The square footage trap: why Applejack listings disagree with the tape measure

How this happens

Nobody is lying. The problem is that “square footage” on a listing can come from at least five different sources - assessment records, builder plans, professional interior measurement, professional exterior measurement, or simply whatever the seller’s side provided - and they measure different things. The biggest gap is the lower level: on Victoria Street, finished walk-out lower levels are standard, and whether that space counts as “above grade,” gets counted separately, or gets counted at all varies source to source.

In the pair above, one listing had effectively counted the walk-out level as above-grade space. Result: a unit that measures about 760 square feet on the main floor was advertised at 1,350. Add the finished lower level and the true total is about 1,475 - so the “wrong” number was not even generous, it was just differently wrong than the neighbour’s.

The part almost nobody knows: the rulebooks themselves disagreed

Here is the piece of this story I can tell you from inside the industry. It is not just that measurement sources differ - for years, the rulebooks the listings were written under disagreed with each other.

Real estate listings go into regional board systems, and each board historically set its own rules. Toronto’s board - TRREB, the country’s biggest - says the square footage on a listing counts above-grade space only. The basement never counts in the headline number; finished lower-level space is disclosed separately. The former Southern Georgian Bay board, which covered this area, allowed all finished square footage in the number. Same unit, honestly entered both places, two very different “sizes.”

Bedrooms worked the same way. A walk-out home the local board called a four-bedroom is a “3+1” under Toronto rules - three above grade, one below. Neither is wrong. They are answers to different questions.

Then, a little over a year ago as I write this, the boards began integrating their data, and everything had to start aligning with Toronto’s standards. Most current listings now follow the TRREB convention, because they publish to both the local system and Toronto’s. But older listings - the ones you find when you research past sales - carry whichever rulebook they were entered under. A 2022 local listing and a 2026 listing of the very same unit can disagree by an entire finished basement, and both were entered correctly.

And one mystery solved for free: if you ever noticed what looked like duplicate listings on realtor.ca - same property, slightly different size, different bedroom count - this is where that came from. One listing per board, two rulebooks, one confused public. You were not imagining it.

The payoff: the market is smarter than the listings

Measure everything the same way and the apparent chaos in Applejack pricing largely evaporates. Two near-identical homes, wildly different advertised sizes, essentially identical sale prices: buyers standing in the units priced the actual space, not the listing’s number. The market got it right on its feet.

That should genuinely reassure you. It also means the published price-per-square-foot on any Applejack sale is close to meaningless unless you know the measurement standard behind it.

The rules I follow, and you should too

• Ask the source of every square footage number. “Measured” or a professional floor plan beats everything else. Assessment records and “provided” figures are starting points, not facts.
• Think in total finished area in a community where walk-out lower levels are standard. “Above grade” alone systematically understates what Victoria Street units live like.
• Never compare price per square foot across two listings unless both numbers come from the same kind of source. You would be dividing by two different rulers.
• Mind the listing’s vintage. Older local listings may report all finished space under the former board’s rules; current ones follow Toronto’s above-grade standard. Same unit, two eras, two different “sizes” - and the same goes for bedroom counts. When you compare a past sale to a current listing, check which rulebook each number was born under.
• When it matters, measure. A professional floor plan costs little against a purchase this size, and it is the number a future buyer will trust when you sell.

Any square footage figure here states its source, and where I hold a professional plan I use it. It is the same standard I would want as the buyer.
