Differential Rating System - Billing Categories

Print Page

Rates are calculated using a differential rating system that is based on land use.

The system first classifies a property as either a base differential (includes residential properties) or commercial, industrial and business differential. The property is further classified by a billing category to indicate the targeted rates it receives, and whether it is fully or partially non-rateable.

The billing categories are as follows:
