I have seen this repeatedly in telco documents.
Problem:
The noun “premise” does not refer to location.
Explanation:
Dictionary.com has the best explanation about why we call a single building the premises and NOT the premise.
Here is a simple way to remember which noun to use when: premise is a logic term, whereas premises is usually a location term (unless you’re talking about a multiple of premise).
I also believe that use of “premise” instead of “premises” helps to prove my “Devolution toward Simpler” linguistic hypothesis. It is simpler to say “premise” (two syllables) than to say “premises” (three syllables).
Solution:
“Premises Installer”
