Sacramento's ADU Resource Center presents City and state standards as separate paths that cannot be mixed. Its state path can pair a converted ADU with a junior ADU and a new detached ADU. The City path caps the lot at two ADUs or junior ADUs.

No. Sacramento City Code 17.608.020, cited on the City's Parking Revisions page, says parking removed for an ADU or junior ADU need not be replaced. Gov. Code 66314(d)(11) also covers a garage converted to an ADU.
The City ADU Resource Center's Step 1 describes a state-standards path with a converted ADU, a junior ADU and a new detached ADU. Sacramento City Code 17.228.105(A) says the City and state paths cannot be mixed.
Gov. Code 66314(d)(7) says no new setback is required for an existing accessory structure converted to an ADU, or one rebuilt in the same place and dimensions. A particular garage still needs permit review by the City.
Neither. It is a screening from public records, not professional advice, and not a survey, soils report, appraisal, loan offer or permit; every number is an estimate. A licensed designer confirms the final plan, and your city or county gives final approval.
