About Igni

What we do

Every day, cities and counties across the United States publish the building permits they issue and receive. That record is a leading indicator of construction demand — but it is scattered across dozens of municipal open-data portals, each with its own format, schedule and quirks. Igni collects those feeds, normalizes them into one consistent shape, classifies the work type (with a focus on ADUs), and surfaces the result as timely, filterable leads.

We currently track building-permit activity across 37 US states and 65 cities, refreshed continuously so a new permit can reach a subscriber in under a day. For each permit we add structure that the raw record often lacks: whether it looks like an ADU and what kind, an estimate of California SB-9 / SB-10 relevance where applicable, and a resolved ZIP when the source feed omits one.

Who we build for

Igni is built for the people who act on early construction signals: ADU and residential builders and contractors looking for projects in their service area, and lenders and financing providers who want to reach owners at the point a permit is filed. The common thread is timing — the value of a permit signal decays quickly, so freshness and accurate work-type classification matter more than volume.

Our data-driven approach

We are deliberately a data company, not a data reseller. Every source we use is an official government open-data feed, reviewed for its terms of use and license before we connect to it, and we honor each source's attribution requirements where they exist. We do not scrape behind logins, and we treat the underlying records as what they are: public information that anyone is entitled to read.

Because the raw feeds are messy, most of our work is in the seams — reconciling addresses, recovering missing ZIP codes, deduping permits that straddle jurisdiction boundaries, and distinguishing a real accessory dwelling unit from a shed or a re-roof. Our methodology page documents exactly how the pipeline sources, classifies, refreshes and licenses the data.

Igni Research

Our guides, comparisons and glossary are written and maintained by Igni Research, our in-house editorial and data team. We write from the same public records and primary sources we work with every day, link to the official housing statutes and permitting authorities, and date every article so you can see when it was last reviewed. Permitting and housing law change often and vary by jurisdiction, so we treat our content as a starting point for your own due diligence, not a substitute for it.

Our mission

More housing gets built when the people who can build and finance it find the right projects sooner. Public permit records already contain that signal; it is just hard to use. Our mission is to make that public data genuinely usable — fresh, accurate, properly attributed, and honest about its limits — so the residential and ADU market can move faster on real demand.
