How to find comps for properties w/ADU

[Nicholas Williams]

Hello!

I'm looking to house hack by converting a detached garage to an ADU. My town may be opening up permits for this soon, so I'm trying to prepare for the best case scenario where ordinances change to allow ADUs in the near future. My strategy is to short term rent the ADU.

I'm trying to understand the value of the property after adding the ADU so I can start shopping around for financing. What sites or approaches can I use, given my town has not permitted construction of ADUs historically, but there may be some non-permitted ones out there?
