- Owner-occupied multi-gen use is the dominant intent here.
№ 02 — Questions
South Pasadena ADU questions, answered.
Can I add a detached ADU in a designated historic district?
Yes — South Pasadena requires Cultural Heritage Commission review on contributing structures; rear-yard ADUs typically clear with material specs and roof-pitch sympathy.
Rent vs family use?
70% of South Pasadena clients build for family; rent comps still strong at $3,000 1-BR / $3,600 2-BR.
Local plan-check turnaround?
6–8 months end-to-end; the City contracts to outside reviewers during permit peaks.
