The last section of the syllabus is a mix: the Part 11 compliance alternatives used in renovations, the Part 12 rule on motion sensors for lighting, and the Division C administrative rules a fire protection inspector meets every day, from who must design certain fire-related items to the notices, occupancy permits and alternative solutions.
Renovation compliance alternatives
Part 11 offers compliance alternatives in Tables 11.5.1.1.-A to F that may replace specific requirements when renovating (OBC Div. B 11.5.1.1.OBC Div. B 11.5.1.1. Compliance Alternatives(1) A compliance alternative shown in Table 11.5.1.1.-A, 11.5.1.1.-B, 11.5.1.1.-C, 11.5.1.1.-D/E or 11.5.1.1.-F may be substituted for a requirement contained in Part 3, 4, 6 or 8 where the chief building official is satisfied that compliance with the requirement is impracticable because, (a) of structural or…). The condition depends on which Part the requirement comes from:
| Requirement from | Condition to use a compliance alternative |
|---|---|
| Part 3, 4, 6 or 8 | the chief building official is satisfied compliance is impracticable because of structural or construction difficulties, or harm to a heritage building |
| Part 9 or 12 | no impracticability test |
Part 11 applies to buildings at least five years old (Div. A 1.3.3.3B.). A compliance alternative is a pre-approved substitute listed in the code. It is not an alternative solution, which needs its own documentation under Division C Part 2.
Motion sensors (Part 12)
Part 12 covers resource conservation and environmental integrity (12.1.1.2.OBC Div. B 12.1.1.2. Application(1) This Part applies to resource conservation and environmental integrity in the design and construction of buildings.). Its fire-relevant rule: lighting that provides minimum code illumination may be on motion sensors, except (12.2.4.1.OBC Div. B 12.2.4.1. Motion Sensors(1) Lighting installed to provide the minimum illumination levels required by this Code may be controlled by motion sensors except where the lighting (a) is installed in an exit, (b) is installed in a corridor serving patients or residents in a Group B, Division 2 or Division 3 occupancy, or (c) is required to conform…):
- lighting in an exit,
- lighting in a corridor serving patients or residents in B2 or B3,
- aisle lighting in theatres and similar spaces under 3.2.7.1.(10),
- any emergency lighting.
In public corridors and public access-to-exit corridors, sensors need fail-safe controllers and timers of at least 15 minutes.
Design by architects and engineers
The syllabus covers Div. C 1.2.1.2. except Sentence (1) (foundations). Fire-related design items (OBC Div. C 1.2.1.2.OBC Div. C 1.2.1.2. Design by Architect or Professional Engineer(1) A foundation of a building shall be designed by a professional engineer where, (a) the foundation is to be constructed below the level of the footings of an adjacent building and within the angle of repose of the soil, as drawn from the bottom of the footings, or (b) underpinning of a foundation is to be…):
| Item | Designer |
|---|---|
| Sprinkler protected glazed wall assembly (3.1.8.20.) | professional engineer |
| Shelf and rack storage system (3.16.) | professional engineer |
| Time-based egress analysis for rack storage | architect or engineer, or both |
| Tent framing and anchorage over 225 m² | professional engineer |
| Projecting sign over 115 kg, roof sign face over 10 m², sign on a parapet | architect or engineer, or both |
Permits, occupancy and notices
Division C applies to all buildings and is administered under the Act (1.1.1.1.OBC Div. C 1.1.1.1. Application(1) This Part applies to all buildings covered in this Code. (See Article 1.1.1.1. of Division A.), 1.1.1.2.OBC Div. C 1.1.1.2. Conformance with Administrative Requirements(1) This Code shall be administered in conformance with the Act.).
Permit exemptions (1.3.1.1.OBC Div. C 1.3.1.1. Requirement for Permits(1) A person is exempt from the requirement to obtain a permit under section 8 of the Act, (a) for the demolition of a farm building located on a farm, (b) subject to Sentence (2), for the construction or demolition of a building in territory without municipal organization, or (c) for the construction of a Class 1…) include demolishing a farm building on a farm, small tents (max 60 m² total, not attached, more than 3 m from other structures), sheds up to 15 m² without plumbing, and demountable stages outside 3.17. Occupants must have left before demolition starts unless their safety is unaffected.
Change of use permits under section 10 of the Act (1.3.1.4.OBC Div. C 1.3.1.4. Permits Under Section 10 of the Act(1) Except as provided in Sentence (2), the following changes in use of a building or part of a building constitute an increase in hazard for the purposes of section 10 of the Act and require a permit under section 10 of the Act: (a) a change of the major occupancy of all or part of a building that is designated with…) are needed for listed increases in hazard: a "Y" change in Table 1.3.1.4., splitting a Group C suite, A2 or A4 to gaming, farm building to a non-farm occupancy or to G1, to a post-disaster building or retirement home, or an unknown previous use. No section 10 permit is needed if a section 8 permit already covers the construction.
