Garage insulation requirement

[Remington]

Do the codes in Los Angeles require residential garages to have wall insulation ?

 

[JBI]

Generally the wall that adjoins the dwelling would be part of the 'thermal envelope' and requires insulation.
California and/or Los Angeles may have amendments that would require it, but I don't know left coast codes that well.

In California, LA included, code requires insulation in the wall between the Garage and the dwelling.
Not in the exterior wall of a garage.

It’s not a bad idea. Especially if the garage will become an ADU.

…. garage will become an ADU.

I'm guessing that if heat is supplied to the garage for whatever reason (radiant floor?) the energy code will require insulated walls and roof and slab.

Yes, it becomes "conditioned Space".
