Hi there, 

it can be caused by many things. If you rent mainland, or have rented a small place at like a shop or small home instead of a whole parcel you will need to wear the group tag the land is under to rez.
When you go to a sandbox, make sure that rezzing is allowed in the area you stand in, most sandboxes (except for premium ones and a small handful of others) do not allow rezzing right at the landing point but you need to walk to the designated area(s).
Other causes can be, that you're trying to rez something on a mesh surface, which most of the time unfortunately doesn't work until you put a solid prim on the floor (and make it invisible) to act as a second ground.
Or that you have a connection issue.

If you'd like you can edit your post and add more details, so we can narrow down the problem.
