BuildZoom Alternative — Igni Permit Intelligence
BuildZoom is known as a contractor-matching marketplace built on permit data. See how Igni's ADU-typed, forward-looking permit feed differs.
BuildZoom is widely recognized as an online marketplace that connects homeowners with contractors, backed by a large database of building permits it uses for contractor vetting and project research. If you came here looking for a permit-data feed rather than a hire-a-contractor service, it's worth understanding that distinction — and where Igni fits.
Igni isn't a contractor marketplace; it's a permit-data product specialized for ADU and residential intelligence — typed ADU classification, California SB-9/SB-10 flags, and sub-24-hour freshness, sourced directly from official municipal open-data portals. We describe how Igni works rather than asserting BuildZoom's current specifics, which you should verify on their own site. For the underlying mechanics, see our building-permit data guide.
Competitor details change. The comparison below is based on general, publicly available information and describes how Igni approaches each dimension — always verify a vendor's current specifics, pricing, and coverage on their official site before deciding.

What BuildZoom is known for
BuildZoom is generally known as a two-sided marketplace: it helps homeowners find and vet contractors for a project, and it leans on a large body of building-permit history to inform that matching and to let people research contractors and past work. In other words, its center of gravity is connecting people who want to build with the professionals who will do the work, with permit data as the backbone behind the scenes.
That's a different product from a permit-data feed. If your goal is to hire a contractor or look up a pro's permit history, a marketplace like BuildZoom is built for that. We're describing it in general terms because its exact features, coverage, and pricing change — verify the current specifics on their own site.
Marketplace vs permit-data feed
The key distinction is direction. A contractor marketplace is largely backward- and matchmaking-oriented: it uses historical permits to vet pros and connect homeowners to them. Igni is forward-looking and built for the opposite flow — surfacing fresh permit activity early so businesses can see where new projects are starting and reach owners while the project is still being scoped.
So the question isn't which is 'better' but which job you're hiring for. Want to find a contractor or research one's history? That's a marketplace. Want a current, ADU-typed stream of who's pulling residential and ADU permits in your markets, to drive your own outreach or market analysis? That's the lane Igni is built for. Our guide to getting construction leads explains why fresh permit signal matters for that use case.
How Igni approaches the data
Igni is purpose-built for ADU and residential permit intelligence. Sourcing is direct from official municipal open-data portals, normalized into one schema across 65 cities in 37 US states, and growing jurisdiction by jurisdiction. Freshness is sub-24-hour where the source supports it, ingested continuously rather than surfaced after the fact.
Classification is the specialization: typed ADU classification — detached, attached, junior, conversion, or unknown — plus California SB-9/SB-10 flags. Preview live activity in the permit dashboard, and see the typing explained in our ADU permit guide.
When Igni is the right fit
Igni fits best when you want a permit-data feed rather than a contractor marketplace — when your focus is ADUs and residential construction, you want California SB-9/SB-10 signal, and you prefer open-data sourcing you can verify. It's pre-revenue and contact-driven during the pilot, so getting started is a short conversation about your markets rather than a self-serve sign-up.
