           Building and Development Branch         4
Background:
Building Code – 2008 Consultation
  The government is proposing to make changes
  to the Building Code that would:
    • Introduce administrative requirements
      respecting maintenance inspections of existing
      on-site sewage systems;
    • Establish technical requirements for tertiary
      treatment unit disposal beds (“area beds”) that
      form part of certain on-site sewage systems;
      and
    • Require fire sprinklers in multiple-unit
      residential buildings greater than three storeys
           Building and Development Branch           5
Background:
Building Code – 2008 Consultation


 MMAH is currently undertaking a consultation to
 seek public input regarding:
  • The content of these proposed changes
  • Implementation timing, should the changes be adopted




           Building and Development Branch           6
Background:
Building Regulation in Ontario
   The Building Code Act, 1992 (BCA) sets out the
   legislative framework governing the construction,
   renovation and change of use of buildings
   The Building Code is a regulation made under the BCA
   and sets out technical and administrative requirements
   Enforcement of the BCA and Code is the responsibility of
   principal authorities:
     • Principal authorities are mainly municipalities
     • But in some areas of the province, boards of health and
       conservation authorities are responsible for on-site
       sewage system enforcement

             Building and Development Branch                  7
Background:
Building Regulation in Ontario

   The BCA sets out a number of “purposes” of the
   Building Code, including
    • Public health and safety    •   Structural sufficiency
    • Fire protection             •   Conservation
    • Environmental integrity     •   Barrier-free accessibility

   The proposed changes to the Building Code are related
   to these purposes




            Building and Development Branch                        8
Background:
Building Regulation in Ontario

   The Building Code does not set requirements for
   existing buildings where no work is being proposed
   Fire safety of existing buildings falls under the Fire
   Protection and Prevention Act, 1997 and Fire Code:
      Responsibility of the Ministry of Community Safety and
      Correctional Services through the Office of the Fire
      Marshal




            Building and Development Branch                    9
Background:
Code Development in Ontario

 Ontario’s first Building Code came into force in
 1975 and new codes are released approximately
 every five years:
   • The current Code came into effect in 2006 and
     the next edition is anticipated in 2010-2011
 Ontario’s Code is, however, subject to interim
 amendments
 The present consultation proposes interim
 changes to the 2006 Building Code


           Building and Development Branch          10
Background:
Code Development in Ontario

 The model National Building Code (mNBC) is
 developed through a joint Federal/Provincial/
 Territorial process coordinated by the Canadian
 Commission on Building and Fire Codes (CCBFC)
 Ontario’s Code is harmonized to a large degree with
 the mNBC




           Building and Development Branch     11
Background:
Code Development in Ontario

 There are certain areas where Ontario’s Code
 and the mNBC differ - these are areas where
 Ontario chooses to pursue its own policy
 directions:
    • Unique Code requirements (e.g. energy efficiency,
      water conservation)
    • Consolidation of construction-related regulations in
      the Building Code, including on-site sewage
      systems, pools, spas, and rapid transit stations
    • Higher or modified requirements in areas of
      overlapping scope such as barrier-free access

           Building and Development Branch             12

Consultation Process:
Transition Issues

 Should the Government proceed with the proposed
 amendments to the Building Code, the timing for the
 introduction of these amendments and their “in force”
 date(s) will take into consideration factors, including:
  • Appropriate transition periods;
  • Industry capacity and preparedness;
  • Typical project build times and construction seasons; and
  • Timing of related regulations under the Clean Water Act,
    2006 which may have an impact on on-site sewage system
    enforcement

   Building and Development Branch   20
Sewage System Maintenance Inspections:
Background

   The Building Code regulates the construction, extension,
   alteration and repair of small on-site sewage systems
   (e.g., septic systems)
   In addition, the Code contains standards for the operation
   and maintenance of existing on-site sewage systems
   Principal authorities may inspect sewage systems to
   determine whether they are unsafe
   Neither the BCA nor the Code currently require periodic
   inspections of existing systems by principal authorities



             Building and Development Branch             21
Sewage System Maintenance Inspections:
The Clean Water Act

