BuildZoom Alternative — Igni Permit Intelligence
Looking for a BuildZoom alternative for permit data? See how Igni approaches coverage, freshness and ADU/SB-9 typing — and what to verify first.
If you're considering BuildZoom and want to weigh another option for permit data, this page lays out the dimensions that matter when choosing a source and explains how Igni approaches each. BuildZoom is a recognized name in the construction and permits space; rather than assert its specifics — which change and which you should verify on their own site — we focus on how Igni works and what to look for in any permit-data source.
Igni specializes in ADU and residential permit intelligence: typed ADU classification, California SB-9/SB-10 flags, and sub-24-hour freshness, all sourced directly from official municipal open-data portals. 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.

A checklist for choosing a permit-data source
Comparing permit-data options comes down to a short checklist: sourcing (where the data originates and how verifiable it is), coverage (which markets, and how it grows), freshness (how soon a filing appears), classification (whether ADUs are typed or left as raw work descriptions), and delivery (dashboard, export, API, alerts). Pricing model matters but follows from fit.
Rather than state specifics about BuildZoom that may have changed, we give you the framework — apply it to BuildZoom and to Igni using each source's own current documentation.
How Igni approaches each dimension
Igni is purpose-built for ADU and residential permit intelligence. Sourcing is direct from official municipal open-data portals, normalized into one schema. Coverage is 60 cities across 37 US states and grows jurisdiction by jurisdiction. Freshness is sub-24-hour where the source supports it, ingested continuously.
Classification is the specialization: typed ADU classification 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 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.
If that's how you work, request access and tell us which cities and project types you focus on. For audience detail, see our pages for real-estate investors and lenders.
