101.2 - Scope 101.2 - Scope The IEBC covers all aspects of existing

buildings including maintenance, repairs, alterations, additions, change in use, historic buildings and relocation.




101.3 – Intent 101.3 – Intent Alternative approaches (regulations) Application of any enforcement-oriented

interpretive action or judgment. Code official needs to be able to review,

evaluate and rule on performance designs


101.4 – Applicability 101.4 – Applicability Can a building take advantage of the more

relaxed provisions of the IEBC before construction of the building has begun?

At the time a building was constructed, there was no law or ordinance requiring compliance with an established set of codes or standards, permits or inspections within the jurisdiction: Would the building be considered legally occupied?


101.7 – Correction of Violations of Other Codes 101.7 – Correction of Violations of Other Codes Repairs or alterations compliant with other

adopted maintenance codes, International Property

Maintenance Code® (IPMC®) International Fire Code® (IFC®),

Are not required to comply with the IEBC unless those codes so provide.


Language was revised and added to clarify how to deal with conflicts with referenced standards and understanding how the scoping of similar subjects by this code and standard are addressed.


102.4—Referenced Codes and Standards102.4—Referenced Codes and Standards

Workbook Page 9



This clarification is particularly important when this code and the standard have similar scopes. This clarification of what provisions take precedence is intended to reflect consistency with other I-codes.



Workbook Page 9

Note: this essentially added a new section 102.4.1 and 102.4.2. Section 102.4.1 was based upon existing language and Section 102.4.2 which addresses similar scopes is all new language.

DefinitionsDefinitionsChapter 2:


Rewording of the definition is intended to correct awkward grammar and sentence structure and to place the emphasis of “necessary” directly on “support.” (See below)


Section 202—DangerousSection 202—Dangerous



In this code, lateral system upgrades are triggered where lateral system damage from any cause is classified as Substantial Structural Damage (SSD). The change from 20 percent to 33 percent of the lateral-load capacity redefined the SSD to what is considered a more reasonable threshold to require an upgrade of a damaged building. (See below)

Module 2Chapter 3:


Section 101.5, which included the basic procedural provisions of this code, as well as specific seismic evaluation and design criteria, did not belong in Chapter 1. The movement of Sections 101.5 through

101.5.4 to Chapter 3 in the 2012 edition remedies the situation of having technical criteria in the administration chapter.

Module 3Chapter 4:


This Section provides guidance to engineers when selecting system-related design coefficients for existing seismic force systems.


401.2.3—Existing Seismic-Force-Resisting Systems401.2.3—Existing Seismic-Force-Resisting Systems

Previously, this guidance was located within each individual section related to alterations, additions, repairs and changes of occupancy but has been relocated to a more general section to ensure consistent application.

The intent is that existing systems should be considered “ordinary” by default.

For seismic systems that may provide performance equivalent to that of a detailed, intermediate, or special system, this code requires a demonstration of equivalence






This only applies to systems for which there is a choice of “ordinary,” “detailed,” "intermediate" or “special” for the permitted seismic force systems.


For example, light-frame shear walls are not categorized as ordinary, detailed, intermediate or special. Those systems are acceptable, and the system coefficients specified for those systems in ASCE 7 are appropriate.

The relocation is related to the need to emphasize the broad applicability of this provision throughout Chapter 4 and it is not simply limited to repairs.


401.3—Dangerous Conditions401.3—Dangerous Conditions This revision relocates a provision related to the ability of

the building official to address dangerous conditions from Section 304.1.1 (Section 304, Repairs) to Section 401.3 (Section 401, General).

402.3 - Existing structural elements carrying gravity load 402.3 - Existing structural elements carrying gravity load Where additions and related alterations increase

the force in any existing structural element by more than 5 percent, the structural elements must be altered and replaced to carry the increased load as required for new construction.


402.4 - Existing structural elements carrying lateral load 402.4 - Existing structural elements carrying lateral load There are three options for seismically designing

an addition to an existing structure: Design the addition as being structurally independent

from the existing building: The addition must be designed to meet the requirements for new construction.

Design the addition as not being structurally independent from the existing building: The addition and existing structure must be designed to meet the requirements for new construction.




