Our City has no Ordnance for Multifamily ADUs, We are using state law SB 13, it says we must approve not more than 2 detached ADU's with a 16-foot height limit. A potential applicant is sneaking to build a 16' tall ADU on top of an 10' detached garage on an existing multifamily development. This dose meet our height development standards for the underlying code, But is this the correct interpretation of the new 2020 ADU laws or should we be considering total developed height?

Welcome to Cyburbia! Things are kind of slow on weekends, so you might not get an answer until Monday. Just wanted to say we’re not ignoring you!

Sorry, hopefully one of our west coast planners will show up. We don't do that kind of crazy in Arizona. We have our own kind.

The state law is just specifying that, regardless of other site development requirements, you must permit an 800 square foot ADU, 4 feet from side and rear property lines, and up to 16 feet tall. IIRC, some cities had established a smaller height requirement, hence the new change. I would not interpret it to mean 16 feet of structure in addition to the height of an existing structure, as no other height limit is defined in that way. Our city does establish a discretionary review process for larger detached structures, so the example you provided would be subject to that review and not be exempted by SB 13 et. al..
