Complete Strategic Guide: Obtaining the RBQ 1.2 Licence – Small Buildings Contractor

1. What Is the RBQ 1.2 Licence and Who Needs It?

The RBQ 1.2 licence — Small Buildings Contractor (Entrepreneur en petits bâtiments) — is one of the most versatile construction licences issued by the Régie du bâtiment du Québec (RBQ). It authorizes construction work for buildings covered by Part 9 of the National Building Code of Canada 2015 that are not covered by subcategories 1.1.1 or 1.1.2 (guarantee plan buildings). This includes:

• Small commercial, industrial, and institutional buildings falling under Part 9 (up to 3 storeys, 600 m² building area);
• Residential buildings under subcategories 1.1.1 and 1.1.2 when work is performed as a subcontractor for a 1.1.1 or 1.1.2 licence holder;
• Tents covered by the Regulation under the Building Act.

It also covers work in subcategories 2.6, 3.1, 4.1, 5.1 and 6.1 when related to a building or tent covered by this subcategory. This makes the 1.2 licence the go-to credential for contractors working on small-scale projects across all occupancy types.

2. Scope of the Licence: What Types of Work Does It Authorize?

The RBQ 1.2 licence covers a broader range of building types than the 1.1.1 or 1.1.2, which are restricted to new residential buildings under a guarantee plan. The 1.2 encompasses all Part 9 buildings regardless of occupancy — residential, commercial, industrial, or institutional — as long as they meet the size limits of Part 9 (generally 3 storeys or less, 600 m² or less in building area).

The scope includes new construction, as well as renovation, restoration and transformation work under Part 10 of the Construction Code — a key differentiator from the 1.1.1 and 1.1.2 licences, which cover only new construction. This makes the 1.2 particularly relevant for contractors who handle both new builds and renovation projects.

This licence does not cover buildings that exceed Part 9 limits (larger buildings governed by Part 3). Contractors working on those projects need the RBQ 1.3 — General Buildings Contractor licence.

3. RBQ Exam Format: What to Expect

• Question type: Multiple choice (MCQ)
• Duration: 3 hours (180 minutes)
• Passing grade: 60%
• Languages: French or English
• Skills assessed: 214 skills across 55 competency elements
• Exam type: Mixed (open book + closed book)
• Tools provided: Calculator, ruler, paper and pencil

With 214 skills, the 1.2 exam is one of the more demanding RBQ exams. It tests your ability to apply construction codes, legislation, and technical standards to a wide variety of small building scenarios — from wood-frame houses to small commercial properties.

4. Exam Documentation: Open Book vs. Closed Book

The RBQ 1.2 exam is a mixed exam: 2 documents are provided at the exam (open book) and 4 must be memorized (closed book). Note that this ratio is less favourable than the 1.1.1/1.1.2 exams (which provide 3 documents) — you have more material to memorize for the 1.2.

Documents PROVIDED During the Exam (Open Book)

• Canadian Wood-Frame House Construction — Canada (CMHC) — The comprehensive reference guide for wood-frame construction practices, including framing details, foundation systems, and building envelope assemblies.
• Quebec Construction Code — Chapter I, Building (NBC amended 2010) — The primary technical reference for building requirements, structural standards, fire safety, and accessibility provisions.

Documents to MEMORIZE (Closed Book)

• Building Act (CQLR, c. B-1.1) — The foundational statute governing construction, safety, and contractor qualifications in Quebec.
• Regulation respecting the professional qualifications of contractors and owner-builders (CQLR, c. B-1.1, r. 9) — Defines the qualification requirements, subcategories, and conditions for obtaining a licence.
• Regulation respecting the guarantee plan for new residential buildings (CQLR, c. B-1.1, r. 8) — Establishes the guarantee obligations applicable to contractors of new residential buildings.
• Safety Code for Construction Work (CQLR, c. S-2.1, r. 4) — Establishes health and safety standards for construction sites.

5. The 10 Training and Competency Modules

Module 1 — Legislative, Normative and Regulatory Framework (28 skills — 13%)

Covers the Building Act, the Professional Qualifications Regulation, the guarantee plan regulation, and associated legal obligations. The 1.2 exam includes the full legislative framework applicable to all small buildings, not just residential ones.

Module 2 — Building Design (14 skills — 7%)

Covers principles of building design, site analysis, building orientation, spatial planning, and compliance with municipal regulations. For the 1.2, design considerations span residential, commercial, and institutional small buildings.

Module 3 — Building Excavation and Foundation (26 skills — 12%)

Covers excavation safety, soil conditions, footing design, foundation wall construction, waterproofing, drainage systems, frost protection, and protection against underground gases. The second-heaviest module alongside Module 1.

Module 4 — Building Structure (22 skills — 10%)

Focuses on structural systems for Part 9 buildings, including light wood-frame construction, load paths, connections, bracing, and span tables. Includes structural calculation skills for footing sizes, joist spans, and header dimensions.

Module 5 — Building Envelope (15 skills — 7%)

Addresses thermal insulation, air barriers, vapour barriers, cladding systems, fenestration, and moisture management. The CMHC guide (open book) is a key reference for envelope construction details.

Module 6 — Fire Protection and Means of Egress (45 skills — 21%)

The most heavily weighted module on the exam. With 45 skills, fire protection alone accounts for over one-fifth of the total. Covers fire separations, compartmentalization, means of egress, limiting distances, firefighting measures, detection and emergency lighting systems, and construction execution for fire protection. This module draws on both Part 3 and Part 9 of the Code.

