№ 02 — Questions
Noe Valley ADU questions, answered.
How long does an SF ADU permit take?
9–14 months end-to-end — Planning Department's HSP review adds 4–6 months beyond standard DBI plan-check.
Can I add a rear-yard detached ADU in Noe Valley?
Rarely — most lots are too narrow for a detached form to clear setbacks. Horizontal in-law conversions dominate.
What's the rent comp?
Ground-floor 1-BR in-law units rent at $3,500–$4,100; SF tenant protections apply (ADUs ARE rent-controlled here).
