Construction Monitor Alternative — Igni
Construction Monitor is a long-established provider of nationwide permit data and lead lists. See how Igni's ADU-typed, open-data feed differs.
Construction Monitor is a long-established name in building-permit data, known for delivering nationwide permit information and lead lists to suppliers, lenders, and contractors across all kinds of construction. If you're weighing it against a more specialized option, this page explains where Igni concentrates and how the two differ in approach.
Igni isn't a broad, all-construction permit service; it's narrowly focused on 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 Construction Monitor's current specifics, which you should verify on their own site. For background, 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 Construction Monitor is known for
Construction Monitor is generally known as one of the longer-running providers of building-permit data, associated with broad nationwide coverage and with packaging permit information into lead lists and reports for suppliers, lenders, building-product manufacturers, and contractors. Its strength is breadth across all construction types — residential, commercial, and beyond — delivered as a recurring stream of permit activity.
That breadth is the main contrast with Igni. A broad, all-construction permit service casts a wide net; Igni deliberately casts a narrow one. We're describing Construction Monitor in general terms because its exact coverage, delivery, and pricing change — verify the current specifics on their own site before deciding.
Broad permit data vs ADU-typed intelligence
The trade-off here is breadth versus depth in a specific niche. A broad service aims to cover as much construction as possible across markets and project types. Igni instead goes deep on accessory dwelling units and residential work: it applies a typed ADU classification — detached, attached, junior, conversion, or unknown — and carries California SB-9/SB-10 flags, so you can filter to exactly the accessory-unit activity that matters without reading raw work descriptions.
That makes the decision a matter of fit. If you need wide coverage across all construction types, a broad provider is built for that. If your business lives in the ADU and residential space and you want that typing and California signal done for you, that's the gap Igni fills. For how that signal turns into outreach, see our guide to getting construction leads.
How to compare the two
Judge both on the same concrete dimensions: sourcing (where the data comes from and how verifiable it is), coverage (which markets and project types, and how they expand), freshness (how quickly a filing appears), classification (whether ADUs are typed or left as raw text), and delivery (dashboard, export, API, alerts, or lists). Igni's answer to sourcing is that every record traces back to an official municipal open-data portal, normalized into one schema across 65 cities in 37 US states, with sub-24-hour freshness where the source supports it.
Apply the same checklist to Construction Monitor using their current documentation rather than relying on any third-party summary. You can preview Igni's live activity in the permit dashboard and see the typing explained in our ADU permit guide.
When Igni is the right fit
Igni is the right fit when your work centers on ADUs and residential construction specifically — not all construction — and you want California SB-9/SB-10 signal plus open-data sourcing you can verify. It's pre-revenue and contact-driven during the pilot, so starting is a short conversation about your markets rather than a self-serve checkout.
If that's how you work, request access and tell us which cities and project types you focus on. For audience-specific detail, see our pages for ADU suppliers and general contractors.