  The Clean Water Act, 2006 (CWA) made
  consequential amendments to the BCA concerning
  maintenance inspections of on-site sewage systems
  Changes to the Building Code are required to establish
  and govern the mandatory maintenance inspection
  programs
  These amendments would relate to assuring compliance
  with the operation and maintenance requirements of the
  Building Code



            Building and Development Branch           22
Sewage System Maintenance Inspections:
The Clean Water Act
The CWA:
 • Was introduced following Justice
   O’Connor’s Inquiry into the
   Walkerton tragedy
 • Is intended to ensure that
   communities are able to protect
   their municipal drinking water
   supplies through developing
   collaborative, locally driven,
   science-based drinking water
   source protection plans
Among other matters, improperly
installed and poorly maintained
septic systems were identified by
Justice O’Connor as a potential
threat to drinking water

                Building and Development Branch   23
Sewage System Maintenance Inspections:
New Legislative Authority

  Amendments to the BCA which came into force on
  July 3, 2007, establish a legislative framework for
  sewage system maintenance inspections
  These amendments authorize regulations to establish
  programs to enforce standards for the maintenance and
  operation of existing sewage systems, and to require that
  these programs be enforced by principal authorities
  The amendments also authorize principal authorities to
  establish “discretionary” maintenance inspection
  programs for existing sewage systems



            Building and Development Branch            24
Sewage System Maintenance Inspections:
New Legislative Authority (cont.)
The principal authorities that would enforce programs
would be the same authority that current enforces BCA
requirements related to sewage systems:
 • A municipality;
 • A board of health or conservation
   authority that undertakes
   enforcement under an agreement
   with a municipality; or
 • A board of health or conservation
   authority prescribed in the Building
   Code

              Building and Development Branch   25
Sewage System Maintenance Inspections:
New Legislative Authority (cont.)

  Inspections would be undertaken by inspectors appointed
  by the principal authority
  Principal authorities may require that fees be paid for
  maintenance inspections, and can prescribe the amounts
  of the fees
  An inspector may enter upon land and into buildings at
  any reasonable time without a warrant for the purpose of
  conducting a maintenance inspection
  However, entry into dwellings (as is the case for all BCA
  inspections) would require a warrant unless the consent of
  the occupier is obtained, or there is an immediate danger
  to health and safety

             Building and Development Branch            26
Sewage System Maintenance Inspections:
New Legislative Authority (cont.)

  An inspector conducting a sewage system maintenance
  inspection who finds a contravention of the BCA or the
  Building Code may make an order directing compliance
  with the BCA or the Code
  Inspectors undertaking sewage system maintenance
  inspections could also exercise powers to:
     Issues orders requiring that tests be taken and require
     that information be provided; and
     Issue “unsafe” orders
  Subject to the regulations, principal authorities may
  accept “third party certificates” as an alternative to
  inspections

              Building and Development Branch                  27
Sewage System Maintenance Inspections:
New Legislative Authority (cont.)

  The BCA, as amended by the CWA, sets out the authority
to establish regulations that would affect sewage system
maintenance inspection programs:
   • Types of sewage systems affected;
   • The areas where Required Programs would apply;
   • The areas where principal authorities may choose to apply
     Discretionary Programs;
   • The qualification of inspectors;
   • The frequency of inspections;
   • The type and manner of inspections;
   • Authorize principal authorities to accept third party certificates as
     an alternative to an inspection; and
   • The classes of persons who can sign a third party certificate

                Building and Development Branch                       28
Sewage System Maintenance Inspections:
Proposed Code Amendments
Types of systems affected:
  All systems currently regulated through Part 8 of Division B of the
  Building Code would be subject to sewage system maintenance
  inspection programs, including:
    • Class 1 — a chemical toilet,
      an incinerating toilet, a
      recirculating toilet, a self-
      contained portable toilet
      and all forms of privy
    • Class 2 — a greywater system
    • Class 3 — a cesspool
    • Class 4 — a leaching bed system
    • Class 5 — a system that requires
      or uses a holding tank

                  Building and Development Branch                       29
Sewage System Maintenance Inspections:
Proposed Code Amendments - Div. C

