Abandoned 4 plex renovation - Bring it up to code?

[Thripura Vemireddy]

Hi

I bought an abandoned quad, when I went to city for applying for renovation permit, they told me to bring it upto code like ( fire wall, fire sprinkler, replace wall panels with drywall...etc).

Based on the location and size of the building the renovation is going to cost a way more than what it can sell for or the rents it gets.

Is there any exemption i can request the city, to grandfather the building with minimal code.

I appreciate any valuable suggestion.

Thanks
