Parking exemptions
Parking can be waived in mapped no-parking areas or where another official exemption applies, so the practical answer depends on the parcel location.
Fire and safety controls
The curated rows preserve fire and safety language for side and rear setbacks rather than simplifying it into a universal buildable-area promise.
Check these rules against your lot
City rules explain the ceiling. Your parcel determines the practical answer: zoning, lot size, APN, setbacks, overlays, and buildable area.

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.
