Twnship Housing code violation-Elect Pnl- not disclosed @ Sale

[Sastry Srini]

Hello BPers

Seeking some help on this situation.. 

Last year October, I bought a SFR in Ann Arbor and is currently tenanted. During township inspection July of this year, township inspector found a violation of electric panel. The exact wording of the violation is as follows..

"Permit and inspection required for new electrical panel"

Inquiring with seller, it appears no permit was drawn. Got one quote for electric panel upgrade ( demoing existing panel and moving it to meet housing codes) approx $3600.. waiting for other quotes.

What are my options here?

A) can I go after Seller for this was revealed during the sale? I had the inspection done, nothing was stated in the inspection report

B) absorb the cost and upgrade?

C) can I appeal the violation to township?

Any pointers on this would greatly help..
