Is there usually an on-campus interview when hiring a lecturer with a one year contract?
It might depend on circumstances. If the contract is non-renewable then perhaps not provided that the CV and letters of recommendation are strong enough for the hiring department to "take a chance". For a renewable contract, the likelihood of requiring an interview probably increase. Also the kind of institution is a factor. 

The institution bears responsibility for the people it puts in front of students so there is pretty strong incentive for interviews. Financial imperatives push the other way. 

So, common, yes, but not universal.
