Rule snapshot
These sections mirror the questions homeowners search for: size, setbacks, parking, permit workflow, and which ADU type is available. The rows stay source-backed and avoid turning a city rule into parcel approval.
Planning a garage conversion ADU?
Read the California garage conversion guide, then run the address check to match the city baseline to the actual lot.
Estimating ADU permit cost?
Permit cost depends on the fee stack, ADU type, size, waivers, and plan-check path for this city.
Oakland's official materials organize ADUs into category-style paths, which is helpful for homeowners comparing existing-envelope work against larger additions.
Oakland's practical answer often turns on mapped parking exemptions and fire or safety controls.
Oakland has separate official sources for ADU workflow, fee requirements, and impact fees.
Why this is a starting point
Competitor rule pages often stop at a city summary. The useful next step is matching those rules to an actual lot, because zoning, parcel geometry, overlays, and selected ADU type decide what a homeowner should do next.
Oakland's official materials split ADUs into category-style paths, including existing-envelope and larger expansion scenarios.
Parking can be waived in mapped no-parking areas or where another official exemption applies, so the practical answer depends on the parcel location.
The curated rows preserve fire and safety language for side and rear setbacks rather than simplifying it into a universal buildable-area promise.
Free ADU Check
The city page gets the search visitor in the door. The ADU Check turns the visit into a property-specific report path.
Start free address checkThe check matches the typed address to jurisdiction, zoning, parcel context, and the closest stored ADU rule path.
Detached, attached, conversion, garage conversion, and JADU paths are handled separately when the city source supports them.
The report keeps official rule text separate from parcel-specific caveats, so a homeowner can see the rule and the remaining risk.
