International Existing Buildings Code (IEBC) & Comm 66 Fundamentals & Revisions
2 Encourage the use and re-use of existing buildings while requiring reasonable upgrades and improvements in code compliance. IEBC Background
3 WI IEBC History Replaces S&B Existing Building Guidelines, Wisconsin Historic Code (Comm ch. 70) and IBC ch. 34, which share similarities with IEBC. Provides a more predictable alternative than one or more petitions for variance Note that there is no distinction between buildings originally approved under ICC suite or pre-ICC Wisconsin codes Note that per s , WI Stats, local ordinances may not be anymore restrictive for historic building projects approved per this code
4 IEBC Approach New work intended by the owner is generally regulated by the IBC, IMC, etc., but additional upgrades maybe triggered by the IEBC depending on the type and extent of the intended work.
5 IEBC Proportional Approach UPGRADESUPGRADES Alt. Lev.1Alt. Lev.2Alt. Lev Types of Work Ch. 6 Level 1 Alteration Ch. 7 Level 2 Alteration Ch. 8 Level 3 Alteration REQUIREDREQUIRED Change of Use Ch. 9 Change of Use
6 s. Comm (1) Application Does not apply to unchanged existing buildings which are instead subject to: Per s. Comm 61.03(13) for post-1914 structures: Buildings shall continue to comply with applicable State Building Code Bleachers and grandstands shall comply with ICC Bleacher Standard – annual owner inspections and retroactive 4 guard infills Or chs. Comm Buildings Constructed Prior to 1914 (previously titled, Existing Buildings Code) And applicable fire prevention codes, ch. Comm 14 & IFC or NFPA-1
ICC 300 Bleacher & Grandstand Standard Adopted per IBC 1028 Retroactive 4 bleacher guard infill at perimeter and between seats and footboards
8 s. Comm (2) Change of Use to a Public Building Change of Occupancy to a Public Building Occupancy from non-commercial use – comply with new construction requirements per IBC, rather than IEBC, except that archaic materials may continue to be used Revised Comm (2)(b)2. to allow qualified historic buildings including 1&2 family dwellings to use the IEBC May petition to use IEBC or alternative compliance for other non-commercial buildings Also requires that initial tenant spaces plans following shell approval shall meet new construction requirements of IBC
9 s. Comm Plan Submittal Required for new buildings, additions and alterationsRequired for new buildings, additions and alterations Change of Use - There is NO requirement that a plan has to be submitted to gain an approval for a change in use. Submittal requirements exist only for the plans of the alteration work that is often desired or required with a change a use.Change of Use - There is NO requirement that a plan has to be submitted to gain an approval for a change in use. Submittal requirements exist only for the plans of the alteration work that is often desired or required with a change a use (4) Minor AlterationsIf the code official can understand the proposed project and agree that compliance can be achieved without having plans to work from, no submittal of plans is necessary - Document the decision!61.30(4) Minor Alterations - If the code official can understand the proposed project and agree that compliance can be achieved without having plans to work from, no submittal of plans is necessary - Document the decision!

11 s. Comm (4) Compliance Methods Elect to use for alterations and changes of use: IEBC chs. 4-12, as appropriate Or IEBC ch. 13 for those topics covered, use IEBC for rest Or could also use current IBC, IMC, IFGC, etal. – in any case, dont have to do more than what the prevailing codes would require
12 IEBC ch. 2 Definitions Alteration – Further defined in IEBC ch. 4 Dangerous, Substantial Damage, Substantial Structural Damage and Unsafe Buildings – ch. 66 Deleted and , although code official may still require analysis Historic Building – WI amendment to be a qualified historic building per s. Comm 61.04(5) Primary Function – alterations to this triggers additional accessibility improvements Repair – maintenance, limited in scope, not overall alterations Technically Infeasible – for accessibility purposes, same as before Work Area – reconfigured space for purposes of level 2 or 3 alterations
13 Prescriptive Compliance Method Prescriptive Compliance Method Chapter 3 - Not applicable in WI Determined to be overly subjective Chapter 3
14 IEBC ch. 4 Classification of Work Chapter 4 Repair Alteration-Level 1 Alteration-Level 2 Alteration-Level 3 Addition Change of occupancy Relocated or moved buildings Historic buildings More than one classification can apply to a project
15 IEBC s Work area shall be shown on plans – note that per IEBC ch. 2 definition, work area means reconfigured space (not all alterations) –usually obvious Submitter states level of alteration (I, II or III) at time of scheduling and submittal
16 IEBC Chapter 5 - Repairs
17 IEBC Ch. 5 Repairs Repair or maintenance work is to a building, which encloses some space, not the rebuilding of total burnouts or collapses Code at original time of installation applies unless IEBC ch 5 requires upgrade No plan submittal to state unless locally required to document work
18 Revised – Carbon Monoxide Alarms for Smaller Existing CBRFs Retroactive requirement for existing CBRFs serving 9-20 residents to install carbon monoxide alarms similar to Comm requirements Deadline of January 1, 2013
19 Repairs IEBC & Permitted Materials Options Materials applicable for new construction per IBC, IMC, etc Like materials permitted provided no increased hazard to life, health or property is created.
