Garage conversions go through the same general permitting process as other ADU projects, including design review, plan submission to the City of Pasadena, and inspections during construction, though the specific plans and details submitted reflect the scope of converting an existing structure rather than building a new one. Permitting for a conversion needs to address how the existing structure will be brought up to current requirements for a residential unit, which can sometimes involve more detailed documentation of the existing structure’s condition than new construction does, since the city needs to understand what is being modified rather than just what is being built new. ADU Builders Pasadena manages this permitting process for garage conversion projects, preparing the documentation needed to address both new work and how it relates to the existing structure.
