State-law administration
The curated paths distinguish state-law administration from local requirements, which keeps the rule-card comparison honest for homeowners.
Parking and occupancy rows
Parking and owner-occupancy rules are kept as explicit fields because these are common homeowner decision points and can change by project type.
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.

Long Beach ADU FAQ
No. These pages summarize official city and state rule sources for planning research. Permit approval still depends on parcel geometry, zoning details, overlays, easements, fire access, utilities, and plan-check review.
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.
