Santa Monica remodeling & ADUs
Santa Monica publishes property-planning resources and its own ADU guidance. Coastal review is a question for the parcel, not an assumption about every home.
Review authority
City of Santa Monica
Rules and approvals depend on address and scope. This is general education, not a parcel determination.
Think in whole-home terms
Sequence matters as much as design.
Start with the city’s property-regulation lookup and decide whether changes affect the exterior or only the interior. If the parcel has coastal or preservation constraints, confirm the relevant review before committing to exterior work.
Consider an ADU
Compare options after reviewing the site.
The city’s ADU page identifies the local code section. Compare a garage conversion with new detached space only after documenting existing structure, service routes and the property’s planning context.

Practical questions for the first conversation, not a permit determination.
Check the property
Check city property resources for any coastal or preservation review before assuming exterior changes can proceed.
Coordinate the scope
Separate interior reconfiguration from envelope work; compare garage conversion with a new unit after documenting shell and services.
First document
Property lookup, exterior photographs and a list separating inside from outside work.

A local question
Does every Santa Monica remodel need coastal review?
No blanket answer applies. Check the parcel and the type of work against the city’s planning resources and ask the city if coastal review is triggered.
