PermitCore vs ATTOM — different scope, compared honestly.
ATTOM is one of the largest property-data warehouses — assessor, deed, mortgage, AVM, and building permits across 160M+ U.S. properties, linked by a single ATTOM ID. Building permits are one slice of that warehouse. PermitCore goes the other way: permit-specific depth for commercial construction — segment classification, manufacturer-brand detection, sales framing. Below: ATTOM's real strengths named plainly, our axes substantiated, and when each is the better choice. Every ATTOM claim cites a public source and the dated scan that verified it.

A property-data warehouse vs permit-specific intelligence.
ATTOM is broad (every property-data type, linked). PermitCore is deep on one (commercial-construction permits + brand detection). Each cell on ATTOM's side cites a public source and the date of the scan that verified it. Claims without a dated source don't appear.
| Axis | PermitCore | ATTOM |

| Scope | Permit-specific commercial-construction sales intelligence Shipped: how the pipeline works, permit-first rather than property-first. | Broad property-data warehouse — assessor, deed, mortgage, AVM, foreclosure, environmental + permits, linked by one ATTOM ID Source: ATTOM published materials (attomdata.com); verified 2026-06-28 scan. See sourcing note ↓ |
| Property / permit breadth | 35 US metros (curated commercial footprint) Shipped: the coverage table, every metro with its own permit count. | 160M+ properties / 99% of US population; 335M+ permit records across 3,144 counties Source: ATTOM published materials + ATTOM data listings; verified 2026-06-28 scan. |
| Permit refresh cadence | Nightly (24–48h from source-portal publish) Shipped: per-metro freshness, dated on the row rather than claimed in aggregate. | Building-permit data updated monthly Source: ATTOM published materials; verified 2026-06-28 scan. |
| Self-serve pricing | $89/mo Pro tier, self-serve Stripe checkout, no sales call — public flat price Shipped: pricing, with the checkout on the page. | No public flat price — yearly license / custom Source: ATTOM published materials / data listings; verified 2026-06-28 scan. ATTOM publishes no flat self-serve price. |
| Manufacturer / brand detection | Yes — manufacturer brands detected in permit text (≥99% precision): /brands directory, a permit-page brand chip, and a Market Explorer brand filter Shipped: the brand directory, plus a chip on every permit that names one. | No brand-detection surface found in public materials (ATTOM carries permit classifiers, but not manufacturer/brand identification) Source: absence across ATTOM's public permit materials as of 2026-06-28 scan. |
| Commercial segment classification | 9 commercial IBC segments — every permit lands in exactly one Shipped: the segment index, each browsable with its own permits. | Detailed permit classifiers (permit categories); no published commercial-IBC segment taxonomy Source: ATTOM published materials; verified 2026-06-28 scan. |

When ATTOM is the right call for your team.
ATTOM and PermitCore solve different problems. Here's when ATTOM is genuinely the better choice — stated plainly.
Broad, linked property data
If you need assessor, deed, mortgage, AVM, and risk data linked to a property (not just permits) at national scale — underwriting, valuation, portfolio risk — ATTOM's warehouse is built for that. PermitCore is permit-specific and doesn't carry those data types. Source: ATTOM published materials; verified 2026-06-28 scan.
Near-total US property coverage
If your workflow needs 99%-of-US-population property coverage across 3,000+ counties, ATTOM's footprint is structurally ahead of PermitCore's curated 35-metro commercial footprint. Source: ATTOM published materials; verified 2026-06-28 scan.
Warehouse / bulk / cloud data ops
If you license bulk property data into a warehouse or consume AI-ready datasets at enterprise scale, ATTOM's bulk + cloud-delivery motion serves that. PermitCore delivers via API + the free in-browser Market Explorer. Source: ATTOM published materials; verified 2026-06-28 scan.
When PermitCore is the right call for your team.
Fresh permit signal (nightly vs monthly)
If permit recency drives your workflow — same-week territory planning or lead enrichment — PermitCore's nightly rebuild is ahead of ATTOM's monthly permit refresh. Source: ATTOM published materials (monthly permit cadence); verified 2026-06-28 scan.
Manufacturer / brand replacement-targeting
If you want to find where a specific manufacturer's equipment was installed, PermitCore detects manufacturer brands named in permit text (≥99% precision). ATTOM carries permit classifiers but no brand-detection surface in its public materials.
Commercial-segment go-to-market
If you sell building products into commercial construction, PermitCore's 9 commercial IBC segments map to your buyer questions — every permit classified into exactly one. ATTOM's permit classifiers aren't a commercial-segment taxonomy.
Transparent, self-serve evaluation
If you want a public price and to evaluate the API before paying — sign up, get a key, query in 60 seconds — PermitCore's $89/mo Pro tier is self-serve with no sales call, and the Market Explorer is free in-browser. ATTOM is yearly-license / custom.
Sourcing + methodology.
Every ATTOM claim on this page cites a public source — ATTOM's product site (attomdata.com), its public data listings, and its press releases — and the date of the competitive scan that verified it.
One sourcing note for transparency: ATTOM's building-permit page returned a rate-limit response (HTTP 429) to our automated fetch on the 2026-06-28 scan. So its figures (160M+ properties, 335M+ permits, 3,144 counties, monthly cadence) are attributed to ATTOM's published materials — its site as quoted in public listings and press — rather than a byte-for-byte fetch we performed this pass. We flag the sourcing rather than imply verification we couldn't do.
This page is last reviewed: June 2026 (scan date 2026-06-28). On the next scheduled scan, every cell is re-verified or removed. A comparison page with a stale date is a lie with a timestamp.
Frequently asked about PermitCore vs ATTOM.
- Is ATTOM a permit-data company?
- ATTOM is a broad property-data warehouse — assessor, deed, mortgage, AVM, foreclosure, environmental risk, and building permits, all linked by a unique ATTOM ID across 160M+ U.S. properties (per ATTOM's published materials, 2026-06-28 scan). Building permits are one of many data types it carries. PermitCore is permit-specific: we go deep on commercial-construction permits — segment classification, manufacturer-brand detection, sales framing — rather than wide across every property-data type. Different scope.
- Whose permit data is fresher?
- For permits specifically, PermitCore is fresher, and it's sourced: ATTOM's building-permit data is updated monthly (per ATTOM's published materials, 2026-06-28 scan), while PermitCore rebuilds nightly (24–48h from source-portal publish). If permit recency drives your workflow — same-week territory or lead enrichment — nightly beats monthly. ATTOM's strength is the breadth of linked property data, not permit-refresh speed.
- Does ATTOM detect manufacturer brands in permits like PermitCore?
- ATTOM carries detailed permit classifiers (permit categories), but we have not found a manufacturer/brand-detection surface in ATTOM's public materials as of our 2026-06-28 scan. PermitCore detects the manufacturer brand named in the permit text at ≥99% precision (the /brands directory, a permit-page brand chip, and a Market Explorer brand filter). For brand-level replacement targeting, that's our specific surface.
- How current is this comparison?
- Last reviewed June 2026 (visible at the top). Every ATTOM claim cites its public source and the 2026-06-28 scan date. ATTOM's permit page returned a rate-limit (HTTP 429) to our automated fetch on that scan, so its figures are attributed to ATTOM's published materials (attomdata.com, its data listings, and press releases) rather than a byte-for-byte fetch — we flag that rather than overclaim. Next re-verification: our next quarterly scan.
