If you manage commercial properties -- or invest in them -- you already know the pain of tracking what's happening across a portfolio. Tenants pull permits without telling you. Tax assessments change. Neighboring parcels get rezoned.
Most property managers check this stuff manually, one county website at a time. Here's how to automate it.
What Public Data Actually Tells You
Building permits reveal construction activity. If your tenant is doing unpermitted work, or if the building next door is getting a major renovation, you want to know before it becomes your problem.
- Building Permits & Construction Leads -- $3.50/1K results (covers Socrata-connected municipalities)
Property tax records show assessed values, ownership changes, and tax delinquency. If you're evaluating an acquisition, this is due diligence 101.
- Dallas County Property Tax Search -- $3.50/1K results
Entity verification confirms who actually owns the LLC behind a property. Most commercial real estate is held through entities, and verifying the entity status across states catches problems early.
- US Business Entity Search -- $3.50/1K results (multi-state)
- California Business Leads -- $3.50/1K results
- Florida Business Leads -- $3.50/1K results
A Practical Monitoring Setup
- Weekly permit scan for your portfolio zip codes -- flag any permits tied to your addresses or adjacent parcels
- Monthly entity check on all LLCs in your ownership chain -- catch dissolved or suspended entities before they become liability issues
- Quarterly tax assessment review to spot valuation changes that affect cap rates
You can wire all of these into n8n or Make.com for scheduled runs, or just hit the APIs directly from a script.
Why Bother Automating This
Because the alternative is paying someone to check 15 county websites every week, or not checking at all and getting surprised. Neither is good property management.
The data is all public. The portals are just painful to use manually at scale.
