Going from unpermitted to permitted addition in Oakland?

[Anthony Barbato]

Hello,

I have a couple off market properties in Oakland that I see that look like potential deals, however the finished square footage on the tax roll does not equal the current state of the property. The owners have made additions to the property and didn't get the additional work permitted when they did it. Now that they're ready to sell, what is the process for the next buyer to correct it so that the additional square footage is legal?

Thank you
