Residential Rates

Residential properties are assigned an Equivalent Dwelling Unit (EDU) based upon the actual dwelling units (living units) permitted on the property, regardless of occupancy, as determined by the Marin County Assessor Office records. The 5-year rate plan adopted in May 2014 recognizes the difference in average water usage between single-family and multi-family residences and applies a different per EDU rate for each. Condominiums are included in the multi-family classification.