402.4 - Existing structural elements carrying lateral load 402.4 - Existing structural elements carrying lateral load There are three options for seismically designing

an addition to an existing structure: Design the addition as not being structurally

independent from the existing building: The addition must be designed to meet the requirements for new construction and the addition must not increase the demand-demand-capacity ratio of any existing lateral load-carrying element by more than 10 percent.


402.5—Smoke Alarms in Existing Portions of a Building 402.5—Smoke Alarms in Existing Portions of a Building This provision was added since Chapter

34 of the International Building Code®

(IBC®) did not currently provide a path to the International Fire Code® (IFC®)for the smoke alarm requirements in existing buildings. This new section connects this code

directly to Section 1103.8 of the IFC.


402.5—Smoke Alarms in Existing Portions of a Building402.5—Smoke Alarms in Existing Portions of a Building The work area method (chapters 5 through

13) already addresses this link but as Chapter 4 is simply a duplication of Sections 3401 through 3411 of the IBC, this section is now located within Chapter 4, as well.


This new section is consistent with the addition of new Section 402.5, and with the need in IBC Chapter 34 for the link to the IFC for smoke alarm requirements in existing buildings.

This new section fixes a technical flaw between the IFC and this code by tying the requirements for smoke alarms in individual sleeping units and individual dwelling units in Group R and I-1 directly to the Section 1103.8 of the IFC.


403.6—Smoke Alarms403.6—Smoke Alarms

Workbook Page 21



403.6—Smoke Alarms 403.6—Smoke Alarms In the past, this code limited the level of

building fire protection by isolating such requirements to work areas only. The structure of the IFC is that the

retroactive requirements apply to all buildings, whether or not those buildings are undergoing alterations.


Basic repair—that is, restoring the pre-damage condition—is still required even for the exceptions outlined.


404.2—Substantial Structural Damage to Vertical Elements of the Lateral-Force-Resisting System


Two new exceptions that exempt certain combinations of buildings, seismic risk, and damage from triggered seismic upgrades, were added to Section 404.2.

Workbook Page 21

Exception 1,(New) The first exception is for

buildings in areas of low or moderate seismicity [Seismic Design Category (SDC) A, B or C], where the damage was not caused by an earthquake and therefore would not be required to be evaluated or rehabilitated for load combinations that include earthquake effects as in Section 404.2.




Workbook Page 21

Exception 1, (New) This exemption of Seismic

Design Category C is new with the 2012 edition. Where earthquakes are rare, it serves no significant public purposes to trigger seismic upgrades following damage caused by fire, collision, wind, etc.




Workbook Page 21



Exception 2, (New) The second exception is for one- and two-

family dwellings, where the public risk is especially low even though the damage may be associated with earthquake effects. Similar revisions were made to Chapter 6, Repairs.




Workbook Page 21

This section was revised to remove the list of SDC’s requiring evaluation that is now addressed by Section 404.2, Exception 1, which exempts SDC’s A through C.

Therefore, this section regulates SDC’s D through F.


404.2.1—Evaluation404.2.1—Evaluation

Workbook Page 21

Additionally, in correlation with the new requirement in Section 401.2.3, the provisions providing guidance to engineers on selecting system-related design coefficients for existing seismic force systems are no longer necessary in this location. In Section 401.2.3 there is a more general application to the entire chapter.


404.2.1—Evaluation404.2.1—Evaluation

Workbook Page 21

404.3 - Substantial structural damage to gravity load-carrying components 404.3 - Substantial structural damage to gravity load-carrying components

Substantial structural damage to gravity load-carrying elements must be repaired.

Snow loads must also be included where the substantial damage is associated with the effects of snow load.




Exceptions 1 and 2 (New) This section added two new exceptions which are

identical to Section 404.2. The reasoning for the exceptions is the same.

The primary differences between the two sections is that: Section 404.2 deals with the vertical elements of the

lateral-force-resisting system. Section 404.3.1 deals with damage caused by wind

and earthquake to the gravity load-carrying components in a building.

404.4 - Less than substantial structural damage 404.4 - Less than substantial structural damage Damage that is not deemed to be substantial

structural damage, repairs are allowed that restore the building to its pre-damaged state using materials and strengths that existed prior to the damage.

