Complete Strategic Guide: Obtaining the RBQ 1.1.1 Licence – Contractor for New Residential Buildings Covered by a Guarantee Plan, Class I

1. What Is the RBQ 1.1.1 Licence and Who Needs It?

The RBQ 1.1.1 licence — Contractor for New Residential Buildings Covered by a Guarantee Plan, Class I — is mandatory for any contractor who wishes to act as a qualifier (répondant) for new residential construction projects in Quebec. Issued by the Régie du bâtiment du Québec (RBQ), this licence authorizes the construction of:

• Single-family homes (detached, semi-detached, or row houses), whether or not held in divided co-ownership;
• Multi-family buildings from duplex to quintuplex, not held in divided co-ownership;
• Multi-family buildings with more than 5 dwelling units held by a non-profit organization or cooperative, not in divided co-ownership.

It also covers construction work in subcategories 2.6, 3.1, 4.1, 5.1 and 6.1 when related to a new residential building falling under this subcategory. Every new residential building covered by the guarantee plan requires its contractor to hold this licence, making it a foundational credential for the Quebec residential construction sector.

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

The RBQ 1.1.1 licence targets new residential construction covered by the Regulation respecting the guarantee plan for new residential buildings. In practice, this means Class I buildings governed primarily by Part 9 of the Quebec Construction Code — buildings of 3 storeys or less and not exceeding 600 m² in building area.

The scope includes single-family homes in all their configurations (detached, semi-detached, row houses) and small multi-family buildings. The licence also extends to foundation work, framing, building envelope, fire protection systems, mechanical systems, and architectural components — as long as they form part of a new residential building covered by this subcategory.

This licence does not cover renovation, restoration or transformation work (which falls under different subcategories), nor does it cover buildings in divided co-ownership (which require the RBQ 1.1.2 — Class II licence). Large-scale multifamily buildings subject to Part 3 of the Code typically require additional licensing.

3. RBQ Exam Format: What to Expect

• Question type: Multiple choice (QCM)

4. Exam Documentation: Open Book vs. Closed Book

The RBQ 1.1.1 exam is a mixed exam: 3 documents are provided at the exam (open book) and 3 must be memorized (closed book). This distinction is critical for your study strategy.

Documents PROVIDED During the Exam (Open Book)

• 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 and maintaining a licence.
• Regulation respecting the guarantee plan for new residential buildings (CQLR, c. B-1.1, r. 8) — Establishes the guarantee obligations, coverage, and mechanisms applicable to contractors of new residential buildings.
• Quebec Construction Code, Chapter I – Building, and the National Building Code of Canada 2015 (amended) — The primary technical reference for building requirements, structural standards, and fire safety provisions.

Documents to MEMORIZE (Closed Book)

• Building Act (CQLR, c. B-1.1) — The foundational statute governing construction, safety, and contractor qualifications in Quebec.
• Safety Code for Construction Work (CQLR, c. S-2.1, r. 4) — Establishes health and safety standards for construction sites, including fall protection and excavation safety.
• Sustainable Development Act (c. D-8.1.1) — Sets the principles and framework for sustainable development in Quebec construction and public administration.

5. The 10 Training and Competency Modules

Module 1 — Legislative, Normative and Regulatory Framework (28 skills — 16%)

The largest module, covering the Building Act, the Regulation respecting the professional qualifications of contractors, the guarantee plan regulation, and associated legal obligations. This module requires thorough understanding of the contractor's legal responsibilities, licence conditions, and the regulatory environment governing residential construction in Quebec.

Module 2 — Building Design (14 skills — 8%)

Covers principles of building design for residential projects, including site analysis, building orientation, spatial planning, and compliance with municipal regulations and zoning requirements. Candidates must understand how design decisions affect code compliance and construction feasibility.

Module 3 — Building Excavation and Foundation (26 skills — 15%)

One of the exam's heaviest modules. Covers excavation safety, soil conditions, footing design, foundation wall construction, waterproofing, drainage systems, and protection against frost. Understanding the structural requirements for foundations under Part 9 of the Code is essential.

Module 4 — Building Structure (22 skills — 13%)

Focuses on light wood-frame construction as the primary structural system for Part 9 buildings. Covers floor systems, wall framing, roof structures, load paths, connections, and the application of span tables from the Code. Includes structural calculation skills.

Module 5 — Building Envelope (12 skills — 7%)

Addresses thermal insulation, air barriers, vapour barriers, cladding systems, fenestration, and moisture management. Candidates must understand the principles of heat, air, and moisture control to prevent building envelope failures in Quebec's climate.

Module 6 — Fire Protection and Means of Egress (26 skills — 15%)

Tied for the most skills alongside Module 3. Covers fire separations, fire-resistance ratings, limiting distances, smoke alarms, exits, egress travel distances, and firefighter access. Fire protection is a critical topic for all residential buildings, including those under Part 9.

Module 7 — Building Mechanical Systems (16 skills — 9%)

Covers plumbing, heating, ventilation, and air conditioning (HVAC) systems for residential buildings. Includes requirements for supply and drainage piping, venting, gas installations, and mechanical ventilation as required by the Code.

Module 8 — Architectural and Functional Components (18 skills — 10%)

Addresses interior finishes, accessibility requirements, stairways, guards, handrails, and functional elements of residential buildings. This module ensures candidates understand the livability and safety requirements beyond structural and mechanical systems.

