes more than one use group, then Section 7-3.29 should be consulted; and

iv.                 Review the size of the work area against the relevant provisions for the Supplemental Requirements in Section 7-3.11A through 7-3.28A of this subcode.  Where compliance with a supplemental requirement is necessary, then ensure that the plans and/or permit application reflect compliance with the required section.  Some Supplemental Requirements will require work outside the work area.

(f)                 Change of Use:  The BOCA Building Code divides all buildings into categories called uses.  The Rehabilitation Subcode uses these same classifications.

1.                  The different uses represent different hazards and different needs.  Specific requirements apply to each use.  Each of the other technical subcodes of the BOCA Building Code:  Building, Fire, Plumbing, Electrical, and Mechanical, defines these uses, each for its own purpose.  Traditionally, the BOCA Building Code required any building or portion of a building where the use was changed to conform to the requirements of the code for a new building of that use.  This subcode takes a different approach.

2.                  A change of use in a building often, but not always, involves some construction work.  Changes of use, in which the owner does not need any construction work to affect the new use, do happen.  The different uses defined by the code reflect different levels of hazard and different safety requirements.  Depending upon the specific change, a new use may not affect the hazard; it could pose a lesser hazard; or it might pose a greater hazard or necessitate additional safety measures.

3.                  This subcode allows changes of use where the new use is similar to or less demanding in terms of hazard or safety requirements than the present use.  No modifications to the building are required by this subcode where such a change of use is planned.

4.                  This subcode uses the concept of Hazard Indexes in order to specify the requirements for a change of use.  Separate hazard indexes are established for different aspects of building, health, and safety:

i.                     Basic Requirements:  Changes of use specified in Section 7-3.31(b) must comply with the Basic Requirements set forth in Section 7-3.10 through 7-3.30 of this subcode before the building can be occupied for the new use.

ii.                   Means of Egress:  Certain changes of use specified in Section 7-3.31(c) must comply with additional requirements for egress which are set forth in Section 7-3.31 before the building can be occupied for the new use.

iii.                  Vertical Openings:  Stairways and other vertical openings located in a building or portion of a building where there is a change of use are required to meet certain enclosure requirements for the new use, which are specified in Sections 7-3.12 through 7-3.28 of this Subcode.  These requirements must be met before the building may be occupied for the new use.

iv.                 Height and Area Limits:  Changes of use are not allowed if the building will exceed the height and area limits specified in Section 7-3.31(e) for its type of construction.  The types of construction are defined in the BOCA/1996 Building Code.

v.                   Exterior Walls:  Changes of use as specified in Section 7-3.31(f) of this subcode must have the fire resistance of exterior walls and any openings therein improved as specified in Section 7-3.31(f) before the building can be occupied for the new use.

vi.                 Fire Suppression:  Changes of use as specified in Section 7-3.31(g) must have a fire suppression system installed in accordance with the requirements of Section 7-3.31(g) before the building can be occupied for new use.

vii.                Fire Alarms and Fire Detection Systems:  Changes of use as specified in Section 7-3.31(h), (i), and (j) must have fire alarms or fire detection installed in accordance with the requirements of Section 7-3.31 (h), (i), and (j) before the building can be occupied for the new use.

viii.              Structural, Plumbing, Electrical, and Mechanical:  Some changes of use may necessitate changes to the structural, plumbing, electrical, or mechanical systems of a building.  These requirements are set forth in Section 7-3.31(k), (l), (m) and (n) of this subcode.  Only those requirements necessitated by the change and needed for health or safety in the new use as specified must be met.

ix.                 Accessibility Requirements:  Changes of use must conform to the accessibility requirements specified in Section 7-3.31 before the building can be occupied for the new use.

5.                  Where the owner of a building undergoing a change of use decides to undertake work not required by Section 7-3.31 of this subcode, then that work must comply with the requirements for repair, renovation, alteration, and reconstruction, as the case may be, which are established by Sections 7-3.4, 7-3.5, and 7-3.7 of this subcode.

6.                  Where the use of a building or portion of a building is changed, a new certificate of occupancy is required for the use by the provision of Subchapter 2 of this code.  This does not mean that all changes of use are required to meet the requirements for Reconstruction.  Only a project, which meets the definition of Reconstruction set forth in Section 7-3.3, need comply with the provisions of Section 7-3.7, Reconstruction, of this subcode.

(g)                Additions:  Additions are required to comply with the provision of the other         technical subcodes of the BOCA Building Code.  Work in the existing building, which is related to the addition, must conform with the requirements of Section 7-3.32 of this subcode.  Additionally, such work undertaken in the existing building must comply with the requirements for repair, renovation, alteration, and reconstruction as set forth in Sections 7-3.4, 7-3.5, 7-3.6, and 7-3.7 of this subcode.