New structural members and connections used for this repair must comply with the detailing provisions for new buildings of similar materials, purpose and location.

407.1 – Conformance Change in Occupancy 407.1 – Conformance Change in Occupancy A change in occupancy to an existing building

requires the building to meet the requirements of the IBC for the new occupancy.




407.4 – Structural 407.4 – Structural When a change in occupancy results in the

structure being reclassified to a higher occupancy category, the seismic requirements for new construction apply to the existing structure.


408.1 - Historic buildings408.1 - Historic buildings Except for historic structures located in flood

hazard areas, a proposed change of occupancy that does not constitute a distinct life safety hazard may be approved by the code official.


408.2 - Flood hazard areas 408.2 - Flood hazard areas An historic building located in a flood hazard

area is required to comply with the flood provisions of the IBC unless one of the following is applicable: An historic building is listed in the National Register of

Historic Places; Determined by the U.S. Department of the Interior as

contributing to the historical significance of an historic district; or

Designated as historic under a program that is approved by the U.S. Department of the Interior.


Accessibility for Existing Buildings – 410 Accessibility for Existing Buildings – 410 The intent is that when a building is altered, it

should be made accessible to the maximum extent possible within reason.




The exception that exempted Type B units from being provided in existing buildings being altered or undergoing a change of occupancy was deleted.


410.1—Scope410.1—Scope

Workbook Page 23

This coordinates with a number of revisions that now require that Type B units be addressed when an alteration affecting over 50 percent of the building is being undertaken with or without a change of occupancy.


410.1—Scope410.1—Scope

Workbook Page 23

When a change of occupancy includes alterations to more than 50 percent of the building, Type B dwelling or sleeping units, as required by Section 1107 of the IBC, will be required in Group I and R facilities.


410.4— Change of Occupancy410.4— Change of Occupancy

Workbook Page 24

Exception (New) In accordance with the new exception,

when Type B units are required in existing buildings, the additional accessible features listed in Section 410.4.2, Items 1 through 6 are not required for an accessible route to Type B units.

410.5 – Additions410.5 – Additions Provisions for new

construction apply to additions . Note that if an addition affects accessibility to or contains an area of primary function Section 410.7 applies.


410.6 – Alterations410.6 – Alterations Alterations are required to

comply with the provisions of Chapter 11 of the IBC unless technically infeasible. Note that technically infeasible is a defined term.


410.7 - Alterations affecting an area of primary function410.7 - Alterations affecting an area of primary function The accessible route to that function and any

toilet rooms or drinking fountains serving it must be evaluated for accessibility.

A primary goal is that all buildings will become fully accessible over time.


Exception 5 (New) Where an alteration affects the

accessibility to, or contains an area of primary function, the route to the primary function area shall be accessible. Per the new exception, this provision

does not apply to altered areas limited to Type B dwelling and sleeping units.

410.8.2 – Elevators 410.8.2 – Elevators All elevators on an accessible

route must be fully accessible in accordance with ICC A117.1.

If a passenger elevator is altered, the altered element must be accessible in accordance with the existing elevator requirements in ICC A117.1 407.


410.8.3 - Platform lifts 410.8.3 - Platform lifts Given the choice between no accessibility or

accessibility by a platform lift, accessibility is preferable.


410.8.4 - Stairs and escalators 410.8.4 - Stairs and escalators Intent is that if a route is provided between

accessible levels for a nondisabled person to use, it is reasonable to also expect an accessible route.


Accessibility for Existing Building - 410Accessibility for Existing Building - 410 410.8.5 – Ramps 410.8.6 - Performance areas 410.8.7 - Dwelling or sleeping units




This section expands the application of the requirements of Section 1107 of the IBC for Type A units when more than 20 Group R-2 dwelling or sleeping units are added to also include units altered. These requirements apply only to the

quantity of the spaces being altered or added.


410.8.8—Type A Dwelling or Sleeping Units410.8.8—Type A Dwelling or Sleeping Units

Two new exceptions that exempt certain combinations of buildings, seismic risk, and damage from triggered seismic upgrades were added to Section 606.2.2.


606.2.2—Substantial Structural Damage to Vertical Elements of the Lateral-Force-Resisting System


Basic repair, that is, restoring the pre-damage condition, is still required even for the exceptions outlined.

