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 Long Beach-only numbers, and Long Beach is in Los Angeles County.
What the local record shows
Typical home values in Long Beach are up 17.3% over five years, and typical rent is $2,422 a month. Of the ten cities in our service area, Long Beach has the highest ADU permit total for 2021 to 2025. Long Beach reported ADU building permits issued every year from 2021 to 2025: 434, 495, 670, 747, and 644. That is 2,990 in total.
