Commerical Condo Unit......Back to Residental

[Matt K.]

Forgive me if this is an obvious answer but I've come into some trouble finding that answer. I'd assume more info is needed but for the most part this really just theoretical. Please see the scenario below:

Condo Unit being used as a cafe (ground floor unit). 6 year Lease @ X amount per month. 2% Annual Increase. Currently on 3rd year. 3 year option to extend at end of the lease. Tenant pays all utilities, landlord pays HOA.

Location: Bay Area, CA

Now... this unit rents for above what one would get with your typical tenant. However, if say business no longer wanted to lease unit or landlord decided to convert it back to residential would that be possible? Would this require change in zoning/permits/ restriction from HOA?

I don't really have more specific info and again I'm just looking at this from a theoretical view to see if it's even worth further investigating. I do however know that there are few units that would fall in line with the scenario posted.

This is my first post and I've tried hard to find the answers on my own... but I am obviously not searching correctly.