Workbook Page 35

Exception 1 (New) The first exception is for buildings in areas of

low or moderate seismicity (SDC’s A, B or C), where the damage was not caused by an earthquake.

These buildings would not be required to be evaluated or rehabilitated for load combinations that include earthquake effects as in Section 606.2.2




Workbook Page 35

Exception 1 (New) Where earthquakes

are rare, it serves no significant public purposes to trigger seismic upgrades following damage caused by fire, collision, wind, etc.




Workbook Page 35



Exception 2 (New) The second exception is for one- and two-

family dwellings where the public risk is especially low even though the damage may be associated with earthquake effects. These are the same exceptions found in

the prescriptive compliance method in Section 404.2.

A fire has caused damage to a one story-building. Many walls, ceilings and doors must be replaced, including the walls and the doors of a corridor that were not fire-resistance rated, but would be required to be fire resistance rated under the IBC. The walls are not load bearing. Can the walls of the corridor be reconstructed, and the other doors be replaced with the same construction and door as before the fire?




Chapter 6 – Q&AChapter 6 – Q&A Can the walls of the corridor be

reconstructed, and the other doors be replaced with the same construction and door as before the fire?

109

No. The walls of the corridor would be considered an alteration, Level 2 because of

the reconfiguration of the corridor. The construction of the corridor would be

considered new construction; therefore, Section 801.3 would apply and must comply

with all of the requirements of the IBC. A permit would also be required.

706.3.1 - Bracing for unreinforced masonry bearing wall parapets 706.3.1 - Bracing for unreinforced masonry bearing wall parapets The failure of parapets in unreinforced masonry

(URM) bearing wall buildings has been a recurring problem in areas that experience significant earthquakes.

The code requires these elements to be braced where the seismic hazard is deemed to be relatively high and reroofing work is greater than 25% of the roof area.




706.3.2—Roof Diaphragms Resisting Wind Loads in High-Wind Regions706.3.2—Roof Diaphragms Resisting Wind Loads in High-Wind Regions In level 1 alterations, evaluation criteria for

wind resistance of roof diaphragms have been revised to clarify which parts of the roof connections need to be evaluated in accordance with the wind-load requirements of the IBC.


706.3.2—Roof Diaphragms Resisting Wind Loads in High-Wind Regions706.3.2—Roof Diaphragms Resisting Wind Loads in High-Wind Regions This section was also revised to allow

807.5—Existing Structural Elements Resisting Lateral Loads807.5—Existing Structural Elements Resisting Lateral Loads Rather than having Level 2 alterations

reference the provisions of Level 3 alterations (which are split into two classes, substantial and limited), the revisions move the relevant wind and seismic requirements into the Level 2 provisions.


There is one substantive change to Section 807.5, but it is actually a correction: The 2009 provision refers to Section 1613 of the IBC for seismic loads.

This is inconsistent with the provisions of this code for Level 3 alterations, therefore, the reduced IBC-level seismic forces are used in place of the reference to Section 1613 of the IBC.


807.5—Existing Structural Elements Resisting Lateral Loads807.5—Existing Structural Elements Resisting Lateral Loads

Workbook Page 50



Additionally, Section 807.5 also requires that the alteration not create a structural irregularity prohibited by ASCE 7, unless the entire structure complies with the reduced IBC level seismic forces.



Workbook Page 50

The creation of a new structural irregularity might not cause element demand-capacity ratios to increase by more than 10 percent, but those irregularities should still be avoided. Structural irregularities in existing

construction need not be eliminated.

elements whose demand-capacity ratio with the alteration considered is more than 10 percent greater than its demand-capacity ratio with the alteration ignored must undergo an engineering evaluation and analysis by a registered design professional, which must be submitted to the code official.




The revision included in Section 907.4.2 expands the time frame in which alterations are required to be counted together for purposes of determining whether the project is big enough to trigger a seismic upgrade from one year to five years.


907.4.2—Substantial Structural Alteration907.4.2—Substantial Structural Alteration

Workbook Page 58

907.4.2—Substantial Structural Alteration907.4.2—Substantial Structural Alteration

This proposal reduces the possibility that this code is applied such that the trigger is intentionally avoided. For example, by phasing alteration work over three

years, it is possible that a cumulative 89 percent of the floor and roof area could be altered in a nonconforming building, thus avoiding the intended upgrade trigger.

