I have a situation where an existing building has service outside with a bus and few spare enclosed breakers and future spare meter location for future use. They built this building with an expectation that at some point they will expand by adding additional small building (3000sqft building for office type space). The new building will be about 10 feet away from the existing building. The existing service has more than enough power to feed the new building. My question is, would i be able to feed this new building with the existing service provided and use the spare location for an enclosed breaker and meter (because they are going to rent it out to a different tenant), and provide a new panel inside this new building somewhere with a main circuit breaker? Or does this new building require its own separate service from the utility since technically the new building and old building are not connected.

If you want to meter the new building separately then I would just run from the spare meter location and set this up as a new service. If you go with the feeder from the existing building then you need to figure out how you're going to meter it.
Thanks! Can i put the new meter on the existing building and run feeder to the new building panel? Does the new meter need to be on the new building?

NEC doesn't care where the meter is or if there even is one. That can be something POCO's have their own rules about or possibly local jurisdictional regulations on such things.
Code wise if you do it this way it is not service conductors supplying your additional building, the service disconnect is at the meter center, it becomes an art 225 outside feeder instead of an art 230 service, and in more recent editions of NEC would require separate grounded and equipment grounding conductors in the feeder as well.
