Buyer & seller research
In the upper price ranges, the renovation story is often the largest part of the value story — and the least documented. Whether you are buying or selling, the objective is the same: convert claims into evidence, and be honest about what the evidence does not settle.
Key takeaways
Sources: City of Calgary permits hub and home improvement permit types. Checked July 29, 2026.
Whether a specific project required a permit — and which type — depends on its scope and on the rules applying at the time. Treat the list as the set of areas to investigate, not as a determination. The City is the authority on any individual property or file.
Build one row per claimed improvement. A luxury home with three significant renovation phases should produce three complete rows, not one summary line.
| Column | What good evidence looks like |
|---|---|
| Improvement claimed | Exactly what is being represented — e.g. full main-floor reconfiguration, not "renovated". |
| Approximate date | Year and season if known; effective age matters more than the listing adjective. |
| Drawings / specifications | Architectural, structural or interior drawings, finish schedules, engineered details. |
| Development permit | Where land-use, form or siting was affected — additions, secondary suites, some accessory structures. |
| Building permit | Where structure, occupancy or life-safety was affected. |
| Trade permits | Plumbing, electrical, gas and HVAC work is typically permitted separately from the building permit. |
| Final inspections | Whether each permit reached a completed status, not merely an issued one. |
| Invoices and warranties | Contractor invoices, product warranties, membrane and roofing warranties, mechanical commissioning reports. |
| Designer / engineer / contractor | Named parties, so the work can be discussed with someone who did it. |
| Observed condition | What an experienced eye and an inspector actually see today. |
| Specialist follow-up | Who needs to look further: inspector, structural engineer, lawyer, or the City. |
The City publishes permit and property research tools that let you look up records associated with an address. Use them to build questions, and read the results carefully: record-keeping practices, project scopes and system coverage change over time, so a gap may mean the work needed no permit, was recorded differently, or predates a system — as well as the less comfortable possibilities.
A certificate of title from Alberta Land Titles is a separate and complementary check: it records registered interests such as mortgages, caveats, easements, restrictive covenants and utility rights of way that can constrain what has been built or what may yet be built. A title search is not a survey, an inspection or a legal opinion.
Nothing on this page is legal advice or a compliance determination. Conditions and timelines in an Alberta contract should be drafted with your lawyer and your REALTOR®.
