Had any horror stories renting in Law Suites or ADUs?

[Jon S.]

Have there been any horror stories about renting out in-law-suites that don't have a separate address? I'm contemplating renting an in-law-suite that doesn't have a separate address. While I know many people do this with their rental properties, I am wondering if anyone has had any horror stories as a result of doing so?

@Jon S, most of the issues I've seen boils down to HOA / code enforcement / underestimation of utility usage. Most properties covered by HOAs with in law suites can't be rented out without running afoul HOA regulations. Those can be really, really terrible if you violate them.