(h)                Historical Buildings:  Section 7-3.33 of this subcode defines those buildings which are to be treated as historic and sets forth certain special requirements applicable to historic buildings which modify the provisions of this subcode when a building is historic.  Section 7-3.33 should be reviewed to determine if a building is to be treated as historic under this subcode and for the special provisions applicable to the various types of historical buildings.

2 – Applicability and Compliance

(a)                This subchapter, adopted pursuant to State law references-Adoption of technical codes, 11 O.S. 14-107; and entitled “Rehabilitation Code”, shall be known and may be cited throughout the regulation as S.A.S.C. 7-3, and when referred to in subchapter 7-3 of this chapter, may be cited as “this subchapter” or “this subcode”.  Unless otherwise specifically provided, all references to article or section numbers, or to provisions not specifically identified by number, shall be construed to refer to such article, section or provision of this subchapter.

(b)               Scope:  Except as otherwise specified, this subchapter shall control all matters concerning the repair, renovation, alteration, reconstruction, change of use, and addition to all buildings and structures and their service equipment as defined herein and shall apply to all existing buildings and structures in the City of Shawnee.

1.                  This subchapter shall not be applied to any building or portion thereof that has never been occupied.  In such building or spaces, the requirements of the other subcodes of the BOCA Building Code for new construction shall apply.

2.                  All work shall be classified by the construction official, in consultation with the appropriate subcode official(s), as one or more of six categories:  repair, renovation, alteration, reconstruction, change of use, and additions.  Specific requirements are established for each work category.

3.                  Work of more than one category may be part of a single work project.

3.Where a project includes repair, renovation or alteration work, then the work in each such category shall comply with the requirements for that category of work.

i.                     Where a project is a reconstruction project, which includes repair, renovation or alteration work, then the work in each such category, shall comply with the requirements for that category of work.

ii.                   Where an alteration project results in a new building element, then each such new element shall comply with the requirements for new building elements.

iii.                  Where a project is a reconstruction project, then the entire work area shall comply with the basic requirements of this subcode.  Where a reconstruction project in a building involves more than one work area, then each work area shall comply with the requirements of this subcode.  Additionally, reconstruction projects shall comply with the supplemental requirements of this subcode where they exceed the size requirements of this subcode where they exceed the size requirements specified by this subcode in the sections governing supplemental requirements.

iv.                 Where the use of a building or portion thereof is changed, then the building or portion thereof shall be made to conform to the requirements of this subcode for a change of use.  Where work is required by Section 7-3.31 of this subcode for a change of use to be approved, then that work shall comply with the requirements of this subcode for changes of use.  Where a project undertaken in connection with a change of use involves repairs, renovations or alterations, which are not required by this subcode for the change of use, then the work in each such category, shall comply with the requirements of this subcode for that category.

v.                   Where the work project involves an addition to a building, then the addition shall comply with the requirements of the other subcodes of the BOCA Building Code for new buildings.  Any repair, renovation or alteration undertaken in an existing building in connection with an addition shall comply with the requirements of this subcode for such category of work.

(c)                Compliance:  The only requirements of the other subcodes of the BOCA Building Code, which apply, are specifically set forth in this subchapter.  Compliance with the requirements of the other subcodes of the BOCA Building code is not required for work in existing buildings.  However, building components already in compliance with the requirements of the other subcodes of the BOCA Building Code shall be replaced with components that apply.  Where no year or edition is given for a standard referenced in this subchapter, the year or edition shall be the one referenced in the other subcode(s) of the BOCA Building Code.

1.                  Buildings in compliance with the current edition of the applicable subcode shall not be required to comply with any more restrictive requirement of this subcode.

2.                  The repairs, renovations, alterations, reconstruction, and changes of use and/or additions, of any building or structure currently existing shall conform to the requirements of this subchapter.  Where compliance with the provisions of this subchapter would result in practical difficulty, the owner may apply for a variation in accordance with the Sec. 121 BOCA.

3.                  Any variation previously issued in writing pursuant to the BOCA/ Code shall remain in force and effect unless the work to be performed during the course of the rehabilitation project causes one of the conditions of the variation to be violated or would otherwise create a hazardous condition.

4.                  As an alternative to compliance with the building and fire protection requirements of this subchapter, a permit applicant shall be allowed to evaluate the building in accordance with Section 3408.6 of the BOCA National Building Code, 1996 edition, incorporated herein by reference, and to bring the building into compliance with the standards contained therein.

(d)                Permits

(d)The requirements of this subchapter shall apply to all rehabilitation work without regard to whether a permit is required for such work.  It should not be assumed that a permit is required simply because a requirement is established by the subchapter.  Determinations as to whether a permit is required shall be made in accordance with the administrative provisions of the Sec. 107.1 contained in BOCA/ 1996 or other adopted Ordinance of the City of Shawnee.

