Why this matters
For homeowners considering an ADU, requiring a separate sewer tap can be a significant cost barrier; allowing the ADU to share the primary dwelling’s sewer connection reduces installation costs and preempts local restrictions that might require otherwise. This continues a legislative pattern of state-level ADU enablement that constrains municipal zoning and utility rules to expand housing supply.