Module 7 — Building Mechanical Systems (16 skills — 7%)

Covers plumbing, HVAC, sanitary equipment, and water heaters. Includes requirements for supply and drainage piping, venting, gas installations, and mechanical ventilation.

Module 8 — Architectural and Functional Components (18 skills — 8%)

Addresses interior finishes, accessibility requirements, stairways, guards, handrails, and functional elements of buildings across all occupancy types covered by Part 9.

Module 9 — Building Renovation, Restoration and Transformation (14 skills — 7%)

Unlike the 1.1.1 and 1.1.2, this module IS assessed for the 1.2 licence. Covers the requirements of Part 10 of the Construction Code for renovation work, including structural assessment of existing buildings, code compliance for alterations, and the specific challenges of working with existing structures.

Module 10 — Sustainable Development and Environment (16 skills — 7%)

Covers environmental regulations, energy efficiency requirements, sustainable construction practices, and the Sustainable Development Act applied to small buildings.

6. Key Competencies and Technical Requirements (Official Context)

Fire Protection Across Multiple Occupancy Types

The 1.2 licence covers buildings of all occupancy types under Part 9, making fire protection more complex than for the 1.1.1/1.1.2 exams. Candidates must understand fire separation requirements not only between residential dwelling units, but also between different occupancy types within the same building — for example, a commercial space on the ground floor with residential above. The exam tests your ability to determine fire-resistance ratings for separations between major occupancies (Article 3.1.3.1 of the Code) and to apply Part 9 fire protection requirements (Section 9.10) to a wide range of small building configurations.

The CMHC Guide: A Unique Open-Book Resource

Unlike the 1.1.1 and 1.1.2 exams, the 1.2 provides the CMHC guide "Canadian Wood-Frame House Construction" instead of the Professional Qualifications Regulation. This guide is a practical construction manual with detailed illustrations of wood-frame assemblies, foundation details, and envelope systems. The exam tests your ability to cross-reference the CMHC guide with the Construction Code — for example, verifying that a framing detail shown in the CMHC guide meets the structural requirements of Part 9. Mastering the CMHC guide's table of contents is essential for quick navigation during the exam.

Renovation Work Under Part 10

The 1.2 licence is one of the few that includes renovation, restoration and transformation work. Part 10 of the Construction Code establishes how code requirements apply to existing buildings undergoing alterations. Candidates must understand concepts like "change of major occupancy classification," "increased hazard index," and the triggers that require upgrading an existing building to meet current code. This module adds 14 skills not tested on the 1.1.1/1.1.2 exams.

Building Classification and Part 9 Boundaries

A core competency for the 1.2 is determining whether a building falls under Part 9 or Part 3 of the Code. This classification depends on building area, height, major occupancy, and sprinkler protection. The exam frequently presents scenarios where candidates must classify a building and then apply the appropriate code requirements. Getting the classification wrong cascades into incorrect answers on fire protection, structural, and egress questions.

Foundation Design for Diverse Building Types

With 26 skills (12% of the exam), Module 3 covers foundation design for the full range of Part 9 buildings. Beyond residential foundations, candidates must understand requirements for small commercial and institutional buildings, including accessibility requirements for foundations (ramps, barrier-free entrances), protection against underground gases including radon, and the specific challenges of foundation work in Quebec's varied soil conditions and freeze-thaw cycles.

Four Closed-Book Documents: A Heavier Memorization Load

The 1.2 exam requires memorizing 4 documents (vs. 3 for the 1.1.1/1.1.2). The addition of the Professional Qualifications Regulation and the Guarantee Plan Regulation to the closed-book list means candidates must understand licence conditions, contractor classifications, and guarantee mechanisms without being able to look them up during the exam. This is a significant strategic consideration: candidates who invest time memorizing these regulatory frameworks gain an advantage on Module 1 questions.

7. Preparation Strategy and Tips for Success

The RBQ 1.2 exam covers 214 skills across 10 assessed modules (including renovation) — the broadest scope among the small building licences. Here is a recommended strategy:

Phase 1 — Master the 4 closed-book documents. The Building Act, Professional Qualifications Regulation, Guarantee Plan Regulation, and Safety Code for Construction Work must all be memorized. This is a heavier load than the 1.1.1/1.1.2 exams. Use Prof-RBQ.ca's flashcards systematically — start early and review daily.

Phase 2 — Dominate Module 6 (Fire Protection). With 45 skills (21% of the exam), this module alone can determine your pass or fail. Focus on fire separations between different occupancy types, fire-resistance ratings, sprinkler requirements, and exit arrangements. The Construction Code (open book) is your primary reference — learn to navigate Section 9.10 and Part 3 fire protection articles quickly.

Phase 3 — Learn to navigate both open-book documents. Master the CMHC guide's chapter structure for wood-frame construction details, and the Construction Code's table of contents for regulatory requirements. Practice cross-referencing between the two documents.

Phase 4 — Don't neglect Module 9 (Renovation). Unlike the 1.1.1/1.1.2 exams, the 1.2 tests 14 skills on renovation work. Part 10 of the Code has specific rules — learn them.

Phase 5 — Complete full timed simulations. Before the exam, do at least 2–3 full practice exams under timed conditions. With 214 skills, you need roughly 50 seconds per question.
