City and State comparison
The data includes multiple City and State paths, which supports a comparison-style report when both standards are available for the same ADU type.
Placement details
Local side, rear, and separation requirements can vary by placement, so the page uses official rows and leaves lot-specific interpretation to the report flow.

California ADU law creates statewide minimum paths, while cities keep local standards for many project types. Showing both paths keeps the homeowner from treating a single city rule as the whole answer.
Run an address-specific feasibility check. The report combines official city rules with deterministic GIS and parcel data so the next question becomes what fits on your actual lot.
