Daily-refreshed, cleaned building-permit data for major US cities — one normalized schema, business entities only, no personal data. Query by ZIP, permit type, segment, and date.
The GET List Building Permits endpoint returns detailed building permit records, including address, contractor information, permit type, and issue date. The GET Permit Statistics endpoint provides aggregate statistics, such as total record counts and counts by permit type and segment. The GET API Health Check endpoint returns the API's health status, dataset name, total record count, and retrieval date.
Key fields in the building permits response include address, city, contractor company, permit number, permit type, issue date, and square footage for new or remodeled spaces. In the statistics response, key fields include total counts, counts by permit type, segment, and issue date.
The response data is structured in JSON format. For building permits, it includes a "count" of records and a "results" array containing individual permit details. The statistics response includes total counts and categorized counts organized by type, segment, and issue date.
The GET List Building Permits endpoint accepts parameters such as ZIP code, permit type, segment, issue date, and a limit for the number of results. The GET Permit Statistics endpoint does not require additional parameters, as it provides aggregate data for the entire dataset.
The GET List Building Permits endpoint provides detailed permit records for specific queries, while the GET Permit Statistics endpoint offers aggregate data on permit counts by type, segment, and issue date. The GET API Health Check endpoint provides the API's operational status and dataset information.
Data accuracy is maintained through daily refreshes and cleaning processes that ensure the building permit records are up-to-date and normalized. The API focuses on business entities only, excluding personal data, which enhances data quality and relevance.
Typical use cases include urban planning, market analysis for construction trends, and compliance monitoring for contractors. Researchers and developers can use the data to analyze building activity patterns and assess the impact of regulations on construction.
Users can analyze the returned data to identify trends in building permits, compare activity across different regions or permit types, and generate reports. The structured JSON format allows for easy integration into applications or data analysis tools for further insights.