Module 9 — Building Renovation, Restoration and Transformation (not assessed)

This module is not assessed for the RBQ 1.1.1 licence, which focuses exclusively on new construction. Renovation and transformation work falls under different licence subcategories.

Module 10 — Sustainable Development and Environment (10 skills — 6%)

Covers environmental regulations, energy efficiency requirements, sustainable construction practices, and the Sustainable Development Act. Candidates must understand how sustainability principles integrate into residential construction decisions.

6. Key Competencies and Technical Requirements (Official Context)

Foundation Design and Frost Protection Under Part 9

Quebec's cold climate makes foundation design a critical competency for the 1.1.1 exam. Candidates must understand frost penetration depths (typically 1.2 m to 1.8 m depending on the region), the requirements for footing dimensions under Table 9.15.3.4. of the NBC, and the drainage and waterproofing systems required to protect below-grade structures. The exam tests your ability to apply these requirements to specific soil conditions and building configurations — not just recall the minimum depth from the Code. Understanding the relationship between soil bearing capacity, footing width, and the number of storeys supported is essential.

Light Wood-Frame Construction and Span Tables

Part 9 buildings under the RBQ 1.1.1 scope rely primarily on light wood-frame construction. The exam evaluates your ability to use the span tables in Section 9.23 of the Code to determine joist sizes, rafter spans, stud spacing, and header dimensions. You must understand load paths — how gravity loads travel from the roof through walls and floors to the foundation — and be able to identify deficiencies in framing layouts. Calculation skills are required: at least a portion of the 172 exam skills involve numerical application of structural provisions.

Fire Separation Requirements for Residential Buildings

Fire protection represents 15% of the exam. Key competencies include understanding fire-resistance ratings for separations between dwelling units (typically 45 minutes for Part 9 buildings), limiting distances from property lines, and the requirements for smoke alarms and carbon monoxide detectors under Section 9.10 of the Code. The exam may present scenarios requiring you to determine whether a particular construction assembly meets the fire-resistance requirements or whether a building's exit arrangement complies with the Code.

The Guarantee Plan: Contractor Obligations

Unique to the 1.1.1 licence, the guarantee plan regulation is a cornerstone topic. Candidates must understand the three-tiered guarantee coverage (deposit protection, construction defect coverage, and major structural defect coverage), the administrator's inspection process, and the contractor's disclosure obligations. The exam tests practical application: given a scenario where a homeowner discovers a defect, you should be able to determine whether the guarantee applies, the applicable deadlines, and the contractor's obligations.

Building Envelope Performance in Quebec's Climate

Quebec's severe winters demand rigorous building envelope performance. The exam evaluates your understanding of the interplay between thermal insulation (minimum RSI values under Section 9.36), air barrier continuity, and vapour barrier placement. A common exam scenario involves determining the correct placement of the vapour barrier relative to the insulation to prevent condensation within the wall assembly. Candidates must also understand fenestration requirements, including energy ratings (ER values) for windows in different climate zones.

Legislative Framework and Contractor Classification

Module 1 alone accounts for 16% of the exam. Candidates must understand the hierarchical relationship between the Building Act, its regulations, and the Construction Code. Key topics include: conditions for obtaining and maintaining a licence, the role of the qualifier (répondant), the distinction between contractor subcategories, and the penalties for non-compliance. The exam expects you to navigate the Professional Qualifications Regulation to answer questions about licence conditions, financial guarantees, and the classification of contractors based on their volume of work.

7. Preparation Strategy and Tips for Success

The RBQ 1.1.1 exam covers 172 skills across 9 assessed modules — a broad scope that requires a structured study approach. Here is a recommended strategy:

Phase 1 — Master the closed-book documents first. The Building Act, the Safety Code for Construction Work, and the Sustainable Development Act must be memorized. Use Prof-RBQ.ca's AI-powered flashcards to systematically learn the key provisions, penalties, and principles from these three documents. This is where most candidates lose points — they focus on the Code but neglect the statutes they cannot reference during the exam.

Phase 2 — Learn to navigate the open-book documents efficiently. Having 3 documents on your desk during the exam is only useful if you can find answers quickly. Practice with the Professional Qualifications Regulation (know the article numbers for licence conditions), the Guarantee Plan Regulation (know the coverage structure), and especially the Construction Code (master the table of contents and cross-references in Part 9). Prof-RBQ.ca's quizzes are designed to build this navigation reflex.

Phase 3 — Prioritize high-weight modules. Modules 1, 3, and 6 together account for 80 of the 172 skills (47% of the exam). Focus your deepest study here. Module 4 (Structure) and Module 8 (Architectural Components) add another 40 skills (23%). These five modules combined represent 70% of the exam — mastering them gives you a strong foundation.

Phase 4 — Practice calculation questions. Several skills involve structural calculations (footing sizes, joist spans, fire-resistance ratings). Use Prof-RBQ.ca's practice exercises to build comfort with the span tables and calculation methods. On exam day, these questions take more time — allocate accordingly within your 180 minutes.

Phase 5 — Complete full timed simulations. Before the exam, do at least 2–3 full practice exams under timed conditions. This helps you calibrate your pacing: roughly 1 minute per question, with extra time reserved for calculation-heavy items.
