Pasadena / ADU construction

ADU construction in Pasadena

Pasadena's Planning Division publishes ADU guidance and information on its standard-plan program. A standard plan can simplify design, but the unit still has to fit your lot's access, utilities and any designation that applies.

01

What shapes this work here

Standard plans, site still reviewed

A standard plan addresses the building; setbacks, utility routes and site conditions are still checked for your parcel.

Detached vs conversion

Older detached garages may be close to property lines and in varied condition; evaluation decides whether conversion is sensible.

Designations still matter

If a historic designation applies, exterior design may receive additional review. Ask Planning.
