Comparing Shovels.ai, BuildZoom, and ConstructionMonitor side by side: coverage, pricing, use cases, and who each is built for. Plus where Permit Ledger fits.
If you've been researching building permit data, you've probably run into the same three or four names: Shovels, BuildZoom, ConstructionMonitor, and, if you're a renovation contractor, Permit Ledger. They all deal in permit data, but they're built for very different buyers. Here's a clear-eyed breakdown of who each one is actually for.

Shovels.ai
Shovels is an API-first permit data platform built for software developers and data-driven companies. Their national dataset is well-structured, the API documentation is genuinely good, and they've invested in data enrichment, including pre-permit signals and contractor contact information. For an engineering team building a product on top of permit data, Shovels is probably the best-documented option available.
The trade-off: Shovels is not built for contractors. There's no 'email me a list of this week's roofers' workflow. Data arrives via API, which means you need technical resources to consume it. The renovation-only filter doesn't exist out of the box, you get all permit types and write your own logic. Plans start around $300/month with volume-based pricing above that.
Best for: Development teams building permit data into a product or internal tool. Not practical for a contractor looking for a weekly lead list.
BuildZoom
BuildZoom started as a contractor marketplace and evolved into a data platform. Its most distinctive feature is the ability to look up any licensed contractor's permit history, how many projects they've completed, in which categories, and over what time frame. That makes BuildZoom uniquely useful for architects and developers who need to vet subcontractors.
BuildZoom also sells permit data products, project lookup by address, historical permit records, and API access. Coverage is national and historical depth goes back 25+ years. But the pricing reflects an enterprise audience: most meaningful data plans run $500–$2,000+/month on annual contracts.
For a local renovation contractor looking for leads in their market, BuildZoom is overbuilt and overpriced. It's designed for companies that need nationwide data or contractor vetting, not for a roofing crew that wants this week's permit filings in Columbus. See our BuildZoom comparison for the full head-to-head.
Best for: General contractors, architects, developers, and enterprise buyers who need contractor history data or national project lookups.
ConstructionMonitor
ConstructionMonitor has been in the construction data business since the early 1990s, they predate the modern open data movement and built their business on physical permit report mailings before transitioning to digital. Their core product is a subscription that delivers new permit filings for your target market on a regular basis.
Their strength is breadth: national coverage, deep historical records, and established relationships with jurisdictions that other providers haven't tapped. Their weakness for renovation contractors is focus: ConstructionMonitor's data skews toward new construction and commercial activity. The filtering tools for residential renovation specifically are less refined than what a dedicated renovation data service offers.
Pricing starts around $200/month but escalates quickly with geographic add-ons. Their primary customer base is building material manufacturers, lenders, and national data teams, not local renovation contractors. For a side-by-side breakdown against the $39/mo dashboard, see our Construction Monitor pricing comparison.
Best for: Building product manufacturers, suppliers, lenders, and analysts who need national construction activity data across all permit types.
Where Permit Ledger Fits
Permit Ledger is built for a different buyer than any of the above: local renovation contractors, investors, and home service businesses who want a simple, affordable way to get fresh renovation permit leads in their city.
The focus is deliberate. Rather than trying to cover all permit types nationally, Permit Ledger covers 338 major US cities with a renovation-only filter, meaning every insight reflects residential renovation, remodel, and addition activity. No commercial noise, no new construction to filter out, no raw portal exports to clean up.
Insights are free to browse, and the dashboard is $39/mo, low enough to test the channel before committing. No annual contract, no sales call required.
Best for: Renovation contractors, HVAC companies, roofers, electricians, and real estate investors who want a weekly feed of renovation permits for their city, without enterprise pricing or technical setup.
Which One Should You Choose?
The decision comes down to use case, not features:
- Building a product or internal tool on permit data with your engineering team? → Shovels
- Vetting subcontractors or accessing 25+ years of project history nationally? → BuildZoom
- Tracking national new construction activity for manufacturers, lenders, or investors? → ConstructionMonitor
- Getting free weekly renovation-permit insights for your city, with a $39/mo dashboard? → Permit Ledger
Most renovation contractors reading this comparison will find that Shovels, BuildZoom, and ConstructionMonitor are the wrong tools for the job, built for enterprise buyers at enterprise prices. Permit Ledger was designed specifically for the use case they need: local, residential, renovation-only, and accessible without a procurement process.
Frequently asked questions
How do Shovels and BuildZoom compare for building permit data?
Shovels is an API-first platform built for developer teams who want to build permit data into products or internal tools. BuildZoom is primarily a contractor marketplace with a data layer, best known for contractor history lookups. Both are national, enterprise-priced ($300–$2,000+/month), and not designed for local contractors looking for a simple weekly permit lead list.
What is the most affordable building permit database for contractors?
Permit Ledger is the most affordable option for renovation contractors, weekly insights are free, and the full dashboard is $39/mo with no annual contract. It covers 338 major US cities with a renovation-only filter, no commercial or new construction data mixed in.
Is there a free building permit database?
City and county open data portals are free, sites like data.cityofchicago.org, data.boston.gov, and data.sfgov.org publish permit records. The trade-off is that raw portal data requires significant filtering and cleaning. Permit Ledger offers free weekly renovation-only insights for all 338 cities at no cost.
Can I switch from Shovels or BuildZoom to Permit Ledger?
Yes, there is no contract or integration to unwind. Permit Ledger's insights are free to browse and the dashboard is month-to-month, so the migration is as simple as switching to it alongside your existing platform. Most renovation contractors who try Permit Ledger as a second source end up cutting the enterprise subscription within 60 days because the focused renovation, remodel, addition, repair, solar, and pool data is what they actually needed.