The permit (or a copy) is posted conspicuously during the work, and the permitted drawings, authorizations and rulings are kept on site (1.3.2.1.OBC Div. C 1.3.2.1. Permit Posting(1) Where a permit has been issued pursuant to the Act, the person to whom it is issued shall have the permit or a copy of it posted at all times during construction or demolition in a conspicuous place on the property in respect of which the permit was issued., 1.3.2.2.OBC Div. C 1.3.2.2.

Occupancy Permit — General(1) Except as permitted in Sentence 1.3.3.2.(1), a person may occupy or permit to be occupied any building or part of it that has not been fully completed at the date of occupation where the chief building official or a person designated by the chief building official has issued a permit authorizing occupation of the…) needs a permit. Fire-related conditions include: fire separations and closures complete on occupied storeys; exits complete from the top occupied floor to grade; shafts complete with a temporary separation above; service room separations done; corridor and exit lighting working; standpipe, sprinkler and fire alarm systems operational up to the occupied storeys with pumper connections; extinguishers installed; and firefighting access routes accessible. Small residential buildings have their own lists (1.3.3.2., 1.3.3.4.), mid-rise wood buildings under 3.2.2.51. or 3.2.2.60. a stricter one requiring completion throughout (1.3.3.5.OBC Div. C 1.3.3.5.

Prescribed notices (1.3.5.1.OBC Div. C 1.3.5.1. Prescribed Notices(1) This Article sets out the notices that are required under section 10.2 of the Act. (2) The person to whom a permit under section 8 of the Act is issued shall notify the chief building official or, where a registered code agency is appointed under the Act in respect of the construction to which the notice relates…) for fire protection: substantial completion of all fire separations, closures and fire protection systems (standpipe, sprinkler, fire alarm, emergency lighting), of fire access routes, and readiness to test fire service mains. As-constructed plans may be demanded where a by-law allows (1.3.6.1.OBC Div. C 1.3.6.1. Application(1) Where a by-law, resolution or regulation has been made by a principal authority under clause 7(1)(g) of the Act, the chief building official may require that as constructed plans for the whole of, or any part or system of, a building or any class of buildings be provided by the persons responsible for the…).
Alternative solutions and rulings
A person proposing an alternative solutionOBC Div. A 1.4.1.2.(1) Alternative solutionAlternative solution means a substitute for an acceptable solution. gives the chief building official or registered code agency documentation identifying the applicable objectives, functional statements and acceptable solutions and showing, by past performance, tests or evaluation, that the required performance level is met, including assumptions and maintenance needs (OBC Div. C 2.1.1.1.OBC Div. C 2.1.1.1. Documentation(1) The person proposing the use of an alternative solution shall provide documentation to the chief building official or registered code agency that, (a) identifies applicable objectives, functional statements and acceptable solutions, and (b) establishes on the basis of past performance, tests described in Article…). Where no test method exists, tests simulate or exceed service conditions or compare against an accepted product (2.1.1.2.OBC Div. C 2.1.1.2. Tests(1) Where no published test method to establish the suitability of an alternative solution proposed under Article 2.1.1.1. exists, then the tests used for the purposes of that Article shall be designed to simulate or exceed anticipated service conditions or shall be designed to compare the performance of the material…).
The Minister may approve an alternative material, system or design by ruling only where it is consistent with a Building Code Commission decision, an approval in the whole of another province or territory, or an NBC or NPC revision approved by the national commission (2.4.2.1.OBC Div. C 2.4.2.1. Criteria(1) Sentence (2) sets out criteria to be followed by the Minister when making a ruling under clause 29(1)(c) of the Act to approve the use of an alternative material, system or building design. (2) The Minister’s approval of the use of an alternative material, system or building design referred to in Sentence (1) may…). Ministerial interpretations are posted on the Building Code website and given in writing on request (2.4.3.1.OBC Div. C 2.4.3.1. Interpretations By Minister(1) Every interpretation issued by the Minister under section 28.1 of the Act shall be made available to the public, (a) by posting the interpretation on the Building Code website, and (b) by providing a written copy of the interpretation on receipt of a request for it.).
Common traps: compliance alternatives (Part 11 tables) versus alternative solutions (Div. C 2.1.); the 60 m² tent permit exemption versus the 225 m² engineering threshold; thinking an occupancy permit needs the whole building finished.
