RD3 Zoning
Los Angeles
RD3 — Restricted Density Multiple Dwelling. 1 unit per 1,200 sq ft of lot area under LAMC Title 12. On a 7,500 sq ft lot this allows approximately 6 units by-right, rising to roughly 10 units with a TOC Tier 4 bonus. Typical use: Low-rise multifamily, courtyard apartments.

RD3 reads like RD1.5/RD2 on density but typically carries larger minimum lot sizes — check the specific tract before underwriting unit count.
