DADU - How does that work?

[Brian Sweeney]

My rental property has a garage with upstairs apartment that was once used. It has since fallen into disrepair and now that I'm the owner I'm considering rehabbing the garage and apartment for additional income.
Anyone done this before?

What issues did you run into?

How do addresses work with a DADU? It doesn't appear to be a separate mailing address.

Any zoning issues? Would you suggest contacting the city to remain compliant or does zoning apply to DADU's?
