All of them: construction projects in Los Angeles by address. The data is the City of Los Angeles: the building permits the Department of Building and Safety (LADBS) issues. Santa Monica, Pasadena, Glendale, Burbank, Long Beach and the rest of Los Angeles County issue their own permits and are not in the feed today. The city's open dataset names no contractor, so Builtie reads each permit's LADBS record for the contractor and their CSLB license, the architect and the engineer. Many Los Angeles permits are owner-builder, and on those the architect is the first contact.