20 Repairs IEBC Hazardous Materials Hazardous materials no longer permitted to be used in a repair –Asbestos, –Lead based paint, –Etc.
21 Repairs IEBC Glazing in Hazardous Locations Replacement of broken glazing in hazardous locations to comply with the applicable requirements of IBC ch 24 –Exceptions: glass block walls, louvered windows, and jalousies repaired with like materials. –(Note that most wired glass is not allowed for replacement in doors and sidelights)
22 IEBC Chapter 6 - Level 1 Alteration General removal and replacement of various materials regardless of need for maintenance or repair No area limitations in order to be considered a Level 1 Alteration Current IBC, IMC, etc. or IEBC ch. 6 applies, including to any new work. May or may not require plan submittal depending on work and code officials determination
23 Revised Comm – Smoke Alarm Maintenance Require replacement of smoke alarms per their listing Replacement battery- powered smoke alarms shall have a 10-year, non- replaceable, non- removable battery
24 Level 1 Alterations IEBC 605 Accessibility Alterations must meet new construction requirements, with exceptions. If the alterations include a primary function area, an accessible route, including sanitary facilities, to the area may be required as well.
25 s. Comm Note re WI Fair Housing Law The requirements of s , Stats., may be more restrictive than the IEBC when a project involves the remodeling of housing with three or more unitsThe requirements of s , Stats., may be more restrictive than the IEBC when a project involves the remodeling of housing with three or more units 4 Basic Requirements:4 Basic Requirements: 1.An accessible entrance 2.Accessible public/common use areas 3.Accessible doors & int. passage 4.Accessible features like accessible controls, grab bar reinforcement & lever handles
26 Fair Housing Law Remodeling Scenarios 1.> 50% of the interior square footage of the housing is remodeled, the entire housing shall conform to the standards 2.If 25% to 50% is remodeled, that part of the housing that is remodeled shall conform to the standards 3.If < 25% is remodeled, the remodeling is not subject to the standards unless the alteration involves work on doors, entrances, exits or toilet rooms, in which case those elements shall conform to the standards Disproportionality may limit expense to 20% of the projectDisproportionality may limit expense to 20% of the project
27 Level 1 Alterations IEBC 605 Accessibility IEBC Accessibility Required unless Technically Infeasible –Alteration or removal of major structural member –Existing physical or site constraints: Property lines Set back requirements Fire lanes Means or egress issues
28 Level 1 Alterations IEBC Accessibility Other IEBC Exceptions 1.An accessible route not required unless altering a primary function area 2.Accessible means of egress not required 3.Type B dwelling units not required by IEBC but may be required per WI Fair Housing Law – see Comm If a privately owned residential unit was originally designed as an A Type Unit, the private owner of the unit may modify the unit to be a Type B Unit.
29 Level 1 Alterations IEBC Accessibility Sections through relax the new construction accessibility requirements that would otherwise apply to existing elements that are being altered.
30 Section Entrances...when altering an entrance and the building already has an accessible entrance on an accessible route, the altered entrance need not be made accessible unless called for by s (Alterations Affecting an Area Containing a Primary Function)

36 Section Jury boxes...access not required within defined area of jury or witness stand where ramp or lift poses a hazard or restricts egress.
37 Section &.9 Dwelling & Sleeping Units When altering residential units, the accessibility requirements only apply only to the quantity of the spaces being altered at that time.
38 Section Toilet Rooms...technical infeasibility will permit the unisex toilet room on the same floor in the same area...
39 Section Fitting Room technical infeasibility will permit one accessible room on same floor in same area permitted... When fitting rooms provided for separate sex, each to have access as well.... technical infeasibility will permit one accessible room on same floor in same area permitted... When fitting rooms provided for separate sex, each to have access as well.
