CA SB1211

Prohibits local agencies from requiring replacement of off-street parking spaces (including uncovered spaces) when a garage, carport, covered parking structure, or uncovered parking space is demolished or converted to create an ADU.

Defines "livable space" as space in a dwelling intended for human habitation, including living, sleeping, eating, cooking, or sanitation, for purposes of ADU regulations.

Increases the number of detached ADUs allowed on multifamily dwelling lots from a maximum of 2 to up to 8 units on existing multifamily lots (not exceeding the number of existing units) and up to 2 units on proposed multifamily lots.

Prohibits local agencies from imposing any objective development or design standards on ADUs that are not specifically authorized by state law for units meeting statutory requirements.

Clarifies that no state reimbursement is required because local agencies have authority to levy fees or assessments sufficient to pay for the mandated program.
