Burbank FAQ
If I convert my Burbank garage to an ADU, do I need a replacement parking space?

Can I build a new ADU on top of my Burbank garage?
Yes. Under BMC §10-1-620.3, a detached ADU built on top of a garage or other accessory structure may be up to 20 feet to top of plate and 23 feet to top of roof or architectural feature.