40 Section Thresholds...3/4 maximum height with beveled edges.
41 Section Alterations Affecting Areas of Primary Function...access to or areas containing a primary function...that route shall be accessible. Exceptions... Disproportionate cost – up to 20% of project cost but no more than needed to achieve full accessibilityDisproportionate cost – up to 20% of project cost but no more than needed to achieve full accessibility Alterations solely to windows, hardware, controls, etc.Alterations solely to windows, hardware, controls, etc. Alterations solely to systems like mechanical, electrical, fire protection, etc. or to mitigate hazardsAlterations solely to systems like mechanical, electrical, fire protection, etc. or to mitigate hazards Alterations to increase accessibilityAlterations to increase accessibility
42 Accessibility Primary Function Area Examples Customer services lobby of a bank Dining area of a cafeteria Meeting rooms in a conference center Offices and other work areas in which the activities of the facility are carried out

51 Work Area % Determination % Work Area = W/(A1+A2) x 100 Firewall Work Area with New Partitions (Area W) Building Area A1Building Area B1 Firewall Building Area A2 Building Area B2 1 st Story 2 nd Story
52 Level 2 Alterations Section 703 Building Elements & Materials Ch. 7 Approach - Additional limited improvements to systems such as vertical openings, fire protection systems, structural system and means of egress are triggered. Compliance with both Chapters 6 and 7 is applicable –Triggers based on specific thresholds –Sometimes only in work areas (reconfigured areas) –Supplemental requirements where work area on a floor exceeds 50%
53 Level 2 Alterations Section 703 cont. Stair Enclosures – Existing openings connecting 2 or more floor levels shall be enclosed with 1 hour fire rated construction within the work area Many exceptions apply (14) Exception 2 – Can use blocking for mechanical chases Exceptions 4-14 are for specific occupancies groups – may go down to 30 min. enclosures < 3 stories Per one cant make situation less safe than IBC.
54 Level 2 Alterations Section Supplemental shaft and floor opening enclosure requirements –Where the work area on any floor exceeds 50% of that floor area, the enclosure requirements of Section shall apply to vertical openings other than stairways throughout the floor. Exception – Vertical openings located in tenant spaces that are entirely outside the work area
55 Level 2 Alterations Section Supplemental stairway enclosure requirements –Where the work area > 50% of that floors area, stairways that are part of the means of egress serving the work area shall, at a minimum, be enclosed with smoke-tight construction on the highest work area floor and all floors below.
56 Level 2 Alterations Section Sprinklers Sprinkler requirements for –High-rise buildings –Listed occupancies –Windowless stories But not applicable unless the building has sufficient municipal water supply for design of a fire sprinkler system available to the floor without installation of a new fire pump WI amendment allows omission of sprinklering in inaccessible existing cavities
57 Level 2 Alterations Section Other Fire Protection Requirements Standpipes- Required where the work area includes exits or corridors shared by more than one tenant and is located more than 50 ft above or below the lowest level of fire department. See exceptions. Fire Alarms – In work areas. See occupancy requirements of and the IFC
58 Level 2 Alterations Section 705 Means of Egress Note that per IEBC 705.1, this whole section only applies where egress is shared by multiple tenants in the work area Topics –Number of exits –Fire Escapes, including new ones –Doors –Corridor Openings –Dead End Corridors –Means of Egress Lighting –Exit Signs –Handrails
59 Level 2 Alteration Section 706 Accessibility IEBC – If a new stair or escalator is installed, then analyze the served levels for vertical accessibility per new construction standards May apply disproportionality
60 Chapter 8 Level 3 Alterations Description (IEBC 405.1) –Alterations where the work area is > 50% of the aggregate area of the building –Comply with IEBC chs. 6, 7 & 8 –IEBC modifies IEBC 705 Means of Egress to apply to single tenant spaces too
61 Level 3 Alterations IEBC Shafts IEBC From the highest work area floor, regardless of % work area on that floor, enclose, per IEBC , all existing stairways that are part of the means of egress down to the level of exit discharge :
62 Level 3 Alterations Section Sprinklers in High Rise Buildings (>75) w here the building has sufficient municipal water supply system to the site –In work areas –And where the work area > 50% of the area on a floor that has corridors which are shared or serve > 30 persons, then throughout the floor except in tenant spaces totally outside the work area
63 Level 3 Alterations Section – Fire Alarms Required per IEBC throughout the building, with exceptions
64 Comm Potty Parity Level 3 alterations where the public congregates requires 2x plumbing fixtures for females vs. males Where the public congregates: >500 persons at an amusement facility, convention center, sports arena, recreation center, stadium, airport or depot
65 IEBC Chapter 9 – Change of Occupancy
66 Change of Occupancy IEBC Chapter 9 applies where: –There is a change in purpose or level of activity within a building, –There is a change in occupancy group (from one group use to another), or –There is a change of occupancy classification (from one classification within the same Group to another classification in the Group i.e. A-3 to A-2) –Look at actual current use (or last use, if currently vacant), not previous broad approval –Remember <10% accessory use design option
67 Change of Occupancy IEBC Where there is an increase in occupant load but no change in occupancy classification, just apply: –IEBC 907 – Structural –IEBC 908 – Electrical –IEBC 909 – HVAC –IEBC 910 – Plumbing –Any applicable alteration chapter(s). (Other Ch 9 sections are scoped to changes in occupancy classification)
68 Change of Occupancy IEBC Where the occupancy classification of a building changes, provisions of sections 902 thru 912 are applicable. IEBC requires compliance with chs. IEBC 8, 7 & 6, per the scoping of the sections in those chapters, e.g. in work areas.