Area of Application (Required Programs):
  Would apply to sewage systems located in “prescribed areas”
  Anticipated to be a subset of "vulnerable areas" identified in an
  assessment report included in a source protection plan subject to
  posting on the environmental registry in accordance with section 30 of
  the CWA
  The method of delineating these areas will be set out in future technical
  rules under the CWA
  The areas will be identified in assessment reports attached to
  individual source protection plans
    • Note: Questions related to the Clean Water Act, 2006 and source
      protection plans can be directed to the Source Protection Programs Branch
      of the Ministry of the Environment at: source.protection@ontario.ca

  Sewage System Maintenance Inspections:
  Proposed Code Amendments - Div. C

Area of Application
(Discretionary Programs):
   Under the BCA principal
   authorities could choose to
   establish Discretionary Programs
   It is proposed that the Building
   Code will establish a requirement
   that Discretionary Programs
   would apply in all areas within the
   jurisdiction of a principal authority
   not covered by Required
   Programs
 (Code Change No. C-01-10-01)

                      Building and Development Branch   31
Sewage System Maintenance Inspections:
Proposed Code Amendments - Div. C

Qualifications of Inspector:
    Sewage system inspectors would need the same
    qualifications as persons who currently carry out plans
    review and inspection functions for sewage systems
    These persons need to pass the examination program
    for this class of inspector established by the MMAH
    (currently a legal examination plus the on-site sewage
    system examination)
    However, inspectors would be exempt from this
    qualification requirement if they do not issue orders and
    are supervised by a qualified chief building official or
    inspector (Code Change No. C-03-01-01)
              Building and Development Branch             32
Sewage System Maintenance Inspections:
Proposed Code Amendments - Div. C

Frequency of Inspections (Required Programs):
  Where a building permit under the BCA has been issued for the system
  or it has been previously inspected under a Discretionary Program:
      Initial inspections would need to take place within five years following
      the date on which the first applicable source protection plan comes into
      effect

  Otherwise, initial inspections would need to take place within three
  years following the date on which the first applicable source protection
  plan comes into effect
  Subsequent inspections would need to take place once within each five
  year period following the initial inspection
(Code Change No. C-01-10-01)

 Sewage System Maintenance Inspections:
 Proposed Code Amendments - Div. C
Type and Manner of Inspections:
  Inspections would require a site visit
  The inspector may consider reports concerning whether the sewage system
  or a part of the sewage system complies with the BCA or the Building Code
  The consultation paper includes a proposed Code “Appendix Note” that
  would provide guidance with respect to the inspection process
  The proposed Appendix Note includes:
    • Identification of applicable areas and sewage systems within those areas;
    • Inspection notification; and
    • Inspection methodology


(Code Change No. C-01-10-01)

Sewage System Maintenance Inspections:
Proposed Code Amendments - Div. C

Third Party Certificates:
  Principal authorities, as an alternative to conducting an inspection,
  could accept a “third party” certificate
  Certificates would be in a form approved by the Minister
  Each certificate would confirm that a particular sewage system has
  been inspected and is in compliance with Section 8.9. of Division B
  Certificates would need to be signed by a designer or a sewage
  system installer registered under the Building Code
  A person signing a certificate cannot be in a conflict of interest as
  defined in the Building Code

(Code Change No. C-01-10-01)

Proposed Code Amendments - Transition
 Building Code requirements related to Discretionary Programs
 would come into force on January 1, 2009
 Required Programs will not be in force until a source protection
 plan for a given area is in effect
 The plans are required under the Clean Water Act, 2006, and it is
 anticipated that they will be submitted to the Minister of the
 Environment by 2012

      Area Beds




Building and Development Branch   39
Area Beds:
Background
 Area beds are a type of soil absorption system used in
 conjunction with an on-site sewage system that includes a
 tertiary treatment unit listed in Supplementary Standard
 SB-5 referenced in the Building Code
 Area beds are designed to further treat and disperse effluent
 within the soil
 They are comprised of a stone layer situated on top of a
 sand layer and may be installed in or on soil




            Building and Development Branch             40
Area Beds:
Background

 Some area bed designs allow for the tertiary treatment
 unit (those with open bottoms) to be installed on top of the
 stone layer, whereas other configurations have the
 tertiary treatment unit located beside the area bed
   • In the latter design, distribution pipes are used to
     convey effluent within the stone layer
 Standards for “area bed” systems are not currently set out
 in the Building Code, but their use has been authorized by
 the Building Materials Evaluation Commission (BMEC)



