RSA Development offers (Alternative, Fundamental, Geospatial) — 306,058 parsed LADBS permit records (2020-01-02 to 2026-09-19, no repeated permit numbers), of which 65,252 submissions and 55,483 issuances fall in the tracked monthly window with 12,401 recording an ADU increase; plus Beverly Hills monthly permit reports, Census county/place series, a 1,267-page 88-city planning library, and an internal 2018-2025 California residential project cost set.
ADU and small-lot feasibility modelling (whether a given LA parcel can be entitled and at what cost); training cost-estimation and take-off models on realised build outcomes rather than contractor bids; jurisdiction ranking by approval friction across 88 LA County cities; measuring true ADU production net of the multifamily-dominated headline counts; LLM ground-truth corpora for California planning-code Q&A with hash-verifiable provenance; validation layer for proptech tools that scrape LADBS but cannot classify ADU intent.
