Santa Monica / ADU construction

ADU construction in Santa Monica

Santa Monica publishes guidance for both ADUs and junior ADUs (JADUs) and references its local code. That makes a JADU inside the existing house a real option to weigh alongside a detached unit or garage conversion.

01

What shapes this work here

ADU or JADU

A junior unit works inside the existing home, while an ADU can be detached, attached or converted. The City's page explains both; the choice changes scope dramatically.

Compact lots

On smaller lots, the space between structures and the route for materials decide feasibility of a new detached unit more than floor-plan wishes.

Coastal resources are parcel-specific

Check the City's property resources for coastal program questions; don't assume they apply or don't.

First steps in this city

  1. 01

    Read ADU and JADU guidance

    Note which type fits: inside the house, attached, detached or conversion.

  2. 02

    Check the property lookup

    Record zoning and any coastal or preservation flags.

  3. 03

    Measure spaces between structures

    Distances between house, garage and property lines shape every option.

  4. 04

    Compare two options in writing

    Use the same scope list for each so differences are visible.

03

What the scope usually covers

  • Site access, staging and protection of the main house
  • New foundation, or evaluation of an existing slab and shell
  • Utility routes from the main service to the unit
  • Interior build-out, final inspections and handover documents
  • For a JADU: separation, entry and kitchen provisions within the existing house
04

Bring to the first conversation

  • Property address
  • Site sketch with structures, trees and utility locations
  • Intended use of the unit
  • Photos of the garage interior and slab if converting
  • Floor plan of the existing house if a JADU is an option