(e)                Enforcement Responsibilities:  Responsibility for the enforcement of the provisions of this subchapter shall be as indicated in parentheses at the end of each section. For provisions of other subcodes of the BOCA Building Code referenced herein, enforcement responsibility shall be as indicated by Ordinance.

1.                  Assignment of enforcement responsibility for a requirement does not imply that work undertaken that would not otherwise require a permit required or a compliant lodged, the designated subcode official is responsible.  The parenthetical notes shall have the following meanings:

i.                     “Building” means that responsibility is assigned to the Chief Building/ Code official.

ii.                   “Fire” means that responsibility is assigned to the fire protection subcode official.

iii.                  “Electrical” means that responsibility is assigned to the Chief Electrical Inspector.

iv.                 “Plumbing” means that responsibility is assigned to the plumbing Chief Plumbing Inspector.

v.                   “Elevator” means that responsibility is assigned to the Chief Building/ Code official.

2.                  Responsibility for the enforcement of mechanical requirements in building of Use Group R-3 or R-4 may be assigned as delineated in NFPC/ 1996 at the discretion of the construction official.

3.                  Enforcement of the provisions of the barrier free subcode shall be as provided in Subchapter 11 of the BOCA/ 1996 Building Code.

(f)                 Pre-Existing Buildings

(f)Buildings or structures legally in existence at the time of the adoption or subsequent amendment of this subchapter may continue in use and nothing herein shall be interpreted as requiring the repaired, renovation, alteration or reconstruction of such building, except as provided at Sec. 119 BOCA/ 1996, Unsafe Structures.

(g)                Relationship of this Subcode to Other Codes, Rules, and Ordinances

1.                  It is the intent of this subcode to provide a uniform, harmonious system of rehabilitation regulations applicable to all existing buildings and structures in the City of Shawnee.  No code, ordinance, rule, regulation thereof, shall establish any requirement for any matter covered by this subcode.

2.                  It is the intent of the subcode to establish requirements for reconstruction projects which are at least as stringent as the requirements applicable to that area under the adopted Fire Code, the Regulations for Maintenance of Hotels and Multiple Dwellings and the Oklahoma State Housing Code.  This subcode shall not be interpreted as establishing requirements less stringent than these codes.

3.                  Certificates of occupancy issued for projects in compliance with the requirements of this subcode are specific to the work undertaken and shall not obviate the need for the building to be brought into compliance with the requirements of the Shawnee Fire Prevention Code.

i.                     Notwithstanding the above, a variation issued in writing pursuant to Sec.106.2 BOCA/ 1996 in connection with a rehabilitation project shall remain in force and effect provided that all of the conditions of variation continue to be met and shall be accepted for purposes of establishing compliance with Subchapter 4 of the Uniform Fire Code for the portion of the building to which the variation applies.

4.                  This subcode is not intended to establish minimum standards of habitability for housing.  No provision of any state or municipal housing code or the equivalent which establishes minimum standards for natural light, natural ventilation, minimum habitable floor area per occupant, or requirements for heat shall be deemed to be affected or superseded by this subchapter.

5.                  Where work is proposed to an existing commercial farm building or where the use of a building is changed to a commercial farm building, the building shall be permitted to comply with the requirements of this subchapter applicable to Use Group S-2.

6.                  The repair, renovation, alteration, reconstruction or change of use of health care facilities shall be in accordance with this code and with the “Guidelines for Construction and Equipment of Hospital and Medical Facilities,” 1992-93 edition or current edition (American Institute of Architects Committee on Architecture for Health). In the event of any conflict, the more restrictive code provision shall govern.

(h)                Correction of Violations of Other Codes

Alterations or renovations mandated by any property, housing, or fire safety maintenance 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 subchapter unless the code requiring such alterations so provides.

(i)                  Variations

Building owners wishing to use an alternative to compliance with specific provisions of this subcode shall submit request(s) for variations in writing in accordance with Article II Sec.10-20 of the Shawnee Fire Prevention Code For variation requests involving fire safety, the construction official shall consult with the fire official.  Then the approval of the fire official shall be required on such variation requests.

(j)                 Asbestos hazard abatement projects and lead hazard abatement projects shall not be categorized as reconstruction projects in and of themselves despite the fact that occupancy of the work area is not permitted.  However, all related construction work undertaken in connection with such projects and all replacement materials used shall comply with the applicable provisions of this subcode.

3 – Definitions

The words and terms used in this subcode shall have the following meanings unless the context clearly indicates otherwise.  Any term not defined herein, which is defined in any of the other subcodes of the BOCA Building Code, shall have the meaning as defined in that subcode.  Where a term is defined in this subcode and is also defined in another subcode, then the term shall have the meaning as defined herein wherever it is used in this subcode.

“Addition” means an increase in the footprint area of a building or an increase in the height and the number of stories of a building.

“Alteration” see definition under “Rehabilitation.”
