Technically, with the R1 zoning you can have 1 ADU and 1 JADU (if the property is owner occupied), but you may be able to use SB9 (Senate Bill 9) to have 2 units on an SFR zoned lot and, depending on if LA allows it, an ADU for 1 or both dwellings.

When you say "DADU", we're talking about a dethatched accessory dwelling on the same lot as an existing single family home.

FWIW if I was to dwell on the past I'd probably never get out of bed lol.

One of the good things about Tacoma is that it allows non-owner occupied Accessory Dwell Unit (ADU).
