ADU Regulations in Pacifica, California (2026)

Regulations at a glance

Local rules & notes

Coastal Access Parking Area Conflict: The Coastal Commission proposed modifications to mandate off-street parking for ADUs in 'coastal access parking areas' even if they are within 1/2 mile of transit, which conflicts with state ADU law. Transit as Parking Substitute: Pacifica LUP Policy 25 and the Coastal Act specify that providing public transit service is a valid substitute for parking requirements. Coastal Act Housing Mandate: The Coastal Act requires the Commission to encourage housing opportunities for low- and moderate-income households, supporting the creation of ADUs.
