Accessory Dwelling Unit (ADU) Standards
On June 12, 2018 the Santa Monica City Council adopted modifications to the Accessory Dwelling Unit (ADU) standards. These revised standards become effective on July 12, 2018.
The following are the key changes:
- Maximum Size:
- 650 SF for parcels 6,000 SF and smaller
- 800 SF for parcels greater than 6,000 SF
- Second Story Size:
- No limit; however, the second story cannot exceed the area of the first story
- ADUs must still be clearly subordinate to the main dwelling unit on the parcel in terms of size (i.e. floor area), location, and appearance.
ADUs continue to be excluded from R1 parcel coverage calculations per the R1 Interim Zoning Ordinance currently in effect. The ADU development standards will be revisited as part of the forthcoming effort to review and update the R1 Single-Unit Residential development standards over the next 12-18 months.

R1 Interim Zoning Ordinance
On February 13, 2018, the Santa Monica City Council adopted an interim ordinance that temporarily reduces the size of new construction in R1 single-unit residential zoning districts pending the completion of a comprehensive review of R1 zoning standards. The interim ordinance comes on the heels of Council’s January 9, 2018 direction to prioritize a comprehensive review of R1 development standards. Although the ordinance does not take effect until March 16, 2018, the changes are retroactive and will apply to any project in the R1 zone submitted after February 23, 2018. You can look up the zoning for your home on the interactive zoning map to determine whether this ordinance applies to you.
The following is a summary of changes:
Building Height: Max 28 feet
Parcel Coverage: Max 50% total on a sliding scale, Max 20% on second story
Second Floor Decks and Balconies: Max aggregate of 400 square feet
Accessory Dwelling Units: Excluded from parcel coverage calculations
The interim ordinance may be extended for a period up to five years pending adoption of permanent revised standards. The comprehensive review process is anticipated to begin in the first part of 2019 and will involve a significant public engagement process to identify the appropriate scale of new construction and additions in R1 neighborhoods.
