Experience legalizing unpermitted remodel on Oakland,CA

[Brian K.]

Greetings BP community,

I am interesting in flipping a home in Oakland, CA.  There has been unpermitted work done in the past.  I would like to work with the building inspectors to legitimize the work, so that the city can reflect the additional bathroom and bedroom (converted attic) on their records.  Does anyone have any experience working with the city to legalize unpermitted work?  What has been your experience?  And how long it the process take?

Thanks in advance,

BK
