Why are they called “tier” fees?
Linden Labs actually calls them “Land Use Fees”; the TQB Group uses the term “Monthly Maintenance Fee”. Both LL & the TQB Group use a tiered fee schedule; the amount of land you own determines what tier level you are at and the amount of your monthly fee. The phrase “tier fee” is commonly used instead of “land use fee at the tier level for (land size)”.
