- It is a tracker of current active MLS® inventory we've classified as carrying a legal or illegal secondary suite, plus links to CREB®'s official monthly Calgary statistics for broader context.
- It is not a legal-suite sales series — CREB® does not publish sales statistics segmented by legal-suite status.
- Individual listing sale, close or list prices are not included in the aggregate tables below.
- Q3 2026 is not complete at the time of this report; treat the snapshot as an opening reading.
1. Current inventory snapshot
Live count of active MLS® listings in Calgary classified by LegalSuites.ca's DDF® parser. Sample threshold for any published breakdown: at least 10 listings.
| Classification | Active listings |
|---|---|
| Legal secondary suite | 67 |
| Illegal / non-conforming suite | 27 |
| Unclassified (review needed) | 106 |
| No suite indicated | 800 |
| Total active Calgary listings | 1,000 |
2. Quadrant distribution
| Quadrant | Legal | Illegal / non-conforming |
|---|---|---|
| Northwest | 21 | 4 |
| Northeast | 17 | 14 |
| Southwest | 16 | 5 |
| Southeast | 12 | 4 |
3. Year-built distribution (legal suites only)
| Bucket | Active legal-suite listings |
|---|---|
| 2024+ | 25 |
| 2020–2023 | 11 |
| Pre-2010 | 27 |
Rows below the 10-listing sample threshold are suppressed.
4. Broad price bands (legal suites only, counts)
| List-price band | Active legal-suite listings |
|---|---|
| $500k–$700k | 24 |
| $700k–$900k | 22 |
| $900k–$1.2M | 10 |
| Over $1.2M | 11 |
Bands are counts of active listings, not prices paid. Individual list prices appear on listing detail pages, not in this aggregate report.
5. Broader Calgary context (CREB®)
CREB® publishes Calgary-wide monthly and quarterly housing statistics that are not segmented by legal-suite status. Read them alongside this tracker for context on the broader resale market, especially row-home and detached activity:
- CREB® housing statistics hub
- CREB® June 2026 monthly release — closes out the Q2 2026 context above.
6. Methodology & sources
- Universe: active MLS® listings in the City of Calgary, sourced from the CREA DDF® feed.
- Classification: each listing is parsed against structured DDF® fields and remarks to determine suite status; see the editorial policy.
- Sample threshold: a minimum of 10 listings is required before a breakdown row is published.
- Refresh cadence: DDF® syncs roughly every 6 hours; this page re-computes on load.
- Not published: individual list, sale or close prices in aggregate tables; sold-price series (CREB® does not aggregate by legal-suite status); rent, ROI or cashflow estimates.
- Verification: the City of Calgary secondary suites page and its Secondary Suite Registry are the authoritative source for suite status on any specific property.
DDF® listing remarks are written by many different brokerages and can misuse "legal" or omit suite status entirely. Our parser therefore under-counts and mis-classifies at the edges. Treat this tracker as an inventory signal — not a legal record.
