Can I build an ADU in a Pasadena Landmark District?

Yes — Landmark District ADUs are permitted but require additional design review focused on compatibility with the historic character. We have a documented track record with the process.

How does Pasadena differ from LA City for ADUs?

Pasadena runs its own building department, has its own historic review, protects mature trees aggressively, and tends to be more deliberate on design — but ministerial approval still applies under state law for compliant projects.

Pasadena permit notes · City of Pasadena Planning & Building

What we resolve before drawings begin.

01
Historic district review
Landmark District parcels and historic-designated properties go through additional review. We engage at concept, not at permit.
02
Craftsman compatibility
ADUs visible from the street need to read as compatible with the primary structure — materials, massing, fenestration. We design for this from sketch one.
03
Mature trees and root protection
Pasadena protects mature trees aggressively. We site ADUs to avoid root zones and pull the right permits when proximity is unavoidable.
