Parking & Access Santa Monica, CA
I'm working with contractors on my Santa Monica ADU and a question came up about converting garages to JADUs. The architect mentioned this might be an issue with Santa Monica's rules. I'd rather get clarity from the community before we proceed. Anyone have experience with this?

Argi from the GatherADU team here! Ordinance 9.31.025(I)(1)(c) requires JADUs to be within the single-unit dwelling’s footprint, excluding attached garages, but HCD findings (2/26/2024) note this violates Government Code 65852.2(a)(4), which includes attached garages as part of the dwelling. The city must amend to allow JADU garage conversions.