             Building and Development Branch             41
Area Beds:
Background
 The BMEC is a regulatory body authorized under the BCA
 whose mandate is to evaluate new and innovative
 construction materials, systems and designs for use in
 construction in Ontario
 Since 1998 the BMEC has issued eight separate “area
 bed” authorizations (Authorizations of the BMEC are
 available on the Building Code website)
 The use of area beds has become widespread
 The Ministry is proposing to establish area bed
 requirements in the Building Code


            Building and Development Branch            42
  Area Beds:
  Proposed Code Amendments – Div. A

Residential Fire Sprinklers




    Building and Development Branch   53
Residential Fire Sprinklers:
Background
   As noted, “public health and safety” and “fire
   protection” are among the purposes of the Building
   Code
   Fire safety requirements have been featured in the
   Code since its inception in 1975
   Ontario’s buildings have an excellent record of fire
   safety:
      • The province has one of the lowest fire fatality rates in
        the country
      • Since first Building Code introduced over 30 years
        ago fire fatality rates have declined steadily

              Building and Development Branch                   54
Residential Fire Sprinklers:
Background

  These reductions have been, in part, due to enhanced
  Building Code requirements over time
  For example, the Code now requires:
   • Smoke alarms on every level in a house;
   • Interconnected smoke alarms in a house; and
   • Enhanced early warning/notification and detection systems
     in larger buildings
  Further reductions in fire deaths have been achieved
  through enhanced standards in Ontario’s Fire Code,
  public fire safety education, awareness and residential
  inspection programs

              Building and Development Branch               55
Residential Fire Sprinklers:
Background
  The mNBC and other provinces require sprinklering of
  large multiple-unit residential buildings - generally higher
  than three storeys
  Ontario’s Building Code presently does not have this
  requirement
  Instead, Ontario’s Code has required additional fire safety
  measures not found in the mNBC




              Building and Development Branch              56
Residential Fire Sprinklers:
Keeping Ontario at Forefront of Safety

  While Ontario’s approach has achieved good results with
  respect to fire safety in residential buildings, the
  government is looking to keep Ontario’s Building Code at
  the forefront of fire safety
  This consultation seeks your views on proposed
  amendments to the Building Code to require fire
  sprinklers in multiple-unit residential buildings over three
  storeys in height
      This would include condominiums, rental apartment
      buildings, hotels, retirement homes and hostels
      Small residential buildings, including houses, would not
      be included

             Building and Development Branch                57
Residential Fire Sprinklers:
Keeping Ontario at Forefront of Safety
 Specific configurations of four
 storey “stacked townhouses”
 would also be exempted
 Buildings undergoing renovation:
  • The sprinklering requirements
    would apply to floor areas of
    existing buildings that undergo a
    change of major occupancy, and
    to additions to existing buildings
  • The new sprinklers would not
    apply to renovations of existing
    individual residential units

             Building and Development Branch   58
Residential Fire Sprinklers
Overview of Sprinkler Proposals
  Certain Code requirements for residential buildings
  greater than three storeys would be removed:
    The Code currently gives choice of whether to install sprinklers
    Where sprinklers are not installed, the Code currently requires
    compensating features including smoke control, heat detection,
    exiting, areas of refuge and emergency operation of elevators
    Elements of these features would no longer be applicable if
    sprinklers were mandatory
    Their removal would also increase harmonization with the
    mNBC

  Measures related to balconies and areas of refuge,
  which are alternatives to meeting Ontario’s current
  smoke control requirements for unsprinklered buildings,
  would also be removed
             Building and Development Branch                     59
Residential Fire Sprinklers
Overview of Sprinkler Proposals
In recognition of the benefits of sprinklered buildings, other
provisions are proposed to further harmonize Ontario’s Code
with the mNBC:
   • Examples include:
        Allowing non-masonry firewalls in high buildings
        Allowing combustible cladding on high buildings
At present, these provisions are not an option in Ontario even
if a building is sprinklered




              Building and Development Branch              60
Residential Fire Sprinklers
Overview of Sprinkler Proposals
It is also proposed that the maximum size for live-
work units be increased from 150 m2 to 200 m2:
  • This is an Ontario-specific issue, as the mNBC does not
    recognize live-work units
