If you're in the U.S., yes.

No. Without a license your limitations are plainly set out in the R&R's
of the FCC and they have nothing to do with the size of your property.

They can go where they need to take field readings subject, of course,
to the laws regarding trespassing. But I guarantee if they get an
abnormally high reading from an unlicensed site they will be knocking on
your door. First, though, they have to be there. Unless there is a
complaint or they just happen to be in the area the chances are slim
they will be. They don't have that much enforcement muscle and generally
go for the big-time violators (can you say running an RCA BTA-250L on
your back porch in illegal? I knew you could :) ). People interfering
with licensed broadcast facilities are asking for a visit. 

Speaking as a former commercial broadcast engineer BTW. The rules have
changed a bit since I was last active in the business but they haven't
changed THAT much....
