House 2024, Part 9
The exam the 2024 code changed most. Practice built on the new one.
170 verified Part 9 questions written against the 2024 compendium, with the exact article printed under every answer. Old banks still point at articles that no longer exist.
A basement apartment is created in a detached home so that the building, which is entirely residential, contains two self-contained dwelling units plus a shared laundry area, all held as a single real estate entity. Which Division A defined term specifically describes the added basement unit?
- House
- Duplex
- Boarding, lodging or rooming house
- Secondary suite
Why D. The scenario matches every element of the definition: a self-contained dwelling unit in a building of only residential occupancy containing one other dwelling unit and common spaces, forming a single real estate entity. Option A fails because "house" was deleted as a defined term in the 2024 code. That deletion is the single most common thing 2012 era study material still gets wrong.
2024 OBC Div. A, 1.4.1.2.Part 9 is where the 2024 changeover actually bites.
Every exam since 30 March 2026 runs on the 2024 code. On the House exam, that is not a formality. It moves the answers.
The definition you were taught is gone
"House" is no longer a defined term. "Secondary suite" is, and Part 9 now says things like "a house with a secondary suite" instead. A candidate hunting Division A for the old definition loses time and then picks a distractor built from it.
The numbers moved, including the ones you memorised
Framing spacings went from 305, 406 and 610 mm to 300, 400 and 600. A new sentence allows 1 850 mm clear height over a secondary suite stair under a duct. A 150 mm sphere rule now governs the riser and tread triangle. Old habits score zero.

How the program gets you to 70%
Open book means the exam scores navigation. So the practice trains navigation.
Learn where things live
Practice by topic with instant feedback. Every answer prints its article, so each question trains the reflex of landing on the right page the first time.
Drill what changed in 2024
Secondary suites, the open riser restriction, guard opening rules, soft metric framing and the renumbering itself. This is the content 2012 era material gets wrong.
Sit two complete papers
Two full papers, Red and Blue, each 70 questions against a three hour clock with flagging, a navigator grid and auto submit. Each is weighted across every syllabus topic, not drawn at random, so neither paper leaves out an area. The bank behind them covers the published syllabus section by section. Results break down by topic.
How every question gets verified, and what changed in the 2024 code.

Questions people ask before buying
Other banks have more questions, and some cost less. Why this one?
Some banks are bigger and some are cheaper, and if volume is what you are buying, buy those. What you get here is a bank where every answer prints the exact 2024 article it came from, so working a question also teaches you where that rule sits in the compendium you'll carry into the exam. Every question was written from located source text, then re-checked independently before it shipped. You don't have to take that on faith either: the free 12 question sample draws on this bank, so you can judge our wording and our citations before you pay for any of it. There is no subscription and nothing to renew, so nothing you buy here sits on a clock.
Do I need General Legal/Process before House?
Most candidates sit General Legal/Process first because it is the universal qualification exam, then add House as their technical category. They are separate examinations and you can sit them in either order. The exam selection guide covers the combinations.
Is the bank big enough to prepare me?
The exam is 70 questions, open book, and what it really scores is how fast you land on the right article. Here is the arithmetic, so you can judge it yourself. This bank holds 170 questions covering all 23 syllabus topics. Two full 70 question simulations with no repeats need 140, so you can sit two complete papers back to back without seeing a question twice, and still have the whole bank for topic drilling. It will not get you through by memorising, and it is not built to. The free 12 question quiz draws on the same bank, so you can judge the questions before you spend anything.
How do I know the answers are right?
Check them. The article is printed under every answer, so you can verify against your own compendium in seconds. Behind that, every question was written from the source text and independently re-checked before publishing. Every question also carries a report button, and a confirmed error is corrected in the next bank update.
Do I get updates, and does access expire?
Your licence has no expiry, there is no subscription and nothing to renew, and every addition to this bank through the 2024 code cycle is free. Two things are worth knowing. Access runs through this site, so activating another device needs the site to be there. And your progress lives in your browser, so clearing site data or moving to a different device starts the progress count over, although the key itself keeps working.
Practise on the code you will actually be handed.
$129 once, against $150 every time you sit it again.
