Rent control and eviction rules
Los Angeles' Rent Stabilization Ordinance generally covers rentals first built on or before October 1, 1978, and caps yearly increases on those units at 3% from July 1, 2026 through June 30, 2027.
For investors: The 3% applies once per 12 months, and since February 2, 2026 no utility add-on is allowed, so a pre-1979 Los Angeles fourplex grows slowly with sitting tenants. Price the deal on in-place rents and treat vacancy resets to market as the upside.

On a Los Angeles property first built by October 1, 1978, rent stabilization covers duplexes, ADUs, junior ADUs and multiple houses on one parcel; condo and townhome rents for post-1995 tenancies are unregulated.
For investors: A buyer adding an ADU behind an older Los Angeles duplex should expect it may join the same RSO registration and fee bills. Look the address up in the city ZIMAS system under the Housing tab before assuming a small property is exempt.
