There might not be any difference between the three terms. But, it would depend on who you ask.
I am going to paraphrase the late Charles Akerson, who was the authority on income valuation.
There is net (everything passed-through to tenant) and there is gross (nothing passed through). Everything else is something in between. The arrangement that you discussed was something in between. It is not a gross lease because the tenant would pay for utilities and janitorial expenses. The best way to identify a lease is to get very specific because one person's net lease may or may not be the same as another person's triple-net lease. Then throw in modified gross, industrial gross, modified net, full-service, etc. and there is bound to be confusion.