Five years was felt to be a period that is appropriate to the nature of seismic upgrades.


This Section correlates with the revisions to Section 807.5 in that Section 907.4.3 now simply references Section 807.5 for the relevant wind and seismic provisions. Also, rather than repeating the criteria for a

substantial structural alteration, simplified text is provided and substantial structural alteration is described in Section 907.4.2.


907.4.3—Limited Structural Alteration907.4.3—Limited Structural Alteration

907.4.3 - Limited structural Alteration907.4.3 - Limited structural Alteration A building undergoing limited alterations

(less than that required in Section 907.4.2) with a seismic base shear increase greater than 10 percent, needs comply with Section 807.5




This change relocates the triggered structural improvement of installation of wall anchors for concrete and masonry buildings from Alterations—Level 1 to Alterations—Level 3 where it is more appropriate.


907.4.4—Wall Anchors for Concrete and Masonry Buildings907.4.4—Wall Anchors for Concrete and Masonry Buildings

Workbook Page 59

Re-roofing does not make the anchor installation more convenient or cost-effective. In some cases, the Level 1 trigger could

result in disproportionate additional costs, discouraging the rather simple, but important, act of maintaining the roof. Therefore, this building improvement makes

more sense as a Level 3 Alteration.


907.4.4—Wall Anchors for Concrete and Masonry Buildings907.4.4—Wall Anchors for Concrete and Masonry Buildings

Workbook Page 59

This new section requires the installation of a parapet bracing in buildings undergoing a Level 3 alteration and assigned to Seismic Design Category D, E or F that have parapets constructed of unreinforced masonry whether or not reroofing is involved.


907.4.5—Bracing for Unreinforced Masonry Parapets (New)907.4.5—Bracing for Unreinforced Masonry Parapets (New)

This change is similar to the current requirements within Alteration—Level 1, Section 706.3.1, except that Section 706.3.1 is only required if a roofing permit is obtained and work exceeds 25 percent of the roof area.

Change of OccupancyChange of Occupancy

Module 9Chapter 10:


General - 1001 General - 1001 There are three basic types of change of

occupancy: One in which the occupancy classification

changes to a different group. One where the occupancy classification

changes within a group. One where the occupancy classification stays

the same but the level of activity changes.




General - 1001 General - 1001 Triggers in this chapter are predicated on a

change of occupancy to a higher hazard classification and a change in occupancy classification.

A change of use of a historic building must comply with Section 1205.


Special Use and Occupancy -1002Special Use and Occupancy -1002 This section

addresses ten special use and occupancy categories.

Any change to one of these occupancies would be required to comply with the provisions of the IBC.


There are new additional requirements for ambulatory care facilities in Section 422 of the IBC. This section adds ambulatory care

facilities to its list of special use or occupancy categories in which a change in character or use of an existing building requires compliance with the IBC.

This allowance does come with several required criteria: An NFPA 13 sprinkler system. Equivalent fire-resistance ratings in

accordance with fire wall ratings. A limitation on maximum allowable area that

does not allow an increase for an automatic sprinkler system.



Workbook Page 69



Exception: Where horizontal assemblies are used to limit the maximum allowable area, the required fire-resistance rating of the horizontal assemblies is permitted to be reduced by 1-hour reduction provided the sprinkler credit that would otherwise be given for the increase in height and number of stories currently allowed by Chapter 5 of the IBC has not been applied.

Historic BuildingsHistoric Buildings



When putting together a report for a historic building in SDC D, E, or F the engineer needs to include a structural evaluation requiring, at minimum, a description of the vertical and horizontal elements of the lateral-force-resisting system and any strengths or weaknesses of that system.


1201.2—Report1201.2—Report

Workbook Page 81



The language in the 2009 edition required that the engineer describe a complete load path, whether one was present or not. Further, the term “earthquake resistant

features” was vague and has been deleted.


1201.2—Report1201.2—Report

Workbook Page 81

Wording in the 2009 edition allowed repairs with original or like materials and original methods of construction.

