1. What Is SB 1211?
Core Provisions:
Ministerial Approval: Permits must be approved non-discretionarily within ~60 days.
Up to Eight Detached ADUs: Allowed, so long as count doesn’t exceed existing multifamily units on site.
Audit of Conversions: Up to 25% of units within an existing structure can be converted to ADUs.
Parking Flexibility: No off-street parking replacement required when converting carports, garages, or driveways; near transit, parking may be waived entirely.
Objective Standards Only: Local rules limited to clear criteria—height ≤18 ft, setbacks ≤4 ft, max 1,200 sq ft per detached ADU.
Fee & Utility Relief: No impact fees for ADUs under 750 sq ft; utility fees must be proportionate.
2. Why SB 1211 Matters
Amplifying Housing Supply
California faces a dire shortage—millions of homes needed by 2030. SB 1211 empowers owners of duplexes, triplexes, or larger properties to create significant infill capacity without new land.
Streamlined & Predictable Process
Ministerial approval eliminates discretionary reviews—meaning faster permits in roughly 60 days.
Reduced Cost Barriers
No redundant parking replacements and scaled-down fees make additional units more financially viable.
Transit-Oriented Opportunity
Near transit, parking mandates disappear—ideal for urban infill and sustainability goals.
