Construction Burbank, CA
Hi all! I have a detached garage in my backyard that I barely use for storage, and I'm wondering if I can build an ADU on top of it. The garage seems pretty solid and I think it would be a great way to add living space without taking up more of my yard. Is this something that's allowed in Burbank? Are there height restrictions I need to worry about? Also, would I need to add stairs from the outside, or could I connect it internally? Thanks for any advice - this seems like it could be a really efficient use of space!

Argi from the GatherADU team here! Yes, you can build an ADU on top of a detached garage, with a max height of 20 feet to the top of plate and 23 feet to the roof, per BMC 10-1-620.3(G)(2). The ADU's floor must be above the garage's top plate, and ground-floor access (e.g., stairs) is limited to 150 sq ft.
