1. To buy a Flat in the floor which is in a deviated part of the building even after the building gets OC is not legal.

2. This extra one floor be always illegal even after the building gets OC, if the builder does not obtain revised sanctioned plan for the 8th floor.

3. Akrama-Sakrama scheme which is in the offing may regularise the deviation which you are quoting.

4. If there is more deviation than it is permitted, the BBMP may deny OC.

5. The above answers are given based on your narration of the question. However it is better to get the documents scrutinized by a Lawyer and obtain his opinion and then decide taking further steps.

If OC is obtained no harm in purchase of flat as deviation has been regularised

2) if OC given for entire building then 8 th floor would not be illegal

3) don't purchase flat until issue of OC

You intend to buy the flat in the 8th floor which floor has not been duly sanctioned by BBMP. In this scenario after inspection of the building if the BBMP does provide the OC with a penalty, and if the same is paid by the builder at that time, then it is very safe to move ahead and purchase the flat. Otherwise, no nationalized bank will come forward to finance the purchase (that is if you intend to avail a home loan).

In the scenario where the modified plan submitted by the builder get approved or sanctioned by BBMP, then there is no difficulty to purchase the flat and after submitting the modified plan to the bank you can get loan to make the purchase.

In any event if the modified plan gets approved or the builder pays the penalty and obtains the OC for the project, your building will get A Katha. Otherwise if both fail, the BBMP will only issue a B Katha.

1.Is this a problem to have a flat (2 BHK in 8th floor) in the deviated part of the building even after the building obtains OC?

The approval now being procured would not be in a legal manner. If a honest officer comes to this post at a later date, then this will be reopened and the illegal approval may come to light and may be brought under demolition.

If you are ready to undertake risk and would stake your investment then you may proceed.

2. Will this extra one floor be always illegal even after the building obtains OC?

Yes, it would remain illegally constructed structure and the sword will remain hung on the head always.

3. Do you foresee any issue in the future which I might have overlooked around the same?

You may seek a lawyer's opinion by producing the property document s before him and then decide, nothing can be conted without seeing the relevant papers.

4. Can the BBMP deny the OC even after the final verification?

It depends. the authorities may turn a blind eye but it is not necessary that can overlook the irregularity.
