Choose the right Fiber Cable for building

Can I use single Mode cable 9/125 OS2 for the building with 100 meters or I have to use multi mode fiber cable (OM2, OM3,...)?

Thanks for your help.

You can use single mode for any distance, however the transceiver/receivers power might need to be adjusted (attenuator). Actually, since the cost of single mode vs multi mode have become more comparable, most people are going single mode throughout, for future proofing their cable runs.

You wouldn't put in OM2,OM3 nowadays, OM4 typically if you go that route. Most people just use it in their data center (rack to rack).
