ADU Construction in South Pasadena
South Pasadena ADUs with the parking question answered first: what state law waives, garage conversions, the driveway, then city plans, permit and build.
Will we have to add parking for the small house? That may be one of the first questions on a South Pasadena lot, and state law answers much of it. A new ADU needs no parking space of its own in several cases, such as a lot close to public transit, and converting a garage does not require the lost spaces to be replaced. We confirm which case applies before the unit is drawn.
How the driveway shapes the plan
Even when no space is required, the driveway still matters. It is the delivery route during construction and the way the family reaches the door afterward. We keep it clear of the unit's footprint and decide early whether a car will park on it, since that sets where the walkway to the unit can run. When the ADU application goes in together with the plans for a replacement house, state law also removes the parking requirement for the unit, which can simplify a rebuild.
South Pasadena review
The city's building department reviews the site plan, where the driveway, any parking and the walkway to the unit are drawn, along with setbacks and the separation between buildings. Planning staff may check the unit against the city's own ADU rules on size and placement, within the limits state law sets. We note on the plans which parking exemption applies, and why, so the reviewer does not have to ask. Utility routes to the unit are shown on the same sheet.

ADU Construction in South Pasadena: questions
In that order, the driveway does double duty. If South Pasadena accepts the sequence for your lot, the family lives in the small house and parks on the drive or the street while the main house goes up. Later, the unit can stay with family or be rented within the city's rules. Its final inspection comes before move-in.
The package is open to it once the design is fixed at a single story and 500 square feet or under. On a South Pasadena lot we confirm room inside the setbacks and a route for utilities, and mark the driveway and any parking on the site plan during that visit. A larger or taller design is drawn under its own scope.
It can, and state law does not ask for the garage spaces to be replaced. The open questions are physical: whether the slab has a vapor barrier, whether the framing can take insulation and a ceiling, and how the car opening becomes a wall with a door or window. Those answers set the scope.
