CA AB682

Expands California's Density Bonus Law to include shared housing buildings as eligible developments for density bonuses if they contain 10% lower-income units, 5% very low-income units, are senior housing developments, or are 100% lower-income housing.

Prohibits cities, counties, or city and counties from requiring minimum unit size or minimum bedroom requirements for shared housing buildings that conflict with the bill's definition of shared housing units.

Defines a "shared housing building" as a residential or mixed-use structure with 5+ shared housing units and common kitchens and dining areas for permanent residents, allowing up to 25% non-shared units and incidental ground-floor commercial uses.

Defines a "shared housing unit" as habitable rooms with a bathroom, sink, refrigerator, and microwave meeting California Residential Code minimum room area standards and guestroom definitions.

Clarifies that local governments cannot require additional reports or studies beyond those mandated by state law when processing density bonus applications.
