What are some challenges with being a landlord in California?

[Raj A.]

I've seen some comments on recent posts along the lines of "...but I won't be investing in California because the laws and regulations are very unfriendly to owners/landlords." On paper I recognize California is a high tax/high regulation state (lived here for over a decade and wouldn't refute that) but I'm curious if anyone has specific regulations or laws in mind that they can share that make ownership/landlording more difficult than other areas of the country. Even better if you know of local Bay Area laws to point to or in consideration under legislature in the area. For example, I know Palm Springs has a limit on how many STR licenses a business entity can have and Napa/Sonoma are either in the process of limiting or have already limited the number of STR licenses in the county Links, resources etc. would be great.
