I’m having a house renovated and I always plan for the future. While the walls are open, I asked the electrician to install a 1.5 inch PVC conduit in the wall from the basement to the attic in a two story house for any future wire runs. The electrican said there may be a fire code issue. Does anyone know the answer? I placed a call into the town. I cannot find anything in NEC, etc.

That becomes a chimney in a fire. Put a box with a cover on each end and you are OK.
would it suffice to put a Conduit body on the end line?

If you plugged the unused hole the conduit body should make them happy.
Another thought is to put a male adapter on the end with a pipe cap on it until you need it. Then you can take off the cap and set the box or whatever else you want. They probably want that pipe foamed in (draft stopping, not fire stopping).
And don't just install one.
What gfretwell said works around here.
Some inspectors want metal pipe rather than PVC, rigid or EMT.

Put tees and pull boxes at each floor too. Easier now than later.

In addition to blocking the pipe itself, the clearance around it needs to be filled. At the basement, first to second floor penetration and at the attic level.
The inspectors in our town are very critical on draft blocking as it's a fire issue.
