Detached Single-Family Residential properties (one individual, detached, single-family home on a parcel) are in one of four billing tiers based on the property’s total amount of impervious surface. Each property in the tier is billed the same amount.
Tier 1: <2,000 square feet of impervious surface
Tier 2: 2,000 to 2,999 square feet of impervious surface
Tier 3: 3,000 to 4,999 square feet of impervious surface
Tier 4: 5,000 or more square feet of impervious surface
All Other properties (commercial buildings; attached single-family homes such as duplexes, triplexes and apartments; multiple single-family structures on one parcel) are billed for the actual amount of impervious area on the property.
