Building material suppliers: a permit application is a customer announcing themselves
Alex Wilkinson
CEO of Houski
2026-07-15
Somebody who pulls a building permit is about to spend money on materials. Not "considering a project someday." The drawings are done, the application fee is paid, and in a few weeks a truck is going to deliver lumber, concrete, drywall, windows, or roofing to that address. The only open question is whose truck.
Most suppliers find out about projects when the buyer walks in. The permit record exists weeks earlier, it is attached to a specific address, and it frequently says what the project is, what it is estimated to cost, and who is running it.
Houski carries building permits for Calgary, Edmonton, Toronto, and Vancouver, attached to the property record so the permit and the property details come back in one query.
The volume is real
Counting properties with a permit application filed since January 1 of this year: Toronto has 19,579, Calgary has 8,300, Vancouver has 4,605, and Edmonton has 3,653. That is roughly 36,000 addresses across four cities where a project is in motion right now, and the year is only half over.
Nobody can visit 35,000 addresses. But a distributor can absolutely rank them, territory them, and put the top slice in front of an outside sales team every Monday morning.
Pulling the active projects
Add expand=permits to a property query and filter on the application date:

That is 5,815 Calgary properties with a building permit application filed this year. Each row gives you the property itself plus the permit records attached to it.
The interesting part is expand_permit_content. It is a text field and its exact format varies by city, but for a Calgary building permit it typically carries the status, the work class, the estimated project cost, the square footage affected, and the applicant. A retaining wall alteration with an estimated project cost of 1.2 million dollars reads very differently from a basement development at forty thousand, and you can route them to different reps, or different product lines, accordingly.
Three permit types, three different sales motions
The expand_permit_type field is deliberately coarse. It has three values, and each one is a different kind of lead.
Building is the direct one. Construction or renovation is approved or in review at this address. This is the materials sale, and the application date tells you where they are in the timeline. A permit filed last week is a project still sourcing. A permit filed in January is probably framed by now, which moves the conversation from lumber to finishes.
Development is the early signal. A development permit precedes the building permit, sometimes by many months. This one is filed while the project is still on paper, which is exactly when a supplier who shows up with pricing gets designed in rather than shopped afterward.

2,069 Calgary properties this year sit at that earlier stage.
Business license is the fit-out lead. A new business licensing a premises usually means renovation of that premises - flooring, lighting, millwork, signage, paint. If you sell to commercial trades, a fresh license at a commercial address is a project that has not hit the building permit stage yet.
The applicant is often the better lead than the address
On a lot of permits, the applicant named in the content is not the homeowner. It is a contractor or a builder. For a supplier, that is not a problem, that is the actual prize. A homeowner buys materials once. A contractor who shows up on nine permits this quarter buys materials every week, and the permit data just told you who is busy in your delivery area and what kind of work they are doing.
Group the permit content by applicant and you have a ranked list of the most active accounts you do not have yet.
What this data will not do
It covers four cities. Calgary, Edmonton, Toronto, Vancouver. Outside those, no permit records, and a query filtered on permits returns nothing. Coverage by permit type also varies - Vancouver, for instance, carries building permits and business licenses but no separate development permit stream - so check your city and type before you build the workflow around it.
The content format is not uniform. Each city structures its permit text differently. Estimated project cost shows up on Calgary building permits, but do not assume every record everywhere has it. Build your parsing to degrade gracefully.
A permit is not a purchase order. Some applications get cancelled or refused, and the status field in the content says so. Filter those out before anyone drives anywhere.
Timing is approximate. The application date is a fact. When the drywall order lands is an inference. Treat the data as a prioritized call list, not a delivery schedule.
The pre-built version
The datasets page has Recent renovation or addition permits and Recent demolition permits already assembled, and Building supply distribution is built for exactly this use case. Each updates daily.
If you want it shaped to your business - your delivery radius, your product categories mapped to work classes, applicants deduplicated and ranked by permit count - our data team builds custom datasets on your schedule. Ask for one.
Getting started
- Sign up for API access
- Pull last month's permits for your city with the query above
- Sort by what the content tells you - project cost, work class, applicant
- Hand your reps the top fifty and measure what a permit-sourced lead closes at versus a walk-in
- Repeat weekly - the list refreshes as new applications land
Most fields cost a tenth of a cent per field per property, so a full month of permit-active addresses in your city with property details attached costs a few dollars. Details on the pricing page and the expand documentation.
The permit does not tell you what to quote. It tells you which addresses have a project underway and who is running it, which is the part of the sale you cannot get from anyone who walks in the door. Explore the API or browse the datasets.