69 Change of Occupancy IEBC 901 Comm (2) Buildings undergoing a change of occupancy that would result in an increase in demand for fossil fuel or electrical energy shall comply with IECC.
70 Change of Occupancy IEBC 902 Special Use & Occupancy Where the use of an existing building is changed to one of the following occupancies the building shall comply with all applicable requirements of the IBC: 1.Covered mall buildings, 2.Atriums, 3.Motor-related occupancies, 4.Air-craft related occupancies, 5.Motion picture projection rooms, 6.Stages and platforms, 7.Special amusement buildings, 8.Incidental use areas, 9.Hazardous materials.
71 Change of Occupancy s. Comm Toilets Allows up to a 20% increase in occupant load in a story before additional sanitary fixtures are required
72 Change of Occupancy IEBC 911 Other Requirements IEBC 911 Light & ventilation shall comply with the requirements of IBC for the new occupancy Comm At least one existing elevator shall be provided with emergency recall operation and emergency in-car operation complying with Comm 18 when an existing building or structure greater than 60 feet is changed to a Group R-1 or R-2 occupancy.
73 Change of Occupancy IEBC Change of Occupancy Classification Without Separation If new occupancy is not separated from the remainder of the building with fire barriers per IBC , the entire building shall comply with all requirements of IEBC chapter 8 (Level 3 Alterations) applied throughout the entire building for the most restrictive occupancy classification in the building (Not applicable to Ch 9 requirements)
74 Change of Occupancy IEBC Fire Protection & Interior Finish Provisions of sections & for fire sprinklers, alarms and and interior finish apply to all buildings undergoing a change of occupancy classification. –Sprinkler thresholds area based on whether fire barriers are provided per IBC T –But install in the actual physical area of the change
75 Change of Occupancy Hazard Categorization Hazard comparisons and code applications for: –IEBC Means of Egress –IEBC Heights & Areas –IEBC Exposure of Exterior Walls
76 Typical Hazard Comparison Table:
77 IEBC Means of Egress Where the means of egress for change of use is to a higher hazard occupancy classification then the means of egress shall comply with the requirements of chapter 10 of the IBC. Exceptions: –Stairways can instead be enclosed in accordance with the applicable requirements of IEBC section –Existing stairways including handrails and guards complying with IEBC chapter 8 are permitted for continued use subject to approval of the code official –Stairways replacing existing where the slope cannot be reduced because of existing construction are not required to comply with riser height or tread depths of IBC
78 IEBC Means of Egress Where the means of egress for change of use is to an equal or lower hazard occupancy classification then the means of egress shall comply with the requirements of IEBC section 805 for the new occupancy classification. Newly constructed or configured means of egress shall comply with the requirements of chapter 10 of the IBC. Exception: –Stairways replacing existing where the slope cannot be reduced because of existing construction are not required to comply with riser height or tread depths of IBC.
79 IEBC Means of Egress – Any Change of Occupancy Class Egress capacity shall meet or exceed the occupant load as specified in the IBC for the new occupancy Existing stairways shall comply with handrail requirements of IEBC section in the area of change of occupancy classification Existing guards shall comply with requirements of IEBC section in the area of change of occupancy classification.
