ADUs in Norwalk:The Local Numbers

Norwalk homeowners are building ADUs, and the public record shows it. These are the city's own home value, rent, and permit numbers, plus what appraisal research says ADUs add.

What the research shows

Statewide, appraisal data from the Federal Housing Finance Agency shows California properties with an ADU had a median appraised value of $1,064,000 in 2023, against $715,000 for properties without one. FHFA notes the higher growth in appraised value for properties with ADUs requires further analysis, so this is a comparison of medians, not a promise for any one home. A peer-reviewed study of Los Angeles found that ADU presence raises a parcel's assessed value and selling price by 7% to 9%. Both are statewide or City of Los Angeles figures, not Norwalk-only numbers, and Norwalk is in Los Angeles County.

What the local record shows

Typical home values in Norwalk are up 21.1% over five years, and typical rent is $2,697 a month. Of the ten cities in our service area, Norwalk has the lowest typical home value. Norwalk reported ADU building permits issued every year from 2021 to 2025: 84, 96, 58, 81, and 113. That is 432 in total.
