Validation Thesis

This concept is only built further if tracked requests, demo clicks, or marketplace intent justify the build.

Permit-driven project lead discovery for contractors and suppliers.
Property work-history monitoring for real estate, insurance, and inspection workflows.
CSV/report subscription path for non-developer sales and operations teams.

Public Data Sources

The initial product would normalize public records into stable polling endpoints and exports.

Buyer Workflows

These are the specific self-serve workflows this page is testing before any backend is built.

Building permit alert feed

Normalize permit records by region, job type, permit type, status, filing date, address, and source for lead and watchlist workflows.

Property work-history enrichment

Attach source-linked permit activity to property profiles, inspection queues, underwriting checks, or due-diligence spreadsheets.

Construction sales report export

Refresh CSV snapshots for contractors, suppliers, and sales teams watching new project activity in selected jurisdictions.

Specific Workflow Tests

These pages test sharper buyer searches before implementation.

Monetization Hypothesis

Pricing only becomes meaningful after tracked demand appears. The first offer should stay narrow and low-touch.

CSV/report subscription for contractors, suppliers, real estate, and insurance teams
API subscription for proptech, CRM enrichment, and property watchlist products
No zoning advice, contractor recommendation, compliance certification, or lead qualification claims

Validation FAQ

Is this building permit API live?

No. This is a validation page. Build priority depends on tracked request, sample-download, demo, and paid-API intent.

Would it verify construction compliance or contractor quality?

No. The proposed product would provide source-linked public and licensed permit records only. Buyers remain responsible for compliance, diligence, contractor selection, and permitting decisions.
