Overview
This bill changes regulations around accessory dwelling units (ADUs) in California, particularly concerning private sewage disposal systems. It prohibits local agencies from denying ADU approval solely because a property uses a private sewage system, as long as the system meets state standards. The bill also prevents health officers from requiring minimum lot size requirements based on sewage systems and prohibits installing new systems unless absolutely necessary. It clarifies parking requirements and streamlines the approval process for existing systems.
Key provisions
- Local agencies cannot prohibit ADUs due to private sewage systems meeting state standards.
- Health officers cannot withhold approval based on minimum lot size requirements for private sewage systems.
- Local agencies cannot require new or alternative sewage systems unless there's a risk to public health or water quality.
- Parking requirements for ADUs are limited to one space per unit or bedroom.
- Existing off-street parking spaces don't need to be replaced when a garage is demolished for an ADU.
- Fire sprinkler requirements for ADUs are not triggered by the demolition of a garage.
- The bill clarifies that ADUs do not increase density beyond existing allowances.
- Local agencies cannot require notice or placards for garage demolitions related to ADU construction (except in historic districts).
