Permits / Authority
Pasadena permits
Pasadena has its own Planning department and a large stock of older and historic houses. Ask Planning first whether a designation or design review applies to your property; the City's ADU page includes its standard-plan program.
Official starting points
Designation check
Landmark or historic district status changes how exterior work is reviewed; confirm it for your address.
Standard-plan ADUs
A standard plan simplifies the building design; site and designation still matter.
Who reviews what, and where to start
Planning review (land use, overlays, design) and building review (drawings, permits, inspections) can be separate offices. The current checklist lives on each office's official page; the links below are the starting point, not the checklist itself.