80 Change of Use IEBC Enclosure of Vertical Shafts If change of occupancy to a higher hazard per IEBC for Means of Egress, then generally enclose per IBC with some exceptions
81 Change of Use IEBC Accessibility Existing buildings or portions thereof that undergo a change of Group or occupancy classification shall have all of the following accessible features: 1.At least one accessible entrance 2.At least one accessible route from an accessible building entrance to primary function areas 3.Signage complying with IBC section Accessible parking when parking is provided 5.At least one accessible loading zone when loading zones are provided 6.An accessible route connecting accessible parking and loading zones to the accessible building entrance (Does not include toilets) Revised 2009 IBC amendment to only require the above if the whole building changes occupancy type.
82 Change of Use IEBC Accessibility When it is technically infeasible to comply with the new construction standards for any of the previous six requirements for a change of Group or occupancy, the items shall comply with the requirements to the maximum technically feasible. Exception for 20% disproportionality also allowed.
83 Change of Use IEBC Accessibility Exception: EXCEPTION STATES: Type B dwelling or sleeping units required by section 1107 of the IBC are not required to be provided in existing buildings and facilities. Note: If there is a change of occupancy from say R-1 to R-2, this exception to not provide type B dwelling units would stand. If remodeling accompanies the change of occupancy then the IEBC chs. 6-8 applies, as well as the statutory provisions for remodeling, and some type B units may then be required.
84 IEBC Chapter 10 - Additions
85 An addition is defined as the extension or increase in the floor area (including mezzanines), number of stories or height of a building additions to a building shall comply with the IBC for new construction Where an addition impacts the existing building that portion shall comply with the requirements of IEBC. An addition shall not create or extend any nonconformity in the existing building, as may occur without a firewall separation Additions IEBC General
86 Additions IEBC Height & Area Infilling of floor openings and creation of non- occupiable appendages such as elevator and stair shafts are not considered additions
87 Un-separated Addition Consider the greater building height and combine the fire and building areas of the new and old if no firewall or fire barrier Consider the greater building height and combine the building areas of the new and old if only a fire barrier EssiEssi Existing Addition
88 Separated Addition Even with a firewall separation, the addition may create a non-compliance in the existing building, which is prohibited by IEBC
89 Additions Pre-IBC Unlimited Area Building With Firewall Separation from an Addition Existing limited area or pre-IBC unlimited area building Addition Fire wall Addition removes one street exposure that was required by previous code requirement so street on right side of existing building must be provided on top side of building or current area requirements for existing building must be complied with.
90 Additions IBC CODE Unlimited Area Building With Addition Existing unlimited area building Addition Addition will have to be provided with a 60 ft clear space all around building or petition for variance on existing building needs to be submitted or existing building needs to comply with limited area requirements of IBC. 60
91 Additions IEBC 1002 Heights & Areas If no firewall or fire barrier provided: –Check combined height and area per IBC Ch.5 – existing fire areas increased by the addition shall comply with chapter 9 of the IBC. Exception for area created by in-filling of floor openings and non-occupiable appendages such as elevator and exit stair shafts.
92 Revised Comm – Sprinklering of Townhouse Additions If the townhouse does not have sprinklers, an addition to an existing dwelling unit will not trigger sprinklers to be installed
93 Additions IEBC 1003 Structural Analysis of Existing Building Gravity loads Wind loads Snow loads Flood load
94 Additions IEBC 1004 Smoke Alarms in Groups R-3 & R when an addition is made to a building of a Group R-3 or R-4 occupancy, the existing building shall be provided with smoke alarms as required by the IBC. If the addition is separated from the existing building by a fire wall then compliance with this section of the code is not required.
95 Additions IEBC 1005 Accessibility accessibility provisions for new construction shall apply to additions. Additions that affects the accessibility to, or contains an area of primary function shall comply with the requirements of section 605.
96 IEBC 11 Historic Buildings Any building that is: Listed or nominated to be on the national register of historic buildings by the state historical society. Included in a district which is listed on, or has been nominated by state historical society for listing on, the national register of historic places in Wisconsin, & has been determined by the state historical society to contribute to the historical significance of the district. Listed on a certified municipal register of historic property Included in a district which is listed on a certified municipal register of historic property, and has been determined by the municipality to contribute to the historic significance of the district.
97 Historic Buildings IEBC 11 Purpose Liberalizes the IEBC requirements in order to preserve the historic fabric of the building IEBC chapter 11 works with other chapters per IEBC notation.
