Jobsite services: the permit tells you a construction site is about to exist
Alex Wilkinson
CEO of Houski
2026-07-15
If you rent bins, fencing, portable toilets, scaffolding, or equipment, or you sell site security, traffic control, or post-construction cleaning, your customer is not a building. Your customer is a construction site, a thing that exists for a few months at an address and then disappears. The whole game is knowing where sites are about to appear, and the permit record is that knowledge, published weeks before the first truck arrives.
We wrote separately about permits as a lead source for building material suppliers. Site services are a different sale with the same trigger, and in some ways a better one: materials get spec'd by the builder, but the bin, the fence, and the toilet get ordered by whoever picks up the phone first, usually on price and availability. Being first is most of the win, and the permit feed is how you are first.
The pull
Houski carries building permits for more than 80 cities, counties and states across the United States and Canada, for whole countries such as France, Poland, Finland and South Korea, and for cities and regions across Europe, attached to property records. One query returns every property in a city with recent building permit applications:

A city the size of Toronto files thousands of these a year. Every one is an address where a site either exists now or will soon, and every one arrives with the property's own details on the same row.
Reading the permit like a site services quote
The expand_permit_content field carries what the source city publishes, and three parts of it map directly onto what you rent or sell:
Status is your timing. An application still in review is a lead for next month's route planning. An issued permit is a site going active, which is fence and toilet territory. The content carries status and issue dates, so "sort by recently issued" is your hottest list, refreshed weekly.
Estimated project cost is your site size. Where the permit states it, expand_permit_value carries the declared value of the whole job as a number, and it is a solid proxy for how long the site lives and how much it needs. A twenty-thousand-dollar alteration is one bin for two weeks. A seven-figure project is months of fencing, multiple swaps, security worth quoting, and a cleanup contract at the end. Price your outreach effort against the number in the record.
Work class is your product fit. A demolition means bins immediately and dust control. A new build means the full sequence from fence to final clean. An interior alteration might mean a single bin and nothing else. The class tells you which trucks the address will ever need, before anyone calls.
One mechanical note: the API filters on permit type, date and value, and it can match a pattern against the content with expand_permit_content_regex. Status and class live in the content field, so pulling them out cleanly happens in your code after the pull. The content is labelled text, laid out a little differently by each city, so this is a parsing afternoon, not a data science hire.
The end of the site is also a sale
Everyone chases the start of a project. The completion is a lead too: completed permits mean post-construction cleaning, final bin pulls, landscaping repair where the machines tracked through, and a homeowner or builder who just stopped needing a fence you might currently be renting to a competitor. Where the content carries completion dates, you can run the same bot in reverse: a list of sites that just finished, for the services that begin when construction ends.
Route density is the quiet advantage
Site services live and die on drive time. Because every permit is attached to a property with a community on the row, the week's new permits group by neighbourhood for free. Three new sites in one community is not three leads, it is one efficient route, and that is a quoting advantage over whoever prices every job as a one-off drive across town. Pull the feed weekly, cluster by community, and let the map decide which leads are worth a sharper price.
For the plumbing of a weekly pull (deduplication, filtering, posting to your team's channel) the permit alert bot walkthrough applies to this business without modification.
Honest limits
Only where permits are published. A place with no published permits returns nothing.
Not every permit becomes a site. Applications get refused and cancelled, and the status in the content says so. Filter before anyone drives anywhere.
Content detail varies by city. Project cost and work class are present where the city publishes them, which is not everywhere. Build the parser to treat every labelled segment as optional.
Big general contractors have standing suppliers. The permit feed will not win you a national builder's fence contract. It shines on the long tail (custom builds, renovations, small commercial) where the ordering decision happens per-project and late.
Getting started
- Sign up for API access
- Pull this month's building permits for your city with the query above
- Parse status, cost, and class out of the content
- Cluster by community and hand each route's list to whoever quotes
- Track close rate by permit class and tune the filter to what actually rents
Most fields cost a tenth of a cent per field per property, so a weekly pull for one city typically runs a few dollars or less. Details on the pricing page and the expand documentation.
