Building permit data, answered

Building permits are the public records a city or county issues whenever a property is built, altered, or repaired: roofs, additions, electrical and plumbing work, solar, pools, and more. Each one is a dated, government-issued record of a physical change. Aggregated nationally, permits are the most complete public record of what has actually been built across the U.S. property stock.

Builty collects raw municipal building-permit records from thousands of U.S. jurisdictions and structures them into clean, analysis-ready property intelligence: an insurance-native schema plus property risk scores. Instead of unreadable text like "REROOF W/ TEAR OFF 18 SQ," you get structured fields: project type, material, scope, status, and derived risk.

Directly from the source: public building-permit records collected from thousands of individual U.S. municipal jurisdictions. Builty is the source of record, not a reseller of another vendor's feed, which is what lets carriers rely on it inside their own systems.

It gives adjusters a pre-loss condition baseline: the permitted history of a property before the loss. That establishes roof age and prior repairs, supports scope and pre-existing-damage discussions, and helps resolve claims faster and more consistently.

At quote, bind, and renewal, permit history supplies verified property variables (roof age, fire protection, electrical and plumbing condition, occupancy change, and structural modification), so pricing reflects what has actually been built rather than what an applicant disclosed.

A library of 10+ proprietary risk scores, derived entirely from permit history and delivered at the property, neighborhood, and portfolio level. Rather than a single roof-age number, they span a property's condition and change, catastrophe resilience across perils, and reconstruction value: the dimensions that move property risk. Exact score definitions are shared under NDA.

Builty's records span thousands of U.S. jurisdictions, covering roughly 80% of the U.S. population, with 300M+ permit records structured to date and 25+ years of history.