This was been expanded to specify that the use of hazardous materials, such as asbestos and lead-based paint, that would not be code compliant in new construction, would not be permitted in repairing buildings of similar occupancy, purpose and location.


1202.1—General1202.1—General

Multi-use StructureMulti-use Structure Case Study Background Information: An existing 3 story multi-tenant Group B building

in Dublin, Ohio is being converted into a multi-use structure. The building is a 7,500 square feet per floor (687

m2), constructed with masonry exterior walls and concrete floors supported on open web steel joists. Currently the building does not have sufficient

water supply for a sprinkler system without the installation of a new fire pump.




Multi-use StructureMulti-use Structure Scope of Work Alterations need to be made to 100 percent of

the ground floor; 60 percent of the second floor and 25 percent of the third floor. Additionally, there is a change of occupancy

on the entire first floor from Group B to a restaurant (Group A-2).

Case Study ~ Historical LibraryCase Study ~ Historical Library


What we know:What we know: The addition consists of: An 880 square foot basement expansion An elevator Accessible restrooms A staff mezzanine


What we know:What we know: Alteration consists of adding a second means of

egress for all floors and some other miscellaneous alterations.

It has been determined that the library is a contributing building within the proposed boundary increase for the West Chester downtown historical district and a letter has also been submitted by the Pennsylvania Historical Commission.


Discussion Activity QuestionsDiscussion Activity Questions

1. Will the historical provisions be applicable to this building?


2012 IEBC 2012 IBCYes. Section 202 definition of historic buildingsincludes buildings that contribute to a historicdistrict. Chapter 12, Historic Buildings, couldbe used.

No. The historic building definition inSection 202 does not include contributingbuildings to a historic district. Section3407 could not be used.




2. Will a special report be required to be submitted?


2012 IEBC 2012 IBCDepends on whether the code official finds itnecessary to ask for a report. (Section 1201.2)

No. There are no provisions in Chapter34 to allow the code official to ask for anadditional report.


3. Currently, the building has two exit doors: A 30 inch by 89 inch door

(762 mm by 2261 mm) A 31 inch by 80 inch door

(787 mm by 2032 mm) Are the existing doors required to be widened,

even though a new complying exit door is being provided as part of the alteration project?


2012 IEBC 2012 IBCThe existing doors are not required to bewidened, as they comply with the capacitybased on occupant load (Even assuming theentire buildings occupant load passes through one of three doors the required width would be 84 X 0.2 = 16.8” for elements other than stairways and 84 X 0.3 = 25.2” for stairways, much below what is already provided at 30” and 31”). However, the code official can require the doors to be widened if in their opinion the doors are not wide enough for a person to pass through. (Section 1203.3)

One or both of the existing doors could possibly be required to be widened ifthey are in the area of alterations or if they will be serving any part of the newadditions. (Section 3403.1)


4. Assuming there will not be a fire barrier constructed between the new library basement addition and the existing basement, will a sprinkler system be required?

If yes, in what parts of the building?


2012 IEBC 2012 IBC Because the A-3 fire area is being expanded, itis below the level of exit discharge and is notseparated by a fire barrier, a sprinkler system will be required in the entire building. (IEBC Section 1102.3 and IBC Section 903.2.1.3)

Only the basement addition will require asprinkler system. (Sections 3403.1 and903.2.1.3)


5. If the installation of the sprinkler system in the entire building adversely affects the historical character of the building, what might be done?


2012 IEBC 2012 IBCSeparate the basement addition from the restof the building with fire barriers and horizontalassemblies, then a sprinkler system is required in the addition only. (IEBC Section 1102.3 and IBC Section 903.2.1.3)

An evaluation of the buildings height andarea (with the addition) would need to beperformed as it relates to Chapter 5 of the IBC. (Sections 3403.1 and903.2.1.3)




6. The handrails and guards at the existing stairs are not in compliance with the current building code. Are the handrails and guards required to be brought up to code?


2012 IEBC 2012 IBCThe existing handrails and guards can remain as they are as long as they are not structurally dangerous. (Section 1203.9)

The existing handrails and guards canremain as they are as long as they arenot being altered. (Section 3404.1)


7. Are the new handrails and guards required to comply with the IBC?


2012 IEBC 2012 IBC Yes. (Section 1101.1)

Yes. (Section 3403.1)