98 Historic Buildings Museums Museums < 3000 sf & Group R-3 also used for A, B or M occupancy shall be viewed as Group B. Can limit the occupant load of museums or require supervision (such as a tour guide).
99 Historic Buildings Relocations New foundation meets IBC Location on site meets IBC Remainder of building considered historic & meets IEBC chapter 11
100 Historic Buildings Replacements Replacement of existing or missing pieces may be: –With either original materials. –Partial replacements for repairs that matches the original in configuration, height, and size. Except safety glazing shall be per current code
101 Historic Buildings Scope Historic buildings shall comply with IEBC 1103 if they are undergoing: –Alterations –Change of occupancy –That are moved (unless use ch. 12)
102 Historic Buildings Accessibility Accessibility alterations must meet IEBC 605, unless technically infeasible. Where the accessible requirements would threaten or destroy historic significance, code official may allow alternatives.
103 Historic Buildings Accessibility At least one main entrance accessible. Accessible route from accessible entrance to public spaces on the level of entrance. If main entrance is not made accessible, then provide either an accessible unlocked nonpublic entrance or remote notification serving accessible locked entrance. Accessible toilets or unisex toilet room.
104 Historic Buildings Change of Occupancy Follow IEBC chapter 9, except where specifically mentioned in to provisions.
105 Historic Buildings (2) Exhibit Buildings Special limitations for historic buildings which are used as exhibit buildings are provided with nine special items that must be met. Some of these are similar to museum limits in IEBC requirement.
106 Historic Buildings Structural Alternative code official judgment may accept existing floors or use limits. Unsafe elements, components or a portion of the building determined by the code official as dangerous, thus shall be repaired, strengthened or replaced.
107 IEBC Chapter 12 – Relocated or Moved Buildings
108 Relocated Buildings IEBC 1201 General Not applicable to re-used building materials – the building must be moved as a whole or sections that enclose space to be considered a moved building Any repair, alteration, or change of occupancy within the moved structure shall comply with the requirements of this code applicable to the work being performed
109 Relocated Buildings IEBC 1202 Site Requirements building shall be located on lot in accordance with requirements of IBC foundations system of relocated buildings shall comply with requirements of IBC
110 Relocated Buildings IEBC 1202 Structural Requirements buildings shall comply with IBC wind load provisions as applicable. Exception: structural elements whose stress is not increased by more than 5% buildings shall comply with IBC for seismic provisions as applicable. Exceptions: structures in design category A & B where the seismic loads at the new location are not higher than those at the previous location, & structural elements whose stress is not increased by more than 5%
111 Relocated Buildings IEBC 1202 Structural Requirements cont structures shall comply with IBC snow load provisions where snow loads at new location are higher than those at previous location. Exception: structural elements whose stress is not increased by more than 5%.
112 IEBC 13 Performance Compliance Method
113 Performance Compliance Methods Scope Scope of chapter 13 permits the existing building to comply with this chapter for covered topics, instead of complying with chapters 4 to 12. Point system – similar to previous ch. Comm 70 – alternative to numerous petitions
114 Performance Compliance Methods (1) Eligible Use Groups Methods of IEBC to are available for occupancy groups A, B, E, F, M, R & S. Groups H & I cannot use IEBC chapter 13.
115 Performance Compliance Methods Partial Use Change Partial change in occupancy options: 1)If separated by fire barrier, then only portion changed shall be made to conform to the provisions of this section. 2)If unseparated by fire separation to IBC Table , then whole building must comply. If conflict, use more strict.
116 Performance Compliance Methods Additions Additions shall comply to the IBC & IEBC for new construction. Existing plus addition height & area shall meet limitations of IBC chapter 5. Fire walls shall permit the addition to be regulated as a normal separated building.
117 Performance Compliance Methods Comm 1301(2) - Accessibility Accessibility per IEBC 310 is required for all portions of the buildings proposed for change of occupancy or alteration
118 Performance Compliance Methods Structural Investigation & evaluation via: Structural analysis to IBC Submittal of results and analysis Code official determines compliance using evaluation process of sections to
119 Performance Compliance Methods Evaluation Criteria Evaluation is comprised of 3 categories: 1) Fire safety 2) Means of egress 3) General safety
120 Performance Compliance Methods Evaluation No separation – evaluate each occupancy and apply the lowest score to the whole building. With occupancy separation – evaluation of each portion of the building is separate for that occupancy. Each separated part will then have a separate score evaluated.
