Can you build more than one home on a Los Angeles property?
Sometimes. SB 9 lets an owner split a single-family property into two with up to two homes on each, outside very high fire hazard zones and historic districts, with an affidavit to live in one home for three years. SB 684 allows up to 10 homes on a multifamily-zoned property of 5 acres or less, and SB 1211 allows up to 8 detached ADUs on an existing multifamily property. A property may qualify; a review decides.

The report shows "Room for more than one home: may qualify" and a "Talk to Vivienda" button. It never says a property qualifies; that takes a review.
