OBC Small Buildings study plan

OBC Small Buildings · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Small Buildings: Part 9 Scope, Application and Construction Requirements & Building Classification, Occupancy and Construction Types

  • Map the Part 9 scope boundary by listing which building types, sizes and occupancies fall inside and outside it

  • Classify ten sample small buildings by major occupancy and construction type using the classification rules

  • Define the key terms that recur across the code and write plain-language versions of each

  • Identify which administrative requirements (permits, inspections, documents) attach to a small-building project

Your checkpoint

A one-page classification and scope decision tree covering at least ten worked examples with the governing rule cited for each

Week 2

Small Buildings: Part 9 Scope, Application and Construction Requirements & Structural Design and Load Requirements

  • Work through the Part 9 construction requirements for foundations, footings and crawl spaces

  • Compute dead, live, snow and wind loads for a simple low-rise building using the prescribed load values

  • Size sawn lumber members against span tables for floors and roofs

  • Check a set of structural details for compliance with the small-building prescriptive rules

Your checkpoint

A load-and-span worksheet for a single-storey building showing member sizes, spans and the load assumptions behind each choice

Week 3

Fire Protection, Occupant Safety and Life Safety Systems & Means of Egress and Exit Requirements

  • Determine required fire-resistance ratings and separations for a small building from its occupancy and construction

  • Lay out exit travel distances, exit widths and number of exits for three different floor plans

  • Specify smoke alarm, detection and suppression requirements for a residential occupancy

  • Verify stair, ramp, handrail and guard dimensions against the means-of-egress rules

Your checkpoint

Annotated floor plans for three occupancies showing exits, travel distances, ratings and life-safety devices with rule citations

Week 4

Fire Protection, Occupant Safety and Life Safety Systems & Means of Egress and Exit Requirements & General Provisions, Definitions and Administrative Requirements

  • Solve ten mixed life-safety and egress scenarios under time pressure

  • Reconcile conflicts between egress requirements and fire-protection requirements in a sample design

  • Explain how the administrative provisions affect when life-safety submissions are reviewed

  • Audit your weakest sub-topics from weeks 1 to 3 and rank them by error rate

Your checkpoint

A timed 40-question practice set scored by domain with a written error log identifying the top five recurring mistakes

Week 5

Health, Sanitation and Building Services & Energy Efficiency and Environmental Separation

  • Apply plumbing, ventilation and sanitation requirements to a small building layout

  • Determine thermal resistance, airtightness and vapour barrier requirements for walls, roofs and foundations

  • Locate the environmental separation and moisture-control provisions that govern envelope assemblies

  • Check lighting and natural ventilation adequacy for occupied rooms

Your checkpoint

A building-envelope and services checklist applied to one sample building, with each item marked compliant, deficient or not applicable

Week 6

Barrier-Free Accessibility Requirements & Energy Efficiency and Environmental Separation

  • Apply barrier-free path-of-travel requirements from parking and entry through to the occupied spaces

  • Dimension accessible washrooms, ramps, doors and turning spaces correctly

  • Identify where accessibility requirements conflict with exiting or structural constraints and how to resolve them

  • Integrate energy-efficiency requirements with accessibility detailing at doors and glazing

Your checkpoint

An accessibility audit of a sample floor plan listing every deficiency with the required correction and the governing provision

Week 7

General Provisions, Definitions and Administrative Requirements & Building Classification, Occupancy and Construction Types & Structural Design and Load Requirements

  • Revisit definitions and administrative provisions and close gaps flagged in the week 4 error log

  • Re-classify complex mixed-occupancy examples and justify each construction-type choice

  • Re-solve structural load and span problems at exam pace

  • Build a personal summary sheet of the highest-risk rules across these domains

Your checkpoint

A two-page condensed reference sheet plus a 30-question re-test on domains 1, 2 and 5 with a score of at least 80 percent

Week 8

Small Buildings: Part 9 Scope, Application and Construction Requirements & Fire Protection, Occupant Safety and Life Safety Systems & Means of Egress and Exit Requirements

  • Complete two full-length timed mock exams under exam conditions

  • Review every missed question and trace it back to the specific provision

  • Drill the heaviest domains until accuracy is consistent across repeated attempts

  • Confirm exam-day logistics, reference materials and time-allocation strategy

Your checkpoint

Two scored mock exams with a written remediation summary showing improvement between attempts and a final one-page exam-day plan

Milestones

Week 2: Can classify any small building by occupancy and construction type and size structural members from span tables without notes

Week 4: Scores at least 70 percent on the timed mixed life-safety and egress set, with an error log identifying the top five recurring mistakes

Week 6: Completes the accessibility and envelope audits with no missed deficiencies when checked against the answer key

Week 8: Scores at least 80 percent on both full-length mock exams, with the second attempt higher than the first
